Sayer argues that Popper defended a logicist philosophy of science. The problem with such logicism is that it creates what is termed here as a `truncated foundationalism', which restricts epistemic certainty to the logical form of scientific theories whilst having nothing to say about their substantive contents. Against this it is argued that critical realism, which Sayer advocates, produces a linguistic version of truncated foundationalism and that Popper's problem-solving philosophy, with its emphasis on developing knowledge through (...) criticism, eschews all forms of foundationalism and is better able to account for the development of substantive knowledge claims. Key Words: critical realism • fallibilism • logicism • post-positivism • truncated foundationalism. (shrink)

Divine Foundationalism is the thesis that God is the source of all things (apart from God hirself). I clarify and defend the thesis, before I consider the main arguments for and against it.

The editor's introduction to the volume explores the thesis of a convergence between analytic and hermeneutic philosophy on the absence of grounds for knowledge and practice. The nature of philosophy without foundations is discussed, along with the conservative tendencies and utopian tensions of "anti-foundationalism.".

Some facts ground other facts. Some fact is fundamental iff there are no other facts which partially or fully ground that fact. According to metaphysical foundationalism, every non-fundamental fact is fully grounded by some fundamental fact(s). In this paper I examine and defend some neglected considerations which might be made in favor of metaphysical foundationalism. Building off of work by Ross Cameron, I suggest that foundationalist theories are more unified than, and so in one important respect simpler than, (...) non-foundationalist theories, insofar as foundationalist theories allow us to derive all non-fundamental facts from some fundamental fact(s). Non-foundationalist theories can enjoy a similar sort of theoretical unification only by taking on objectionable metaphysical laws. (shrink)

According to foundationalism, some beliefs are justified but do not depend for their justification on any other beliefs. According to access internalism, a subject is justified in believing some proposition only if that subject is aware of or has access to some reason to think that the proposition is true or probable. In this paper I discusses a fundamental challenge to internalist foundationalism often referred to as the Sellarsian dilemma. I consider three attempts to respond to the dilemma (...) – phenomenal conservatism, BonJour’s classical foundationalism, and Fumerton’s classical foundationalism. I argue that, of these three, only the last seems to avoid getting impaled on one or the other horn of the dilemma. I end by responding to some concerns with Fumerton’s account. (shrink)

Foundationalist theories of justification attempt to solve the Agrippa problem by finding some way of bringing the infinite regress of reasons to a nonarbitrary halt. This chapter concentrates on Chisholm's attempt to do this. Such a theory faces a double task: the first is to find suitable starting points that do not themselves stand in need of justification – Chisholm appeals to what he calls self‐presenting properties to do this. The second is to show that from these starting points, a (...) suitably large domain of those knowledge claims that we take to be justified is justified. Criticisms are offered of both parts of this program. It is also argued that, in various places, Chisholm begs the question against skepticism. (shrink)

Experiential Foundationalism, Linguistic Practice, and Historicity.

Nonskeptical foundationalists say that there are basic beliefs. But, one might object, either there is a reason why basic beliefs are likely to be true or there is not. If there is, then they are not basic; if there is not, then they are arbitrary. I argue that this dilemma is not nearly as decisive as its author, Peter Klein, would have us believe.

According to memory foundationalism, seeming to remember that P is prima facie justification for believing that P. There is a common objection to this theory: If I previously believed that P carelessly (i.e. without justification) and later seem to remember that P, then (according to memory foundationalism) I have somehow acquired justification for a previously unjustified belief. In this paper, I explore this objection. I begin by distinguishing between two versions of it: One where I seem to remember (...) that P while also seeming to remember being careless in my original believing that P and the other where I seem to remember that P while not seeming to remember my past carelessness. I argue that the former case is the real challenge for memory foundationalism. After establishing the case of unforgotten carelessness as objection to memory foundationalism, I recast memory foundationalism in way that allows it to escape this objection. (shrink)

In Justification without Awareness (2006), Michael Bergmann presents a dilemma for internalism from which he claims there is “no escape”: The awareness allegedly required for justification is either strong awareness, which involves conceiving of some justification-contributor as relevant to the truth of a belief, or weak awareness, which does not. Bergmann argues that the former leads to an infinite regress of justifiers, while the latter conflicts with the “clearest and most compelling” motivation for endorsing internalism, namely, that for a belief (...) to be justified its truth must not be an accident from the subject’s perspective. Bergmann’s dilemma might initially seem to have the force of a knock-down argument against the classical foundationalist accounts he considers, if not against all forms of internalism. I argue, however, that the weak-awareness horn of Bergmann’s dilemma is unsuccessful. Classical foundationalists can hold on to the main motivation for internalism and avoid a vicious regress of justifiers. (shrink)

