There are propositions that upon understanding them it seems that one can “just see” that they are necessary or impossible. A commonly discussed example is the claim that it is not possible for an object to be red and green all over at the same time. My purpose in this paper is to account for how it is that such beliefs are justified. I begin by criticizing a suggestion defended lately by Laurence BonJour and others. BonJour argues that because these (...) beliefs are necessarily true external factors are irrelevant to their epistemic status. This is how BonJour can defend a foundationalist account of the a priori while at the same time attacking foundationalism with respect to empirical knowledge. I argue that this view of the a priori is mistaken. External factors are relevant even in the case of those a priori beliefs it seems we can just see to be true. I defend an alternative account of the justification of such beliefs. I argue that these beliefs may be justified in virtue of their being the products of a basic belief-forming mechanism one has no reason to distrust. In particular, I argue that this approach can be employed to account for the non-inferential justification of a priori beliefs without falling prey to the line of objections BonJour lodges against other forms of foundationalism.

Performance-based epistemology conceives the normativity involved in epistemic evaluation as a special case of a pattern of evaluation that can be applied to any domain where there are agents that carry out performances with an aim. This volume presents new essays by leading epistemologists who discuss key issues concerning the foundations and applications of this approach. The essays in Part I examine some foundational issues in the conceptual framework. They address questions central to the debate, including the compatibility of apt (...) success with some forms of luck; the connection between aptness and a safety condition for knowledge; the fallibility of perceptual recognitional abilities; actual-world reliabilism and reliabilism about epistemic justification; the nature of the agency required to make a cognitive success truly one's own; the basic conceptual framework of performance-based epistemology. Part II explores Sosa's epistemology of a priori intuition; internalist objections to Sosa's views on second-order knowledge; the roles that epistemic agency is meant to play in performance-based epistemology; the value that second-order reflection may have; epistemic incompetence; and the problem of epistemic circularity and criticises Sosa's alternative solution.

The past twenty-five years have seen a major renewal of interest in the topic of a priori knowledge. In the sixteen essays collected here, which span this entire period, philosopher Albert Casullo documents the complex set of issues motivating the renewed interest, identifies the central epistemological questions, and provides the leading ideas of a unified response to them.

This book brings together previously unpublished work which looks at issues concerning the foundations and applications of a prominent branch of virtue epistemology: “performance-based epistemology”. The chapters in Part I examine some foundational issues in the conceptual framework of PBE: the relations between apt success and luck; the connection between aptness and a safety condition for knowledge; the fallibility of competences; the kind of reliability needed for knowledge and justification; the nature of epistemic agency; and some ways of enriching (...) the basic conceptual framework of PBE. The chapters in Part II discuss the application of PBE to outstanding problems in contemporary epistemology, such as the nature of a priori intuition; internalist objections to epistemic externalism; the roles that epistemic agency is meant to play in the acquisition of knowledge; the value of second-order reflection; the nature of some epistemic incompetences; and the problem of epistemic circularity.

A priori reflection, common sense and intuition have proved unreliable sources of information about the world outside of us. So the justification for a theory of the categories must derive from the empirical support of the scientific theories whose descriptions it unifies and clarifies. We don’t have reliable information about the de re modal profiles of external things either because the overwhelming proportion of our knowledge of the external world is theoretical—knowledge by description rather than knowledge by acquaintance. This undermines (...) the traditional idea that to be an object of category C is to be an object with such- and-such characteristic possibilities of combination. But this is no loss because de re modal thought lacks utility for creatures like us. (shrink)

It is a platitude in epistemology to say that knowledge excludes luck. Indeed, if one can show that an epistemological theory allows ‘lucky’ knowledge, then that usually suffices to warrant one in straightforwardly rejecting the view. Even despite the prevalence of this intuition, however, very few commentators have explored what it means to say that knowledge is incompatible with luck. In particular, no commentator, so far as I am aware, has offered an account of what luck is (...) and on this basis identified what it means for a true belief to be non-lucky. It is just such a view that I propose, however, and I hope to give a flavour of what this strategy involves here. In particular, I have two goals in this paper. The first is to outline the general contours of the position and show how such a view can account for the attraction of adducing a safety condition on knowledge, with all the epistemic benefits that this principle holds. Relatedly, I will also explain how an anti-luck epistemology can assist us in determining the best formulation of this principle. The second goal of the paper is to show anti-luck epistemology in action by highlighting how such a view can deal with the various problems posed by lottery-style examples. (shrink)

Epistemological naturalists reject the demand for a priori justification of empirical knowledge; no such thing is possible. Observation reports, being the foundation of empirical knowledge, are neither justified by other sentences, nor certain; but they may be agreed upon as starting points for inductive reasoning and they function as implicit definitions of predicates used. Making inductive generalisations from observations is a basic habit among humans. We do that without justification, but we have strong intuitions that some inductive generalisations will fail, (...) while for some other we have better hopes. Why? This is the induction problem according to Goodman. He suggested that some predicates are projectible when becoming entrenched in language. This is a step forward, but not entirely correct. Inductions result in universally generalised conditionals and these contain two predicates, one in the antecedent, one in the consequent. Counterexamples to preliminary inductive generalisations can be dismissed by refining the criteria of application for these predicates. This process can be repeated until the criteria for application of the predicate in the antecedent includes the criteria for the predicate in the consequent, in which case no further counterexample is possible. If that is the case we have arrived at a law. Such laws are implicit definitions of theoretical predicates. An accidental generalisation has not this feature, its predicates are unrelated. Laws are said to be necessary, which may be interpreted as ‘“Laws” are necessarily true’. ‘Necessarily true’ is thus a semantic predicate, not a modal operator. In addition, laws, being definitions, are necessarily true in the sense of being necessary assumptions for further use of the predicates implicitly defined by such laws. Induction, when used in science, is thus our way of inventing useful scientific predicates; it is a heuristic, not an inference principle. (shrink)

Justification as Ignorance offers an original account of epistemic justification as both non-factive and luminous, vindicating core internalist intuitions without construing justification as an internal condition knowable by reflection alone. Sven Rosenkranz conceives of justification, in its doxastic and propositional varieties, as a kind of epistemic possibility of knowing and of being in a position to know. His account contrasts with recent alternative views that characterize justification in terms of the metaphysical possibility of knowing. Instead, he develops a suitable non-normal (...) multi-modal epistemic logic for knowledge and being in a position to know that respects the finding that these notions create hyperintensional contexts. He also defends his conception of justification against well-known anti-luminosity arguments, shows that the account allows for fruitful applications and principled solutions to the lottery and preface paradoxes, and provides a metaphysics of justification and its varying degrees of strength that is compatible with core assumptions of the knowledge-first approach and disjunctivist conceptions of mental states.

Perception and intuition are our basic sources of knowledge. They are also capacities we deliberately improve in ways that draw on our knowledge. Elijah Chudnoff explores how this happens, developing an account of the epistemology of expert perception and expert intuition, and a rationalist view of the role of intuition in philosophy.

According to the No-Luck-Thesis knowledge possession is incompatible with luck – one cannot know that p if the truth of one’s belief that p is a matter of luck. Recently, this widespread opinion was challenged by Peter Baumann, who argues that in certain situations agents do possess knowledge even though their beliefs are true by luck. This paper aims at providing empirical data for evaluating Baumann’s hypothesis. The experiment was designed to compare non-philosophers’ judgments concerning knowledge (...) and luck in one case that Baumann takes to be in favor of his claim and other cases where, according to him, absence of knowledge coincides with luck. The results show that the cases do not differ in a significant way between each other with respect to verdicts regarding knowledge and luck. In all cases subjects were more reluctant to judge that the ‘Gettierized’ belief is knowledge and more likely to judge that it is true by luck in comparison to a belief that is an uncontroversial instance of knowledge. However, the negative relationship between knowledge and luck ascriptions predicted by the No-Luck-Thesis was almost absent. The data raise some doubts about the No-Luck-Thesis, but the reasons for doubt are different than what Baumann expected. (shrink)

It is alleged that the causal inertness of abstract objects and the causal conditions of certain naturalized epistemologies precludes the possibility of mathematical know- ledge. This paper rejects this alleged incompatibility, while also maintaining that the objects of mathematical beliefs are abstract objects, by incorporating a naturalistically acceptable account of ‘rational intuition.’ On this view, rational intuition consists in a non-inferential belief-forming process where the entertaining of propositions or certain contemplations results in true beliefs. This view is free of any (...) conditions incompatible with abstract objects, for the reason that it is not necessary that S stand in some causal relation to the entities in virtue of which p is true. Mathematical intuition is simply one kind of reliable process type, whose inputs are not abstract numbers, but rather, contemplations of abstract numbers. (shrink)

