This anthology brings together ten papers which have defined and advanced the debate between internalism and externalism in epistemology.

Although David Hume is no match for Immanuel Kant in terms of opaque writing, his overall philosophy is not without interpretive difficulties. Earlier this century, many philosophers read Hume as the precursor to logical positivism. Of course, the concluding words of his Enquiry Concerning Human Understanding added fuel to these flames; but with the downfall of positivism, this reading of Hume has virtually disappeared. Today, interpretations of Hume fall into two main camps: the naturalistic camp and the sceptical camp. Roughly (...) speaking, naturalistic interpreters of Hume see him as attempting to employ the methods of the natural sciences in studying human subjects while sceptical interpreters read Hume as denying that we have any knowledge. In this article I want to shed some light on this controversy in an indirect way: namely, by trying to classify Hume’s epistemology as internalist or externalist. Although this internalism/externalism debate has erupted only recently in epistemology, it should be constructive in carving up the logical space of certain epistemological positions. With this background in place, we can not only see how to categorize Hume, but also discern some of the ramifications for Hume’s epistemology when he affirms theses that place him in these categories. To anticipate a bit, I will argue that the internalist aspects of Hume’s epistemology lend great credence to the sceptical interpretation. (shrink)

Absolute velocities in Newtonian mechanics are commonly regarded as unmeasurable. Roberts (Br J Philos Sci 59(2):143–168, 2008) provides a justification for this thesis which appeals to the observational indistinguishability of boost-related models of Newtonian mechanics. Middleton and Murgueitio Ramírez (Australas J Philos, 2020) criticise his argumentation by pointing out that his analysis of the notion of measurement is too restrictive, and that, under a weaker analysis (based on counterfactuals), absolute velocities are measurable. Jacobs (Australas J Philos, 2020) opposes their view, (...) arguing that, on a properly formulated counterfactual-based account of measurement, absolute velocities are unmeasurable. However, in his argument, observational indistinguishability plays no role, even though, intuitively, it is very relevant for the issue of (un)measurability. This paper’s aim is to bring observational indistinguishability back to this discussion. I build upon the observation that there is an analogy between possible views on knowledge and justification on the one hand, and on measurement on the other. In particular, I explore the distinction between externalist and internalist approaches. Counterfactual-based accounts are all externalist, whereas the observational indistinguishability of boost-related models becomes relevant if we are interested in an internalist concept of measurement.

In general, epistemic internalists hold that an individual’s justification for a belief is exhausted by her reflectively accessible reasons for thinking that the contents of her beliefs are true. Applying this to the epistemology of testimony, a hearer’s justification for beliefs acquired through testimony is exhausted by her reflectively accessible reasons to think that the contents of the speaker’s testimony is true. A consequence of internalism is that subjects that are alike with respect to their reflectively accessible reasons are (...) alike with respect to what they have justification to believe. Testimony should be thought no different: hearers that are alike with respect to reflectively accessible reasons to think that a speaker’s testimony is true are alike with respect to their justification for beliefs based upon that testimony. But it has been recently argued that this view faces powerful counterexamples. So the central question is this: assuming that a hearer can acquire justification to believe a proposition through the testimony of a speaker, can epistemic internalism provide the resources to explain how such justification is possible? My aim in this paper is to address these counterexamples, and in so doing, defend epistemic internalist accounts of testimony. (shrink)

The paper highlights how a popular version of epistemological disjunctivism labors under a kind of 'internalist challenge'—a challenge that seems to have gone largely unacknowledged by disjunctivists. This is the challenge to vindicate the supposed 'internalist insight' that disjunctivists claim their view does well to protect. The paper argues that if we advance disjunctivism within a context that recognizes a distinction between merely functional and judgmental belief, we get a view that easily overcomes the internalist challenge.

Internalism restricts justifiers to what is "within" the subject. two main forms of internalism are (1) perspectival internalism (pi), which restricts justifiers to what the subject knows or justifiably believes, and (2) access internalism (ai), which restricts justifiers to what is directly accessible to the subject. the two forms are analyzed and interrelated, and the grounds for each are examined. it is concluded that although pi is both unacceptable and without adequate support, a modest form of (...) ai might be defended.

Internalism and Externalism in Semantics and Epistemology presents eleven specially written essays exploring these debates in metaphysics and epistemology and ...

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)

Is the nature of testimonial warrant epistemically internalist or externalist? I will argue that the question should be answered ‘yes!’ The disjunction is not exclusive. Rather, a testimonial belief may possess epistemically internalist warrant—justification—as well as epistemically externalist warrant—entitlement. I use the label ‘pluralism’ to denote the view that there are both internalist and externalist species of genuinely epistemic warrant and argue for pluralism in the epistemology of testimony.

