Here is a definition of knowledge: for you to know a proposition p is for you to have an outright belief in p that is correct precisely because it manifests the virtue of rationality. This definition resembles Ernest Sosa’s “virtue theory”, except that on this definition, the only virtue that must be manifested in all instances of knowledge is rationality, and no reductive account of rationality is attempted—rationality is assumed to be an irreducibly normative notion. This definition (...) is compatible with “internalism” about rationality, and with a form of “pragmatic encroachment” on the conditions of rational outright belief. An interpretation is given of this definition, and especially of the sense of ’because’ that it involves. On this interpretation, this definition entails that both safety and adherence are necessary conditions on knowledge; it supports a kind of contextualism about terms like ‘knowledge’; and it provides resources to defend safety, adherence, and contextualism, against some recent objections.

In this impressive second edition of Theory of Knowledge, Keith Lehrer introduces students to the major traditional and contemporary accounts of knowing. Beginning with the traditional definition of knowledge as justified true belief, Lehrer explores the truth, belief, and justification conditions on the way to a thorough examination of foundation theories of knowledge,the work of Platinga, externalism and naturalized epistemologies, internalism and modern coherence theories, contextualism, and recent reliabilist and causal theories. Lehrer gives all views (...) careful examination and concludes that external factors must be matched by appropriate internal factors to yield knowledge. This match of internal and external factors follows from Lehrer’s new coherence theory of undefeated justification. In addition to doing justice to the living epistemological traditions, the text smoothly integrates several new lines that will interest scholars. Also, a feature of special interest is Lehrer’s concept of a justification game.This second edition of Theory of Knowledge is a thoroughly revised and updated version that contains several completely new chapters. Written by a well-known scholar and contributor to modern epistemology, this text is distinguished by clarity of structure, accessible writing, and an elegant mix of traditional material, contemporary ideas, and well-motivated innovation.

Epistemology or the theory of knowledge is one of the cornerstones of analytic philosophy, and this book provides a clear and accessible introduction to the subject. It discusses some of the main theories of justification, including foundationalism, coherentism, reliabilism, and virtue epistemology. Other topics include the Gettier problem, internalism and externalism, skepticism, the problem of epistemic circularity, the problem of the criterion, a priori knowledge, and naturalized epistemology. Intended primarily for students taking a first class in (...) epistemology, this lucid and well-written text would also provide an excellent introduction for anyone interested in knowing more about this important area of philosophy.

A satisfactory theory of knowledge in which the shortcomings of a pure externalist account are avoided and in which the Gettier problem is solved should consist in a combination of externalist and internalist components. The internalist component should guarantee that the epistemic subject has cognitive access to the justifying grounds of her belief. And the externalist component should guarantee that the justification of her belief does not depend on any false statement. Keith Lehrer's coherence theory of (...) class='Hi'>knowledge as undefeated justification is an example of such an internalist-externalist analysis of knowledge. But nevertheless, Lehrer's account leads to unintended results. Therefore, it is argued that a satisfactory coherence theory of knowledge must also be based on a gradual notion of systematic coherence. (shrink)

Introduction As the title indicates, the chief focus of this book is epistemic justification. But just what is epistemic justification and what is its place ...

Most epistemologists agree that epistemic justification is required for knowledge. This requirement is usually formulated in one of two ways: S knows that p only if S is justified in believing that p. S knows that p only if S's belief that p is justified. Surprisingly and are generally regarded as synonymous formulations of the justification condition. In Chapter 1, I argue that such a synonymy thesis is mistaken and that, in fact, and specify substantively different requirements. requires that (...) the person be justified, whereas requires that the belief in question be justified, and intuitively, these constitute different requirements. Thus, it is concluded that and employ inherently different kinds of epistemic justification in their respective analysantia. I dub them "personal justification" and "doxastic justification", respectively. The remainder of the dissertation is devoted to demonstrating both the legitimacy and the importance of the personal/doxastic justification distinction. For example, the distinction helps account for the divergent intuitions that regularly arise regarding justificatory evaluations in demon-world contexts. ;In Chapters 2 and 3 I provide analyses for doxastic and personal justification. Chapter 2 spells out an externalist reliabilist account of doxastic justification which safely avoids demon-world counterexamples. Chapter 3 advances an internalist coherence account of personal justification. In defending this coherence theory, I argue that all foundation theories are false and that the regress argument on which they are predicated is unsound. ;In Chapter 4, I propose an analysis of ordinary knowledge which only requires doxastic justification. Nevertheless personal justification plays a negative, undermining role in the analysis. I then demonstrate that this analysis of knowledge is immune to typical Gettier examples. It also remains unscathed by Harman's beefed-up Gettier cases. Finally, I consider a stronger analysis of knowledge requiring both doxastic and personal justification. Though the latter analysis proves too strong for ordinary knowledge, it remains interesting as an analysis of a more intellectualistic kind of knowledge. ;The final chapter examines the internalist/externalist controversy and demonstrates that this controversy is yet another manifestation of the personal/doxastic justification conflation.