This PhD thesis provides an extended evaluation of evolutionary debunking arguments in meta-ethics. Such arguments attempt to show that evolutionary theory, together with a commitment to robust moral objectivity, lead to moral scepticism: the implausible view that we lack moral knowledge or that our moral beliefs are never justified (e.g. Joyce 2006, Street 2005, Kahane 2011). To establish that, these arguments rely on certain epistemic principles. But most of the epistemic principles appealed to in the literature on evolutionary debunking arguments (...) are imprecise, confused or simply implausible. My PhD aims to rectify that. Informed by debates in cutting-edge contemporary epistemology, Chapter 1 distinguishes three general, independently motivated principles that, combined with evolution, seem to render knowledge of robustly objective moral facts problematic. These epistemic principles state that (i.) our getting facts often right in a given domain requires explanation – and if we cannot provide one, our beliefs about that domain are unjustified; (ii.) higher-order evidence of error undermines justification; and (iii.) for our beliefs to be justified, our having them must be best explained by the facts they are about. Chapters 2-4 develop and critically assess evolutionary debunking arguments based on those principles, showing that only the one inspired by (iii.) succeeds. Chapter 2 investigates the argument that evolution makes explaining why we get moral facts often right impossible. I argue that Justin Clarke-Doane’s recent response (2014, 2015, 2016, 2017) works, yet neglects an issue about epistemic luck that spells trouble for robust moral objectivity. Chapter 3 discusses the argument that evolution provides higher-order evidence of error regarding belief in robustly objective moral facts. I show that such an argument falls prey to Katia Vavova’s (2014) self-defeat objection, even if evolutionary debunkers tweak their background view on the epistemic significance of higher-order evidence. Chapter 4 develops the argument that evolution, rather than robustly objective moral facts, best explains why we hold our moral beliefs. I offer a systematic, comprehensive defence of that argument against Andreas Mogensen’s (2015) charge of explanatory levels confusion, Terrence Cuneo’s (2007) companion in guilt strategy, and David Enoch’s (2012, 2016) appeal to deliberative indispensability. Chapter 5 brings everything together. It investigates whether robust moral objectivity survives the worry about epistemic luck raised in Chapter 2 and the explanatory challenge developed in Chapter 4. Making progress, however, requires a better idea of how we form true, justified beliefs about and acquire knowledge of robustly objective moral facts. Since it offers the most popular and best-developed epistemology of robustly objective morality, my inquiry in Chapter 5 focuses on contemporary moral intuitionism: the view that moral intuitions can be the source of basic moral knowledge. I argue that its success is mixed. While moral intuitionism has the conceptual tools to tackle the problem of epistemic luck from Chapter 2, it cannot insulate knowledge of robustly objective moral facts against the sceptical worry raised by the evolutionary debunking argument developed in Chapter 4. Thus, evolutionary theory, together with a commitment to robust moral objectivity, does lead to a form of unacceptable moral scepticism. (shrink)

I explain why, from the perspective of knowledge-centric anti-luck epistemology, objective act consequentialist theories of ethics imply skepticism about the moral status of our prospective actions and also tend to be self-defeating, undermining the justification of consequentialist theories themselves. For according to knowledge-centric anti-luck epistemology there are modal anti-luck demands on both knowledge and justification, and it turns out that our beliefs about the moral status of our prospective actions are almost never able to satisfy these demands (...) if objective act consequentialism is true. This kind of applied moral skepticism introduces problematic limits on our ability to use objective act consequentialism’s explanatory power as evidence for its truth. This is, in part, a product of higher-order defeat as I explain in the final section. There is, however, a silver lining for objective act consequentialists. For there is at least one type of objective act consequentialism, prior existence consequentialism, that is poised to avoid at least some of the epistemic problems discussed in this paper. (shrink)

Anti-Luck Virtue Epistemology (ALVE) states that for S to have knowledge, S must have a virtuously formed safe true belief. S’s belief that p is safe if, in most near-by possible worlds where S’s belief is formed in the same manner as in the actual world, S’s belief is true. S’s safe belief that p is virtuously formed if S’s safe belief is formed using reliable and well-integrated cognitive processes and it is to S’s credit that she formed the (...) belief. In this paper, I offer a novel counterexample to ALVE. I offer a case where an individual forms a belief on the basis of divine revelation. Intuitively the person has knowledge, but ALVE predicts otherwise. The upshot is not only that we have a counter example to ALVE, but also, that ALVE may not serve the needs of an adequate religious epistemology. (shrink)

In the epistemology of his middle period, Plato repeatedly describes the alleged ‘intellection of true reality’ in terms of sight, vision, illumination, or touch. Does this show more than Plato’s preference for optic and haptic metaphors? Should we assume that this goes back to a specific reason to be found in his underlying epistemological position? On the traditional reading, Plato actually wants to defend a sort of intuitionism. According to this still wide-spread reading, he claims that there is a very (...) particular way of grasping Forms: Philosophers manage to come into a sort of direct contact with intelligible objects. Intellection is thus conceived as a quasi-visual presence of intelligible Forms. In our contribution, we want to challenge this interpretation by raising several objections against it. Surprisingly, there exists a close parallel in Aristotelian scholarship: Although Aristotle’s epistemology is built on considerably different foundations, there is an interpretative tradition according to which one has to assume a strict discontinuity between the methodical procedure and the intellection of the highest epistemic objects. As for Plato, we want to refuse an interpretation of Aristotle based on a concept of intuition characterized by the following features: Intuition is a specific way of gaining knowledge. It is independent of empirical conditions and leads to apriori knowledge. It consists of some experience of evidence or is accompanied by it. Knowledge gained by this kind of intuition does not need any further argument or justification. (shrink)

The problem of epistemic luck arises when a person has a true belief that is only true by luck. Before Gettier, it was believed that the element of justification would be sufficient for knowledge; but he showed that it is possible to have a justified true belief that is not an example of knowledge because of the intrusion of luck. Duncan Pritchard has examined epistemic luck in an extensive and detailed manner. He offers a modal account (...) of luck based on two elements: a possible-worlds analysis of counterfactual conditions and a significance condition for the factors that make the truth of the belief lucky. Pritchard argues for the superiority of this account to those that focus on whether the truth of the belief is “accidental” and on whether the believer has sufficient control over the belief. Epistemic luck may be “reflective” or “veritic”. Both undermine knowledge claims, although Pritchard gives the central role to veritic luck in his anti-luck epistemology, which is based on two elements: a safety principle and a condition to ensure that the cognitive faculties of the agent are not impaired. In this article, we will describe, analyze, and subsequently, evaluate the viewpoint of Pritchard. In addition to the critiques offered by others, ambiguities in his counterfactual account of luck and other components of his theory detract from his theory. (shrink)

Two different versions of epistemological disjunctivism have recently been upheld in the literature: a traditional, Justified True Belief Epistemological Disjunctivism (JTBED) and a Knowledge First Epistemological Disjunctivism (KFED). JTBED holds that factive reasons of the form “S sees that p” provide the rational support in virtue of which one has perceptual knowledge, while KFED holds that factive reasons of the form “S sees that p” just are ways of knowing that p which additionally provide justification for believing that p. We (...) argue that both accounts remain ultimately unsatisfactory. JTBED faces two formidable problems: first, it cannot account for animal knowledge, and, second, it does not offer a satisfactory account of how we access factive reasons. Although KFED can solve these two problems, it has some problems of its own. While intuitively knowledge is logically stronger than justified belief, on KFED it turns out to be weaker: knowledge does not entail justified belief, but justified belief does entail knowledge. Nevertheless, disjunctivists are right on at least a couple of points: we standardly justify our perceptual beliefs by appealing to factive reasons such as seeing that p and so factive reasons ought to play some role in our theory of justification. In addition, KFED’s account of our access to factive reasons also is spot on. Rather than going disjunctivist, these insights can be suitably incorporated into a Knowledge First Virtue Epistemology (KFVE). (shrink)

Contextualism in philosophy of language and in epistemology are two distinct but closely entangled projects. The epistemological thesis is grounded in a semantic claim concerning the context-sensitivity of the predicate “know”: we gain insight into epistemological problems by investigating our linguistic intuitions concerning knowledge attribution sentences. Our aim here is to evaluate the plausibility of a project that takes the opposite starting point: the general idea is to establish the semantic contextualist thesis on the epistemological one. According to semantic contextualism, (...) virtually no sentences of a natural language express complete propositions – meaning underdetermines truth conditions. In our paper, instead of assuming the traditional view of meaning in terms of truth conditions, we suggest that a theory of meaning as justification may shed new light on the contextualist approach. We thus show how the notion of justification can be contextualized, arguing that our attempt provides an interesting and quite straightforward way of contextualizing meaning. (shrink)

In this work Pollock attempts to recast the epistemological enterprise. Traditional epistemology has been centered on the search for truth conditions. It has been assumed that unless these are found the sceptic’s attack on knowledge claims cannot be conclusively answered. Pollock contends that traditional epistemologists have been barking up the wrong tree. The problem of epistemology is not to prove the trustworthiness of the justification condition. The proper task of epistemologists is to reveal the logical connection between the source of (...) our knowledge and the knowledge the source provides. This is to be done through an analysis of the meaning of statements, and the meaning of a statement is determined by the "justification conditions of it and its denial." Epistemological issues, such as perception, other minds, historical knowledge, a priori knowledge, amount to "nothing more than describing the justification conditions for statements in the different areas of knowledge." But, then what is meant by "justification conditions"? (shrink)

Pure virtue epistemology faces the fake barn challenge. This paper explains how it can be met. Thus, it is argued that the thought experiment contains a hidden ambiguity concerning the visual ability typically ascribed to, or denied, fake barn subjects. Disambiguation shows fake barn subjects to have limited knowledge of the target proposition. This accords with a pure virtue-theoretic conception of knowledge that predicts and explains all the intuitions elicited by the thought experiment. As a result, the relationship between knowledge, (...) luck and ability is illuminated, and our epistemological theorizing improved. (shrink)

There is a widely shared belief in contemporary epistemology that propositional knowledge is incompatible with certain kinds of luck, most of all with so called veritic luck. A subject is veritically lucky in his or her belief that p if this belief is true not due to its foundations (for example, reasons which an agent has to believe that p) but by mere accident. The acceptance of the thesis of incompatibility of knowledge with this kind of luck (...) led to significant modifications of a popular modern epistemological tripartite analysis of propositional knowledge according to which subject knows that p if and only if he or she believes that p is true, p is actually true, and an agent’s belief that p is true is justified. In his famous paper “Is True Justified Belief Knowledge” E. Gettier demonstrated that true justified belief may not be knowledge. The core of the problem is that in the cases described by Gettier and the like an agent’s belief, though justified, is true by accident. This gave rise to a set of theories introducing additional conditions of knowledge which could exclude veritic luck. In this paper the author critically discusses main modifications of the tripartite concept of knowledge aimed at making it independent on veritic luck, and show that they are unable to solve this problem. He agrees with those who think that the very thesis of incompatibility of knowledge with veritic luck is wrong. But he disagrees that all kinds of veritic luck are compatible with knowledge: the author supposes that good veritic luck is compatible with knowledge only when it compensates some negative effect of antecedent bad epistemic luck. According to this view original Gettier examples are not cases of knowledge whereas broken-clocks case and fake-barns case are. This account allows treating many classic cases of dependence of knowledge on luck as cases of knowledge-acquirement, but in the same time it excludes the inclusion into the class of knowledge such intuitively irrelevant outcomes as lucky guess and wishful thinking.