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)

The dialogue between internalists who maintain a belief is a case of knowledge when that which justifies the belief is within the agent's first-person perspective and externalists who maintain epistemic justification can be in part, or entirely, outside the agent's first-person perspective has been part of the epistemological literature for some time with one side usually attempting to show how the other side is mistaken. Edward Craig argues the internalist/externalist debate is flawed from the outset. Specifically, both internalism (...) and externalism should be incorporated into the correct analysis of knowledge once we revamp that project. The epistemological project, according to Craig, is a practical explication of what both our epistemological practices and the concept of knowledge do for us. My purpose here is to evaluate this proposal, as well as Ram Neta's attempt to generalize this proposal to cover all epistemic appraisals, in light of the internalism/externalism debate. I argue the Craig/Neta proposal does not actually 'solve' the internalism/externalism debate, but rather pushes it back a level or assumes that one side is correct; hence, the Craig/Neta proposal is not an adequate 'solution' to the internalism/externalism debate.

This paper is an attempt at exploring the possibility of reconciling the two interpretations of biolinguistics which have been recently projected by Koster(Biolinguistics 3(1):61–92, 2009). The two interpretations—trivial and nontrivial—can be roughly construed as non-internalist and internalist conceptions of biolinguistics respectively. The internalist approach boils down to a conception of language where language as a mental grammar in the form of I-language grows and functions like a biological organ. On the other hand, under such a construal consistent with Koster’s (Biolinguistics (...) 3(1):61-92, 2009), the non-internalist version does not necessarily have to be externalist in nature; rather it is a matter of mutual reinforcement of biology and culture under the rubric of a co-evolutionary dynamics. Here it will be argued that the apparent dichotomy between these two conceptions of biolinguistics can perhaps be resolved if we have a richer synthesis that accounts for both internalism and non-internalism.

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.

Much has been written about Kemp Smith's famous problem regarding the tension between Hume's naturalism and his scepticism. However, most commentators have focused their attention on the Treatise; those who address the Enquiry often take it to express essentially the same message as the Treatise. When Hume's scepticism in the Enquiry has been investigated in its own right, commentators have tended to focus on Hume's inductive scepticism in Sections 4 and 5. All in all, it seems that Section 12 has (...) been unduly neglected. This paper seeks to address Kemp Smith's problem from the standpoint of Hume's treatment of scepticism in EHU 12, and finds an interesting internalist account that makes sense both of Hume's discussion in EHU 12, and his aims in the Enquiry as a whole. Moreover, it is one that is of substantive philosophical interest, having intriguing parallels to contemporary epistemological accounts. (shrink)

Do Descartes, Locke, and Hume have an internalist or externalist view of epistemic justification? Internalism is, roughly, the view that a belief that p is justified by a mental state, such as the awareness of evidence. By contrast, externalism is, roughly, the view that a belief that p is justified by facts about the belief-forming process, such as the reliability of the belief-forming process. I argue that they all think that the awareness of evidence is required for justification, but (...) none of them think that the awareness of evidence alone is sufficient for justification. Similarly, I argue that they all think that reliability of the belief-forming process is required for justification, but none of them think reliability alone is sufficient for justification. So, neither a fully internalist position nor a fully externalist position adequately captures their views of justification; rather, both the supporting evidence and the reliability of the belief-forming process explain why we should hold those beliefs, and hence explain why those beliefs are justified. Thus, they each have a partly internalist, partly externalist view of justification. (shrink)

To what extent are meaning, on the one hand, and knowledge, on the other, determined by aspects of the 'outside world'? Internalism and Externalism in Semantics and Epistemology presents twelve specially written essays exploring these debates in metaphysics and epistemology and the connections between them. In so doing, it examines how issues connected with the nature of mind and language bear on issues about the nature of knowledge and justification. Topics discussed include the compatibility of semantic externalism and epistemic (...) internalism, the variety of internalist and externalist positions, semantic externalism's implications for the epistemology of reasoning and reflection, and the possibility of arguments from the theory of mental content to the theory of epistemic justification.

This paper addresses the meta-epistemological dispute over the basis of epistemic evaluation from the standpoint of meliorative epistemology. Meliorative epistemology aims at guiding our epistemic practice to better results, and it comprises two levels of epistemic evaluation. At the social level (meliorative social epistemology) appropriate experts conduct evaluation for the community, so that epistemic evaluation is externalist since each epistemic subject in the community need not have access to the basis of the experts' evaluation. While at the personal level (...) (meliorative personal epistemology) epistemic evaluation is internalist since each member of the community must evaluate the reliability of the (apparent) experts from the first-person perspective. I argue that evaluation at the social level should be the primary focus of meliorative epistemology since meliorative personal epistemology does not provide informative epistemic norms. It is then pointed out that epistemic evaluation at the social level can be considered internalist in the extended sense (social internalism) in that every component of the evaluation needs to be recognized by some members of the community at some points. As a result, some familiar problems of internalist epistemology, such as regress and circularity of epistemic support, carry over to meliorative social epistemology. (shrink)