This paper presents the outlines of a phenomenological theory of foundational or non-inferential knowledge according to which the facts or states of affairs towards which our beliefs are intentionally directed can sometimes serve as reasons or evidence for what we believe. This occurs in acts of fulfillment, in which an object or state of affairs is given as it is thought to be. Hopp further argues that the sorts of empirical facts that can serve as reasons for noninferentially (...) justified beliefs are not confined to facts about one’s own occurrent mental states, but include facts about the physical world as well. In the course of defending the view against objections, Hopp argues that we should be internalists about the reasons in virtue of which what we believe is justified but externalists about the factors in virtue of which our states of believing have the status of being justified. He also argues against the claim that mental states, such as perceptual experiences, constitute our evidence for empirical beliefs. (shrink)

Internalism and Epistemology is a powerful articulation and defense of a classical answer to an enduring question: What is the nature of rational belief? In opposition to prevailing philosophical fashion, the book argues that epistemic externalism leads, not just to skepticism, but to epistemic nihilism - the denial of the very possibility of justification. And it defends a subtle and sophisticated internalism against criticisms that have widely but mistakenly been thought to be decisive. Beginning with an internalist response (...) to the Gettier problem, the authors deal with the problem of the connection to truth, stressing the distinction between success and rationality as critical to its resolution. They develop a metaregress argument against externalism that has devastating consequences for any view according to which epistemic principles are contingent. The same argument does not, they argue, affect the version of internalism they espouse, since its epistemic principles are analytic and knowable a priori. The final chapter addresses the problem of induction and shows that its solution turns critically on the distinction between success and rationality - the very distinction that lies at the heart of the dispute between internalists and externalists. Provocative, probing, and deliberately unfashionable, Internalism and Epistemology is a ringing defense of internalism that will interest specialists and students alike. It is essential reading for anyone who suspects that rumors of the death of traditional epistemology have been greatly exaggerated. (shrink)

This book is a sustained defence of traditional internalist epistemology. The aim is threefold: to address some key criticisms of internalism and show that they do not hit their mark, to articulate a detailed version of a central objection to externalism, and to illustrate how a consistent internalism can meet the charge that it fares no better in the face of this objection than does externalism itself. This original work will be recommended reading for scholars with an interest (...) in epistemology. (shrink)

Discrimination is a central epistemic capacity but typically, theories of discrimination only use discrimination as a vehicle for analyzing knowledge. This paper aims at developing a self-contained theory of discrimination. Internalist theories of discrimination fail since there is no compelling correlation between discriminatory capacities and experiences. Moreover, statistical reliabilist theories are also flawed. Only a modal theory of discrimination is promising. Versions of sensitivity and adherence that take particular alternatives into account provide necessary and sufficient conditions on (...) discrimination. Safety in contrast is not sufficient for discrimination as there are cases of safety that are clearly instances of discrimination failure. The developed account of discrimination between objects will be extended to discrimination between kinds and between types. (shrink)

I provide a novel knowledge-first account of justification that avoids the pitfalls of existing accounts while preserving the underlying insight of knowledge-first epistemologies: that knowledge comes first. The view I propose is, roughly, this: justification is grounded in our practical knowledge (know-how) concerning the acquisition of propositional knowledge (knowledge-that). I first refine my thesis in response to immediate objections. In subsequent sections I explain the various ways in which this thesis is theoretically superior to (...) existing knowledge-first accounts of justification. The upshot is a virtue-theoretic, knowledge-first view of justification that is internalist-friendly and able to explain more facts about justification than any other available view. (shrink)

Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be (...) known. The arguments are illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind.

This paper objects to internalist theories of justification from testimony on the grounds that they can’t accommodate intuitions about a pair of cases. The pair of cases involved is a testimonial version of the cases involved in the New Evil Demon Argument. The role of New Evil Demon cases in motivating contemporary internalist theories of knowledge and justification notwithstanding, it is argued here that testimonial cases make an intuitive case against internalist theories of justification from testimony.