This book addresses the breach within contemporary philosophy with a newly conceived foundationalism. It shows that dramatic discord has arisen between its two dominant branches. The Anglo-American branch generally takes its departure from logic and from natural science, while the Continental branch generally takes its departure from art and from the great traditional questions. However, they share this common negative feature: each side denies the view that philosophy issues from a central foundation. The book gives brief distillations of six (...) major Anglo-American figures: Carnap, James, Quine, Davidson and Kripke; as well as six major Continental figures: Husserl (the only foundationalist), Heidegger, Merleau-Ponty, Derrida, Gadamer, and Sallis. In each, the author discovers a hidden foundation called ruling image that animates the philosopher's thought. (shrink)

Infinitists argue that their view outshines foundationalism because infinitism can, whereas foundationalism cannot, explain two of epistemic justification’s crucial features: it comes in degrees and it can be complete. I present four different ways that foundationalists could make sense of those two features of justification, thereby undermining the case for infinitism.

This chapter has two goals: to motivate the foundationalist solution to the regress problem and to defend it against arguments from Sellars, BonJour and Klein. Both the motivation and the defence of foundationalism raise larger questions about the relationship between foundationalism and access internalism. I argue that foundationalism is not in conflict with access internalism, despite influential arguments to the contrary, and that access internalism in fact supplies a theoretical motivation for foundationalism. I conclude that (...) class='Hi'>foundationalism and access internalism form a coherent and well-motivated package. (shrink)

Foundationalists distinguish basic from nonbasic beliefs. At a first approximation, to say that a belief of a person is basic is to say that it is epistemically justified and it owes its justification to something other than her other beliefs, where “belief” refers to the mental state that goes by that name. To say that a belief of a person is nonbasic is to say that it is epistemically justified and not basic. Two theses constitute Foundationalism: (a) Minimality: There (...) are some basic beliefs, and (b) Exclusivity: If there are any nonbasic beliefs, that is solely because they (ultimately) owe their justification to some basic belief. Proponents of Minimality but not Exclusivity endorse Minimal Foundationalism. Proponents of Exclusivity but not Minimality endorse either Epistemic Nihilism, the view that there are no justified beliefs, or some non-foundationalist epistemology such as Coherentism or Infinitism. In this essay I aim to characterize the notion of a basic belief more precisely and to assess some arguments for and against Foundationalism. In the process, I hope to exhibit the resilience and attractiveness of Foundationalism. (shrink)

Epistemological foundationalism is best conceived as a thesis about the structure of a body of knowledge. Although its major proponents have been non-skeptics, the thesis may be construed as neutral with respect to skepticism. A modest version of epistemological foundationalism so construed might be formulated as the view that necessarily, if one has any knowledge, one has some direct knowledge, i.e., knowledge not based on other knowledge or beliefs one has, and any further knowledge one has is at (...) least in part based on one’s direct knowledge. Now suppose we make four plausible assumptions which most foundationalists would accept: each of us has knowledge, knowing entails believing, we each have at least some direct knowledge constituted by beliefs not based on other beliefs of ours, and if a person has direct knowledge on which other knowledge is based, at least some of the beliefs constituting the former are not based on other beliefs of his. Given -, epistemological foundationalism apparently entails some form of what I shall call psychological foundationalism. In its simplest form, this is the view that the structure of a person’s body of beliefs is foundational in the strong sense that some of his beliefs are not based on others, and any other beliefs he has are based on the former.

There is a long-standing debate in epistemology on the structure of justification. Some recent work in formal epistemology promises to shed some new light on that debate. I have in mind here some recent work by David Atkinson and Jeanne Peijnenburg, hereafter “A&P”, on infinite regresses of probabilistic support. A&P show that there are probability distributions defined over an infinite set of propositions {\ such that \ is probabilistically supported by \ for all i and \ has a high probability. (...) Let this result be “APR”. A&P oftentimes write as though they believe that APR runs counter to foundationalism. This makes sense, since there is some prima facie plausibility in the idea that APR runs counter to foundationalism, and since some prominent foundationalists argue for theses inconsistent with APR. I argue, though, that in fact APR does not run counter to foundationalism. I further argue that there is a place in foundationalism for infinite regresses of probabilistic support. (shrink)