In The Epistemic Role of Consciousness (2019), Declan Smithies has carried out a thorough radical internalist programme. Along the way he compares and contrasts many different views, including a group he calls “radical externalism.” From the labels, it might seem that radical internalism and radical externalism must be very different in their core commitments. In this short note, I will single out a version of radical externalism – factivism, more specifically John McDowell’s version (1994, 1995, 2011) – and argue (...) that actually this version has many similarities with Smithies radical internalism. Where there are differences, they do not obviously lie at the internalist/externalist juncture. The main point of this comparison is that philosophical positions that seem very different can share much common ground, and in seeing this one can be in a better position to understand the crucial points of disagreement.

Internalism holds that epistemic justification is determined by what is internal to the mind, not by facts about the mind-independent world. This paper introduces and defends a new kind of internalism that is rooted in rationalist ideas that have been neglected in recent epistemology, despite inspiring internalist projects in cognitive science. Ignoring rationalist insights has, I argue, damaged the prospects for internalism, by needlessly saddling internalists with empiricist burdens. Internalists can refuse these burdens by accepting a better (...) philosophy of mind. Rather than looking to 17th century rationalists, I look to Kant, and especially his idea that normativity is grounded in the constitution of agency and mind. A Kantian approach can avoid stock objections to internalism, I argue, and can also capture all the alleged benefits of externalism. The paper is structured as follows. In §2, I get back to basics and consider more ways to satisfy the core internalist template than have become standard. I draw attention to rationalist insights about how normativity could be grounded in the constitution of mind, and hypothesize that if internalism respects these insights, some problems disappear. I develop this hypothesis in §3 with a Kantian view. I further defend this view in §4. I conclude in §5 by explaining why Kantian internalism answers the latest challenges to internalism. (shrink)

I point out that internalist conceptions of belief that have become outmoded in the philosophy of mind are still current in epistemology (or at any rate they were in 2003). I explore the consequences of bringing epistemology up to speed with a more contemporary conception of belief.

In sec. 1.1 I emphasize the meliorative purpose of epistemology, and I characterize Goldman's epistemology as reliabilistic, cognitive, social, and meliorative. In sec. 1.2 I point out that Goldman's weak notion of knowledge is in conflict with our ordinary usage of 'knowledge'. In sec. 2 I argue for an externalist-internalist hybrid conception of justification which adds reliability-indicators to externalist knowledge. Reliability-indicators produce a veritistic surplus value for the social spread of knowledge. In sec. 3 I analyze some particular meliorative rules (...) which have been proposed by Goldman. I prove that obedience to the rule of maximally specific evidence increases expected veritistic value (sec. 3.1), and I argue that rule-circular arguments are epistemically worthless (sec. 3.2). In the final sec. 3.3 I report a non-circular justification of meta-induction which has been developed elsewhere. (shrink)

Mylan Engel, Jr. has proposed a straightforward and attractive explanation of the internalism-externalism controversy (IEC) in contemporary epistemology. Engel's explanation posits that there are two distinct kinds of epistemic justification, and the IEC has arisen because epistemologists have inadvertently overlooked the fact that they are not all concerned with the same subject matter (internalists are concerned with one kind of epistemic justification while externalists are concerned with another kind). In this paper, I will explain two difficulties with Engel's proposed (...) explanation. The first difficulty concerns the claim that there are two kinds of epistemic justification. The second difficulty concerns whether Engel's proposed explanation is adequate to explain internalist concerns. (shrink)

According to epistemological internalism, the rationality of a belief supervenes purely on "internal facts" about the thinker's mind. But what are "internal facts"? Why does the rationality of a belief supervene on them? The standard answers are unacceptable. This paper proposes new answers. "Internal facts" are facts about the thinker's nonfactive mental states. The rationality of a belief supervenes on such internal facts because we need rules of belief revision that we can follow directly, not by means of (...) following any other rules, and the proximate explanation of any belief revision always consists of such internal facts.

This paper articulates and defends a novel version of internalist evidentialism which employs dispositions to account for the relation of evidentialsupport. In section one, I explain internalist evidentialist views generally, highlighting the way in which the relation of evidential support stands at the heart of these views. I then discuss two leading ways in which evidential support has been understood by evidentialists, and argue that an account of support which employs what I call epistemic dispositions remedies difficulties arguably faced by (...) these two leading accounts. In sections two and three, I turn to advantages that my dispositionalist account of evidential support offers evidentialists beyond its remedying apparent difficulties with rival accounts of support. In section two, I show that the account is well-suited to help the evidentialist respond to the problem of forgotten evidence. And, in section three, I show that adopting my dispositional account makes possible an attractive and natural synthesis of evidentialism and virtue epistemology which is superior to the leading contemporary synthesis of these views.

