This paper defends reductionism about testimonial justification of beliefs against two influential arguments. One is the empirical argument to the effect that the reductionist justification of our trust in testimony is either circular since it relies on testimonial evidence or else there is scarce evidence in support of our trust in testimony. The other is the transcendental argument to the effect that trust in testimony is a prerequisite for the very existence of testimonial evidence since (...) without the presumption of people’s truthfulness we cannot interpret their utterances as testimony with propositional contents. This paper contends that the epistemic subject can interpret utterances as testimony with propositional contents without presupposing the credibility of testimony, and that evidence available to the normal epistemic subject can justify her trust in testimony.

It is often suggested that we are equipped with a set of cognitive tools that help us to filter out unreliable testimony. But are these tools effective? I answer this question in two steps. Firstly, I argue that they are not real-time effective. The process of filtering, which takes place simultaneously with or right after language comprehension, does not prevent a particular hearer on a particular occasion from forming beliefs based on false testimony. Secondly, I argue that they (...) are long-term effective. Some hearers sometimes detect false testimony, which increases speakers’ incentives for honesty and stabilizes the practice of human communication in which deception is risky and costly. In short, filtering prevents us from forming a large number of beliefs based on false testimony, not by turning each of us into a high-functioning polygraph but by turning the social environment of human communication into one in which such polygraphs are not required. Finally, I argue that these considerations support strong anti-reductionism about testimonial entitlement. (shrink)

Reductionism about testimony holds that testimonial warrant or entitlement is just a species of inductive warrant. Anti-Reductionism holds that it is different from inductive but analogous to perceptual or memorial warrant. Perception receives much of its positive epistemic status from being reliably truthconducive in normal conditions. One reason to reject the epistemic analogy is that testimony involves agency – it goes through the will of the speaker – but perception does not. A speaker might (...) always choose to lie or otherwise deliberately mislead. It is argued that the force of this derives (in part) from Libertarianism about agency, and that Libertarianism, if it undermines the Anti-Reductionist explanation of why we are entitled to rely upon testimony, undermines the Reductionist explanation as..

Under which conditions are we epistemically justied to believe that what other people tell us is true? Traditionally, the answer has either been reductionist or anti-reductionist: Either our justication reduces to non-testimonial reasons, or we have a presumptive, though defeasible, right to believe what we are told. However, different cases pull in different directions. Intuitively, someone asking for the time is subject to different epistemic standards than a surgeon consulting a colleague before a dangerous operation. Following this line of (...) thought, this paper develops an account of testimonial justication that captures our reductionist as well as our anti-reductionist intuitions. It is argued that the speaker’s commitment to an epistemic norm, as well as the hearer’s understanding of that norm, gives the hearer a presumptive right to believe what she is told. However, this justication doesn’t apply to situations with high practical risks. Here, the hearer needs reductive reasons to believe that her interlocutor is especially qualied to give her the desired information. (shrink)

This chapter states the contrast between presumptivism about testimonial warrant (often called anti-reductionism) and strict reductionism (associated with Hume) about testimonial warrant. Presumptivism sees an analogy with modest foundationalism about perceptual warrant. Strict reductionism denies this analogy. Two theoretical frameworks for these positions are introduced to better formulate the most popular version of persumptivism, a competence reliabilist account. Seven arguments against presumptivism are then stated and critiqued: (1) The argument from reliability; (2) The (...) argument from reasons; (3) the argument from positive reasons; (4) the argument from negative reasons; (5) the argument from agency; (6) the argument from psychological force; and (7) the argument from gullibility. If presumptivm is false, it is not for any of these arguments. (shrink)

When is a testimony-based belief justified? According to so-called "Anti-Reductionism," the principle that a hearer is prima facie justified to take what another tells them at face value is true. I call this position "Liberal Foundationalism." I call it "liberal" for it is more liberal than "Moderate Foundationalism" that holds that perception-based beliefs are prima facie justified but testimony-based beliefs are not. Liberal Foundationalism has two interpretations: the principle is a contingent empirical truth, or an a (...) priori necessary truth. I call the view that the principle is a priori necessary "Liberal Fundamentalism." This chapter defends Liberal Fundamentalism against objections in the first half, and then in the second half it introduces "Weak Liberal Fundamentalism," the view that it is a priori necessary that testimony provides some epistemic support, but perhaps not enough, absent defeat, for knowledge. In later work I abandon the view that the principle is a priori necessary, but I still maintain the distinction between Strong and Weak variants of the principle, and the replies to many of the objections to the principle.