This collection of papers (including three completely new ones) by one of the foremost philosophers in epistemology transcends two of the most widely misunderstood positions in philosophy--foundationalism and coherentism. Audi proposes a distinctively moderate, internalist foundationalism that incorporates some of the virtues of both coherentism and reliabilism. He develops important distinctions between positive and negative epistemic dependence, substantively and conceptually naturalistic theories, dispositional beliefs and dispositions to believe, episodically and structurally inferential beliefs, first and second order internalism, and rebutting (...) as opposed to refuting skepticism. These contrasts are applied not only to rational belief, but to rational action and the rationality of desires and intentions. The overall position is a pluralist, moderately rationalistic, internalist theory of justification and a partly externalist conception of knowledge. However, by virtue of offering a theory of rationality as well as an account of knowledge and justified belief, it will interest philosophers of ethics, science, and the social sciences and teachers and students of epistemology.

Judgment internalism about evaluative judgments is the view that there is a necessary internal connection between evaluative judgments and motivation understood as desires. The debate about judgment internalism has reached a standoff some time ago. In this paper, I outline a new argument for judgment internalism. This argument does not rely on intuitions about cases, but rather it has the form of an inference to the best explanation. I argue that the best philosophical explanations of how we (...) know what we desire require that judgment internalism is true, which gives us a good reason to believe that judgment internalism is true.

In this paper I discuss Kant’s theory of conscience. In particular, I explicate the following two claims that Kant makes in the Metaphysics of Morals: (1) an erring conscience is an absurdity and (2) if an agent has acted according to his/her conscience, then s/he has done all that can be required of him/her. I argue that (1) is a very specific claim that does not bear on the problem of moral knowledge. I argue that (2) rests on (...) a strongly internalist line of argument. (shrink)

In his Reflective Knowledge, Ernest Sosa offers a theory of knowledge, broadly virtue-theoretic in character, that is meant to transcend simple ways of contrasting "internalist" with "externalist" or "foundationalist" with "coherentist" approaches to knowledge and justification. Getting beyond such simplifications, Sosa thinks, is the key to finding an exit from "the Pyrrhonian Problematic": the ancient and profound skeptical problem concerning the apparent impossibility of validating the reliability of our basic epistemic faculties and procedures in a way (...) that escapes vicious circularity. Central to Sosa's anti-skeptical strategy is the claim that there are two kinds of knowledge. His thought is that animal knowledge, which can be understood in purely reliabilist terms, can ground justified trust in the reliability of our basic cognitive faculties, thus elevating us to the level of reflective knowledge. I offer a sketch of an alternative approach, linking knowledge and justification with epistemic accountability and responsible belief-management, which casts doubt on the idea that "animal" knowledge is knowledge properly so-called. However, it turns out that this approach is close in spirit to Sosa's. I suggest that the differences between us may rest on a disagreement over the possibility of providing a direct answer to the Pyrrhonian challenge. (shrink)

A distinguished team of fourteen European philosophers addresses the current debates on internalism versus externalism in the philosophy of language and mind. The main objective of the volume is to demonstrate the philosophical significance and fruitfulness of the internalism/externalism debate on a wide range of issues, and to do so in a manner which is sophisticated yet accessible to non-specialists. The issues authors deal with include linguistic deference, interpreting classical externalist thought-experiments by Putnam and Burge, the nature of (...) Wittgenstein's externalism, apriority, intersubjective externalism, and object-dependence of thought and temporal externalism. Some of the contributors try to strike a balance between internalist and externalist position. (shrink)

Presents central issues pertaining to internalism vs. externalism and foundationalism vs. virtue epistemology in the form of a philosophical debate.

An argument that nativism is true and important but mysterious, examining the particular case of ideas of sensible qualities. In this book, Colin McGinn presents a concise, clear, and compelling argument that the origins of knowledge are innate—that nativism, not empiricism, is correct in its theory of how concepts are acquired. McGinn considers the particular case of sensible qualities—ideas of color, shape, taste, and so on. He argues that these, which he once regarded as the strongest case for (...) the empiricist position, are in fact not well explained by the empiricist account that they derive from interactions with external objects. Rather, he contends, ideas of sensible qualities offer the strongest case for the nativist position—that a large range of our knowledge is inborn, not acquired through the senses. Yet, McGinn cautions, how this can be is deeply problematic; we have no good theories about how innate knowledge is possible. Innate knowledge is a mystery, though a fact. McGinn describes the traditional debate between empiricism and nativism; offers an array of arguments against empiricism; constructs an argument in favor of nativism; and considers the philosophical consequences of adopting the nativist position, discussing perception, the mind–body problem, the unconscious, metaphysics, and epistemology.