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 current discussions on African epistemology, the issue of justification of beliefs has mainly been considered from an externalist perspective, such that justification is described as achievable merely through the means of empirical verification and social context of discourse. However, this results in a knowledge-gap since both internalist and externalist perspectives are needed to arrive at a holistic notion of epistemic justification. Consequently, the objective of this article is to fill this gap by employing the methods of conceptual and critical (...) analysis to attempt an internalist interpretation of epistemic justification in the quest for a more balanced view of African epistemology.

The internalism /externalism debate is of interest in epistemology since it addresses one of the most fundamental questions in the discipline: what is the basic nature of knowledge and epistemic justification? It is generally held that if a positive epistemic status obtains, this is not a brute fact. Rather if a belief is, for example, justified, it is justified in virtue of some further condition obtaining. What has been called epistemic internalism holds, as the label suggests, is that (...) all the relevant factors that determine justification must be “internal”. Epistemic externalism is the denial of internalism. Epistemic internalism about justification is the subject of this article. After introducing the central intuitive considerations that have tended to motivate internalism, this paper will explore different ways of construing the internalist position. In addition to classical formulations, more recent formulations will be discussed, concluding with a discussion of an emerging position known as “Epistemological Disjunctivism”, which its advocates claim preserves the most important features of more traditional forms of internalism, while avoiding their difficulties. Epistemological Disjunctivism is particularly worthy of attention since if true, it promises to bridge internalist and externalist epistemologies, bringing a rapprochement to two sides of what may otherwise appear a deep and intractable debate about the fundamental nature of epistemology.

One of the arguments for active externalism (also known as the extended mind thesis) is that if a process counts as cognitive when it is performed in the head, it should also count as cognitive when it is performed in the world. Consequently, mind extends into the world. I argue for a corollary: We sometimes perform actions in our heads that we usually perform in the world, so that the world leaks into the mind. I call this internalism. (...) class='Hi'>Internalism has epistemological implications: If a process gives us an empirical discovery when it is performed in the world, it will also give us an empirical discovery when it is performed in the head. I look at a simple example that highlights this implication. I then explore the relation between internalism and active externalism in more detail and conclude by comparing internalism with mental modeling. (shrink)

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

Epistemic internalism, by stressing the indispensability of the subject’s perspective, strikes many as plausible at first blush. However, many people have tended to reject the position because certain kinds of beliefs have been thought to pose special problems for epistemic internalism. For example, internalists tend to hold that so long as a justifier is available to the subject either immediately or upon introspection, it can serve to justify beliefs. Many have thought it obvious that no such view can (...) be correct, as it has been alleged that internalism cannot account for the possibility of the justification of beliefs stored in memory. -/- My aim in this paper is to offer a response that explains how memory justification is possible in a way that is consistent with epistemic internalism and an awareness condition on justification. Specifically, I will explore the plausibility of various options open to internalists, including both foundationalist and non-foundationalist approaches to the structure of justification. I intend to show that despite other difficult challenges that epistemic internalism might face, memory belief poses no special problems that the resources of internalism cannot adequately address.

An essential part of the concept of knowledge is the belief that the basic premises for knowledge must be justified. This means that for a knowledgeclaim to be true, there is a need for its justification. In African epistemology, the justification of beliefs and epistemic claims has mostly been considered from an externalist perspective such that justification appears to be one dimensional. Since epistemic claims can be justified using either the internalist or externalist perspective, this paper aims at showing that (...) there are internalism and externalism in African epistemology and that Ifá divination system embodies both the internalist and externalist basis of justification in African epistemology.

Externalism holds, and internalism denies, that the individuation of many of an individual's mental states (e.g., thoughts about the physical world) depends necessarily on relations that individual bears to the physical and/or social environment. Many philosophers, externalists and internalists alike, believe that introspection yields knowledge of the contents of our thoughts that is direct and authoritative. It is not obvious, however, that the metaphysical claims of externalism are compatible with this epistemological thesis. Some (e.g., Burge, 1988; Falvey and (...) Owens (F&O), 1994) have sought to dispel the worry that there is a conflict, though they admit that if such a conflict exists, it spells trouble for externalism (see, e.g., F&O, 1994, p. 108). Boghossian has argued that there is indeed a conflict between externalism and introspective knowledge of content. Surprisingly, however, he also argues that there is a conflict between internalism and introspective knowledge of content. I will defend Boghossian's claim that there is a conflict between externalism and knowledge of content, but criticize his claim that there is a conflict between internalism and knowledge of content.

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 (...) class='Hi'>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)
