This article is primarily a defense of the Paradigm Case Argument (PCA). It is secondarily a comment on a recent controversy over the validity of its use in philosophy. I argue that the controversy rests on a misinterpretation. By extending the analysis of the objections (and here I invoke Descartes' famous method of possible doubt) I show that the occurrence of a paradigm and the fact that a concept is normally used to describe that paradigm logically entails not (...) that the paradigm is instantiated, but only that it is correct to apply that concept to that paradigm. In this manner the ontological fallacy is avoided, and further, this enforces the important separation between saying something about the correct application of a concept and saying something about its meaning.

Any criticism that can be made of philosophy necessarily implies knowledge of the nature of its symbolic structures. Accordingly, in this paper, I argue that the reflective value of philosophy in the understanding of reality must start by taking into account the peculiar features of the symbolic elements, which compose and support its epistemic structures. The representative core of these elements is, to that extent, the philosophical concept. Through it, as I will try to bring to light, the human mind (...) acquires an ideal coupling between thought objects and the act of thinking itself, which in turn differs from that of other forms of knowledge. The question remains, however, whether such unity always carries a sense of reality and what its nature is. (shrink)

A prominent contemporary anti-skeptical strategy, most famously articulated by Keith DeRose, aims to cage the skeptic′s doubts by contextualizing subjunctive conditional accounts of knowledge through a conversational rule of sensitivity. This strategy, I argue, courts charges of circularity by selectively invoking heavy counterfactual machinery. The reason: such invocation threatens to utilize a metric for modal comparison that is implicitly informed by judgments of epistemic sameness. This gives us reason to fear that said modal metric is selectively cherry-picked in advance to (...) support the very anti-skeptical conclusion for which the contextualist longs. (shrink)

Kripke has noted that possible worlds are stipulated, not discovered, and that the stipulation of these worlds allows us to separate accidental from essential properties. In this paper I argue that possible worlds theory gives us an important tool for analyzing what Descartes is doing in the Meditations. The first Meditation becomes a thought experiment in which possible realities are stipulated in a search for one or more essential properties. Viewing the doubt in this manner sheds (...) new light on the cogito and sum res cogitans and shows the limitations of some contemporary discussion of the cogito, namely, the positions taken by Ayer and Hintikka.

‘The doubtful story of successive events’. With these words Bernard Bosanquet is often taken to have damned historical knowledge to oblivion. Although it is undeniably true that Bosanquet uttered these words and saw them into print, it is much less clear what he intended their import to be and whether he intended to damn history as a form of knowledge as such. Although he wrote little directly which can be construed as ‘philosophy of history’, he developed views both implicitly and (...) explicitly which bear on this question. My concern in this paper is to show that Bosanquet’s animosity to history derived not from a desire to condemn, but from a desire to draw more from history than the historiography of his time would, in good philosophical conscience, allow him to. His words were words of disappointment and despair, of thwarted hope, rather than outright rejection. I shall argue that Bosanquet needed an account of historical experience to flesh out his account of the concrete universal. A re-telling of the story of Bosanquet and history shows how, if it had been possible for him to draw together unresolved strands in his thinking, he could have affirmed historical experience as ‘the heart beat of the absolute’. Following Foster I shall claim that he was ultimately committed to this, but was reluctant or unable to draw it out explicitly from his leading doctrines. (shrink)

Introduction There is faith in every serious doubt ... he who seriously denies God, affirms him . . . there is no possible atheism. ...

A longstanding question is the extent to which "reasonable doubt" may be expressed simply in terms of a threshold degree of belief. In this context, we examine the extent to which learning about possible alternatives may alter one's beliefs about a target hypothesis, even when no new "evidence" linking them to the hypothesis is acquired. Imagine the following scenario: a crime has been committed and Alice, the police's main suspect has been brought to trial. There are several pieces (...) of evidence that raise the probability that Alice committed the crime. Her attorney's defense strategy is not to challenge this evidence, but instead to provide personal details about Alice's neighbour, Jane. While Jane is one of many people the police spoke to, they saw no reason to investigate her further. You now learn that Jane, too, had access to the shed where the murder weapon was stored, just like Alice. To what extent should this alter your beliefs about Alice's guilt? In this paper, we provide a formal description of the problem and a solution indicating circumstances under which learning about Jane will more or less impact beliefs about Alice. (shrink)

In this article I examine the role of anxiety in our motivation to reassess our epistemic states, by taking as a starting point a proposal put forward by Levy, according to which anxiety is responsible for the ruminations and worries about threatening possibilities that we sometimes get caught up into in our everyday life. Levy’s claim is that these irrational persistent thoughts about possible states of affairs are best explained by anxiety, rather than by beliefs, degrees of belief, or (...) other mental states. I will take Levy’s article as a starting point into my study of the role of anxiety in our inclinations to question the epistemic quality of our cognitive states. While I believe that Levy is right in directing our attention to the role of anxiety in these cases, his claim calls for further explanation into the nature of anxiety, and into the mechanisms through which anxiety generates these doubts. Although the relation between anxiety and doubt has already been highlighted, there has been little effort to elaborate on the mechanisms through which an affective state like anxiety generates a motivation to reassess our beliefs. This paper is an attempt at providing such an elaboration. Clarifying the role of anxiety in these phenomena will lead me to revise a common assumption about the interactions between anxiety and higher-level cognitive processes, such as the ones involved in representing hypothetical threatening scenarios through mental imagery.