In recent decades, epistemology has witnessed the development and growth of externalist theories of knowledge and justification. Critics of externalism have focused a bright spotlight on this approach and judged it unsuitable for realizing the true and original goals of epistemology. Their own favored approach, internalism, is defended as a preferable approach to the traditional concept of epistemic justification. I shall turn the spotlight toward internalism and its most prominent rationale, revealing fundamental problems at the core of (...) internalism and challenging the viability of its most popular rationale. Although particular internalist theories such as (internalist) foundationalism and coherentism will occasionally be discussed, those specific theories are not my primary concern. The principal concern is rather the general architecture of internalism, and the attempt to justify this architecture by appeal to a certain conception of what justification consists in. (shrink)

The subject of this book is an epistemological consideration concerning the nature of knowledge. But other than the most essays on the subject of knowledge, here I am going to deal with a largely overlooked account to try to find an answer to the question of knowledge. This is the mental state account of knowledge. Or to put it into the main question: is knowledge a mental state? Now, the question is: Why is the epistemic (...) thinking of Cook Wilson, Prichard and Austin afflicted with such ignorance in contemporary epistemic discussions? The answer is: an unreflected Platonian heritage during 2000 years of epistemic thinking - a notion which is similar to a point Hetherington has called "epistemic absolutism". So my main conclusion here is: the JTB thesis (knowledge is some aspect of justified true belief) is insufficient in order to give an account of the nature of knowledge. A consequence from this is: all the epistemic theories which are dealing with the JTB thesis are based on deficient assumptions. Hence their results - notably the well-known externalism/internalism debate - are insufficient, too. So, there is a need for a new theory of knowledge based on the MS thesis. (shrink)

Introductions to the theory of knowledge are plentiful, but none introduce students to the most recent debates that exercise contemporary philosophers. Ian Evans and Nicholas D. Smith aim to change that. Their book guides the reader through the standard theories of knowledge while simultaneously using these as a springboard to introduce current debates. Each chapter concludes with a “Current Trends” section pointing the reader to the best literature dominating current philosophical discussion. These include: the puzzle of reasonable (...) disagreement; the so-called “problem of easy knowledge”; the intellectual virtues; and new theories in the philosophy of language relating to knowledge. Chapters include discussions of skepticism, the truth condition, belief and acceptance, justification, internalism versus externalism, epistemic evaluation, and epistemic contextualism. Evans and Smith do not merely offer a review of existing theories and debates; they also offer a novel theory that takes seriously the claim that knowledge is not unique to humans. Surveying current scientific literature in animal ethology, they discover surprising sophistication and diversity in non-human cognition. In their final analysis the authors provide a unified account of knowledge that manages to respect and explain this diversity. They argue that animals know when they make appropriate use of the cognitive processes available to animals of that kind, in environments within which those processes are veridically well-adapted. _Knowledge_ is a lively and accessible volume, ideal for undergraduate and post-graduate students. It is also set to spark debate among scholars for its novel approaches to traditional topics and its thoroughgoing commitment to naturalism. (shrink)

In the paper, I distinguish the bottom-up strategy and the intentional stance strategy of analyzing group intentional states, and show that the thesis of distributed group subject of knowledge could be accommodated by either of them. Moreover, I argue that when combined with virtue reliabilism the thesis satisfactorily explains the phenomenon of group knowledge. To justify my argument, in the second part of the paper, I distinguish two accounts of justification pointing to conditions of group knowledge. The (...) first, which I call the belief-centered approach to group intentional states, determines the concept of group belief and group justificatory reason. The second, the process-centered approach represented by S. Orestis Palermos, employs the theory of virtue reliabilism and focuses on the group knowledge-conducive process. In the paper, I argue in favor of the latter as the internalism associated with the former appears to lack sufficient explanatory power. The theory of virtue epistemology runs into considerable difficulties when trying to deal with an extended epistemic subject composed of one individual and her cognitive artifact. In the two last parts of the paper, I consider the most important difficulties and argue that these obstacles are overcome once one adopts an approach combining virtue epistemology and the thesis of distributed group epistemic subject.

