This paper considers three package deals combining views in philosophy of mind, meta-philosophy, and experimental philosophy. The most familiar of these packages gives center-stage to pumping intuitions about fanciful cases, but that package involves problematic commitments both to a controversial descriptivist theory of reference and to intuitions that “negative” experimental philosophers have shown to be suspiciously variable and context-sensitive. In light of these difficulties, it would be good for future-minded experimental philosophers to align themselves with a different package deal. This (...) paper suggests two alternatives. Experimentalists might help fans of “naturalized” approaches discover what natural kinds have been playing an appropriate role in causing us to use concepts as we do. Or, better still, experimentalists might instead help pragmatists and teleo-semanticists discover how our concept usage regularly yields beneficial outcomes, so that we can then craft philosophical analyses that will..

A number of authors have suggested that a conditional analysis of dispositions must take roughly the following form: Thing X is disposed to produce response R to stimulus S just in case, if X were exposed to S and surrounding circumstances were auspicious, then X would produce R. The great challenge is cashing out the relevant notion of ‘auspicious circumstances’. I give a general argument which entails that all existing conditional analyses fail, and that there is no satisfactory way to (...) define ‘auspicious circumstances’ just in terms of S, R, and X. Instead, I argue that the auspicious circumstances C for the manifestation of a disposition constitute a third irreducible element of that disposition, and that to pick out (or to ‘individuate’) that disposition one must specify C along with S and R. This enables a new conditional analysis of dispositions that gives intuitively satisfying answers in cases that pose problems for other approaches. (shrink)

This paper contributes to an ongoing debate regarding the cognitive processes involved when one person predicts a target person's behavior and/or attributes a mental state to that target person. According to simulation theory, a person typically performs these tasks by employing some part of her brain as a simulation of what is going on in a corresponding part of the brain of the target person. I propose a general intuitive analysis of what 'simulation' means. Simulation is a particular way of (...) using one process to acquire knowledge about another process. What distinguishes simulation from other ways of acquiring knowledge is that simulation requires, for its non-accidental success, that the simulating process reflect significant aspects of the simulated process. This conceptual work is of independent philosophical interest, but it also enables me to argue for two conclusions that are of great significance to the debate about mental simulation theory. First, I argue that, in order to stake a non-trivial claim, simulation theory must hold that mental simulation involves what I call concretely similar processes. Second, I argue for the surprising conclusion that a significant class of cases that simulation theorists have claimed as intuitive cases of simulation do not actually involve simulation, after all. I close by sketching an alternative account that might handle these problematic cases. (shrink)

Mental internalists hold that an individuals mental features at a given time supervene upon what is in that individuals head at that time. While many people reject mental internalism about content and justification, mental internalism is commonly accepted regarding such other mental features as rationality, emotion-types, propositional-attitude-types, moral character, and phenomenology. I construct a counter-example to mental internalism regarding all these features. My counter-example involves two creatures: a human and an alien from Pulse World. These creatures environments, behavioral dispositions and (...) histories are such that it is intuitively clear that they are mentally quite different, even while they are, for a moment, exactly alike with respect to whats in their heads. I offer positive reasons for thinking that the case I describe is indeed possible. I then consider ways in which mental internalists might attempt to account for this case, but conclude that the only plausible option is to reject mental internalism and to adopt a particular externalist alternative a history-oriented version of teleo-functionalism.

considers what I call free-floating chances—objective chances that obtain at a given time despite the fact that their values are not determined by the laws of nature together with the full history of non-chancy facts up to that time. I offer an intuitive example of this phenomenon, and use it to argue that free-floating chances are indeed possible. Their possibility violates three quite widely held principles about chances: the lawful magnitude principle, the principle that chances evolve by conditionalization and a (...) version of David Lewis' principal principle. I argue that we should reject common formulations of each of these principles, though I offer revised understandings of each which retain much of the intuitive attractiveness of the originals and are consistent with the possibility of free-floating chances. I conclude by arguing that, while considerations of free-floating chances are important, they will not sustain the extravagant conclusions Lange attempts to draw from them.