In On Certainty, Ludwig Wittgenstein puts forth a unique defense against skepticism. According to Wittgenstein, “we just can’t investigate everything, and for that reason we are forced to rest content with assumption. If I want the door to turn, the hinges must stay put.” These hinges provide the necessary framework for epistemic evaluation. The question is how to understand Wittgenstein’s language here. Duncan Pritchard puts forward a non-belief reading whereby one has a non-belief propositional attitude towards hinge propositions. In this (...) paper, I explain Pritchard’s reading of Wittgenstein before attacking it with an argument premised upon our ability to doubt hinge propositions. If we can doubt hinge propositions, then, according to a view of doubt defended by Andrew Moon, we can believe that ~ p is possible. And, if we can believe that ~ p is possible, then we can believe that p. I walk through a defense of each premise in this argument, which shows that Pritchard’s reading fails. I conclude by responding to some potential objections, which allow us to distinguish between two types of doubt: rational and psychological. (shrink)

Many philosophers now argue that the doubts of the philosophical sceptic are unnatural ones, in that they are not forced on us by considerations that any reasonable person would have to accept as compelling but only arise if one has already accepted certain controversial theoretical commitments. In this article I defend the naturalness of philosophical scepticism against such criticisms. After defining "global ontological scepticism," I examine the work of a number of anti-sceptical philosophers—Michael Huemer, Michael Williams, and John McDowell. Although (...) McDowell does move the debate to a deeper level by interpreting scepticism as a challenge to the very possibility of the mind's apprehending reality by being in a rational rather than a merely causal relation to it, none of them succeeds in showing that global ontological scepticism is, in the relevant sense, unnatural. This is not to say that the sceptic is correct; simply that it has not been shown that we can reasonably dismiss the sceptical questions and thereby evade the need to engage seriously with the sceptical arguments.

Supported by Ian Hacking’s concept of “intervention,” and Charles Taylor’s concept of “intentionality,” this article argues that doubting is acting, and that doubting is therefore subject to the same demands of responsibility as any other action. The argument is developed by using medical practice as a test-case. The central suggestion is that the demand of acting responsibly limits doubt in medicine. The article focuses on two such limitations to doubt. Firstly, the article argues that it is irresponsible to (...) doubt that our actions can harm other people. Secondly, the article argues that it is irresponsible not to strive for coherence between our utterances of doubt and our other actions. Incoherence here can cause “cultural impoverishment.” In a larger context this article also argues that medicine can enrich our epistemology, because medical knowledge displays important traits of knowledge that are downplayed in traditional epistemology derived from mathematics and physics. In particular, medicine makes it possible to get the relation between ethics and epistemology into sharper focus. The endpoint in medical epistemology is “responsible action,” and not certainty in and of itself. (shrink)

In this paper, I present and defend a novel account of doubt. In Part 1, I make some preliminary observations about the nature of doubt. In Part 2, I introduce a new puzzle about the relationship between three psychological states: doubt, belief, and confidence. I present this puzzle because my account of doubt emerges as a possible solution to it. Lastly, in Part 3, I elaborate on and defend my account of doubt. Roughly, one (...) has doubt if and only if one believes one might be wrong; I argue that this is superior to the account that says that one has doubt if and only if one has less than the highest degree of confidence.

In “On Certainty” Wittgenstein regards doubting as meaningful and reasonable only in a context providing language game where some background is taken for granted. Doubt, just as knowledge, should be backed up by an argument, only this time, one presenting reasons for uncertainty. Common sense propositions constitute part of the background for the arguments of doubting and because of their function and place within the system of language, they are regarded as indubitable. I discuss critically the idea of linguistically (...) determined indubitability and advocate the possibility of a different kind of doubt, one that does not require its own justification and is still a reasonable epistemic attitude. Such doubt characterizes the states of affairs where the certainty of a proposition is not yet rationally established. I argue that, language does not limit us in doubting and in doubting reasonably.