While there is general agreement about the list of epistemic virtues, there has been much controversy over what it is to be an epistemic virtue. Three competing theories have been offered: evaluational externalism, evaluational internalism, and mixed theories. A major problem with internalism, the focus of this paper, is that it disconnects the value of epistemic virtue from actual success in the real world (the Disconnection Problem). Relying on a novel thesis about the relation of “trying” and “exercise (...) of virtue,” James Montmarquet (1993; 2000) has offered, to my knowledge, the only solution to this problem. In this paper, I evaluate this solution by deriving from it an important implication and arguing that, if examined in the light of the recent work on self-control in philosophy and psychology, this implication proves problematic. I conclude by drawing a general lesson about the prospects of internalism and suggesting that in the absence of a satisfactory solution to the disconnection problem, externalism and mixed theories become more attractive.

The generality problem is usually taken to arise only for externalist theories of knowledge or justification. In this paper, first, I argue that even internalist theories run afoul of a variant of the generality problem. This is because S may have multiple pieces of evidence concerning the reliability of the token process by which S forms the belief in question, and they determine the degree of Sʼs internalist justification differently. Second, I offer a solution to the generality problem for (...) internalist theories: Sʼs practical reason rather than epistemic reason picks out a piece of evidence concerning reliability as relevant.

Although the fallible/infallible distinction in the theory of knowledge has traditionally been upheld by most epistemologists, almost all contemporary theories of knowledge claim to be fallibilist. Fallibilists have, however, been forced to accommodate knowledge of necessary truths. This has proved to be a daunting task, not least because there is as yet no consensus on how the fallible/infallible divide is to be understood. In this article, after examining and rejecting a number of representative accounts of the (...) notion of fallible knowledge, I argue that the main problems with these accounts actually stem from the very coherence of that notion. I then claim that the distinction is best understood in terms of the externalist/internalist conceptions of knowledge. Finally, I seek to garner some independent support for the proposal by highlighting some of its consequences, including its surprising bearing on certain recent and seemingly distant controversies involving issues in epistemology and philosophy of mind.

In Michael Ruse's recent publications, such as Taking Darwin Seriously (1998) and Evolutionary Naturalism (1995), he has advocated a certain sort of evolutionary epistemology and has argued that it implies a rejection of metaphysical realism (MR) in favor of a position that he calls “internal realism” (IR). Additionally, he has maintained that, insofar as his evolutionary epistemology implies a rejection of MR in favor of IR, it escapes the kind of argument against naturalism that Alvin Plantinga makes in his Warrant (...) and Proper Function (1993). In this article I explain the relevant views and arguments of Ruse and Plantinga, and I critically engage with Ruse's views, arguing that (1) his case for rejecting MR has no essential connection to evolutionary considerations; (2) his case for rejecting MR depends upon internalist assumptions about the nature of knowledge that are in need of some kind of defense; and (3) given his implicit internalism and his commitment to IR, his argument for rejecting MR can be used against his IR.

While recent debates over content externalism have been mainly concerned with whether it undermines the traditional thesis of privileged self‐knowledge, little attention has been paid to what bearing content externalism has on such important controversies as the internalism/externalism debate in epistemology. With a few exceptions, the question has either been treated as a side issue in discussions concerning the implications of content externalism, or has been dealt with in a cursory way in debates over the internalism/externalism distinction (...) in justification theory. In this paper, I begin by considering some of the arguments that have sought to address the question, focusing mainly on Boghossian's pioneering attempt in bringing the issue to the fore.1 It will be argued that Boghossian's attempt to exploit the alleged non‐inferentiality of self‐knowledge to show that content externalism and justification internalism are incompatible fails.In the course of this examination, I consider and reject as inadequate some recent responses to Boghossian's argument . I then turn to evaluating Chase's own proposed argument to show how content externalism can be brought to bear on the internalism/externalism debate in epistemology, and find it wanting. Finally, having discussed BonJour's terse remarks in this connection,3 I set out to present, what I take to be, the strongest argument for the incompatibility of content externalism and justification internalism while highlighting the controversial character of one of its main premises. Let us, however, begin by drawing the contours of the debate. (shrink)