Standard views about metaphysical structure presume that if metaphysical structure is hierarchical, any priority ordering of individuals is rigid or situationally invariant. This paper challenges this presumption. The challenge derives from an effort to interpret the kind of metaphysical structure implicit in writings central to the Huayan tradition of Chinese Buddhism. The Huayan tradition views reality as a realm of thoroughgoing interdependence. Close attention to primary sources indicates that this view does not fit comfortably in any of the metaphysical structures (...) familiar from contemporary analytic metaphysics. Accordingly, this paper also develops a conception of metaphysical structure that rejects the standard presumption. Motivation for this conception derives from attending to certain formal analogies between kinds of metaphysical structure and kinds of social organization. These analogies provide guidance for a conception of metaphysical structure as heterarchical or situationally variable. This conception breaks new ground for analytic metaphysics and opens conceptual space for interpreting Huayan metaphysics as a heterarchical variation of foundationalism. (shrink)

An influential tradition in the philosophy of causation has it that all token causal facts are, or are reducible to, facts about difference-making. Challenges to this tradition have typically focused on pre-emption cases, in which a cause apparently fails to make a difference to its effect. However, a novel challenge to the difference-making approach has recently been issued by Alyssa Ney. Ney defends causal foundationalism, which she characterizes as the thesis that facts about difference-making depend upon facts about physical (...) causation. She takes this to imply that causation is not fundamentally a matter of difference-making. In this paper, I defend the difference-making approach against Ney’s argument. I also offer some positive reasons for thinking, pace Ney, that causation is fundamentally a matter of difference-making. (shrink)

Semantic holists view what one's terms mean as function of all of one's usage. Holists will thus be coherentists about semantic justification: showing that one's usage of a term is semantically justified involves showing how it coheres with the rest of one's usage. Semantic atomists, by contrast, understand semantic justification in a foundationalist fashion. Saul Kripke has, on Wittgenstein's behalf, famously argued for a type of skepticism about meaning and semantic justification. However, Kripke's argument has bite only if one understands (...) semantic justification in foundationalist terms. Consequently, Kripke's arguments lead not to a type of skepticism about meaning, but rather to the conclusion that one should be a coherentist about semantic justification, and thus a holist about semantic facts.

The tendency to attribute foundationalist ambitions to the Vienna Circle has long obscured our view of its attempted revolution in philosophy. The present paper makes the case for a consistently epistemologically anti-foundationalist interpretation of all three of the Circle's main protagonists: Schlick, Carnap, and Neurath. Corresponding to the intellectual fault lines within the Circle, two ways of going about the radical reorientation of the pursuit of philosophy will then be distinguished and the contemporary potential of Carnap's and Neurath's project explored.

Epistemological foundationalism has typically been thought to hold that in order to account for human knowledge we must countenance the direct Justification of some specific kind of beliefs, such as one's beliefs to the effect that one is having a certain sensation. How else, it may be thought, can one analyse Justification without confronting an infinite regress or a vicious circle? I believe that this conception of foundationalism has been so influential that most foundationalists and nearly all their (...) critics have failed to appreciate that foundationalism may be plausibly construed as a thesis mainly about the structure of a body of Justified beliefs. Central to the thesis, so interpreted, is that one's Justified beliefs divide into foundations and superstructure; but no particular content on the part of either set of beliefs need be required. This latitude regarding content is altogether appropriate; for if we use, as a guide to understanding foundationalism, the famous regress argument, from which the thesis derives much of its plausibility, then the only foundations required by the thesis are beliefs whose Justification does not depend on that of other beliefs. Precisely what beliefs these are is a controversial matter on which foundationalists may differ. (shrink)

Foundationalism is a view about the structure of knowledge and justification. The heart of the thesis is the claim that if there is any knowledge or justified belief at all, then there is a kind of knowledge and justified belief that does not require inference from something else known or justifiably believed. This Element begins by exploring abstract arguments for foundationalism and against proposed alternatives. It then explores disagreements among foundationalists about how to understand foundational knowledge and justified (...) belief, what is plausibly included in the foundations, and what is required for legitimate inference from foundations to the rest of what we believe. The author argues for the conclusion that one can combine insights captured by different versions of foundationalism by making a distinction between ideal justification and justification that falls short of that ideal.