This paper defends Pragmatic Conceptual Analysis , a proposed empirical methodology for explicating philosophical concepts. This methodology attributes to our shared concepts whatever application conditions they would need to have in order best to continue delivering benefits in the ways they have regularly delivered benefits in the past. In the first stage of my argument I argue that Pragmatic Conceptual Analysis has what I call normative authority : we have practical and epistemic reason to adopt the explications that it delivers (...) even if we think doing so requires stipulative revisions in the meanings of our concepts. I then use this normative authority to argue that Pragmatic Conceptual Analysis also has what I call descriptive authority : when we understand concept-meaning in the way we ought to understand it (in the way licensed by the normative authority of Pragmatic Conceptual Analysis) we see that, rather than being revisionary, Pragmatic Conceptual Analysis is a semantically conservative tool that uncovers (what we should think of as being) the meanings our concepts already have.

I develop and defend a version of what I call Disposition-Based Decision Theory (or DBDT). I point out important problems in David Gauthier’s (1985, 1986) formulation of DBDT, and carefully develop a more defensible formulation. I then compare my version of DBDT to the currently most widely accepted decision theory, Causal Decision Theory (CDT). Traditional intuition-based arguments fail to give us any strong reason to prefer either theory over the other, but I propose an alternative strategy for resolving this debate. (...) I argue that we should embrace DBDT because it does better than CDT at the work that we, as a matter of empirical fact, commonly call upon a notion of rationality to do. (shrink)

I consider the question of whether success-linked theories of content – theories like those of Ramsey (1927), Millikan (1984) and Blackburn (2005) which take there to be a definitional link between representational content and behavioral success – are consistent with the plausible claim that we can use content-attributions to explain behavioral success. Peter Godfrey-Smith (1996) argues that success-linked theories of content are too closely linked to success to be able to explain it. Against this, I present a plausible account of (...) how content-attributions make available good explanations of behavioral success, and argue that if we want our content-attributions to be able to do this explanatory work, then we actually need to embrace a success-linked theory of content.

The dissemination of models across disciplinary lines has become a phenomenon of interest to philosophers of science. To account for this phenomenon, philosophers have invented two units of analysis. The first identifies to the thing that transfers, model templates. The second identifies the thing to which transferable templates apply, landing zones. There exists a dynamic between the thing that is transferred and the thing to which transferrable templates apply. The use of a transferable template in a new domain requires reconception (...) of domain-specific phenomena. This paper examines two cases of model transfer, the use of the ideal gas law in biology by R.A. Fisher and the use of the virial theorem in chemistry by Richard Bader. These two stories of model transfer in biology and chemistry indicate a dimension to conceptual progress related to this dynamic. Using discourse on model transfer affords philosophers a novel approach for depicting the invention of, for instance, chemical concepts and resulting disputes. (shrink)

According to standard philosophical and clinical understandings, pain is an essentially mental phenomenon (typically, a kind of conscious experience). In a challenge to this standard conception, a recent burst of empirical work in experimental philosophy, such as that by Justin Sytsma and Kevin Reuter, purports to show that people ordinarily conceive of pain as an essentially bodily phenomenon—specifically, a quality of bodily disturbance. In response to this bodily view, other recent experimental studies have provided evidence that the ordinary (‘folk’) (...) concept of pain is more complex than previously assumed: rather than tracking only bodily or only mental aspects of pain, the ordinary concept of pain can actually track either of these aspects. The polyeidic (or ‘many ideas’) analysis of the folk concept of pain, as proposed by Emma Borg et al., captures this complexity. Whereas previous empirical support for the polyeidic view has focused on the context-sensitivity of the folk concept of pain, here we discuss individual differences in people’s ‘pain priors’—namely, their standing tendencies to think of pain in relatively mind-centric or body-centric ways. We describe a preliminary empirical study and present a small number of findings, which will be explored further in future work. The results we discuss are part of a larger programme of work which seeks to integrate philosophical pain research into clinical practice. For example, we hypothesise that variations in how patients with chronic pain are thinking about pain could help predict their responses to treatment. (shrink)

Justin makes a novel case, based on reflection on the “telos” of color vision, for a dispositional theory of colors. Justin’s case is highly suggestive, and comes tantalizingly close to resolving the debate in the metaphysics of color. But I have a few questions which I would like to see answered before I am converted.