What does it take for a positive epistemic status to obtain? I argue throughout my thesis that if a positive epistemic status obtains, this is not a brute fact. Instead, if for example a belief is justified, it is justified in virtue of some further condition(s) obtaining. A fundamental topic in epistemology is the question of what sorts of factors can be relevant to determining the positive epistemic status of belief. Epistemic Internalism holds that these factors must be “internal” (...) (in a sense that needs to be specified). Epistemic Externalism is the denial of internalism. My thesis is an explanation and defense of an internalist theory of epistemic justification. -/- The central claim of my thesis is that something is “internal” in this sense only if it is, or can easily be, the object of the agent’s conscious awareness. By considering key cases, I show that without an awareness requirement on justification, the subject cannot avoid what I call the Subject’s Perspective Objection. In developing this objection I examine and respond to an argument against the awareness requirement which claims that such awareness either leads to a vicious regress of requiring higher order beliefs of increasing complexity (if any beliefs are to be justified), or else requiring such awareness is unmotivated. This regress is generated because it is assumed that the relevant kind of awareness must be doxastic. My solution invokes what I call ‘strong non-doxastic awareness’ that grounds non-inferential justification and thereby avoids this dilemma, while meeting the Subject’s Perspective Objection. -/- I also argue that external factors, such as the reliability (actual or conditional) of the mechanism supporting the belief, are not necessary for justification. I argue for this conclusion by comparing what constitutes justified belief in the actual world with one’s counterpart in a ‘demon world’. I argue that this intuition, correctly interpreted, counts in favour of internalism. As I explain, many philosophers moved by arguments presented by externalists about mental content deny that such a case is possible. In opposition I argue that the awareness requirement remains substantially unaffected, no matter which view of content turns out to be correct. What is key is that the two worlds are completely subjectively indistinguishable from each other for those who inhabit them in all the ways of which they are consciously aware. -/- If neither the obtaining of truth nor reliability is necessary for epistemic justification, what makes justification genuinely epistemic? In the final chapter I argue against recent work that assimilates justification with knowledge, as well as for a positive account of the truth connection. As to the former question, I defend the orthodoxy that they are distinct epistemic statuses; as to the latter, I argue that the connection between justification and truth is conceptual. That is, epistemic justification is epistemic because it turns on evidence; evidence is epistemic because it is conceptually linked with truth. Epistemic justification, therefore, is conceptually linked with the truth (via evidence), which is what makes it distinctively epistemic. -/- In short, this thesis is an explanation and defense of an internalist theory of epistemic justification. The central claim of the thesis is that something is “internal” in this sense only if it is, or can easily be, the object of the agent’s conscious awareness. I argue that conscious awareness is a necessary condition of epistemic justification obtaining, and that factors external to consciousness play no justificatory role. (shrink)

This article explores the explanation of incommensurable theories as alternative conceptual schemes based on different categorical or taxonomic structures. The concept of incommensurability, which is a cornerstone of the late philosophy of Thomas Kuhn, is elucidated, reflecting his approach to avoid assessing the history of science in terms of the truth and falsity of scientific paradigms. It is shown how Kuhn has combined Frege – Russell’s descriptivist semantics and the causal theory of reference by Hilary Putnam and Saul Kripke. (...) His version of semantics consists in redefinition of natural kinds in terms of neuropsychology, in substantiating mentalist and internalist perspective on language. Kuhn’s philosophical position is identified as post-Darwinian Kantianism. It is expressed not in a priori nature of knowledge, but in its determination by conceptual schemes and sociocultural relativity. Despite the fact that the incommensurable terms seem to occur in the history of knowledge, incommensurability remains not the clearest and most consistent way of thinking on the history of science. Kuhn repeatedly refined his views on incommensurability, ultimately aligning it more closely with alternative classifications of objects serving as a framework for subsequent theories. Natural kind concepts, like taxonomic units, distribute the perceived objects into hierarchies reflecting structures of external world. On the one hand, kinds differentiate objectively existing objects into groups. On the other hand, kind terms are both mental modules and cultural constructs that are used to organize the experience of language speakers, identify objects, and provide the basis for group beliefs. Kuhn posits that the development of scientific theories constitutes an evolution of conceptual schemes characterized by disparities and incommensurability. (shrink)