This article explicates the notion of doubt and the relationship of doubt to belief and conviction. It distinguishes three types of political virtue—leadership, systemic, and corrective—and considers whether doubt is a political virtue in any of these three senses. It is argued that while doubt is not a leadership virtue, it is a systemic and a corrective virtue. Specifically, it is potentially an antidote to methods, ideological, and psychological extremism. A distinction is drawn between extremism and (...) forms of radicalism that have resulted in social progress. It is possible for doubt to play a role in countering extremism without thereby also countering progressive radicalism. The concluding section develops a theory of deradicalization and identifies the role of radical doubt in deradicalization programmes. The proposed empirically informed account of deradicalization highlights the role of narratives in radicalization and deradicalization. (shrink)

Danièle Moyal-Sharrock and Constantine Sandis have suggested that our sense of being ‘women’ (and ‘men’) can be elucidated by thinking of it as an animal certainty. The suggestion is helpful in resisting the notion that ‘being woman’ can be modelled either on the idea of indubitable first-person knowledge of one’s inner self or of a third person’s unquestionable knowledge of one’s body. One’s being woman is manifested in one’s ways of acting and reacting; it constitutes a mode of being, which (...) cannot be given further justification. Nevertheless, I argue that the emphasis on certainty may render the possible doubts an individual may entertain about being a woman at different stages and in different contexts of their life opaque. It may also obscure the philosophical analysis of what thinking of certainty with Wittgenstein may offer to the understanding of ‘woman’, since for him the exploration of meaningful and impossible forms of doubt always ran parallel to his thinking on certainty. Considering everyday examples of certainty and doubts in being a woman, I therefore discuss the dialectic between certainty and doubt in the constitution of being ‘a woman’, giving special attention to the significance of second person assertions and comments for the first person’s experience of being or not being a woman or not being ‘woman enough’.

In criminal trials, judges or jurors have to decide whether the facts described in the indictment are proven beyond a reasonable doubt. However, these decision-makers cannot always imagine every relevant sequence of events—there may be unconceived alternatives. The possibility of unconceived alternatives is an overlooked source of reasonable doubt. I argue that decision-makers should not consider the defendant’s guilt proven if they have good reasons to believe that plausible, unconceived scenarios exist. I explore this thesis through the lens (...) of the two most influential accounts of rational criminal proof—Bayesian and explanation-based approaches. I draw on related ideas from the philosophy of science to show why and when unconceived alternatives lead to reasonable doubt on either account. (shrink)

In a 1955 lecture the physicist Richard Feynman reflected on the place of doubt within scientific practice. ‘Permit us to question, to doubt, to not be sure’, proposed Feynman, ‘it is possible to live and not to know’. In our contemporary world, the science of machine learning algorithms appears to transform the relations between science, knowledge and doubt, to make even the most doubtful event amenable to action. What might it mean to ‘leave room for (...) class='Hi'>doubt’ or ‘to live and not to know’ in our contemporary culture, where the algorithm plays a major role in the calculability of doubts? I propose a posthuman mode of doubt that decentres the liberal humanist subject. In the science of machine learning algorithms the doubts of human and technological beings nonetheless dwell together, opening onto a future that is never fully reduced to the single output signal, to the optimised target.

Kant’s conception of the relation between knowledge and doubt stands opposed to much of contemporary epistemology. For Kant denies that it is possible for one to have knowledge of how things are without having a ground for one’s judgment that guarantees its truth. Knowledge, according to him, is judgment that is based on a ground that the judger recognizes to guarantee the truth of her judgment. A judgment that is based on such a ground, trivially, excludes any (...) class='Hi'>doubt the judger might have had with respect to it. Therefore knowledge implies certainty. Much of contemporary epistemology has no room for the idea of a truth-guaranteeing ground. By contrast, Kant thinks that the rejection of the idea of a truth-guaranteeing ground has a devastating effect. It does not only render unintelligible the idea of knowledge, but, because of that, the very idea of a subject that is able to be ignorant about things, to have doubts about them or even to err about them. The paper defends the Kantian account of knowledge with the aim to show that ignorance, doubt and error can only characterize, and hence trouble, a subject that knows herself to have a capacity that enables her to overcome any possible doubt and error.

The myth of transparency and truthfulness is the foundation for contemporary theories of information design. Avoiding distortion and ambiguity is the moral imperative of an upstanding data visualizer. Sometimes, though, data that is collected is not accurate enough and the sources use indirect indicators to approach a phenomenon: what to do then, if the need to graphically represent a phenomenon is urgent and necessary? Should the designer wait to have the exact data, or should he indicate a trend, expressing the (...) hypothetical status of his statement? Can data visualization be designed to express doubt rather than to inform about facts? This essay will deal with the forms of expression of uncertainty in infographics. It will consider the designer as both an observer and a translator, whose position of neutrality is only one of the possible realms of discourse. In general, it will focus on the forms of visual expression of a self-criticizing mood in quantitative research today and it will explore the ways in which data that is not meaningful in statistical terms can become meaningful in semiotic terms.