I present an epistemological puzzle about perceptual knowledge and its relation to the evaluation of probabilities. It involves cases, concerning a given subject S and a proposition P in a determinate context, where apparently: S has perceptual knowledge of P; the epistemic justification S has for believing Not-P is much greater than her epistemic justification for believing P. If those two theses were true, the following very plausible epistemological principle would fail: If S knows P, then the epistemic justification S (...) has for believing Not-P is not greater than her epistemic justification for believing P. I offer a solution to the puzzle, which is compatible with basic intuitions and theses of orthodox Bayesianism. (shrink)

In the first part of the dissertation, chapters 1 to 3, I criticize several views which tend to set philosophy apart from other cognitive achievements. I argue against the popular views that 1) Intuitions, as a sui generis mental state, are involved crucially in philosophical methodology 2) Philosophy requires engagement in conceptual analysis, understood as the activity of considering thought experiments with the aim to throw light on the nature of our concepts, and 3) Much philosophical knowledge is a priori. (...) I do not claim to have a proof that nothing in the vicinity of these views is correct; such a proof might well be impossible to give. However, I consider several versions, usually prominent ones, of each of the views, and I show those versions to be defective. Quite often, moreover, different versions of the same worry apply to different versions of the same theory. In the fourth chapter I discuss the epistemology of the judgements involved in philosophical thought experiments, arguing that their justification depends on their being the product of a competence in applying the concepts involved, a competence which goes beyond the possession of the concepts. I then offer, drawing from empirical psychology, a sketch of the form this cognitive competence could take. The overall picture squares well with the conclusions of the first part. In the last chapter I consider a challenge to the use of thought experiments in contemporary analytic philosophy coming from the ‘experimental philosophy’ movement. I argue that there is no way of individuating the class of hypothetical judgements under discussion which makes the challenge both interesting and sound. Moreover, I argue that there are reasons to think that philosophers possess some sort of expertise which sets them apart from non-philosophers in relevant ways. (shrink)

The aim of this paper is to examine the idea of metamathematical deduction in Hilbert’s program showing its dependence of epistemological notions, specially the notion of intuitive knowledge. It will be argued that two levels of foundations of deduction can be found in the last stages (in the 1920s) of Hilbert’s Program. The first level is related to the reduction – in a particular sense – of mathematics to formal systems, which are ‘metamathematically’ justified in terms of symbolic manipulation. The (...) second level of foundation consists in warranting epistemologically the validity of the combinatory processes underlying the symbolic manipulation in metamathematics. In this level the justification was carried out with the aid of notions from modern epistemology, particularly the notion of intuition. Finally, some problems concerning Hilbert’s use of this notion will be shown and it will be compared with Brouwer’s. (shrink)

Broadly speaking, a naturalistic approach to epistemology seeks to explain human knowledge – and justification in particular – as a phenomenon in the natural world, in keeping with the tenets of naturalism. Naturalism is typically defined, in part, by a commitment to scientific method as the only legitimate means of attaining knowledge of the natural world. Naturalism is often thought to entail empiricism by virtue of this methodological commitment. However, scientific methods themselves may incorporate a priori elements, so empiricism does (...) not follow from the methodological commitments of naturalism alone. And given a suitably-naturalistic conception of the a priori, a priori forms of justification may be compatible with naturalism generally. A priori justification is, in principle, compatible with naturalism – and hence naturalistic epistemologies – if the a priori is understood in a way that is free of some of the inessential properties that have been associated with the concept. I argue that some of the more prominent strategies for accommodating normative notions within a naturalistic framework allow for the possibility of a priori justification. These include reliabilism, instrumental rationality, and nonfactualism about justification. A priori justification thus need not be seen as standing in opposition to all naturalistic epistemologies. It is only with nonnormative naturalistic epistemologies that a priori justification per se is incompatible, and this only because the notion of justification itself has no role to play within a nonnormative approach to epistemology.

The idea that knowledge as an individual mental attitude with certain propositional content is not only true justified belief but a belief the truth of which does not result from any kind of luck, is widely spread in contemporary epistemology. This account is known as anti-luck epistemology. A very popular explanation of the inconsistency of that concept of knowledge with the luck-dependent nature of truth (so called veritic luck taking place when a subject’s belief could not (...) be true if not by mere coincidence) presumes that the status of propositional knowledge crucially depends on the qualities of actions that result in the corresponding belief, or processes backing them, which reflect the socalled intellectual virtues mainly responsible for subject’s relevant competences. This account known as Virtue Epistemology presumes that if a belief is true exclusively or mainly due to its dependence on intellectual virtues, it just cannot be true by luck, hence no place for lucky knowledge. But this thesis is hard to prove given the existence of true virtuous beliefs which could nevertheless be false if not for some lucky (for the knower) accident. This led to an appearance of virtue epistemological theories aimed specifically at an assimilation of such cases. Their authors try to represent the relevant situations as such where the contribution of luck is not crucial whereas the contribution of virtues is crucial. This article provides a critical analysis of the corresponding arguments as part of a more general study of the ability of Virtue Epistemology to provide justification for the thesis of incompatibility of propositional knowledge with veritic luck. It is shown that there are good reasons to doubt that Virtue Epistemology can do this. (shrink)

The Contours of Christian Philosophy series will consist of short introductory-level textbooks in the various fields of philosophy. These books will introduce readers to major problems and alternative ways of dealing with those problems. These books, however, will differ from most in that they will evaluate alternative viewpoints not only with regard to their general strength, but also with regard to their value in the construction of a Christian world and life view. Thus, the books will explore the implications of (...) the various views for Christian theology as well as the implications that Christian convictions might have for the philosophical issues discussed. It is crucial that Christians attain a greater degree of philosophical awareness in order to improve the quality of general scholarship and evangelical theology. (shrink)

The paper focuses on some puzzles about Carnap's intended epistemological point in the "completion" and "generalization" of the Anschauungsraum in sec. II of Der Raum (leaving aside the technical problems which also arise). Since any global structure at all requires that eidetic intuition be supplemented with freely-chosen postulates and/or intuitively unmotivated generalizations, it is unclear, as several authors have pointed out, how and in what sense "intuitive space" as a whole represents a distinctive, a priori contribution to our knowledge. I (...) suggest a way of approaching this issue based on Carnap's sources -- in particular, Husserl and Driesch, both of whom he repeatedly claims to be following. The idea of a severely finite realm of possible intuition, which both requires and allows supplementation with an infinite conceptual structure, is central to Husserl's thought, and, I argue, it would be natural for Carnap to rely on it in attempting to reconcile Husserlian eidetic intuition with the general theory of relativity. That this larger conceptual structure owes its details to free postulation is, on the other hand, decidedly un-Husserlian. But here, I claim, Carnap takes his cue from Driesch's view, in the first edition of the Ordnungslehre, that natural actuality is the result of a certain demand for order: we demand such order in natural things and reject as non-actual (hallucinatory, dreamed, etc.) whatever nature-like elements of experience fail to fit into it. In conclusion I suggest that more radical versions of this particular constellation of ideas provide the key to understanding much of Carnap's later thought. (shrink)

Knowledge closure is the claim that, if an agent S knows P, recognizes that P implies Q, and believes Q because it is implied by P, then S knows Q. Closure is a pivotal epistemological principle that is widely endorsed by contemporary epistemologists. Against Knowledge Closure is the first book-length treatment of the issue and the most sustained argument for closure failure to date. Unlike most prior arguments for closure failure, Marc Alspector-Kelly's critique of closure does not presuppose any particular (...) epistemological theory; his argument is, instead, intuitively compelling and applicable to a wide variety of epistemological views. His discussion ranges over much of the epistemological landscape, including skepticism, warrant, transmission and transmission failure, fallibilism, sensitivity, safety, evidentialism, reliabilism, contextualism, entitlement, circularity and bootstrapping, justification, and justification closure. As a result, the volume will be of interest to any epistemologist or student of epistemology and related subjects. (shrink)

The contributors to this volume engage with issues of normativity within naturalised philosophy. The issues are critical to naturalism as most traditional notions in philosophy, such as knowledge, justification or representation, are said to involve normativity. Some of the contributors pursue the question of the correct place of normativity within a naturalised ontology, with emergentist and eliminativist answers offered on neighbouring pages. Others seek to justify particular norms within a naturalised framework, the more surprising ones including naturalist takes on the (...) a priori and intuitions. Finally, yet others examine concrete examples of the application of norms within particular epistemic endeavours, such as psychopathology and design. The overall picture is that of an intimate engagement with issues of normativity on the part of naturalist philosophers – questioning some of the fundamentals at the same time as they try to work out many of the details.

Philosophy and science employ abstract hypothetical scenarios- thought experiments - to illustrate, defend, and dispute theoretical claims. Since thought experiments furnish no new empirical observations, the method prompts two epistemological questions: whether anything may be learnt from the merely hypothetical, and, if so, how. Various sceptical arguments against the use of thought experiments in philosophy are discussed and criticized. The thesis that thought experiments in science provide a priori knowledge through non-sensory grasping of abstract entities is discussed and rejected. The (...) thesis that thought experimentation consists in manipulations of mental models is examined and found to be of limited epistemological relevance. It is argued that thought experiments are associated with characteristic arguments in a manner similar to ordinary experiments. It is further argued that thought experiments function in the same way as experiments in general: by providing premises for their associated arguments. Like other experiments, a thought experiment is successful when the premises it provides are true. This holds both for philosophical and scientific thought experiments. An argument schema is proposed and shown to be a formal analogue to that associated with ordinary experiments; similar in being subject to epistemological holism; but differing in being modal: in employing statements about possibility and necessity. The evaluation of thought experiments thus depends on how modal statements may be justified. Intuition and conceivability are discussed as sources of modal justification and found problematic. Instead it is suggested that evaluation proceed by accommodation of the statements describing the experiment's hypothetical scenario. The method of accommodation is developed and applied to five influential thought experiments in philosophy: the brain in a vat; Putnam's Twin Earth; Burge's arthritis example; Searle's Chinese Room; and Newcomb's problem. Its application shows some of these to be failed, others to be successful only relative to controversial philosophical doctrines. (shrink)

In this paper I articulate and defend a view that I call phenomenal dogmatism about intuitive justification. It is dogmatic because it includes the thesis: if it intuitively seems to you that p, then you thereby have some prima facie justification for believing that p. It is phenomenalist because it includes the thesis: intuitions justify us in believing their contents in virtue of their phenomenology—and in particular their presentational phenomenology. I explore the nature of presentational phenomenology as it occurs perception, (...) and I make a case for thinking that it is present in a wide variety of logical, mathematical, and philosophical intuitions.