Peter Graham has recently given a dilemma purportedly showing the compatibility of libertarianism about free will and the anti-skeptical epistemology of testimony. In the first part of this paper I criticize his dilemma: the first horn either involves a false premise or makes the dilemma invalid. The second horn relies without argument on an implausible assumption about testimonial knowledge, and even if granted, nothing on this horn shows libertarianism does not entail skepticism about testimonial justification. (...) I then argue for the incompatibility of (i) a view entailed by Open Theism, viz., that there are no true counterfactuals of freedom, (ii) a popular form of process reliabilism about justification and knowledge, and (iii) a weak anti-skepticism about testimonial justification and knowledge. I conclude that there is a costly tension between certain views about testimony and about free will. (shrink)

According to a standard interpretation of Aristotle, a material substance, like a dog, is a hylomorphic composite of matter and form, its “essential” parts. Is such a composite some thing in addition to its essential parts as united? The moderate reductionist says “no,” whereas the anti-reductionist says “yes.” In this paper, I will clarify and defend Durand of St.-Pourçain’s surprisingly influential version of moderate reductionism, according to which hylomorphic composites are nothing over and above their essential parts and (...) the union of those parts, where this union is explained by the presence of two modes: a mode of inherence on the side of form and a mode of substanding on the side of matter.

This paper identifies two distinct dimensions of what might be called testimonial strength: first, in the case of testimony from more than one speaker, testimony can be said to be stronger to the extent that a greater proportion of the speakers give identical testimony; second, in both single-speaker and multi-speaker testimony, testimony can be said to the stronger to the extent that each speaker expresses greater conviction in the relevant proposition. These two notions of testimonial (...) strength have received scant attention in the philosophical literature so far, presumably because it has been thought that whatever lessons we learn from thinking about testimony as a binary phenomenon will apply mutatis mutandis to varying strengths of testimony. This paper shows that this will not work for either of the two aforementioned dimensions of testimonial strength, roughly because less testimony can provide more justification in a way that can only be explained by appealing to the (non-binary) strength of the testimony itself. The paper also argues that this result undermines some influential versions of non-reductionism about testimonial justification. (shrink)

This article intends to show that the defense of “understanding” as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo (...) Mortimer, on the one hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students’ belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students.

I argue, first, that testimony is likely a natural kind (where natural kinds are accurately described by the homoeostatic property cluster theory) and that if it is indeed a natural kind, it is likely necessarily reliable. I argue, second, that the view of testimony as a natural kind and as necessarily reliable grounds a novel, naturalist global reductionism about testimonial justification and that this new reductionism is immune to a powerful objection to orthodox Humean global (...) reductionism, the objection from the too-narrow induction base.

The problem of explaining how we acquire knowledge via testimony gives rise to a dilemma, according to which any theory must make testimonial knowledge either too hard or too easy, and therefore no adequate account of testimonial knowledge is possible. In recent work, John Greco offers a solution to the dilemma on behalf of anti-reductionism that appeals to Edward Craig’s functionalist epistemology. It is argued that Greco’s solution is flawed, in that his functionalist account provides wrong verdicts (...) of ordinary cases of testimonial knowledge. In contrast, it is shown that both anti-reductionism and reductionism have the resources to solve the dilemma and provide the right verdicts in ordinary cases of testimonial knowledge without appealing to Greco’s functionalism.