Neuroscience offers more than new empirical evidence about the details of cognitive functions such as language, perception and action. Since it also shows many functions to be highly distributed, interconnected and dependent on mechanisms at different levels of processing, it challenges concepts that are traditionally used to describe these functions. The question is how to accommodate these concepts to the recent evidence. A recent proposal, made in Philosophical Foundations of Neuroscience (2003) by Bennett and Hacker, is that concepts play a (...) foundational role in neuroscience, that empirical research needs to presuppose them and that changing concepts is a philosophical task. In defending this perspective, PFN shows much neuroscientific writing to be dualistic in nature due to our poor grasp of its foundations. In our review article we take a different approach. Instead of foundationalism we plead for a mild coherentism, which allows for a gradual and continuous alteration of concepts in light of new evidence. Following this approach it is also easier to deal with some neurological conditions (like blindsight, synaesthesia) that pose difficulties for our concepts. Finally, although words and concepts seem to seduce us to thinking that many skills and tasks function separately, it is language skill that – as neuroscientific evidence shows – co-emerges with action/perception cycles and thus seems to require revision of some of our central concepts.

Memory has eluded a unified philosophical analysis for millennia because memory isn’t a single type of mental state. On a standard classification, procedural memory is memory of how to do things, semantic memory is memory of facts or fact-like propositions and episodic memory is memory of events in which you partook. Autobiographical memory is memory of what happened in your past in real-life cases. Empirical studies suggest that autobiographical memory is a construction of pieces of past experiences. This points to (...) a view of memory according to which we have no direct awareness of what happened in the past and hence no internal justification of what we seem to remember happened. Here I argue that a version of phenomenal dogmatism, the view that seemings can justify higher-order mental states immediately and fully in the absence of defeaters, is plausible for memories and that it bypasses a common route from a constructionist view of memory to skepticism about the past.

Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist withoutother (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa.

Foundationalism, a theory about the structure of epistemic justification, is often criticized for excesses that are unnecessary additions to it. But when correctly understood, its main tenets (featuring most prominently the claim that there can be properly basic beliefs) are virtually undeniable. The best way to get at the heart of foundationalism is to focus not on Descartes but on Aristotle and his famous regress argument. Section I unpacks that foundationalist argument. Section II addresses some objections to (...) class='Hi'>foundationalism. Section III considers how foundationalism bears on topics in the epistemology of theology—topics such as Reformed epistemology, natural theology, Biblical criticism, and post-foundationalism.

In this paper I argue that internalistic foundationalist theories of the justification of memory belief are inadequate. Taking a discussion of John Pollock as a starting point, I argue against any theory that requires a memory belief to be based on a phenomenal state in order to be justified. I then consider another version of internalistic foundationalism and claim that it, too, is open to important objections. Finally, I note that both varieties of foundationalism fail to account for (...) the epistemic status of our justified nonoccurrent beliefs, and hence are drastically incomplete. (shrink)

_The traditional philosophical concept of justified belief, a cornerstone of epistemology, faces unprecedented challenges in the digital age. The rise of social media, online information overload, and the proliferation of echo chambers have cast doubt on the possibility of establishing reliable knowledge claims in a networked environment. This article argues that the foundationalist approach to justified belief, which emphasizes individual justification based on private evidence, is no longer tenable in this new context. Instead, we propose a networked epistemology that emphasizes (...) the role of social networks and distributed knowledge in constructing justified beliefs. We draw on insights from social epistemology, philosophy of science, and cognitive science to develop a framework for understanding how individuals and communities can collaboratively arrive at reliable knowledge claims in the face of information overload and conflicting perspectives. This paper explores the contemporary challenges to traditional epistemological frameworks, specifically focusing on foundationalism, in the context of our increasingly interconnected and networked age. As information dissemination becomes more rapid and diverse, the traditional model of justified belief rooted in foundational principles faces significant challenges. In this inquiry, we propose a shift towards a networked epistemology that acknowledges the dynamic and interdependent nature of beliefs in the digital era. Drawing upon insights from philosophy, cognitive science, and information theory, we argue for a reconceptualization of justified belief that recognizes the complex interplay of interconnected nodes of knowledge. By examining the implications of this shift, we aim to contribute to a more nuanced understanding of how individuals form and justify beliefs in a world characterized by information abundance and digital interconnectedness._.