We explore new connections between the epistemologies of mental rehearsal and suppositional reasoning to offer a novel perspective on skilled behavior and its relationship to practical knowledge. We argue that practical knowledge is "easy" in the sense that, by manifesting one's skills, one has a priori propositional justification for certain beliefs about what one is doing as one does it. This proposal has wider consequences for debates about intentional action and knowledge: first, because agents sometimes act intentionally in epistemically hazardous (...) environments, these justified beliefs do not always rise to the level of (practical) knowledge. Second, practical knowledge is more intimately related to basic knowledge than has been appreciated. Third, an attractive "middle way" opens between the Anscombian tradition of defending a necessary connection between intentional action and practical knowledge and the more recent tradition of explaining away substantive epistemic conditions on intentional action.

This book provides readers with an introduction to epistemology within the Buddhist intellectual tradition. It is designed to be accessible to those whose primary background is in the “Western” tradition of philosophy and who have little or no previous exposure to Buddhist philosophical writings. The book examines many of the most important topics in the field of epistemology, topics that are central both to contemporary discussions of epistemology and to the classical Buddhist tradition of epistemology in India and Tibet. Among (...) the topics discussed are Buddhist accounts of: the nature of knowledge episodes, the defining conditions of perceptual knowledge and of inferential knowledge, the status of testimonial knowledge, and skeptical criticisms of the entire project of epistemology. The book seeks to put the field of Buddhist epistemology in conversation with contemporary debates in philosophy. It shows that many of the arguments and debates occurring within classical Buddhist epistemological treatises coincide with the arguments and disagreements found in contemporary epistemology. The book shows, for example, how Buddhist epistemologists developed an anti-luck epistemology—one that is linked to a sensitivity requirement for knowledge. Likewise, the book explores the question of how the study of Buddhist epistemology can be of relevance to contemporary debates about the value of contributions from experimental epistemology, and to broader debates concerning the use of philosophical intuitions about knowledge.

This work is a departure from traditional investigations of induction. Rather than consider issues related to the justification or construction of a scientific inductive logic, Professor Will exposes, evaluates, and rejects the epistemological framework within which work in the philosophy of induction is usually conducted. He argues that the frustrating difficulties faced in the philosophy of induction are endemic to that theory of knowledge which "resulted from the empiricist criticism and revision of the basic Cartesian view that knowledge is a (...) kind of vision or intuition, that there are certain first intuitions, and that further knowledge consists of consequent intuitions elicited from or founded upon these." According to this view of knowledge, a knowledge claim can be justified in the face of the challenge of philosophical skepticism only if it is either itself indubitable or rests on some foundation that is indubitable. The burden of Will’s work is to show that this foundation or "justification" picture of knowledge is seriously mistaken and must be replaced with a more adequate and more realistic view. Human knowledge, he stresses, is best seen as analogous to a constitution. As human knowledge differs from area to area these constitutions differ, "just as history differs from horticulture and architecture from aviation." However, "collectively they form a huge sprawling entity that represents what may be thought of as the constitution for the institutionalized activity of human knowledge.". (shrink)