There is an emerging skepticism about the existence of testimonial knowledge-how :387–404, 2010; Poston in Noûs 50:865–878, 2016; Carter and Pritchard in Philos Phenomenol Res 91:181–199, 2015a). This is unsurprising since a number of influential approaches to knowledge-how struggle to accommodate testimonial knowledge-how. Nonetheless, this scepticism is misguided. This paper establishes that there are cases of easy testimonial knowledge-how. It is structured as follows: first, a case is presented in which an agent acquires knowledge-how simply by accepting a speaker’s (...) testimony. Second, it is argued that this knowledge-how is genuinely testimonial. Next, Poston’s arguments against easy testimonial knowledge-how are considered and rejected. The implications of the argument differ for intellectualists and anti-intellectualists about knowledge-how. The intellectualist must reject widespread assumptions about the communicative preconditions for the acquisition of testimonial knowledge. The anti-intellectualist must find a way of accommodating the dependence of knowledge-how on speaker reliability. It is not clear how this can be done. (shrink)

A central theme in Wittgenstein’s post-Tractatus remarks on the limits of language is that we ‘cannot use language to get outside language’. One illustration of that idea is his comment that, once we have described the procedure of teaching and learning a rule, we have ‘said everything that can be said about acting correctly according to the rule’; ‘we can go no further’. That, it is argued, is an expression of anti-reductionism about meaning and rules. A (...) framework is presented for assessing the debate between reductionist and anti-reductionist readings of Wittgenstein’s views about meaning and use. It is argued that that debate cannot be settled merely by reference to Wittgenstein’s general opposition to reductionism. An important argument for anti-reductionism about rules and meaning, from Remarks on the Foundations of Mathematics, is discussed. Putative evidence of reductionism about meaning in the Brown Book is considered; an alternative reading is proposed. The nature of Wittgenstein’s anti-reductionism is examined. It is argued, first, that Wittgenstein accepts that semantic and normative facts supervene on non-semantic, non-normative facts and, second, that at many points his treatment of meaning and rules goes beyond the kind of pleonastic claim that is often taken to define non-reductionist, quietist, positions in philosophy.

In this paper, I spell out a new challenge for epistemic internalism that emerges out of the current debate on testimonial justification. Based on recent developments within this debate, one might argue as follows: Epistemic internalism can’t account for the justification of our testimony-based beliefs, because (1) we should conceive of testimonial justification along anti-reductionist lines and (2) anti-reductionism is incompatible with epistemic internalism. In response to this challenge, I show that, despite initial appearances, epistemic internalism (...) and anti-reductionism are compatible after all. Therefore, being an anti-reductionist with regard to testimonial justification doesn’t force one to reject epistemic internalism. In order to argue for this result, I will make use of resources provided by speech act theory. (shrink)

We’ll sketch the debate on testimony in social epistemology by reference to the contemporary debate on reductionism/anti-reductionism, communitarian epistemology and inferentialism. Testimony is a fundamental source of knowledge we share and it is worthy to be considered in the ambit of a dialogical perspective, which requires a description of a formal structure which entails deontic statuses and deontic attitudes. In particular, we’ll argue for a social reformulation of the “space of reasons”, which establishes a fruitful (...) relationship with the epistemological view of Wilfrid Sellars. (shrink)

Virtue signaling—using public moral discourse to enhance one’s moral reputation—is a familiar concept. But, what about profile pictures framed by “Vaccines work!”? Or memes posted to anti-vaccine groups echoing the group’s view that “Only sheep believe Big Pharma!”? These actions don’t express moral views—both claims are empirical (if imprecise). Nevertheless, they serve a similar purpose: to influence the judgments of their audience. But, where rainbow profiles guide their audience to view the agent as morally good, these acts guide (...) their audience to view the agent as epistemically good. They are instances of epistemic virtue signaling. The first goal of this paper is to offer an account of epistemic virtue signaling. I argue that epistemic virtue signaling occurs through both behavioral and propositional signals, and serves purposes similar to those of moral virtue signaling across a wide variety of discourses. The second is to show that there is much work for this concept to do. In particular, this concept illuminates a double bind faced by those who suffer from and seek to overcome testimonial injustice. I close by demonstrating how this double bind arises in the dissolution of medical autonomy, focusing on the care gap faced by pregnant women of color in the United States today, as compared with their white counterparts.

Kim’s causal exclusion argument purports to demonstrate that the non-reductive physicalist must treat mental properties (and macro-level properties in general) as causally inert. A number of authors have attempted to resist Kim’s conclusion by utilizing the conceptual resources of Woodward’s interventionist conception of causation. The viability of these responses has been challenged by Gebharter, who argues that the causal exclusion argument is vindicated by the theory of causal Bayesian networks (CBNs). Since the interventionist conception of causation relies crucially on CBNs (...) for its foundations, Gebharter’s argument appears to cast significant doubt on interventionism’s anti-reductionist credentials. In the present article, we both (1) demonstrate that Gebharter’s CBN-theoretic formulation of the exclusion argument relies on some unmotivated and philosophically significant assumptions (especially regarding the relationship between CBNs and the metaphysics of causal relevance), and (2) use Bayesian networks to develop a general theory of causal inference for multi-level systems that can serve as the foundation for an anti-reductionist interventionist account of causation.1.