Ernest Sosa's virtue perspectivism can be thought of as an attempt to capture as much as possible of the Cartesian project in epistemology while remaining within the framework of externalist fallibilism. I argue (a) that Descartes's project was motivated by a desire for intellectual stability and (b) that his project does not suffer from epistemic circularity. By contrast, Sosa's epistemology does entail epistemic circularity and, for this reason, proves unable to secure the sort of intellectual stability Descartes wanted. I (...) then argue that this leaves Sosa's epistemology vulnerable to an important kind of skepticism. (shrink)

Since Descartes, the nature of doubt has played a central role in the development of metaphysics both positively and negatively. Despite this fact, there has been very little discussion centering round the specific nature of doubt which led, for example, to the Cartesian discovery of the cogito. Certainly, the role of doubt has been well recognized: through doubt Descartes arrives at his indubitable first principle. But what can it mean to doubt the existence of the (...) sensible world? This would seem to rest upon the assumption that we have clear and distinct knowledge of the precise nature of what it means to exist and indeed of what it means to be. As it stands, Descartes’ initiates his Meditations upon certain definite assumptions that demand more thorough interrogation. In this paper and presentation, I examine the possible assumptions inherent in the Cartesian method of doubt within the first and second meditation and the manner in which this leads to the discovery of the cogito. I consider a number of essential questions in light of this: What presuppositions lie at bottom to Cartesian doubt? What is the precise nature of metaphysical doubt? What can it mean to doubt the existence of the sensible world? (shrink)

The question of what Descartes did and did not doubt in the Meditations has received a significant amount of scholarly attention in recent years. The process of doubt in Meditation I gives one the impression of a rather extreme form of skepticism, while the responses Descartes offers in the Objections and Replies make it clear that there is in fact a whole background of presuppositions that are never doubted, including many that are never even entertained as possible (...) candidates of doubt. This paper resolves the question of this undoubted background of rationality by taking seriously Descartes’ claim that he is carrying out demonstrations modeled after the great geometers. The rational order of geometrical demonstration demands that we first clear away previous demonstrations not proven with the certainty necessary for genuine science. This is accomplished by the method of doubt, which is only applied to the results of possible demonstrations. What cannot be doubted are the very concepts and principles employed in carrying out geometrical demonstration, which enable it to take place. It would be senseless to ask whether we can doubt the essential components of the structure through which questioning, doubting, and demonstration are made possible. (shrink)

How does doubt come about? What are the mechanisms responsible for our inclinations to reassess propositions and collect further evidence to support or reject them? In this paper, I approach this question by focusing on what might be considered a distorting mirror of unreasonable doubt, namely the pathological doubt of patients with obsessive–compulsive disorder (OCD). Individuals with OCD exhibit a form of persistent doubting, indecisiveness, and over-cautiousness at pathological levels (Rasmussen and Eisen in Psychiatr Clin 15(4):743–758, 1992; (...) Reed in Obsessional experience and compulsive behaviour: a cognitive-structural approach, Academic Press, Cambridge, 1985; Tolin et al. in Cogn Ther Res 27(6):657–669, 2003). I argue that the failure in OCD is of an affective nature, involving both excessive epistemic anxiety and hyperactive feelings of uncertainty. I further argue that our adaptive disposition to inquire about the right matters—that is, about propositions which are both epistemically risky and imply harmful possibilities—might depend on these affective mechanisms.

This essay distinguishes between propositional belief and faith and considers the relationship between these two forms of belief, arguing that faith is not an entirely separate form of belief from propositional assent and that it does require a minimal cognitive content. The essay then goes on to consider beliefs about, and faith in, life after death and develops a metaphorical account of this faith using an Aristotelian concept of the soul as a form of life together with a theological understanding (...) of the death of Jesus in the New Testament. It is argued that the truth claims of assertions about life after death are beyond evidential support, but there are strong reasons for doubting the literal truth of such assertions. Faith in life after death however can be considered rational and truth-seeking. The essay concludes that semantic agnosticism is the proper attitude towards belief in life after death and justifies this position against two possible objections. (shrink)

The use of evidence to resolve uncertainties is key to many endeavours, most conspicuously science and law. Despite this, the logic of uncertainty is seldom taught explicitly, and often seems misunderstood. Traditional educational practice even fails to encourage students to identify uncertainty when they express knowledge, though mark schemes that reward the identification of reliable and uncertain responses have long been shown to encourage more insightful understanding. In our information-rich society the ability to identify uncertainty is often more important than (...) the possession of knowledge itself. In both science and law there are fundamentally different kinds of uncertainty at issue. There is uncertainty whether a particular hypothesis is correct, and there is uncertainty about observable data that may be generated if a particular hypothesis is correct. Both are expressed in terms of probabilities. Each has its own domain of application and its own logic, but the inter-relationship is complex and sometimes misunderstood. Hypothesis probabilities are always open to error through possible failure to take account of realistic alternatives, while the proper inferences that can be drawn from data probabilities (often in the context of significance testing) are quite limited and easily over-interpreted. When considering these two kinds of probability in a court of law it is possible to interpret the phrase 'reasonable doubt' in different ways. It can be seen as addressing data uncertainty: whether such incriminating evidence might with reasonable probability arise to confront an innocent person. Or (the more conventional view) it can be seen as some sort of threshold level on the probability that the defendant is guilty (a hypothesis probability). Each typically involves elements of subjective judgement, but fewer issues and uncertainties arise when considering the data probability and it is argued that this is often the more critical and proper issue for a jury to address. This has particular repercussions for cases involving identification of a suspect through trawl of a DNA or other database. (shrink)