The book reconstructs the history of Western ethics. The approach chosen focuses the endless dialectic of moral codes, or different kinds of ethos, moral doctrines that are preached in order to bring about a reform of existing ethos, and ethical theories that have taken shape in the context of controversies about the ethos and moral doctrines as means of justifying or reforming moral doctrines. Such dialectic is what is meant here by the phrase ‘moral traditions’, taken as a name for (...) threads of moral discourse, made in turn of other interwoven threads, including transmission of shared codes, appeals to reform of prevailing custom, rational argument about the justification of some precept on the basis of some shared general teaching or principle, and rational argument about the ultimate basis for principles and justification of authoritative teaching. That is, the approach adopted to the reading of ethical texts depends on a firm belief in the fact that philosophers hardly created any ethical doctrine out of nothing. The main point this book tries to highlight is how different philosophical theories emerged and followed each other as a result of attempts at accounting for what was going on in the world of moral traditions. Changes were propelled by controversies between different schools, and highly abstract arguments were the unintended effects of moves made by controversialists forced to transform (and occasionally to turn upside down) their own doctrines in order to face the challenge posed by other arguments. This is the reason why the book examines not only texts that already enjoy pride of place in the history of philosophy (Aristotle, Kant, Hegel), but also other texts usually treated in the histories of religions (the Bible, the Talmud, the Quran), and others considered to be much less philosophical (Plutarchus, Pufendorf). -/- 1. Plato and a response to ethical scepticism. Two different traditions of morality in VI-V century Greece are described. The birth of philosophical questioning of traditional morality and temporal and spatial variation of custom is described within the context of the v century crisis, the demise of traditional aristocratic and tyrannical rule and the birth of democracy. Two conflicting answers to the challenge are reconstructed, namely conventionalist or immoralist theories formulated by the Sophists and the eudemonist and intellectualist Socratic theory. Plato’s own reformulation of Socrates answer to the Sophists is reconstructed. His psychological views, his classification of the four cardinal virtues and his political theory are described as parts of a unitary system, culminating in an extremely realist moral ontology identifying the idea of the good with the essence of the (moral and extra-moral) world itself. -/- 2. Aristotle and the invention of practical philosophy. Aristotle’s invention of practical philosophy as a field separated from first philosophy is shown to be an implication of his break with Plato moral ultra-realism. Aristotle’s agenda in his moral works is arguably dependent on a polemical intention, namely dismantling Socratic intellectualism. The semi-inductive or virtuously circular method of practical philosophy is illustrated, starting with the received opinions of the better and wiser individuals and trying dialectically to sift what is left of mistake and inconsistence in such opinions, finally trying to correct mistakes and make the overall practical science more consistent. The chapter illustrates then the relationship of individual ethics, or ‘monastics’, with the art and the science of the pater familias, or ‘economics’, and the science of the ruler and citizen, or politics. The nature of virtues, or better, excellences of character, is discussed, highlighting the basic role of hexis, or ‘disposition’. Prudence, or better practical wisdom, is the focus of the chapter. Its relationship with bouleusis or deliberation is examined, and its autonomous status vis-à-vis theoretical knowledge is stressed. -/- 3. Diogenes and philosophy as a way of life. The chapter provides an overview of Hellenistic ethics, which almost amounts to Hellenistic schools of philosophy, in so far as ‘philosophy’ became in these centuries primarily the name for a way of life. The typical character of the Cynical movement is highlighted, that of a school of life, not a school aimed at providing any kind of intellectual training was to be provided. -/- 4. Epicurus and ethics as self-care. The peculiar character of the Epicurean school is described, a combination of a science of well-being aiming, more than at pleasure as in the popular view, at reduction of useless suffering, of unnecessary needs, and at a balanced selection of pleasures of the best and most durable kind. -/- 5. Epictetus and ethics as therapy of the passions. The various phases of Stoicism are described, and the shifting place given to ethics in the Stoic system of idea, culminating in the paradoxical view of ethics, its impossibility in principle notwithstanding, as the only truly significant and necessary part of philosophy. Cicero is treated, showing how his own synthesis of various Hellenistic trends is as a truly philosophical enterprise, deserving serious consideration after one or two centuries when he was confined to the role of literate. Epictetus is chosen as the best example of what the Stoic tradition could yield, an art of living based on sophisticated introspection, in turn aimed at making a kind of cognitive therapy possible, dismantling obnoxious passions at their root by systematically correcting false representations. -/- 6. Philo and the reconciliation of Torah and Platonism. A reconstruction of basic ideas from a few books of the Hebrew Bible is provided, starting with the Prophetic tradition and the focus on God’s mercy as the source of motivation and standard for human behaviour. Then a comparative analysis is undertaken of a parallel tradition, namely the three codifications of the Torā (Law or, better, Instruction), highlighting how a core of moral ideas may be recognized as a basis and preamble of codification of civil law, cultural practice, and regulation of ritual purity. The importance of Leviticus is stressed as the turning point when emphasis mercy, typical of the Prophetic tradition, is combined with the legal tradition, yielding the change in sensibility of the Second Temple time. Philo of Alexandria is described as one of the three leading figures – together with Rabbi Hillel and Rabbi Yeshua – at the apex the emergence of the mentioned new sensibility, gradually including mercy as an essential part of justice and establishing the starting point of both the Rabbinic and the Christian tradition. This consists precisely in the precept of one’s neighbour’s love or of the golden rule, two eventually identical precepts whose meaning is arguably more sober and sensible than the long-lasting Christian tradition deriving from John and Augustine has made us believe and no novelty vis-à-vis so-called Ancient-Testament teachings. -/- 7. Augustine and Christianity as Neo-Platonism. The first section examines the moral doctrines of so-called 'ethical Treaties' from the Talmud, a group of treaties, among which the best known is Pirqé Avot, that were left out of the six "orders" of the canon as they did not fit in any of the six groups of issues ritual or legal on which the division was based. According to Maimonides, their peculiar theme is provided by the Deòt, 'opinions', i.e., mental dispositions, that is, the translation of the Greek term hexeis and Arab akhlak (in turn providing in this language the name for ethics as such). The three topics I reconstruct are: i) the notion of Torah: The Torah is understood as the world order itself, or as the ‘Wisdom’ that existed even before creation and was ‘the tool by which the world was built’; however, the Torah is an earthly and human entity, as it was "received" by humans, and from that very moment belongs to them; ii) the relationship between love of God and love of neighbour; the treaties require us to study and practice the Torah ‘for its own sake’, that is, require us to act out of love, not out of fear or hope of reward; iii) the idea of sanctification of daily life: having disappeared with the destruction of the Temple the possibility of any conflict between liturgical service and everyday life, the latter is assumed to be in itself divine service: to give food to the poor has the same value as sacrifices in the Temple, and as an implication, the insistence become recurrent on the goodness of created things in themselves along with a polemic against ascetic currents. The conclusions drawn are: i) the moral teachings of the Talmud and those of Yeshua are, rather than similar, virtually identical; one may safely say that the precept of love and the golden rule are central ones for all Talmudic rabbis, that mercy plays an indispensable role alongside with justice, and the latter is not a different thing from one’s neighbour’s love; ii) a peculiarity of Talmud rabbis facing Yeshua is the idea of study as worship, and knowledge as a source of justice; but this is an idea of Judaism after the Temple's destruction that cannot be attributed to the Pharisees of Yeshua’s time; iii) the relation of study and practice in the Talmud parallels that between faith and deeds in Paul's epistles, that is, respectively faith or learning are a necessary and sufficient condition to be recognized as righteous , but deeds are the inevitable effect of either faith or learning. The sayings ascribed to Yeshua are examined first, yielding the conclusion that a close equivalent may be found for every saying in Talmudic literature and yet the whole is ascribed to one rabbi, with rather consistent stress on God’s mercy and unconditional forgiving as the mark of true imitation of God. Thus, Yeshua’s teaching is pure Judaism. The third section describes briefly the galaxy of Gnostic currents and Manichaeism, trying to sketch the profile of moral teachings resulting from an encounter of Asian spiritual traditions, Hellenistic lore and sparks of teachings from apocalyptic Jewish currents. The last section summarizes the turbulent history of several encounters between Christian currents and Hellenistic philosophical schools. The first one was with late Cynicism. Recent, rather controversial, literature discovered the jargon and a few topics from the Stoic-Cynical popular philosophy in a few books from the New Testament itself. This, far from proving that Rabbi Yeshua had been influenced by cynic preachers, is a proof of the necessity felt by Christian preachers to translate the original ‘Christian’ teaching into a Greek lexicon deeply impregnated with cynic terminology. The second was with Platonism, yielding the mild and temperate moral teaching of Clemens of Alexandria, teaching the sanctity of nature and the human body, the joy of moderate fruition of ‘natural’ kinds of pleasures, and the beauty of the marital life – in short, the opposite of the standard picture of Medieval Christianity. Ambrose of Milan brings about a different kind of synthesis, namely with Middle Platonism, where Stoic themes prevail. The most shocking case is Augustine, where an early Manichean education is overcome in a former phase by a synthesis of Plotinian Neo-Platonism and Christian preaching, yielding a sustained polemic with the Manicheans and rather optimistic views on life and Creation, the body and sexuality, and Hebrew-Judaic tradition not far from Clemens of Alexandria. In a later phase, occasioned by controversy on the opposite front, with such Christian currents as the Pelagians and Donatists, Augustine comes back to heavily anti-Judaic and world-denying ascetic attitudes where is earlier Manichean upbringing seems to emerge again. The tragedy of medieval Christianity will be the later Augustine’s overwhelming influence. A final section is dedicated to the monastic tradition where a curious mixture of world-denying asceticism with an astonishingly penetrating ‘science’ of introspection emerges. -/- 8. Al Farabi and the reconciliation of Islam and Platonism. The Qurān and the qadit, that is, collections of sayings ascribed to the prophet Muhammad contain a wealth of precepts and catalogues of virtues mirroring moral contents from the Jewish and the Christian traditions, among them the basic notion of imitation of the Deity, where mercy is assumed to be its basic trait. An important tradition within Islam, namely Sufism, stressed to the utmost degree the role of mercy, turning Islam into a mystic doctrine centred on retreat from the world, abandonment to God’s will, and a peaceful and fraternal attitude to our fellow-beings. A secular literary tradition originating in the Sassanid Empire, the literature of advice to the Prince had for a time a widespread influence in the newly constituted Arabic-Islamic commonwealth. In a later phase, the legacy of Hellenic philosophy made its way into the intellectual elite of the Islamic world. The first important legacy was Platonic, and the Republic became the main text for Islamic Platonism. Al-Farabi wrote an enjoyable remake of the Platonic Republic, arguing that the citizen’s virtues were the basis on which the political building needs to rest. The secular lawgiver is enlightened by the light of reason in his everyday practice of governance, but room is made for the Prophet as the voice of revealed truth that confirms and completes the rational truth that philosophy may afford. In a second phase also Aristotelian and Stoic influence were assimilated. Miskawayh’s treatise was the masterwork at the time Arabic philosophy reached its Zenith. It is a treatment of the soul’s diseases and their remedies, combining the Aristotelian doctrine of the golden mean with the Stoic doctrine of the passions and elements of Galenic medicine. Towards the eleventh-twelve centuries a war raged among theologians and philosophers, finally won by the former with disappearance of philosophy as such. The newly established mainstream, yet, was no kind of intolerant fanaticism. It drew from the work of mystic theologian Al-Ghazālī, the best heir of Sufism, teaching a tolerant and peaceful attitude to our fellow-beings and a passive attitude to destiny as an expression of the Divine will. -/- 9. Moshe ben Maimon and the reconciliation of Torah and Aristotelian ethics. The encounter between the Talmudic tradition and Hellenic philosophy had taken place a first time in Alexandria at the time of Philo but the two traditions had parted way again. In fact, the kind of Platonic Judaism founded by Philo survived only within Christianity, in the fourth Gospel and then in writings by Clemens of Alexandria. The Talmudic literature had absorbed just less striking traits from the Hellenic Philosophy, namely an idea of ethics as care of the self and a role for the education of character as propaedeutic to theoretical knowledge. In the Arabic-Islamic world, a second round started when Jewish authors writing in Arabic undertook the task to prove the full compatibility of the tradition deriving from Torah and Platonic philosophy. The culmination of this attempt is provided by Moshe ben Maimon who tried to use Aristotelian ethics as a language into which the teaching from the Pirké Avot could be translated. -/- 10. Thomas Aquinas and the reconciliation of Christian morality and Aristotelian ethics. In the first section the fresh start is described of philosophical ethics in Latin Europe at the turn of the Millennium. In a first phase, Anselm and Peter Abelard built on a Platonic and Augustinian legacy. In this phase. remarkable innovations are introduced, including Abelard’s claim of the obliging character of erring consciousness. In a second phase, the rediscovery of Nicomachean Ethics thanks to Latin translation of Arabic versions gives birth to a new wave of ethical studies, recovering the very idea of Aristotelian practical philosophy, with the potential implication of full legitimization of natural morality, i.e. ethics without Revelation. Aquinas’s ethics is a theological ethics out of which it would be vain to try to extract a self-contained philosophical ethics. His treatment of topics in philosophical ethics, yet, does not boil down to repetition of Aristotelian arguments but is rather a creative reshaping of such arguments. For example, he introduces also in the practical philosophy a first principle parallel to the principle of non-contradiction; and he also carries out a synthesis of Aristotelianism, Stoicism, and neo-Platonism. Even though it is essentially moral theology, Aquinas’s doctrine - unlike Augustine – grants full citizenship to "natural" morality, firstly by rejecting the claim that the corruption of human nature due to the original sin is so radical as to leave "pure nature" incapable of moral goodness. The doctrine is presented in a more sophisticated formulation in a few of the Quaestiones, such as De Malo and De Veritate, in the Summa contra Gentes and in the commentaries to Aristotle than in the famous Summa Theologica, but the latter work includes the only or the largest exposition of some decisive part of the theory. Thus, the Summa Theologica should be read for what it is more than criticized for not being what it was not meant to be. It was not meant to be the brilliant synthesis of all that Reason he had been able to produce with what Revelation had added about which the Neo-Thomists used to dream, but rather a manual for the training of preachers and confessors, where theoretical claims are not too demanding and a few serious tensions are left. Besides a jump between the Prima Secundae and the Secunda Secundae, being the former an essay in virtue theory and the latter a handbook for confessors, the most serious tension is perhaps the one between the ethics of right reason presented in most of Ia-IIae and the eudemonistic ethics developed in quaestiones 1-5 of the same part; the alternative ethical theory which also may be found in Augustine, the Stoic view of a cosmic reason eventually coincident with the moral law, was believed by Anselm (followed by John Duns Scotus and William of Ockham) to be incompatible with eudemonism. It is questionable whether Thomas could reduce the tension proving that it is just an apparent tension, in so far as the right reason and bliss derived from knowledge of God tend to coincide, but this is just a conjecture. Thomas’s ethics is a virtue ethic, not a law-based one, and moral judgment focuses on the virtues, particularly charity, not on the commandments and even less on absolute prohibitions; Thomas, however, would not have considered a drastic alternative between law and the virtues such as the one which has been advanced in late twentieth-century philosophy to be justified. Nonetheless, when it discusses ‘special’ virtues, it ceases to be an ethics of virtue and becomes a disappointing and often contradictory discussion of legal and illegal acts. Such a discussion takes most of the time ‘reasonable’ middle positions on controversial issues but not the alternative approach that Aristotelianism would have made possible; even when some occasional Aristotelian claim shows up, such as money’s barrenness as a reason against usury, this seems to be made by an author who apparently ignores the Aristotelian Thomas of the Prima Secundae. It is an ethic of human autonomy which recognizes the binding character of the individual conscience and, potentially, even a duty to disobey unjust laws. It is true that what Thomas writes in his discussion of death penalty and persecution of heretics is simply disgusting, and yet we should blame Thomas the man, not Thomist ethical theory. Finally, Thomas’s ethics is not ethical ‘absolutism’, as both traditionalist Catholic theologians and secularist enemies of dogmatic morality tend to believe. It is instead an ethic of prudential judgment. Exceptions to this approach – or better results of logical fallacies – are such claims as the absolute character of negative precepts and of the existence of "intrinsically evil acts", claims that simply cease to make sense in the light of Thomas’s own distinction between human act and natural act, carrying consequences Thomas did not live long enough to draw or was not consistent enough to dare to draw. -/- 11. Francisco de Vitoria and casuistry. The first topic illustrated is the discussion about the notion of pura natura, namely the human condition after the original sin and before divine revelation. The core notion was already there in Aquinas but was later developed by Caietanus (Thomas de Vio) with a number of interesting implications: firstly a view of human nature as such much more positive than Augustine’s and his followers’ view, including both Calvinists and Jansenists; secondly, the implication that the philosopher’s morality, as opposed to the Christian’s morality, is a quite respectable kind of morality; thirdly, that