According to anti-atomism, we represent color properties (e.g., red) in virtue of representing color relations (e.g., redder than). I motivate anti-atomism with a puzzle involving a series of pairwise indistinguishable chips. I then develop two versions of anti-atomism.

In the nineteenth century, the separation of naturalist or psychological accounts of validity from normative validity came into question. In his 1877 Logical Studies (Logische Studien), Friedrich Albert Lange argues that the basis for necessary inference is demonstration, which takes place by spatially delimiting the extension of concepts using imagined or physical diagrams. These diagrams are signs or indications of concepts' extension, but do not represent their content. Only the inference as a whole captures the objective content of the proof. (...) Thus, Lange argues, the necessity of an inference is independent of psychological accounts of how we grasp the content of a proposition. (shrink)

Anti-exceptionalism about logic is the doctrine that logic does not require its own epistemology, for its methods are continuous with those of science. Although most recently urged by Williamson, the idea goes back at least to Lakatos, who wanted to adapt Popper's falsicationism and extend it not only to mathematics but to logic as well. But one needs to be careful here to distinguish the empirical from the a posteriori. Lakatos coined the term 'quasi-empirical' `for the counterinstances to (...) putative mathematical and logical theses. Mathematics and logic may both be a posteriori, but it does not follow that they are empirical. Indeed, as Williamson has demonstrated, what counts as empirical knowledge, and the role of experience in acquiring knowledge, are both unclear. Moreover, knowledge, even of necessary truths, is fallible. Nonetheless, logical consequence holds in virtue of the meaning of the logical terms, just as consequence in general holds in virtue of the meanings of the concepts involved; and so logic is both analytic and necessary. In this respect, it is exceptional. But its methodologyand its epistemology are the same as those of mathematics and science in being fallibilist, and counterexamples to seemingly analytic truths are as likely as those in any scientic endeavour. What is needed is a new account of the evidential basis of knowledge, one which is, perhaps surprisingly, found in Aristotle. (shrink)

Reductionists about knowledge-wh hold that "s knows-wh" (e.g. "John knows who stole his car") is reducible to "there is a proposition p such that s knows that p, and p answers the indirect question of the wh-clause." Anti-reductionists hold that "s knows-wh" is reducible to "s knows that p, as the true answer to the indirect question of the wh-clause." I argue that both of these positions are defective. I then offer a new analysis of knowledge-wh as a (...) special kind of de re knowledge. (shrink)

I argue for the unexceptionality of evidence about what rationality requires. Specifically, I argue that, as for other topics, one’s total evidence can sometimes support false beliefs about this. Despite being prima facie innocuous, a number of philosophers have recently denied this. Some have argued that the facts about what rationality requires are highly dependent on the agent’s situation and change depending on what that situation is like. (Bradley 2019). Others have argued that a particular subset of (...) normative truths, those concerning what epistemic rationality requires, have the special property of being ‘fixed points’—it is impossible to have total evidence that supports false belief about them. (Smithies 2012; Titelbaum 2015). Each of these kinds of exceptionality permits a solution to downstream theoretical problems that arise from the possibility of evidence supporting false belief about requirements of rationality. However, as I argue here, they incur heavy explanatory burdens that we should avoid. (shrink)