In this paper I respond to Gunter Zimmermann's article on doubt and faith in God that was published in this journal last year, by offering some criticisms of his views and elaborating on certain issues that Zimmermann leaves nearly or entirely untouched. First, I argue that Zimmermann's analysis of doxastic doubt is incomplete. Next, I defend the thesis that whether some specific doxastic doubt is compatible with someone's faith depends in at least four regards on the person (...) who has that doubt. Subsequently, I champion the view that some so-called fiducial doubts are compatible with faith in God, whereas certain others are not. Also, I explain why by its very nature having some fiducial doubt entails having some doxastic doubt. Finally, I deal with some biblical passages in order to show why they do not preclude the possibility of someone's having faith and at the same time having certain fiducial doubts. (shrink)

In examining Husserl's noesis–noema correlate, which characterizes his intentionality thesis of 1913, this article argues toward “presentation” as a sufficient mode of givenness in accounting for religious phenomena by demonstrating how an intentional analysis of faith and doubt is possible if one's regard is directed toward the noetic moment of believing and its corresponding noema: the “believed as believed.” This will be shown by directly engaging with the eidetic laws of Husserl's series of belief modalities.

Because of the many criticisms of the notion of a theory independent observation language, it is useful to look at a few actual examples of scientific data to see what theories might be implicit and in what way. There are several possibilities. The theories could be previously accepted, under active investigation, or of a kind that has never been systematically examined. The present study explores these possibilities in the data of several scientific journal articles. The conclusion is that theories and (...) regularities of all three kinds can be found as antecedent conditions of data statements. Any descriptive account of scientific inference must find room for such presuppositions. (shrink)

Excerpt from A Defence of Philosophic Doubt: Being an Essay on the Foundations of Belief What is meant by Ethics I have Shown at length in the Appendix which will be found at the end of the volume. Here it is only necessary to say that it includes, not only what are commonly called moral systems, but also some analogous systems not usually so described. Multitudes of propositions, all professing to em body knowledge belonging to one or other of (...) these departments, are being continually put forward for our acceptance. And as no one believes all of them, so those who profess to act rationally must hold that there are grounds for rejecting the propositions they disbelieve, and for accepting those they believe. The systematic account of. These grounds of belief and disbelief makes up the fourth of the Classes into which possible knowledge is divided, and is here always called Philosophy.

Descartes is well known for his employment of the method of doubt. His most famous work, the Meditations, begins by exhorting us to doubt all our opinions, including our belief in the existence of the external world. But critics have charged that this universal doubt is impossible for us to achieve because it runs counter to human nature. If this is so, Descartes must be either misguided or hypocritical in proposing it. Hume writes:There is a species of (...) scepticism, antecedent to all study and philosophy, which is much inculcated by Des Cartes and others, as a sovereign preservative against error and precipitate judgement. It recommends an universal doubt, not only of all our former opinions and principles, but also of our very faculties… The Cartesian doubt, …were it ever possible to be attained by any human creature would be entirely incurable; and no reasoning could ever bring us to a state of assurance and conviction upon any subject.

Sometimes, the availability of more evidence for a conclusion provides a reason to believe in its falsity. This counter-intuitive phenomenon is related to the idea of higher-order evidence, which has attracted broad interest in recent epistemological literature. Occasionally, providing more evidence for something weakens the case in its favor, by casting doubt on the probative value of other evidence of the same sort or on the fact-finder’s cognitive performance. We analyze this phenomenon, discuss its rationality, and outline possible (...) application to evidence law and to the law in general. It is suggested, inter alia, that such higher-order evidence may explain how judicial experience-based expertise in fact-finding is possible despite the absence of a feedback mechanism; and that fact-finders’ self-doubt regarding their own competence in making ‘beyond-reasonable doubt’ judgments might be reasonable and should not be ignored.