theocracy and prosecution of the unfaithful lacked justification, with more far-fetching consequences than Aquinas himself had dared to draw. The second topic is casuistry, a new name for a comparatively older way of thinking, which was already there in late Stoicism and Cicero as well as in the Talmudic literature. This is an approach aimed at yielding probable enough solutions for doubtful cases even in absence of completely safe staring points. The genre developed from medieval reference books for confessors and became by the sixteenth-century a sophisticated tool-box for dealing with various fields of applied ethics. Francisco Vitoria, the main authority of Baroque Scholasticism, was a controversial figure, among the proponents of the new discipline of casuistry and a consistent proponent of more separation between the religious and the civil authority, stricter limits to the legitimacy of war, innate rights of non-Christian nations in the New World based on the notion of pura natura, providing a standard of ‘natural’ goodness, previous to revelation, on which the Indian nations were judged to live in a naturally good condition, provided with the institutions of family, justice, and religion had accordingly a right to full respect by Christian sovereigns. Bartolomé de Las Casas, arguing along similar lines, was the leader of a historical battle in defence of the rights of the Indios. -/- 12. Michel de Montaigne and the art of living. A short description of one of the Renaissance Phyrronism, one of the classical philosophies revived in the fifteenth and sixteenth century. Montaigne combines the sceptical epistemology with an understanding of ethics – indeed of philosophy as a whole – in terms of an art of living inspired by two basic ideas, sagesse, that is, practical wisdom as the only kind of rationality available after theology, science, and tradition have declared bankrupt, and an aesthetic ideal of self-transformation through the art of writing and introspection. -/- 13. Pierre Nicole and neo-Augustinianism. The chapter illustrates first the vicissitudes of Augustinianism newly born after the late medieval triumph of Thomist Aristotelianism in the alternative Protestant and Catholic versions processed by the Calvinists and the Jansenists. Then it illustrates the doctrines of Pierre Nicole, Blaise Pascal’s best disciple, on the impossibility of introspection, on the ubiquity of self-deception, on the incurably evil character of the passion of love, and on the two moralities, the one of the man of the world, the morality of honesty which is indispensable for granting peace and order but devoid of any true value for eternal salvation, since the same external behaviour may be prompted by opposite motivations, and the morality of charity, the only true one but also useless to society. The third topic is Pierre Malebranche’s view of self-deception as a ubiquitous phenomenon accounting for human action and responsibility and his reformulated theory of self-love, no less ubiquitous than for Nicole and yet not as incurably evil, given the distinction between morally indifferent and even necessary amour de soi and vicious amour proper, a distinction on which the whole of Rousseau’s moral and political theory rests. -/- 14. Samuel von Pufendorf and the new science of morality. The chapter is dedicated to the discovery of the idea of a ‘new moral science’. Hugo Grotius is discussed first highlighting the real character of his project, much closer to the Thomist idea of a natural law accessible to non-corrupted human reason when human beings are living in a state of pura natura. Then Hobbes’s combination of scepticism, voluntarism, and conventionalism is described and both the continuity with Grotius’s new science, in the search for non-revealed rational morality, and the break with him, in the adoption of voluntarism and refusal of an intellectualist view of natural law, are illustrated. Pufendorf’s work is illustrated as a synthesis of the two previous attempts and the – up to Schneewind underestimated – paradigmatic example of the new science of morality. -/- 15. Richard Cumberland and consequentialist voluntarism. The chapter gives an overview of eighteenth-century Anglican ethics, noticing how the Cambridge tradition gave special weight to natural theology as opposed to positive or revealed theology – and how two Cambridge fellows, John Gay and Thomas Brown, elaborated on Cumberland’s (and Malebranche’s, as well as Leibniz’s) strategy for finding a third way between intellectualist view and voluntarist view of the laws of nature. The result of their elaboration was a kind of a rational-choice account of the origins of natural laws, where a law-giver God chooses among a number possible sets of laws on a maximizing criterion, and God’s maximandum is happiness for his creatures. The chapter notices also how such a solution aimed at solving at once the problem of evil and that of the foundation of moral obligation by proving how God’s choice was justified as far as it was the one minimising the amount of suffering in the world. 16. Richard Price and intuitionism. The chapter describes first the doctrines of the Cambridge Platonists, an example of hyper-rationalist reaction to Calvinism. Secondly it describes the sophisticated and universally ignored – from Sidgwick to Anscombe –version of what was later labelled ‘ethical intuitionism’ – showing how it escapes familiar objections and misrepresentations of intuitionism – from Mill to Rawls – in grounding its argument on transcendental arguments while carefully avoiding recourse to introspection and psychological evidence, which has been taken as a too easy target by critics of intuitionism. Thirdly, the chapter discusses Whewell’s ‘philosophy of morality’, as opposed to ‘systematic morality’, not unlike Kant’s distinction between a pure and an empirical moral philosophy. Whewell worked out a systematization of traditional normative ethics as a first step before its rational justification; he believed that the point in the philosophy of morality is justifying a few rational truths about the structure of morality such as to rule hedonism, eudemonism, and consequentialism; yet a system of positive morality cannot be derived solely from such rational truths but requires consideration of the ongoing dialectics between idea and fact in historically given moralities. Whewell’s intuitionism turns out closer to Kantian ethics than commentators have made us believe until now, and quite different from what Sidgwick meant by intuitionism. -/- 17. Adam Smith and the morality of role-switch. The chapter describes first, Hutcheson’s attempt at basing the ‘new science’ of natural law on different bedrock than Pufendorf and the English Platonists, namely a moral sense, a faculty whose existence is assumed to be proved on an empirical basis. The second step is a reconstruction of Hume’s rejoinder in terms of a new science of man including morality on an ‘experimental’ basis, that is, a ‘Newtonian’ hypothetical-deductive approach, distinguished from Hutcheson’s allegedly uncritical descriptive approach to human nature. The third step is a reconstruction of Adam Smith theory of morality understood as emerging from a spontaneous interplay of exchanges of situations (the most basic meaning of the word ‘sympathy’ as construed by this author). -/- 18. Jeremy Bentham and utilitarianism. The bulk of the chapter is dedicated to the doctrines of Jeremy Bentham. The Enlightenment spirit that suggested the idea of a new morality, free from religion, is illustrated. The notion of utility is illustrated as well as the subsequent formulations of the principle of utility. The idea of felicific calculus is discussed, showing how its inner difficulties prompted several reformulations of the principle of utility in order to avoid undesirable implications of proposed formulations. The role of the thesis of spontaneous convergence between interest and duty is discussed, showing how it left numberless questions open, and the distinction between the virtues of prudence, justice and beneficence is described as a way out of the deadlocks of classical utilitarianism. After Bentham, Mill’s reformed utilitarianism is reconstructed, showing how it is a kind of mixed system – as closer to common sense as it gives up Bentham’s claims to consistency and simplicity – resulting as unintended consequences from the controversies in which Mill was too keen to engage. The hidden agenda of the controversy between Utilitarianism and Intuitionism, going beyond the image of the battle between Prejudice and Reason, is described, showing how both competing philosophical outlooks turn out to be more research programs than self-contained doctrinal bodies, and such programs appear to be implemented, and indeed radically transformed while in progress thanks to their enemies no less than to their supporters. -/- 19. Immanuel Kant, practical reason and judgment. The chapter argues that Kant took from Moses Mendelssohn the idea of a distinction between geometry of morals and a practical ethic. He was drastically misunderstood by his followers precisely on this point. He had learned from the sceptics and the Jansenists the lesson that men are prompted to act by deceptive ends, and he was aware that human actions are also empirical phenomena, where laws like the laws of Nature may be detected. His practical ethics made room for judgment as a holistic procedure for assessing the saliency of relevant moral qualities in one given situation; this procedure yields the same results as the geometry of morals does for abstract cases but does so immediately and without balancing conflicting duties with each other, since what makes for the salient quality of a situation is perceived from the very beginning. Kant's practical philosophy is richer than the received image, making room for an ‘empirical moral philosophy’ or moral anthropology including treatment of commerce, needs, value and price, happiness and well-being; the overall social theory and philosophy of history is less different from Adam Smith's than the received image makes believe; the paradox of happiness is central to Kant's philosophy; a distinction between happiness and well-being is clearly drawn; the distinction plays a basic role in establishing a link between the economic and the moral life. -/- 20. Georg Wilhelm Friedrich Hegel and the critique of abstract universalism. The chapter describes first the Romantic movement and the implications some of its concerns, rescuing passions, community, tradition, the individual as the bearer of a unique destiny, and the longing for organic unity between the individual, mankind and nature. Hegel’s contribution is discussed then, highlighting how, on the one hand, he shared a number of these concerns and on the other he had more rationalist leanings. The notion of morality is the pivotal point of the reconstruction, highlighting how Hegel construes this notion as a key to his own diagnosis of the malaise of modernity – the separation of individual and Gemeinschaft – and how his attack on Kant turns around this very idea. -/- 21. Friedrich Nietzsche against Christianity and the Enlightenment. The chapter illustrates first the idea of deconstruction of the back-world of values. Nietzsche claims to be legitimate heir of the French moralists, Leibniz, Kant and Hegel, in so far as he allegedly carries out to its deepest implications their discovery of what lies behind traditional naïve belief in the existence of an objective realm of values just waiting for description by the philosopher. The two exemplars form which genealogy draws inspiration are the classical philologist’s historical reconstructions of lost meanings and the chemist’s decomposition of elements. Then the genealogy of the notions of good and evil carried out in the first dissertation of Genealogy of morals is illustrated with its paradoxical conclusion that will to power is in fact the only ‘genuine’ kind of goodness. The third point illustrated is the dialectic of ascetism and self-realization with its ambiguous outcome. The suggested interpretation of such outcome is that Nietzsche’s normative ethics is a kind of virtue ethics taking an aesthetic ideal as a normative standard -/- 22. George Edward Moore and ideal utilitarianism. The chapter discusses the ideas of common sense and common-sense morality in Sidgwick. I argue that, far from aiming at overcoming common-sense morality, Sidgwick aimed purposely at grounding a consist code of morality by methods allegedly taken from the natural sciences to reach, also in ethics, the same kind of “mature” knowledge as in the natural sciences. His whole polemics with intuitionism was vitiated by the a priori assumption that the widespread ethos of the educated part of humankind, not the theories of the intuitionist philosophers, was what was worth considering as the expression of intuitionist ethics. In spite of a naïve positivist starting-point, Sidgwick was encouraged by his own approach in exploring the fruitfulness of coherentist methods for normative ethics. Thus, Sidgwick left an ambivalent legacy to twentieth-century ethics: the dogmatic idea of a “new” morality of a consequentialist kind, and the fruitful idea that we can argue rationally in normative ethics albeit without shared foundations. Then it reconstructs the background of ideas, concerns and intentions out of which Moore’s early essays, the preliminary version, and then the final version of Principia Ethica originated. I stress the role of religious concerns, as well as that of the Idealist legacy. I argue that PE is more a patchwork of rather diverging contributions than a unitary work, not to say the paradigm of a new school in Ethics. I add a comparison with Rashdall’s almost contemporary ethical work, suggesting that the latter defends the same general claims in a different way, one that manages to pave decisive objections in a more plausible way. I end by suggesting that the emergence of Analytic Ethics was a more ambiguous phenomenon than the received view would make us believe, and that the wheat (or some other gluten-free grain) of this tradition, that is, what logic can do for philosophy, should be separated from the chaff, that is, the confused and mutually incompatible legacies of Utilitarianism and Idealism. -/- 23. Edmund Husserl and the a-priori of action. The chapter illustrates first the idea of phenomenology and the Husserl’s project of a phenomenological ethic as illustrated in his 1908-1914 lectures. The key idea is dismissing psychology and trying to ground a new science of the a priori of action, within which a more restricted field of inquiry will be the science of right actions. Then the chapter illustrates the criticism of modern moral philosophy carried out in the 1920 lectures, where the main target is naturalism, understood in the Kantian meaning of primacy of common sense. The third point illustrate is Adolph Reinach’s theory of social acts as a key the grounding of norms, a view that basically sketches the very ideas ‘discovered’ later by Clarence I. Lewis, John Searle, Karl-Otto Apel and Jürgen Habermas. A final section is dedicated to Nicolai Hartman, who always refused to define himself a phenomenologist and yet developed a more articulated and detailed theory of ‘values’ – with surprising affinities with George E. Moore - than philosophers such as Max Scheler who claimed to Husserl’s legitimate heirs. -/- 24. Bertrand Russell and non-cognitivism. The chapter reconstructs first the discussion after Moore. The naturalistic-fallacy argument was widely accepted but twisted to prove instead that the intuitive character of the definition of ‘good’, its non-cognitive meaning, in a first phase identified with ‘emotive’ meaning. Alfred Julius Ayer is indicated as a typical proponent of such non-cognitivist meta-ethics. More detailed discussion is dedicated to Bertrand Russell’s ethics, a more nuanced and sophisticated doctrine, arguing that non-cognitivism does not condemn morality to arbitrariness and that the project of a rational normative ethics is still possible, heading finally to the justification of a kind of non-hedonist utilitarianism. Stevenson’s theory, another moderate version of emotivism is discussed at some length, showing how the author comes close to the discovery of the role of a pragmatic dimension of language as a basis for ethical argument. Last of all, the discussion from the Forties about Hume’s law is described, mentioning Karl Popper’s argument and Richard Hare’s early non-cognitivist but non-emotivist doctrine named prescriptivism. -/- 25. Elizabeth Anscombe and the revival of virtue ethics. The chapter discusses the three theses defended by Anscombe in 'Modern Moral Philosophy'. I argue that: a) her answer to the question "why should I be moral?" requires a solution of the problem of theodicy, and ignores any attempts to save the moral point of view without recourse to divine retribution; b) her notion of divine law is an odd one more neo-Augustinian than Biblical or Scholastic; c) her image of Kantian ethics and intuitionism is the impoverished image manufactured by consequentialist opponents for polemical purposes and that she seems strangely accept it; d) the difficulty of identifying the "relevant descriptions" of acts is not an argument in favour of an ethics of virtue and against consequentialism or Kantian ethics, and indeed the role of judgment in the latter is a response to the difficulties raised by the case of judgment concerning future action. A short look at further developments in the neo-naturalist current is given trough a reconstruction of Philippa Foot’s and Peter Geach’s critiques to the naturalist-fallacy argument and Alasdair MacIntyre’s grand reconstruction of the origins and allegedly unavoidable failure of the Enlightenment project of an autonomous ethic. -/- 26. Richard Hare and neo-Utilitarianism. The chapter addresses the issue of the complex process of self-transformation Utilitarianism underwent after Sidgwick’s and Moore’s fatal criticism and the unexpected Phoenix-like process of rebirth of a doctrine definitely refuted. A glimpse at this uproarious process is given through two examples. The first is Roy Harrod Wittgensteinian transformation of Utilitarianism in pure normative ethics depurated from hedonism as well as from whatsoever theory of the good. This results in preference utilitarianism combined with a ‘Kantian’ version of rule utilitarianism. The second is Richard Hare’s two-level preference utilitarianism where act utilitarianism plays the function of eventual rational justification of moral judgments and rule-utilitarianism that of action-guiding practical device. -/- 27. Hans-Georg Gadamer and rehabilitation of practical philosophy. The post-war rediscovery of ethics by many German thinkers and its culmination in the Sixties in the movement named ‘Rehabilitation of practical philosophy’ is described. Among the actors of such rehabilitation there were a few of Heidegger’s most brilliant disciples, and Hans-Georg Gadamer is chosen as a paradigmatic example. His reading of Aristotle’s lesson I reconstructed, starting with Heidegger’s lesson but then subtly subverting its outcome thanks to the recovery of the central role of the notion of phronesis. -/- 28. Karl-Otto Apel and the revival of Kantian ethics. Parallel to the neo-Aristotelian trend, there was in the Rehabilitation of practical philosophy a Kantian current. This started, instead than the rehabilitation of prudence, with the discovery of the pragmatic dimension of language carried out by Charles Peirce and the Oxford linguistic philosophy. On this basis, Karl-Otto Apel singled out as the decisive proponent of the linguistic and Kantian turn in German-speaking ethics, worked out the performative-contradiction argument while claiming that this was able to provide a new rational and universal basis for normative ethics. An examination of his argument is some detail is offered, followed by a more cursory reconstruction of Jürgen Habermas’s elaboration on Apel’s theory. -/- 29. John Rawls and public ethics as applied ethics. Rawls’s distinction between a “political” and a “metaphysical” approach to one central part of ethical theory, namely the theory of justice, is interpreted as a formulation of the same basic idea at the root of both the principles approach and neo-casuistry, both discussed in the following chapter, namely that it is possible to reach an agreement concerning positive moral judgments even though the discussion is still open – and in Rawls’ view never will be close – on the basic criteria for judgment. -/- 30. Beauchamp and Childress and bioethics as applied ethics. The chapter presents the revolution of applied ethics while stressing its methodological novelty, exemplified primarily by Beauchamp and Childress principles approach and then by Jonsen and Toulmin’s new casuistry. -/- .