This paper offers a critical assessment of the current state of the debate about the identity and individuality of material objects. Its main aim, in particular, is to show that, in a sense to be carefully specified, the opposition between the Leibnizian ‘reductionist’ tradition, based on discernibility, and the sort of ‘primitivism’ that denies that facts of identity and individuality must be analysable has become outdated. In particular, it is argued that—contrary to a widespread consensus—‘naturalised’ metaphysics supports both the (...) acceptability of non-qualitatively grounded (both ‘contextual’ and intrinsic) identity and a pluralistic approach to individuality and individuation. A case study is offered that focuses on non-relativistic quantum mechanics, in the context of which primitivism about identity and individuality, rather than being regarded as unscientific, is on the contrary suggested to be preferable to the complicated forms of reductionism that have recently been proposed. More generally, by assuming a plausible form of anti-reductionism about scientific theories and domains, it is claimed that science can be regarded as compatible with, or even as suggesting, the existence of a series of equally plausible grades of individuality. The kind of individuality that prevails in a certain context and at a given level can be ascertained only on the basis of the specific scientific theory at hand. (shrink)

Reductive accounts of the direction of time are often paired with Humean accounts of laws, while non-reductive accounts of time are often paired with anti-Humean accounts of laws. The traditional pairing of views has recently come under question. This paper aims to clarify what sorts of anti-Humean views motivate anti-reductionism about the direction of time. It is argued that those who think (i) that the laws are metaphysically fundamental, and (ii) that the laws contain time-asymmetric (...) contents, should treat the arrow of time as metaphysically fundamental.

Strawson (1994) and Peacocke (1992) introduced thought experiments that show that it seems intuitive that there is, in some way, an experiential character to mental events of understanding. Some (e.g., Siewert 1998, 2011; Pitt 2004) try to explain these intuitions by saying that just as we have, say, headache experiences and visual experiences of blueness, so too we have experiences of understanding. Others (e.g., Prinz 2006, 2011; Tye 1996) propose that these intuitions can be explained without positing experiences of understanding. (...) Call this the debate between Realism and Anti-Realism about experiences of understanding. This paper aims to advance that debate in two ways. In the first half, I develop more precise characterizations of what Realists and Anti-Realists propose. In the second half, I distinguish the four most plausible versions of Anti-Realism and argue that Realism better explains the target intuition than any of them does. (shrink)

One of the most important problems of twentieth century analytic philosophy concern the place of the mind – and in particular, of consciousness and intentionality – in a physical universe. Brian Loar’s essays in the philosophy of mind in this volume include his major contributions in this area. His central concern was how to understand consciousness and intentionality from the subjective perspective, and especially, how to understand subjectivity in a physical universe. He was committed to the reality and reliability of (...) the subjective perspective; and he found that subjective phenomena like intentionality and consciousness are, in a certain sense, ineliminable and irreducible to objective ones. At the same time he believed that intentionality and consciousness are grounded in the physical. One of his great contributions was showing how to reconcile these two positions by being a conceptual and explanatory anti-reductionist about both consciousness and intentionality but a metaphysical reductionist nonetheless. He had a deep commitment to both physicalism and to the reality and significance of the subjective point of view. (shrink)

Anti-exceptionalism about logic takes logic to be, as the name suggests, unexceptional. Rather, in naturalist fashion, the anti-exceptionalist takes logic to be continuous with science, and considers logical theories to be adoptable and revisable accordingly. On the other hand, the Adoption Problem aims to show that there is something special about logic that sets it apart from scientific theories, such that it cannot be adopted in the way the anti-exceptionalist proposes. In this paper I assess (...) the damage the Adoption Problem causes for anti-exceptionalism, and show that it is also problematic for exceptionalist positions too. My diagnosis of why the Adoption Problem affects both positions is that the self-governance of basic logical rules of inference prevents them from being adoptable, regardless of whether logic is exceptional or not.

According to epistemic reductionism about practical reasons, facts about practical reasons can be reduced to facts about evidence for ought-judgements. We argue that this view misconstrues practical conflicts. At least some conflicts between practical reasons put us in a position to know that an action ϕ is optional, i.e. that we neither ought to perform nor ought to refrain from performing the action. By understanding conflicts of practical reasons as conflicts of evidence about what one (...) ought to do, epistemic reductionism fails to account for this. In conflict cases in which ϕ-ing is optional, epistemic reductionism suggests that we have equally strong evidence for and against assuming that we ought to ϕ, and thus cannot be in a position to know that it is not the case that we ought to ϕ. This is a serious flaw. (shrink)

Social knowledge, for the most part, is knowledge through testimony. This essay is an overview of the epistemology of testimony. The essay separates knowledge from justification, characterizes testimony as a source of belief, explains why testimony is a source of knowledge, canvasses arguments for anti-reductionism and for reductionism in the reductionism vs. anti-reductionism debate, addresses counterexamples to knowledge transmission, defends a safe basis account of testimonial knowledge, and turns to social (...) norms as a partial explanation for the reliability of testimony.