De Finetti was a strong proponent of allowing 0 credal probabilities to be assigned to serious possibilities. I have sought to show that (pace Shimony) strict coherence can be obeyed provided that its scope of applicability is restricted to partitions into states generated by finitely many ultimate payoffs. When countable additivity is obeyed, a restricted version of ISC can be applied to partitions generated by countably many ultimate payoffs. Once this is appreciated, perhaps the compelling character of the Shimony argument (...) will be less overwhelming and the attractiveness of de Finetti's more permissive attitude will become more apparent.I want to push the permissive tendency in de Finetti still further. It seems doubtful that RUIWC should be required as de Finetti apparently suggested. It is also excessively dogmatic and restrictive to require that the credal states of ideally situated rational agents be numerically definite (Levi 1974, 1980). And de Finetti's rejection of objectivism in statistics overreached itself when he dismissed objective probabilities as meaningless metaphysical artefacts (Levi 1986). In this respect, the philosophically most important lessons de Finetti has to teach us are to be found not in his celebrated representation theorem but in his discussions of the relations between 0-probability and possibility, conditional probability and countable additivity. Perhaps, the technical issues involved are remote and pedantic. But the attitude de Finetti sought to inculcate is of profound importance. (shrink)

In this paper I shall try to give you a good reason for sharing with Peirce his doubts on Pragmatism. What I am going to maintain is that Peirce found in his Semeiotic, through which he was looking for a real “proof” for pragmatism, hints, vanishing points that made him think that pragmatism was just a part of a richer logical realm and of a far richer reality. What he doubted was not pragmatism in itself but that it could comprehend (...) the whole realm of logic. The key of the point that I want to make is the famous “rational instinct”, but in order to understand its role and function I have to go through some clues that it is possible to find in the first branch of semeiotics and then to confirm my analysis with a brief reference to Methodeutics. In the end I will suggest that these reasons, which urged Peirce to increase the importance of the rational instinct, are the same that lie beneath his latest and worse known ideas on continuity and infinity. It is well known that in his late years Peirce was dealing with many things: he was writing “The Amazing Mazes of Mathematics”, he was trying to develop his theory of continuity and he was trying to re-publish his papers on Pragmatism with some correction. In the confused manuscripts of this last period of his life you can find, whatever was the topic he was talking about, questions on which he kept pondering again and again. In doing this kind of analysis Peirce often stated points that do not have a precise development or that cannot find a precise collocation in his synthetic statements. Therefore, what I am going to do is to underline these points and then to try drawing a conclusion that can account for them. The only problem of this task is due to the unavoidable brevity of a paper so that my discourse will probably look more a chain not stronger that is its weakest link than a cable whose every fiber helps the strength of the whole.

Most legal evidence scholars agree that proof of guilt beyond a reasonable doubt requires the belief that the defendant probably committed the alleged acts. However, they also agree that this is not a sufficient condition, as this belief may be unreasonable. I focus on two popular proposals for additional conditions: (i) that the degree of belief should be robust and (ii) that it should be reasonable given the available evidence (should be an evidential probability). Both criteria face difficulties regarding (...) their meaning and utility. I propose an interpretation which overcomes these difficulties and which combines the two conditions into a single criterion on which both conditions are about the possibility of overlooked, exculpatory information. Proof of guilt beyond a reasonable doubt requires that we are sufficiently certain that we did not miss such information for the sake of achieving accurate beliefs and a just error distribution. How certain we can be that we did not miss anything relevant depends on our higher-order evidence. One important type of higher-order evidence is whether the hypotheses under consideration are sufficiently detailed. This point leads to a novel way of combining the Bayesian and explanation-based accounts of rational legal proof. (shrink)

For Charles Peirce, the project of inquiry is a social one. Though inquiry, the passage from genuine doubt to settled belief, can be described on the individual level, its significance as a human activity is manifested in collective action. For any individual, Truth transcends experience and inquiry. But it does not transcend experience and inquiry altogether: is a fixed limit, an ideal, towards which a properly functioning community converges. What, in principle, makes the cohesion of such a community (...) class='Hi'>possible? Why did Peirce believe that convergence towards an ultimate conclusion was the necessary end of unlimited scientific inquiry? This essay examines Peirce's notion of community to answer these questions and suggests that the presence of genuine doubt not only makes convergence possible, but also constitutes the starting point for almost all inquiry. The exception is philosophical inquiry. (shrink)

Kirsten Besheer has recently considered Descartes’ doubting appropriately in the context of his physiological theories in the spirit of recent important re-appraisals of his natural philosophy. However, Besheer does not address the notorious indubitability and its source that Descartes claims to have discovered. David Cunning has remarked that Descartes’ insistence on the indubitability of his existence presents “an intractable problem of interpretation” in the light of passages that suggest his existence is “just as dubitable as anything else”. However, although the (...) cogito argument is widely thought to be central to the force of Descartes’ indubitability, for his part, Cunning does not consider its relevance and force. Accordingly, this article is concerned with the cogito argument and the question central to Hintikka’s seminal contribution, described by Cottingham as “Perhaps the most debated question,” namely, whether or not the cogito can be construed as a logical inference. Clearly, an inferential account has the potential to explain the certainty of Descartes’ conclusion that he exists. Recently, Sarkar offers what he characterizes as “novel and fairly conclusive reasons why the cogito cannot be construed as an argument,” asserting “the discovery of the cogito can only be an intuition not a deduction.” Obviously, it would greatly support the opposing inferential construal if a remotely plausible logical argument could be proposed. Toward this end, I defend the virtues of my ‘Diagonal’ account of Descartes’ cogito Above all, I show how my analysis meets the requirement that any satisfactory solution to the problem of the cogito would reconcile Descartes’ claim that the cogito is a certain inference with his claim that it is an intuitive kind of knowledge. Through a critical discussion of analyses such as that of Gallois , I show that it is possible to provide a textually faithful analysis that permits seeing the cogito as both inference and intuition because it may be seen as an exercise in the mathematical method of Analysis. Above all, as Feldman requires, I show that the Diagonal account is not only textually elegant, but permits crediting Descartes with a worthy insight, thereby resolving the tension between what Howell has termed the Humean and Cartesian problems, namely, the elusiveness and the certainty of the self.