Justin Fisher (2007) has presented a novel argument designed to prove that all forms of mental internalism are false. I aim to show that the argument fails with regard to internalism about phenomenal experiences. The argument tacitly assumes a certain view about the ontology of phenomenal experience, which (inspired by Alva Noe) I call the “snapshot conception of phenomenal experience.” After clarifying what the snapshot conception involves, I present Fisher with a dilemma. If he rejects the snapshot (...) conception, then his argument against phenomenal internalism collapses. But if he embraces the snapshot conception, then internalists may argue that in light of the snapshot conception, their view is not so implausible—and that if Fisher still disagrees, he owes us an argument that shows why phenomenal internalism is false even given the snapshot conception. I conclude the paper by showing that Fisher cannot escape my criticism by adjusting his argument so that it no longer depends on the snapshot conception. (shrink)

In his recent critical notice of The Bounds of Cognition in this journal, Justin Fisher advances a set of concerns that favor the hypothesis that, under certain circumstances, cognitive processes span the brain, body, and world. One is that it is too much to require that representations in cognitive process must have non-derived content. A second is that it is possible that extended objects bear non-derived content. A third is that extended cognition might advocate the extension of certain (...) general categories of cognition. A fourth is that Bounds misapplies Andy Clark and David Chalmers’ so-called “parity principle.” The purpose of this rejoinder is to show how Fisher’s concerns can be, or have already been, addressed.

I articulate the challenge disagreement poses for epistemic contextualism, and then discuss several possible replies on behalf of the contextualist.

As the premier early modern advocate of an Epicurean alternative to the prevailing neo-Scholastic framework of Aristotelianism, Pierre Gassendi promoted not only ancient but also innovative reasoning on behalf of atomism, probabilism, empiricism, psychological hedonism, social contractarianism, and a range of other stances associated with the philosophy of the Garden. Much commentary has focused on the extent to which Gassendi ‘baptizes’ Epicurean thought. Beyond this aspect of his Epicureanism are questions as to whether, and how, Gassendi is true to core (...) Epicurean thinking, and what he preserves and promotes as valuable to philosophical and natural investigations of his time. Indeed, much subsequent modern philosophy builds on or reacts to an Epicurean legacy bequeathed by Gassendi, comprising his adjustments to, constraints on, or corrections of, the canonical views. Yet, for all his amendments, he retains as a primary philosophical motivation the Epicurean goal of striving for ataraxia. In this, he signals his firm commitment to philosophy in the tradition of the canonical Epicurean views. And, as with Epicurus’ own notion, his account of the centrality of attaining tranquility directs us to a better understanding of our nature and that of the world around us; amenable, in Gassendi’s framework, to Christian thought and contemporary natural philosophical investigations.

This new and expanded edition of The Logic of Real Arguments explains a distinctive method for analysing and evaluating arguments. It discusses many examples, ranging from newspaper articles to extracts from classic texts, and from easy passages to much more difficult ones. It shows students how to use the question 'What argument or evidence would justify me in believing P?', and also how to deal with suppositional arguments beginning with the phrase 'Suppose that X were the case.' It aims to (...) help students to think critically about the kind of sustained, theoretical arguments which they commonly encounter in the course of their studies, including arguments about the natural world, about society, about policy, and about philosophy. It will be valuable for students and their teachers in a wide range of disciplines including philosophy, law and the social sciences. (shrink)

Can the Hippocratic and Judeo-Christian traditions be synthesized with contemporary thought about practical reason, virtue and community to provide real-life answers to the dilemmas of healthcare today? Bishop Anthony Fisher discusses conscience, relationships and law in relation to the modern-day controversies surrounding stem cell research, abortion, transplants, artificial feeding and euthanasia, using case studies to offer insight and illumination. What emerges is a reason-based bioethics for the twenty-first century; a bioethics that treats faith and reason with equal seriousness, that (...) shows the relevance of ancient wisdom to the complexities of modern healthcare scenarios and that offers new suggestions for social policy and regulation. Philosophical argument is complemented by Catholic theology and analysis of social and biomedical trends, to make this an auspicious example of a new generation of Catholic bioethical writing which has relevance for people of all faiths and none.

Epistemicists claim that vague predicates have precise but unknow- able cutoffs. I argue against against the standard, Williamsonian, answer, that appeals to metalinguistic safety: we can know that p even if our true belief that p is metalinguistically lucky. I then propose that epistemicists should be diagonalized epistemicists and show how this alternative formulation of the view avoids the chal- lenge. However, in an M. Night Shyamalan-style twist, I then argue we should not be diagonalized epistemicists either.