Scientific anti-realists who appeal to the pessimistic induction (PI) claim that the theoretical terms of past scientific theories often fail to refer to anything. But on standard views in philosophy of language, such reference failures prima facie lead to certain sentences being neither true nor false. Thus, if these standard views are correct, then the conclusion of the PI should be that significant chunks of current theories are truth-valueless. But that is semantic anti-realism about scientific discourse—a position (...) most philosophers of science, anti-realists included, consider anathema today. Therefore, proponents of the PI confront a dilemma: either accept semantic anti-realism or reject common semantic views. I examine strategies (with particular emphasis on supervaluations) for the PI proponent to either lessen the sting of this argument, or learn to live with it. 1 Introduction2 Designation Failure 2.1 Designation failure leads to truth-valueless sentences2.1.1 Direct reference theory2.1.2 Fregeanism2.1.3 Accounts of reference-fixing: why ‘phlogiston’ fails to designate 2.2 Objection: sentences exhibiting designation failure are false not truth-valueless 2.3 Avoiding truth-valuelessness via controversial semantic positions3 What to do?

Almost everyone agrees that many testimonial beliefs constitute knowledge. According to non-reductionists, some testimonial beliefs possess positive epistemic status independent of that conferred by perception, memory, and induction. Recently, Jennifer Lackey has provided a counterexample to a popular version of this view. Here I argue that her counterexample fails.

Derek Parfit influentially defends reductionism about persons, the view that a person’s existence just consists in the existence of a brain and body and the occurrence of a series of physical and mental events. Yet some critics, particularly Mark Johnston, have raised powerful objections to Parfit’s reductionism. In this paper, I defend reductionism against Johnston. In particular, I defend a radical form of reductionism that Buddhist philosophers developed. Buddhist reductionism can justify key features of (...) Parfit’s position, such as the claims that personal identity is not what matters and can also be indeterminate. Furthermore, Buddhist reductionism can avoid Johnston’s objections to Parfit’s reductionism. I conclude that reductionists have good reasons to favor Buddhist reductionism over Parfit’s version.

Our aim in this paper is to defend the reductionist (or deflationist) view on group testimony from the attacks of divergence arguments. We will begin by presenting how divergence arguments can challenge the reductionist view. However, we will argue that these arguments are not decisive to rule out the reductionist view; for, these arguments have false premises, assuming dubious epistemic principles that testimony cannot generate knowledge and understanding. The final part of this paper will be devoted to presenting (...) the advantages of the reductionist approach to explaining the phenomenon of group testimony. (shrink)

This is an extended review of John Dupré's _Processes of Life_, a collection of essays. It clarifies Dupré's concepts of reductionism and anti-reductionism, and critically examines his associated discussions of downward causation, and both the context sensitivity and multiple realization of categories. It reviews his naturalistic monism, and critically distinguishes between his realism about categories and constructivism about classification. Challenges to his process ontology are presented, as are arguments for his pluralism about scientific categories. (...) None of his main conclusions are rejected; rather it is main arguments for them that are the focus. (shrink)

What is the relation between meaning and use? This chapter first defends a non-reductionist understanding of Wittgenstein’s suggestion that ‘the meaning of a word is its use in the language’; facts about meaning cannot be reduced to, or explained in terms of, facts about use, characterized non-semantically. Nonetheless, it is contended, facts about meaning do supervene on non-semantic facts about use. That supervenience thesis is suggested by comments of Wittgenstein’s and is consistent with his view of (...) meaning and rule-following. Semantic supervenience is then defended against two criticisms: first, John McDowell’s suggestion that the supervenience thesis falsifies the epistemology of meaning and fails to accommodate common-sense truths about meaning; second, a series of counter-examples proposed by Stephen Kearns and Ofra Magidor, who argue that worlds may differ semantically without differing non-semantically. It is argued that neither criticism is convincing: we should accept the thesis that semantic facts supervene on non-semantic facts. (shrink)