I report two experiments studying the relationship among explicit judgments about what people see, know, and should assert. When an object of interest was surrounded by visibly similar items, it diminished people’s willingness to judge that an agent sees, knows, and should tell others that it is present. This supports the claim, made by many philosophers, that inhabiting a misleading environment intuitively decreases our willingness to attribute perception and knowledge. However, contrary to stronger claims made by some philosophers, inhabiting a (...) misleading environment does not lead to the opposite pattern whereby people deny perception and knowledge. Causal modeling suggests a specific psychological model of how explicit judgments about perception, knowledge, and assertability are made: knowledge attributions cause perception attributions, which in turn cause assertability attributions. These findings advance understanding of how these three important judgments are made, provide new evidence that knowledge is the norm of assertion, and highlight some important subtleties in folk epistemology.

I argue that the notion of reflective epistemic luck raises important questions about the centrality to epistemology of a conception of justification that demands that one is able to take cognitive responsibility for one’s beliefs. I take a critical look at some of the recent ‘virtue epistemologies’ that have been put forward in the recent literature which define knowledge in terms of the epistemic virtues and cognitive faculties. More specifically, I contrast broadly externalist construals of the virtue-theoretic thesis—such as (...) the ‘agent reliabilism’ advanced, for example, by Ernest Sosa and John Greco—with virtue epistemologies that roughly fall into the internalist camp—in particular, ‘neo-Aristotelian’ theories, such as the view defended by Linda Zagzebski. I claim that in each case a key part of the motivation for offering such a view lies in a desire to eliminate a species of epistemic luck that is thought to be left uneliminated by rival theories of knowledge. In general, I claim that externalists and internalists in epistemology often speak past one another precisely because they are concerned with these different types of epistemic luck, and that disambiguating the species of epistemic luck at issue in this debate can help us to find a way of reconciling both internalist and externalist intuitions about knowledge. I conclude by arguing that once the ambiguous role of epistemic luck in the development of these virtue epistemological theories is made explicit, then the motivation to offer a specifically virtue-theoretic theory of knowledge subsides.