The overall moral status of an option—whether it is required, permissible, forbidden, or something we really should do—is explained by competition between the contributory reasons bearing on that option and the alternatives. A familiar challenge for accounts of this competition is to explain the existence of latitude: there are usually multiple permissible options, rather than a single required option. One strategy is to appeal to distinctions between reasons that compete in different ways. Philosophers have introduced various kinds of non-requiring reasons (...) that do not generate requirements, even if they win the competition. This paper rejects two familiar versions of this strategy, one appealing to merely justifying reasons and one appealing to merely commendatory reasons. It offers a new account of how reasons compete that instead appeals to a sharp distinction between the reasons against an option and the reasons for the alternatives to that option. (shrink)

Recent work in cognitive science of religion (CSR) is beginning to converge on a very interesting thesis—that, given the ordinary features of human minds operating in typical human environments, we are naturally disposed to believe in the existence of gods, among other religious ideas (e.g., seeAtran [2002], Barrett [2004; 2012], Bering [2011], Boyer [2001], Guthrie [1993], McCauley [2011], Pyysiäinen [2004; 2009]). In this paper, we explore whether such a discovery ultimately helps or hurts the atheist position—whether, for example, it lends (...) credence to atheism by explaining away religious belief or whether it actually strengthens some already powerful arguments against atheism in the relevant philosophical literature.We argue that the recent discoveries of CSR hurt, not help, the atheist position—that CSR, if anything, should not give atheists epistemic assurance.

Criticism plays an essential role in the growth of scientific knowledge. In some cases, however, criticism can have detrimental effects; for example, it can be used to ‘manufacture doubt’ for the purpose of impeding public policy making on issues such as tobacco consumption and greenhouse gas emissions (e.g., Oreskes & Conway 2010). In this paper, we build on previous work by Biddle and Leuschner (2015) who argue that criticism that meets certain conditions can be epistemically detrimental. We extend and refine (...) their account by arguing that such criticism can be epistemically corrupting—it can create social conditions that are conducive to the development of epistemic vice by agents operating within them.

In this paper, we review recent neuroimaging investigations of disorders of consciousness and different disciplines' understanding of consciousness itself. We consider potential tests of consciousness, their legal significance, and how they map onto broader themes in U.S. statutory law pertaining to advance directives and surrogate decision-making. In the process, we outline a taxonomy of themes to illustrate and clarify the variance in state-law definitions of consciousness. Finally, we discuss broader scientific, ethical, and legal issues associated with the advent of neuroimaging (...) for disorders of consciousness and conclude with policy recommendations that could help to mitigate confusion in this realm.

Reformed epistemology and cognitive science have remarkably converged on belief in God. Reformed epistemology holds that belief in God is basic—that is, belief in God is a natural, non-inferential belief that is immediately produced by a cognitive faculty. Cognitive science of religion also holds that belief in gods is (often) non-reflectively and instinctively produced—that is, non-inferentially and automatically produced by a cognitive faculty or system. But there are differences. In this paper, we will show some remarkable points of convergence, and (...) a few points of divergence, between Reformed epistemology and the cognitive science of religion. (shrink)

Experimental philosophy (or “x-phi”) is a way of doing philosophy. It is “traditional” philosophy, but with a little something extra: In addition to the expected philosophical arguments and engagement, x-phi involves the use of empirical methods to test the empirical claims that arise. This extra bit strikes some as a new, perhaps radical, addition to philosophical practice. We don’t think so. As this chapter will show, empirical claims have been common across the history of Western philosophy, as have appeals to (...) empirical observation in attempting to support or subvert these claims. While conceptions of philosophy have changed over time, across these changes we find philosophers employing empirical methods in pursuing their philosophical questions. Our primary aim in this chapter is to illustrate this fact. We begin by discussing the relevance of history to experimental philosophy (Section 2), then offer a necessarily condensed and highly selective history of empirical work in Western philosophy, ranging from the ancients (Section 3), to the early moderns (Section 4), to the late moderns (Section 5), and on to the present (Section 6).

Leading researchers in the philosophy of mind present and explore cutting edge research in the exciting new field of experimental philosophy.