One of the defining features of the classical gene was its position. In molecular genetics, positions are defined instead as nucleotide numbers and there is no clear correspondence with its classical counterpart. However, the classical gene position did not simply disappear with the development of the molecular approach, but survived in the lab associated to different genetic practices. The survival of classical gene position would illustrate Waters’ view about the practical persistence of the genetic approach beyond reductionism and (...) anti-reductionist claims. We show instead that at the level of laboratory practices there are also reductive processes, operating through the rise and fall of different techniques. Molecular markers made the concept of classical gene position practically dispensable, leading us to rethink whether it had any causal role or was just a mere heuristic. (shrink)

While Kant was arguably as deeply engaged with the emerging special sciences of his time as he was with Newtonian physics, there is a deep tension in his treatment of these disciplines. On the one hand, Kant endorses a reductionist approach in natural science. On the other hand, Kant is committed to a variety of anti-reductionist positions in empirical psychology, chemistry, and the emerging biological sciences. This chapter examines the precise form that Kant’s anti-reductionism takes in each (...) of these domains and the corresponding set of questions about the extent to which each of these constitutes a genuine science for Kant.

It has become a common-place to read the ‘no-self’ theory of the Buddhist philosophers as a reductionist account of persons. In Reasons and Persons, Derek Parfit himself seemed to endorse the association, having learned of the Buddhist theory from his colleague at All Souls College, Bimal Krishna Matilal. The Buddha’s denial that there are real selves metaphysically distinct from continuous streams of psycho-physical constituents lends itself, to be sure, to a reductionist interpretation. I believe, nevertheless, that there are good grounds (...) for scepticism, and I think it is time for scholars of Buddhism to be more cautious about the identification than they have been up until now. Different Buddhist schools, not to mention different thinkers within particular schools, have given widely varying philosophical construals of the Buddha’s claim about ‘no-self’, and, while some thinkers and some schools might favor a reductionist reading of the claim, others, I would argue, do not. In this paper, I will examine the theory of persons of one such, the Mādhyamika Buddhist Candrakīrti. Candrakīrti’s interpretation of the “no self” slogan is, I believe, anti-reductionist but irrealist: persons are not reducible to psycho-physical streams, nor are they real existents distinct from the stream. How is it possible for him to say both these things? Let us see. (shrink)

​I evaluate a suggestion, floated by Kimberly Ferzan (this volume), that the twitter hashtag campaign #BelieveWomen is best accommodated by non-reductionist views of testimonial justification. I argue that the issue is ultimately one about the ethical obligation to trust women, rather than a question of what grounds testimonial justification. I also suggest that the hashtag campaign does not simply assert that ‘we should trust women’, but also militates against a pernicious striking-property generic (roughly: ‘women make false sexual assault accusations’), (...) that distorts our evaluation of women’s testimony concerning sexual assault. I conclude #BelieveWomen does not demand that we believe against the evidence, or uncritically, or be more trusting than we have evidential justification to be. Rather, it aims to bring our trust closer to what is merited by the base-rate of reliable testimony from women concerning sexual assault. (shrink)

My initial work, with collaborators Stephen Morris, Thomas Nadelhoffer, and Jason Turner (2005, 2006), on surveying folk intuitions about free will and moral responsibility was designed primarily to test a common claim in the philosophical debates: that ordinary people see an obvious conflict between determinism and both free will and moral responsibility, and hence, the burden is on compatibilists to motivate their theory in a way that explains away or overcomes this intuitive support for incompatibilism. The evidence, if any, (...) offered by philosophers to support the claim that incompatibilism is intuitive has consisted of reports of their own intuitions or informal polls of their students. We were skeptical about the reliability of such evidence, so we used the methodology--”now associated with the label 'experimental philosophy'--”of conducting formal surveys on non-philosophers. Our participants read a scenario that describes a deterministic universe and were then asked to judge whether agents in those scenarios act of their own free will and are morally responsible for their actions. Using three different scenarios with hundreds of participants, we consistently found that the majority (2/3 to 4/5) responded that agents in deterministic universes do act of their own free will and are morally responsible. That is, we found that most ordinary folk do not seem to find incompatibilism intuitive or obviously correct. Our results have been challenged in various ways, philosophical and methodological. For instance, Shaun Nichols (2004, this volume) and Nichols and Joshua Knobe (unpublished) offer some experimental evidence suggesting that, in certain conditions, most people express incompatibilist and libertarian intuitions. I will respond to this work in the following section. I agree that people express conflicting intuitions about free will (after all, we consistently found a minority of participants expressing incompatibilist. (shrink)