It is no part of my purpose in this paper to advocate Minimal Foundationalism. In fact I believe there to be strong objections to any form of foundationalism, and I feel that some kind of coherence or contextualist theory will provide a more adequate general orientation in epistemology. Will and Lehrer are to be commended for providing, in their different ways, important insights into some possible ways of developing a nonfoundationalist epistemology. Nevertheless if foundationalism is to be (...) successfully disposed of it must be attacked in its most defensible, not in its most vulnerable, form. Although Will and Lehrer reveal weaknesses in historically important forms of foundationalism, it has been my aim in this paper to show that their arguments leave untouched the more modest and less vulnerable form I have called ‘Minimal Foundationalism’, a form approximated to by the most prominent contemporary versions of the position. It is to be hoped that those who are interested in clearing the decks for an epistemology without foundations will turn their critical weapons against such modest and careful foundationalists as Chisholm, Danto, and Quinton.

My aim in this paper is to explore the dispute between foundationalism and coherentism and attempt a resolution. I will begin by considering the origin of the issue in the famous epistemic regress problem. Next I will explore the central foundationalist idea and the most central objections that have been raised against foundationalist views. This will lead to a consideration of the main contours of the coherentist alternative, and eventually to a discussion of objections to coherentism – including several (...) specific ones that I now judge to be clearly fatal, especially when taken together. This will motivate, finally, a reconsideration of foundationalism. I will argue that the dialectically most serious objection to foundationalism can be successfully answered. While the answer that I will suggest admittedly carries with it the price of aggravating certain other difficulties, especially the venerable problem of showing how belief in an external world of physical objects can be justified, it still seems to me to leave foundationalism as by far the more defensible and promising of the two alternatives.

This paper compares and contrasts the epistemologies of Rawls and Dworkin, both usually presented as either Kantian or pragmatist. It considers in particular the main pragmatist theses underlying their work, namely anti-metaphysics, anti-skepticism, fallibilism and objectivity as conditioned by practice, as well as their account of truth. It then examines an approach which takes Rawls’ epistemology as “anti-foundationalist” and argues that, to the extent that this qualification is connected to deliberative democracy, it should not be accepted without reservation as an (...) adequate account of the views of either philosopher.

I propose a version of foundationaUsm with the following distinctive features. First, it includes in the class of basic beliefs ordinary beliefs about physical objects. This makes it unrestricted. Second, it assigns the role of ultimate justifiers to A-states: states of being appeared to in various ways. Such states have propositional content, and are justifiers if they are presumptively reliable. The beliefs A-states justify are basic if they are non-inferential. In the last three sections of the paper, I defend this (...) version of foundationalism against Sellars's famous anti-foundationalist dilemma, according to which sense-experiential states can't be justifiers ifthey lack propositional content, and can't terminate the justificatory regress if they have propositional content. I argue that the latter of these two claims is false. A-states can play the role of justifiers because they have propositional content, and they can terminate the justificatory regress because they themselves are capable of neither being true or false, nor being justified or unjustified.

Alvin Plantinga declared in 1983 that Classical Foundationalism had collapsed. He was convinced that he had found an utterly damaging argument against CF: CF is self-referentially incoherent. Already Alston (1985) and Quinn (1985 and 1993) and recently DePoe (2007) have denied that Plantinga’s argument is successful. There are three objections against his argument:i) He has to show that there is no argument for CF; ii) there may be an inductive argument for CF; iii) there are other good arguments for (...) CF, presented e.g. by Richard Fumerton. In this paper I will argue that i) is wrong and that Quinn’s inductive argument (ii) fails. Plantinga has shown that the “old” type of CF is self-refuting. Plantinga’s argument is not successful if aimed against a contemporary Fumerton-style CF because this type of CF differs in at least one relevant aspect from the kind of CF Plantinga was struggling with.

In this paper, I argue that Humean theories of moral motivation appear preferable to Kantian approaches only if one assumes a broadly foundationalist conception of rational justification. Like foundationalist approaches to justification generally, Humean psychology aims to counter the regress-of-justification argument by positing a set of ultimate regress-stoppers-in this case, unmotivated desires. If the need for regress-stoppers of this type in the realm of practical deliberation is accepted, desires do indeed appear to be the most likely candidate. But if this (...) foundationalist strategy is rejected, there is no longer any reason to suppose that all motivation must be traceable to some extra-rational incentive. This clears the way for a rehabilitation of the Kantian claim that reasons for action can take the form of categorical imperatives. To illustrate this thesis, I show how a conception of practical rationality that incorporates a contextualist model of justification can be developed that treats social norms as reasons for action, without assigning any mediating role to agent desires. a theory of action of this type eliminates the gap between moral obligation and action, and so articulates the fundamental Kantian intuition that acting on the basis of moral principle-and with disregard for self-interest-is just one way of acting rationally.