Recent scholarship in philosophy of science and technology has shown that scientific and technological decision making are laden with values, including values of a social, political, and/or ethical character. This paper examines the role of value judgments in the design of machine-learning systems generally and in recidivism-prediction algorithms specifically. Drawing on work on inductive and epistemic risk, the paper argues that ML systems are value laden in ways similar to human decision making, because the development and design of ML systems (...) requires human decisions that involve tradeoffs that reflect values. In many cases, these decisions have significant—and, in some cases, disparate—downstream impacts on human lives. After examining an influential court decision regarding the use of proprietary recidivism-prediction algorithms in criminal sentencing, Wisconsin v. Loomis, the paper provides three recommendations for the use of ML in penal systems. (shrink)

Both advocates and critics of experimental philosophy often describe it in narrow terms as being the empirical study of people’s intuitions about philosophical cases. This conception corresponds with a narrow origin story for the field—it grew out of a dissatisfaction with the uncritical use of philosophers’ own intuitions as evidence for philosophical claims. In contrast, a growing number of experimental philosophers have explicitly embraced a broad conception of the sub-discipline, which treats it as simply the use of empirical methods to (...) inform philosophical problems. And this conception has a corresponding broad origin story—the field grew out of a recognition that philosophers often make empirical claims and that empirical claims call for empirical support. In this paper, I argue that the broad conception should be accepted, offering support for the broad origin story. (shrink)

In the first book of the Prior Analytics, Aristotle sets out, for the first time in Greek philosophy, a logical system. It consists of a deductive system (I.4-22), meta-logical results (I.23-26), and a method for finding and giving deductions (I.27-29) that can apply in “any art or science whatsoever” (I.30). After this, Aristotle compares this method with Plato’s method of division, a procedure designed to find essences of natural kinds through systematic classification. This critical comparison in APr I.31 raises an (...) interpretive puzzle: how can Aristotle reasonably juxtapose two methods that differ so much in their aims and approach? What can be gained by doing so? Previous interpreters have failed to show how this comparison is legitimate or what important point Aristotle is making. The goal of this paper is to resolve the puzzle. In resolving this puzzle we not only learn more about the relationship be- tween division and the syllogistic in Aristotle. We will also learn something about the motivation for the syllogistic itself, by seeing the role that it plays in his philosophy of science. (shrink)

I develop a reduction of grounding to essence. My approach is to think about the relation between grounding and essence on the model of a certain conceptof existential dependence.

I then use the account to resolve various (...) issues surrounding the concept of grounding and its connection with essence; apply the account to paradigm cases andto the impure logic of grounding; and respond to objections.

One problem for Molinism that critics of the view have pressed, and which Molinists have so far done little to address, is that even if there are true counterfactuals of freedom, it is puzzling how God could possibly know them. I defuse this worry by sketching a plausible model of the mechanics of middle knowledge which draws on William Alston’s direct acquaintance account of divine knowledge.

In this paper, I argue that absences pose a challenge to our understanding of physicalism that has not been properly appreciated. I do this by setting out a thought experiment involving a being in whom absence properties occupy the causal roles that functionalists take to define mental properties, in which case these absence properties realize the being’s mental properties. Such a being should be compatible with the truth of physicalism, I argue, even though its mental properties are neither themselves physical (...) properties nor are they realized/grounded in physical properties—instead, they are realized/grounded in (nonphysical) absence properties. I argue that the case serves as a counterexample to leading formulations of physicalism that appeal to realization or grounding, but not to standard supervenience-based formulations of physicalism, because the latter typically include negative truths in their supervenience base in addition to physical truths. I show how realization- and grounding-based formulations of physicalism might be revised to handle the problem, but also recommend that we rethink how we understand physicalism and the role that negative entities can play for physicalists.

This paper focuses on the concept of collective essence: that some truths are essential to many items taken together. For example, that it is essential to conjunction and negation that they are truth-functionally complete. The concept of collective essence is one of the main innovations of recent work on the theory of essence. In a sense, this innovation is natural, since we make all sorts of plural predications. It stands to reason that there should be a distinction between essential and (...) accidental plural predications if there is a distinction among singular predications. In this paper I defend the view that the concept of collective essence is governed by the principle of Monotonicity: that something is essential to some items only if it is essential to any items to which they belong.