Laurence BonJour divides approaches to a priori justification into three kinds. Quine’s radical empiricism denies the existence of any special category of a priori justification; moderate empiricism attempts to explain a priori justification in terms of something like knowledge of meaning or grasp of concepts; and rationalism postulates an irreducible ‘rational insight’ into the nature of reality. The positions therefore form a familiar trio of eliminativism, reductionism and anti-reductionism concerning a priori justification. BonJour’s interesting and (in the (...) present philosophical climate) unusual project is to defend rationalism, the anti-reductionist position. Rationalism says that we have an ability to ‘directly or intuitively see or grasp or apprehend … a necessary fact about the nature or structure of reality’ (pp. 15-16). ‘An apparent rational insight,’ he says, ‘purports to be nothing less than a direct insight into the necessary character of reality’ (p. 107). Two clarifications will help to mark out the distinctive character of this view: first, that rational insight is fallible; and second, that although BonJour carefully distinguishes the concepts of necessity and apriority, he none the less claims that rational insight yields a priori knowledge of necessary truths only. On his view, the contingent a priori does not exist, although empirical necessities do... (shrink)

This paper analyses the anti-reductionist argument from renormalisation group explanations of universality, and shows how it can be rebutted if one assumes that the explanation in question is captured by the counterfactual dependence account of explanation.

A testimony is somebody else’s reported experience of what has happened. It is an indispensable source of knowledge. It only gives us historical cognition, however, which stands in a complex relation to rational or philosophical cognition: while the latter presupposes historical cognition as its matter, one needs the architectonic “eye of a philosopher” to select, interpret, and organize historical cognition. Kant develops this rationalist theory of testimony. He also practices it in his own work, especially while theorizing (...) class='Hi'>about race as a subject of natural philosophy. In three dedicated essays on this subject, he treats race from the standpoint of a philosophical investigator of nature (Naturforscher), who (as Kant puts it in the first Critique) learns from nature “like an appointed judge who compels witnesses to answer the questions he puts to them.” This view underwrites Kant’s use of travel reports (a type of testimony) in developing and defending his theory of race.

That testimony is one of the principle bases on which many people hold their religious beliefs is hard to dispute. Equally hard to dispute is that our world contains an array of mutually incompatible religious traditions each of which has been transmitted down the centuries chiefly by way of testimony. In light of this latter it is quite natural to think that there is something defective about holding religious beliefs primarily or solely on the basis of (...) class='Hi'>testimony from a particular tradition. The present chapter takes up the question of what that defect consists in. I first consider whether religious diversity entails that a religious believer’s testimony-based beliefs are not formed in a suitably epistemically reliable manner even conditional upon the truth of her religion. After casting doubt on this thought I turn to look at the idea that testimony-based beliefs are subject to defeaters in light of awareness of religious diversity, and I suggest that many such beliefs are not obviously so. According to my diagnosis the problem, rather, is that believers who base their religious beliefs just on testimony will be very unlikely to have reflective (that is, second-order) knowledge even if they possess first-order knowledge, and I explain why this is a notable shortcoming.

Anti-exceptionalism about logic is the thesis that logic is not special. In this paper, I consider, and reject, a challenge to this thesis. According to this challenge, there are basic logical principles, and part of what makes such principles basic is that they are epistemically exceptional. Thus, according to this challenge, the existence of basic logical principles provides reason to reject anti-exceptionalism about logic. I argue that this challenge fails, and that the exceptionalist positions motivated by (...) it are thus unfounded. I make this case by disambiguating two senses of ‘basic’ and showing that, once this disambiguation is taken into account, the best reason we have for thinking that there are basic principles actually implies that those principles do not require a special epistemology. Consequently, the existence of basic logical principles provides reason to accept, rather than reject, anti-exceptionalism concerning the epistemology of logic. I conclude by explaining how an abductivist, anti-exceptionalist approach to the epistemology of logic can accommodate the notion of basic logical principles. (shrink)