The safety condition on knowledge, in the spirit of anti-luck epistemology, has become one of the most popular approaches to the Gettier problem. In the first part of this essay, I intend to show one of the reasons the anti-luck epistemologist presents for thinking that the safety theory, and not the sensitivity theory, offers the proper anti-luck condition on knowledge. In the second part of this essay, I intend to show that the anti-luck epistemologist does not (...) succeed, because the safety theory fails to capture a necessary requirement for the possession of knowledge. I will attack safety on two fronts. First, I will raise doubts about whether there is any principled safety condition capable of handling a kind of case, involving inductive knowledge, that it was designed to handle. Second, I will consider two cases in which the safety condition is not met but the protagonist seems to have knowledge nonetheless, and I will vindicate my intuitions for thinking that those are in fact cases of knowledge by contrasting them with traditional, well-known Gettier cases. I want to conclude, finally, that safety failures do not necessarily prevent one from acquiring knowledge. (shrink)

In the early 1990s there emerged a growing interest with the concept of epistemic entitlement. Philosophers who acknowledge the existence of entitlements maintain that there are beliefs or judgments unsupported by evidence available to the subject, but which the subject nonetheless has the epistemic right to hold. Some of these may include beliefs non-inferentially sourced in perception, memory, introspection, testimony, and the a priori. Unlike the traditional notion of justification, entitlement is often characterized as an externalist type of epistemic warrant, (...) in the sense that a subject’s being entitled is determined by facts and circumstances that are independent of any reasoning capacities she may or may not have, and which the subject herself need not understand or be able to recognize. One key motivation for this view is that the inclusion of entitlement in epistemology can account for the commonly held intuition that largely unreflective individuals, such as children and non-human animals, possess warrant and basic knowledge about the world. It also paves the way for a tenable foundationalist epistemology, according to which there exist warranted beliefs which are not themselves warranted or justified by any further beliefs. This article explores theories of entitlement as presented by four prominent philosophers: Fred Dretske, Tyler Burge, Crispin Wright, and Christopher Peacocke. (shrink)

Epistemological Disjunctivism is a view about paradigm cases of perceptual knowledge. Duncan Pritchard claims that it is particularly well suited to accounting for internalist and externalist intuitions. A number of authors have disputed this claim, arguing that there are problems for Pritchard’s way with internalist intuitions. I share the worry. However, I don’t think it has been expressed as effectively as it can be. My aim in this paper is to present a new way of formulating the worry, in terms (...) of an “explanatory challenge”. The explanatory challenge is a simple, yet powerful and illuminating challenge for Epistemological Disjunctivism. It is illuminating in the sense that it shows us why Epistemological Disjunctivism must take on certain internalistically problematic commitments. A secondary aim of this paper is to examine whether the recently much-discussed distinction between justifications and excuses in epistemology can support an adequate response. I will argue that it cannot. (shrink)

Justification, or at least ‘justification’, bulks large in recent epistemology. The view that knowledge consists of true-justified-belief has been prominent in this century, and the justification of belief has attracted considerable attention in its own right. But it is usually not at all clear just what an epistemologist means by ‘justified’, just what concept the term is used to express. An enormous amount of energy has gone into the attempt to specify conditions under which beliefs of one or another sort (...) are justified; but relatively little has been done to explain what it is for a belief to be justified, what that is for which conditions are being sought. The most common procedure has been to proceed on the basis of a number of obvious cases of justified belief, without pausing to determine what property it is of which these cases are instances. Now even if there were some single determinate concept that all these theoriests have implicitly in mind, this procedure would be less than wholly satisfactory. For in the absence of an explicit account of the concept being applied, we lack the most fundamental basis for deciding between supposed intuitions and for evaluating proposed conditions of justification. And in any event, as philosophers we do not seek merely to speak the truth, but also to gain an explicit, reflective understanding of the matters with which we deal. We want to know not only when our beliefs are justified, but also what it is to enjoy that status. True, not every fundamental concept can be explicated, but we shall find that much can be done with this one. (shrink)

Experimental restrictionists have challenged philosophers’ reliance on intuitions about thought experiment cases based on experimental findings. According to the expertise defense, only the intuitions of philosophical experts count—yet the bulk of experimental philosophy consists in studies with lay people. In this paper, we argue that direct strategies for assessing the expertise defense are preferable to indirect strategies. A direct argument in support of the expertise defense would have to show: first, that there is a significant difference between expert and lay (...) intuitions; second, that expert intuitions are superior to lay intuitions; and third, that expert intuitions accord with the relevant philosophical consensus. At present, there is only little experimental evidence that bears on these issues. To advance the debate, we conducted two new experiments on intuitions about knowledge with experts and lay people. Our results suggest that the intuitions of epistemological experts are superior in some respects, but they also pose an unexpected challenge to the expertise defense. Most strikingly, we found that even epistemological experts tend to ascribe knowledge in fake-barn-style cases. This suggests that philosophy, as a discipline, might fail to adequately map the intuitions of its expert practitioners onto a disciplinary consensus. (shrink)

According to anti-luck approaches to the analysis of knowledge, knowledge is analyzed as unlucky true belief, or unlucky justified true belief. According to virtue epistemology, on the other hand, knowledge is true belief which a subject has acquired or maintained because of the exercise of a relevant cognitive ability. ALE and VE both appear to have difficulty handling some intuitive cases where subjects have or lack knowledge, so Pritchard proposed that we should take an anti-luck condition and a (...) success-from-ability condition as independent necessary conditions on knowledge. Recently, Carter and Peterson have argued that Pritchard’s modal notion of luck needs to be broadened. My aim in this paper is to show that, with the modal conception of luck appropriately broadened, it is no longer clear that ALE needs to be supplemented with an independent ability condition in order to handle the problematic Gettier cases.

An orthodox view in epistemology holds that propositional knowledge is an absolute ‘yes or no’ affair, viz, propositional knowledge is ungradable. Call this view epistemic absolutism. This thesis purports to challenge this absolutist orthodoxy and develop an underexplored position—epistemic gradualism, which was initially proposed by Stephen Hetherington. As opposed to epistemic absolutism, epistemic gradualism argues that propositional knowledge can come in degrees. This thesis will examine motivations for endorsing absolutism and then, drawing on Hetherington’s original objections to absolutism, prove that (...) absolutism is ill-grounded. In particular, I will explain why the primary ground for insisting absolutism, to wit, linguistic evidence from ordinary English language, fails to entail that knowledge-that is an ungradable concept. After that, I will revisit Hetherington’s two versions of gradualist theories—both will be revealed to be defective. Moreover, the current model of the debate between absolutism and gradualism constructed by Hetherington will give rise to an equivocal attitude towards the gradability of knowledge. That is, there is a prevailing equivocal view which agrees that knowledge can be improved by virtue of better justification but denies that knowledge is, by and large, a gradable concept. This thesis proposes to remodel the debate between absolutism and gradualism by basing it on a dispute about whether knowledge has a cut-off point distinguishing knowledge from everything that falls short of knowledge. Succinctly put, whether propositional knowledge has a threshold. It will be argued that gradualism, so interpreted, should deny that knowledge has a threshold, and treat knowledge as a spectrum concept analogous to ‘red’, ‘warm’, and so forth. The theoretical merits of this new model of the debate and the reconstructed gradualism will be shown. With a better-constructed gradualist account of knowledge in play, I will demonstrate how gradualism enjoys advantages over absolutism by illustrating gradualism’s potential applications in solving epistemological issues that absolutism finds difficult to address. For example, issues related to epistemic luck, faultless disagreements, scepticism, and the relationship between different types of knowledge. (shrink)

The book has two parts: one metaphysical, the other epistemological. The metaphysical part is largely concerned with realism issues. It starts with realism about universals, dismissing Plato's notorious ‘one over many’ problem. Several chapters argue for a fairly uncompromisingly realist view of the external physical world of commonsense and science. Both the nonfactualism of moral noncognitivism and positivistic instrumentalism, and deflationism about truth, are found to rest on antirealisms about their subject matters that are hard to characterize. A case is (...) presented for moral realism. Various biological realisms are considered. Finally, an argument is presented for an unfashionable biological essentialism. The epistemological part of the book argues against the a priori and for a Quinean naturalism. The intuitions that so dominate ‘armchair philosophy’ are empirical not a priori. There is an emphasis throughout the book on distinguishing metaphysical issues about what there is and what it's like from semantic issues about meaning, truth, and reference. Another central theme, captured in the title, is that we should ‘put metaphysics first’. We should approach epistemology and semantics from a metaphysical perspective rather than vice versa. The epistemological turn in modern philosophy and the linguistic turn in contemporary philosophy were something of disasters. (shrink)

Rational intuitions involve a particular form of understanding that gives them a special epistemic status. This form of understanding and its epistemic efficacy are not explained by several current theories of rational intuition, including Phenomenal Conservatism (Huemer, Skepticism and the veil of perception, 2001 ; Ethical intuitionism, 2005 ; Philos Phenomenol Res 74:30–55, 2007 ), Proper Functionalism (Plantinga, Warrant and proper function, 1993 ), the Competency Theory (Bealer Pac Philos Q 81:1–30, 2000 ; Sosa, A virtue epistemology, 2007 ) and (...) the Direct Awareness View (Conee, Philos Phenomenol Res 4:847–857, 1998 ; Bonjour, In defense of pure reason, 1998 ). Some overlook it; others try to account for it but fail. We can account for the role of understanding in rational intuition by returning to the view of some of the early Rationalists, e.g. Descartes and Leibniz. While that view carries a prohibitive cost, it does contain an insight that may help us solve the problem of giving understanding its due. (shrink)