Sir David Ross introduced and discussed his notion of prima facie duties in chapter 2 of The Right and the Good , and it is to this chapter that I shall devote most attention. I wish to show that the distinction between prima facie and “actual” duties, as expounded by Ross, entails that there are no “actual” duties; and I wish to show that this unfortunate consequence of the distinction arises from Ross's explicit epist-emological views. Writers such as Ewing, Baier (...) and Frankena, who have quoted Ross's distinction with some degree of approval, force one to ask how, precisely, they interpreted it. In the first part of this paper I set out Ross's exposition in detail, since failure to do this has blinded adherents to its difficulties; in the second part I summarise my findings and indicate the problems Ross rightly poses for us; in the third part I suggest possible sources for Ross's views. Two points should be noted at the outset. Firstly, the distinction applies to acts, not actions; “act” refers to “the thing done, the initiation of change, and ‘action’ the doing of it, the initiating of change, from a certain motive” . Secondly, the term “right” is used throughout as synonymous with “what is my duty”. (shrink)

In the present paper I shall argue that the real problem here is the very idea that there is a dilemma that compels us to choose sides. We can hold both that the meditator's doubts are fully serious, and that they leave the perspective of common sense largely unscathed. The key to dissolving the dilemma is to see that the meditator observes a distinction between two levels of epistemic standards: the very demanding standards appropriate to certainty, understood in a rather (...) technical sense of that term; and the commonplace standards appropriate to reasonable belief. The significance of this levels distinction has not been widely appreciated but it has important consequences both for how we are to understand the skepticism about the senses that is at issue and for appreciating the extent to which Descartes acknowledges and retains our natural trust in the senses. I aim to show that the meditator’s skepticIsm about the senses specifically concerns the possibility of sensory certainties, and is quite serious. It is intended to lead one to a stable change of mind about what is most certain. But a skepticIsm about sense-based certainty leaves the matter of whether experience provides a reliable basis for belief untouched by reasonable doubt. Since the meditator's doubts presuppose very demanding standards they have no bearing on our assessments from within the common sense perspective. I defend this view by arguing that the methodological 'withdrawal of assent' from perceptual beliefs is a mere pretense that is compatible with continued endorsement. Despite the seriousness with which the method of doubt is pursued, there is an important sense in which the meditator never doubts the basic deliverances of his senses. This helps explain the practical insulation of perceptual beliefs from skepticism. With one minor qualification, the meditator retains his natural trust in the senses throughout - although Descartes’ rhetoric sometimes suggests otherwise. Note that I shall be exploring the skepticism about the senses as we find it in the First Meditation. This paper does not purport to discuss all of the skeptical doubts of the First Meditation, e.g., skepticism about mathematical truths, God's existence and reason. Instead I shall focus solely upon the ways in which the meditator's doubts bear on his perceptual beliefs. The rationale for this restriction is twofold: 1) in the first place Descartes describes the general aim of the skeptical doubts of the First Meditation m terms of 'freeing us from our preconceived opinions, and providing the easiest route by which the mind may be led away from the senses’. I am specifically concerned to qualify this ambition and argue that Descartes retains throughout his preconceived trust in the reliability of the senses; and 2) the Meditations has long been thought to provide the grounds for a radical form of external world skepticism which not only denies us knowledge of, but also any reason to believe in, the existence of an external world. My discussion of Descartes' perceptual doubts is intended to show just how distant any such skepticism is from Descartes' own thoughts and intentions. (shrink)

M z ,f any have suggested that the findings of social choice theory demonstrate that there can be no "will of the people." This has subversive implications for our intuitive concept of self-government. I explore the relation between the notion of a "social will," that of self-government, and the impossibility theorems of social choice theory. I conclude that although the concept of the social will is essential to that of self-government, the findings of social choice theory do not cast (...) class='Hi'>doubt upon the possibility of either. Unlike many attempts to respond to the threat posed by social choice theory, my argument does not require any appeal to the problematic notion of the common good. (shrink)