Without a doubt, one of the main reasons Platonsim remains such a strong contender in the Foundations of Mathematics debate is because of the prima facie plausibility of the claim that objectivity needs objects. It seems like nothing else but the existence of external referents for the terms of our mathematical theories and calculations can guarantee the objectivity of our mathematical knowledge. The reason why Frege – and most Platonists ever since – could not adhere to the idea that (...) mathematical objects were mental, conventional or in any other way dependent on our faculties, will or other historical contingencies was that objects whose properties of existence depended on such contingencies could not warrant the objectivity required for scientific knowledge. This idea gained currency in the second half of the 19th Century and remains current for the most part today. However, it was not always like that. Objectivity, after all, has a history, and according to its historians (Daston 2001), the view that scientific knowledge need be objective is a fairly recent one. Up until mid-19th Century, science was not so much concerned with objectivity, as it was concerned with truth. Before the rise of the modern university and the professional scientist, science had the discovery of truths as its ultimate goal. In contrast, modern science now aims at the production and acquisition of objective knowledge. The difference might seem.. (shrink)

Although the fallible/infallible distinction in the theory of knowledge has traditionally been upheld by most epistemologists, almost all contemporary theories of knowledge claim to be fallibilist. Fallibilists have, however, been forced to accommodate knowledge of necessary truths. This has proved to be a daunting task, not least because there is as yet no consensus on how the fallible/infallible divide is to be understood. In this article, after examining and rejecting a number of representative accounts of the (...) notion of fallible knowledge, I argue that the main problems with these accounts actually stem from the very coherence of that notion. I then claim that the distinction is best understood in terms of the externalist/internalist conceptions of knowledge. Finally, I seek to garner some independent support for the proposal by highlighting some of its consequences, including its surprising bearing on certain recent and seemingly distant controversies involving issues in epistemology and philosophy of mind.

This book explores the idea that self-knowledge comes in many varieties. We “know ourselves” through many different methods, depending on whether we attend to our propositional attitudes, our perceptions, sensations or emotions. Furthermore, sometimes what we call “self-knowledge” is not the result of any substantial cognitive achievement and the characteristic authority we grant to our psychological self-ascription is a conceptual necessity, redeemed by unravelling the structure of several interlocking concepts. This book critically assesses the main contemporary positions held (...) on the epistemology of self-knowledge. These include robust epistemic accounts such as inner sense views and theory-theories; weak epistemic accounts such as transparency theories and rational internalism and externalism; as well as expressivist and constitutivist approaches. The author offers an innovative “pluralist” position on self-knowledge, emphasizing the complexity of the phenomenon and its resistance to any “monistic” treatment, to pose new and intriguing philosophical challenges.

I attempt to persuade the reader that externalism admits of no plausible interpretation. I argue that reliability is a concept with very different contours from epistemic justification, and that attempts to explicate justification in terms of reliability must fail. I address several other forms of externalism, and also mixed forms of justification. I then argue that externalist theories of justification cannot close the gap between mere true belief and knowledge. I suggest that a fourth condition on knowledge is (...) required, regardless of whether justification is internalist or externalist. I argue that with such a fourth condition a strong internalist theory of justification is adequate to the task that remains in making true belief knowledge. Additionally, strong internalism is more satisfying to our intuitions than externalism and mixed forms of justification. (shrink)

In Knowledge and Belief, Frederick Schmitt explores the nature and value of knowledge and justified belief through an examination of the dispute between epistemological internalism and externalism. Knowledge and justified belief are naturally viewed as belief of a sort likely to be true--an externalist view. It is also intuitive, however, to view them as an internal matter; justification must be accessible to the subject or constituted by the subject's epistemic perspective. The author argues against the view (...) that internalism is the historically dominant epistemology by examining closely the epistemological principles that underlie the treatment of skepticism in Plato, the Academic and Pyrrhonian skeptics, Descartes and Hume. Schmitt develops a sustained, detailed argument against many forms of internalism in favor of a reliabilist/externalist epistemology. His version of reliabilism, though strictly externalist, accommodates and explains the most durable intuitions alleged to support internalism. Knowledge and Belief assumes no knowledge of epistemology or its history. Readers of philosophy will find this an excellent introduction to ancient and modern epistemology; this systematic study of the internalist and externalist debate is the first of its kind. (shrink)