In ancient times, the main approaches to metaphysical realism were intuitive. In modern times, foundationalism has replaced intuition as the main strategy to make out metaphysical realist claims to know. In On Foundationalism, Rockmore argues that foundationalism fails in all its known variants.

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism (...) is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism captures a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear. (shrink)

One important strand of Sellars’s attack on classical foundationalism from Empiricism and the Philosophy of Mind is his thesis about the priority of is-talk over looks-talk. This thesis has been criticized extensively in recent years, and classical foundationalism has found several contemporary defenders. I revisit Sellars’s thesis and argue that is-talk is epistemically prior to looks-talk in a way that undermines classical foundationalism. The classical foundationalist claims that epistemic foundations are constituted by the agent’s set of looks-judgments. (...) However, I argue that only a subset of these looks-judgments are even candidates to serve as foundations for the agent’s empirical knowledge, and membership in this subset is determined by the agent’s theory of how the world is. Thus, the epistemic force of the looks-judgments in this subset is dependent on the agent’s theory of how the world is. This means that these looks-judgments aren’t foundational at all, as the agent’s theory of how the world is is epistemically is prior to the epistemic status of these looks-judgments. This is the sense in which judgments about how the world is are epistemically prior to judgments about how things look. This conclusion allows concrete elaboration of another of Sellars’s well-know claims: “I do wish to insist that the metaphor of ‘foundation’ is misleading in that it keeps us from seeing that if there is a logical dimension in which other empirical propositions rest on observation reports, there is another logical dimension in which the latter rest on the former”.

Foundationalism in moral epistemology is a core tenet of ethical intuitionism. According to foundationalism, some moral beliefs can be known without inferential justification; instead, all that is required is a proper understanding of the beliefs in question. In an influential criticism against this view, Walter Sinnott-Armstrong has argued that certain psychological facts undermine the reliability of moral intuitions. He claims that foundationalists would have to show that non-inferentially justified beliefs are not subject to those defeaters, but this would (...) already constitute a form of inference and hence undermine the possibility of noninferential justification. The goal of my paper is to defend foundationalism against Sinnott-Armstrong’s criticism. After presenting his challenge, I first argue that the most promising objection to it fails. This objection makes the case that defeater-defeaters are not part of the justification, but merely preserve the justification which the original claim provides. I object to this argument by distinguishing between weak and robust defeaters; only weak defeaters, I argue, fall outside the scope of justification, and it is an open question whether Sinnott-Armstrong’s defeaters fall into that category. This leads the way to my own criticism of Sinnott-Armstrong’s challenge: foundationalists in moral epistemology are entitled to the use of defeater-defeaters as part of the justification for moral beliefs as long as those defeater-defeaters themselves do not entail moral claims. Therefore, Sinnott-Armstrong’s challenge does not undermine foundationalism. (shrink)

The phenomenon of mutual support presents a specific challenge to the foundationalist epistemologist: Is it possible to model mutual support accurately without using circles of evidential support? We argue that the appearance of loops of support arises from a failure to distinguish different synchronic lines of evidential force. The ban on loops should be clarified to exclude loops within any such line, and basing should be understood as taking place within lines of evidence. Uncertain propositions involved in mutual support relations (...) are conduits to each other of independent evidence originating ultimately in the foundations. We examine several putative examples of benign loops of support and show that, given the distinctions noted, they can be accurately modeled in a foundationalist fashion. We define an evidential "tangle," a relation among three propositions that appears to require a loop for modeling, and prove that all such tangles are trivial in a sense that precludes modeling them with an evidential circle.

A foundationalist account of our empirical thinking divides propositions we accept into two classes, basic and derivative, and sees the warrant of derivative propositions as accruing to them through their derivation from basic propositions. Such an account needs to answer two questions: which propositions are basic, and whence do basic propositions acquire their warrant? A natural and ancient answer to these questions is that basic propositions are observational and that these propositions gain their warrant from perceptions. I critically examine this (...) view and also a variant view offered by Wilfrid Sellars. I put forward an alternative conception, dialectical foundationalism, that sees the distinction between the basic and the derivative as issuing from a distinction between two kinds of reasoning, derivational and dialectical. This type of foundationalism provides a more accurate account of our empirical thinking, I argue, than its traditional and Sellarsian counterparts. (shrink)