Techniques for achieving moral enhancement will modify brain processes to produce what is alleged to be more moral conduct. Neurophilosophy and neuroethics must ponder what “moral enhancement” could possibly be, if possible at all. Objections to the very possibility of moral enhancement, raised from various philosophical and neuroscientific standpoints, fail to justify skepticism, but they do place serious constraints on the kinds of efficacious moral enhancers. While there won't be a “morality pill,” and hopes for global moral enlightenment will (...) remain hopes, there will be a large variety of behavioral modifiers described as enhancers of some aspect of morality or another according to prevailing social norms. The most likely moral enhancers that will be designed, tested, and marketed in the near future will attempt to alleviate seriously immoral and illegal behavior. Some enhancers diminishing antisocial conduct and a few designed to elevate moral conduct above normal levels will also become available, although their widespread use is doubtful. There will also be specialized modifications for enhancing whatever an individual personally regards as moral, and for enabling better performance by a person in an operational role. A measure of skepticism toward all the proposed kinds of moral enhancement is advised, and where political implementation of moral enhancers is concerned, a healthy amount of cynicism as well.

Did Descartes manage to overcome the skeptics? If we understand “overcome” in the sense of “refute,” the answer is no, since his hyperbolic doubt harbors several blind spots and is, therefore, not as radical as is commonly argued. In this way, the victory of the cogito is perhaps less decisive and fruitful than it is claimed. If we understand “overcome” in the sense of “remove” or “move beyond,” the answer is yes. Descartes has overcome skepticism, but at the cost (...) of a decision, a sort of bet made in favor of reason based on a confidence in the human mind that is never really subverted. This faith in reason, truth, and specific epistemological principles in Descartes’ philosophy constitute what Wittgenstein calls “hinges,” which are indispensable for doubting and searching for truth. In this sense, Descartes’ anti-skepticism is more a confidence in reason in order to save the possibility of science than the result of a logical refutation. (shrink)

In September 2006, when 45 scholars and activists from 19 countries around the world gathered amid the spires and gargoyles of Oxford for a conference entitled, “Hope: Probing the Boundaries,” complex dialectics of hope and despair circulated through the meeting rooms by day, and the conversations in quadrangles and pubs late into the night. On the one hand, the remarkable social and political openings and possibilities of the previous decade, from Berlin to Johannesburg, Leningrad to the Lacandon jungle of Chiapas, (...) seemed to be ever-more constrained by political and economic forces as brutal as those that preceded them, but, on the other hand, there were the Zapatistas and a thousand other movements persisting in the belief that, to echo the mantra of the World Social Forums, “another world is possible,” and there we were from around the world, to do the work of theorizing, describing, and enacting the persistence of individual and collective hope despite grim realities. The essays developed from that conference and collected here reflect both the theoretical and philosophical underpinnings and the cultural and political praxes of “hope against hope.”. (shrink)

The ‘error theory’ holds that all normative claims are false. Of course, if there is any reason to believe the error theory then, since it would be a reason to believe something, that would show the error theory itself to be false. A recent book (Streumer, 2017) tries to block this argument by arguing on the basis of the claim that the error theory itself can’t be believed that there can be no reason to believe it. This is a paradoxical (...) conclusion since it leaves the possibility that the error theory is true even though it is impossible to believe it and we can have no reason to believe it. In this paper I argue for a different paradox. Even if we can believe the error theory, we are committed to rejecting it, but this still leaves normative skepticism unanswered. (shrink)

Possibilities haunt history. The force of our explanations of events turns on the alternative possibilities these explanations suggest. It is these possible worlds which give us our understanding; and in human affairs we decide them by practical rather than theoretical judgement. In his widely acclaimed account of the role of counterfactuals in explanation, Geoffrey Hawthorn deploys extended examples from history and modern times to defend his argument. His conclusions cast doubt on existing assumptions about the nature and place (...) of theory, and indeed of the possibility of knowledge itself, in the human sciences. (shrink)

This article considers the contribution of Husserlian transcendental phenomenology to the scientific realism debate by thematizing the problem of dubitability. After first considering the rigorous standards for apodictic evidence in phenomenology, particularly in terms of the intuitive givenness of evidence, I consider how scientific theory is open, in principle, to doubt. I argue that phenomenology has both a critical and descriptive function for scientific theory: it clarifies what scientific theory can or cannot tell us about the world, both possibly (...) and necessarily; and it describes the meaningfulness that scientific theory can have for us in our experience of the world—that is, in the living flow of conscious experience that is indubitably real. As such, I explain how phenomenology can take scientific theory as a serious field of investigation. (shrink)

George Bowles and Thomas Gilbert claim that illatives such as so, therefore, and hence convey the meaning that the premise confers upon the conclusion a probability greater than 1/2. This claim is false, for there are straightforward uses of these illatives that do not convey the meaning that the probability is greater than 1/2. In addition, because Bowles' and Gilbert's claim is false, a revision of their definition of argument is required.