Gertler argues that, in some introspective judgments about experience, phenomenal reality intersects with one's grasp of that reality to the effect that one can have knowledge by acquaintance. This new version of the acquaintance theory depends on the idea that some introspective judgments about experience can be justified by the fact that the phenomenal property of an experience is a component of the introspective judgment about the experience. The goal of this paper is to show that even this (...) most promising version of the acquaintance theory is not successful. For this goal, in particular, I argue that even if we grant that, in the relevant cases, the phenomenal property of an experience is a component of an introspective judgment, this fact can hardly play the epistemic role that Gertler envisions. I establish this on the basis of two internalist requirements for reasons, namely, the evaluability condition and the endorsement condition. On the former condition, a reason for justifying a judgment must be the kind of thing that can be evaluated as correct or incorrect. And on the latter condition, having a reason for justifying a judgment requires that the subject endorse the reason as correct. (shrink)

HELMU'r HOLZHEY Universityof Zurich Robert J. Richards. Darwin and the Emergenceof Evolutionary TheoriesofMind and Behav- /or. Science and Its Conceptual Foundations Series. (...) Chicago: The University of Chicago Press, 1987. Pp. xvii + 7oo. $34.95. This fascinating book operates at two levels, possibly three. At the most straightforward level, it is a history of science, telling the tale of the fate of evolutionary ideas as they have been applied to mind and behavior during the past two centuries, with special emphasis on the nineteenth century. At another level, Richards is acting qua philosopher, for he thinks the story he has to tell has important implications for philosophy. In particular, he thinks the people he discusses show the way to compelling theories of evolutionary epistemology and evolutionary ethics. To this end he attaches two philosophical appendices to his book, articulating and defending his philosophical claims. Then, at perhaps a third level, Richards uses his historical narrative as a case study (and possibly an exemplar) for his philosophy, especially his epistemology, trying to justify and illustrate his position. Let me take these levels in turn, briefly. First, we have the history. Anybody who knows anything at all about the history of science will know that the subject is clogged with overproduction and overinterpretation around a few key figures. Chief among these is Charles Darwin, and if ever anyone writes anything again on his discovery of natural selection, I for one will scream. What I have long suspected-- and what Richards shows in full detail--is that, because of their tunnel vision, the historians of science thereby ignore huge fertile areas, which go untouched. And the paradox is that the narrow perspective means that important aspects of those overdiscussed figures go unanalyzed! Certainly, Richards plows virgin territories, and thereby throws new light on many important figures in biology, psychology, and philosophy--not the least of which is Darwin himself. Richards starts in the eighteenth century with the first growths of evolutionary thought, showing that from the beginning thinkers recognized that humankind had to be part of the problem, and that this meant (in particular) human thought and behavior. I was glad to see a full discussion of Charles Darwin's grandfather, Erasmus Darwin. We are now starting to realize how he merits interest in his own right, not just as a curious anticipation of his more famous grandson. Moving forward, Richards shows how Erasmus Darwin struggled constantly with the problem of the human mind, as did Frenchmen like Lamarck. These and other thinkers were all known to s See H. Holzhey, "Neukandanismus," in HistorischesWOrterbuchderPhilosopfiie,vol.6 (1984), column 747ft. BOOK REVIEWS 145 Charles Darwin, and a significant part of Richards's discussion is devoted to showing just how much of Charles Darwin's thought on mind and behavior was built out of the work of others--with his own distinctive twists. Richards emphasizes, and I am sure he is right here, that natural theology was crucial to the development of Charles Darwin's thinking. It was not, as many critics have claimed, a case of Darwin throwing off religion and then taking up evolution. Rather, he has led to his evolution through his religion. Richards is almost unique among twentieth-century thinkers in finding virtue in the work of Herbert Spencer. I am still not convinced that Spencer was other than a tedious Victorian chauvinist. But no doubt I will not be the only scholar who is happy to have a Spencer apologist against whom one can test one's critical opinions. To be commended without reservation, however, is Richards's detailed analysis of the psychobiological thinking of William James. Richards delicately balances his knowledge of James's own psychological states (including facts still suppressed) with conceptual analysis of James's scientific claims. I do not know if this counts as "externalist" or "internalist " history of science, but it certainly shows that knowledge... (shrink)

Goodman and Elgin have recommended a reconception of philosophy. A central part of their recommendation is to replace knowledge by understanding. According to Elgin, some important internalist and externalist theories of knowledge favor a sort of undesirable cognitive minimalism. Against Elgin I try to show how the challenge of cognitive minimalism can be met. Goodman and Elgin claim that defeat and confusion are built into the concept of knowledge. They demand either its revision or its replacement or (...) its supplement. I show that these are three very different options. While agreeing with the view that there may be good reasons for some revisions and supplements, I strongly disagree with Elgin and Goodman's replacement thesis. (shrink)
