Physicalism is the thesis that everything is physical, or as contemporary philosophers sometimes put it, that everything supervenes on, or is necessitated by, the physical. The thesis is usually intended as a metaphysical thesis, parallel to the thesis attributed to the ancient Greek philosopher Thales, that everything is water, or the idealism of the 18th Century philosopher Berkeley, that everything is mental. The general idea is that the nature of the actual world (i.e. the universe and everything in it) conforms (...) to a certain condition, the condition of being physical. Of course, physicalists don't deny that the world might contain many items that at first glance don't seem physical — items of a biological, or psychological, or moral, or social nature. But they insist nevertheless that at the end of the day such items are either physical or supervene on the physical. (shrink)

The identity theory of mind holds that states and processes of the mind are identical to states and processes of the brain. Strictly speaking, it need not hold that the mind is identical to the brain. Idiomatically we do use ‘She has a good mind’ and ‘She has a good brain’ interchangeably but we would hardly say ‘Her mind weighs fifty ounces’. Here I take identifying mind and brain as being a matter of identifying processes and perhaps states of the (...) mind and brain. Consider an experience of pain, or of seeing something, or of having a mental image. The identity theory of mind is to the effect that these experiences just are brain processes, not merely correlated with brain processes. (shrink)

1 Non-reductive physicalists deny that there is any explanation of mentality in purely physical terms, but do not deny that the mental is entirely determined by and constituted out of underlying physical structures. There are important issues about the stability of such a view which teeters on the edge of explanatory reductionism on the one side and dualism on the other (see Kim 1998). 2 Save perhaps for eliminative materialism (see Churchland 1981 for a classic exposition). In fact, however, while.

A comprehensive introduction to the Language of Though Hypothesis (LOTH) accessible to general audiences. LOTH is an empirical thesis about thought and thinking. For their explication, it postulates a physically realized system of representations that have a combinatorial syntax (and semantics) such that operations on representations are causally sensitive only to the syntactic properties of representations. According to LOTH, thought is, roughly, the tokening of a representation that has a syntactic (constituent) structure with an appropriate semantics. Thinking thus consists in (...) syntactic operations defined over representations. Most of the arguments for LOTH derive their strength from their ability to explain certain empirical phenomena like productivity, systematicity of thought and thinking. (shrink)

This article critically analyses the notion of intentionality from several philosophical cognitive points of view. The authors argue that the notion of mental representation in the wider sense and intentionality in the narrower sense remains elusive despite accommodated paradoxes, improved semantic precision and more sophisticated strategies in dealing with intentionality. We will argue that different approaches to intentionality appear to be coherent in their inferences. However, most of them become contradictory and mutually exclusive when juxtaposed and applied to borderline questions. (...) While the explanatory value of both philosophy of mind as well as cognitive psychology should not be underestimated, we must note that not even hard-core neuroscience has been able to pin point what is going on in our minds, let alone come up with a clear cut explanation how it works or a definition of what thought really is. To date, however, intentionality is the best of all explanatory models regarding mental representations. (shrink)

A preview of my book *Perception*. Discusses the relationship between perception and the physical world and the issue of whether reality is as it appears. Useful examples are included throughout the book to illustrate the puzzles of perception, including hallucinations, illusions, the laws of appearance, blindsight, and neuroscientific explanations of our experience of pain, smell and color. The book covers both traditional philosophical arguments and more recent empirical arguments deriving from research in psychophysics and neuroscience. The addition of chapter summaries, (...) suggestions for further reading and a glossary of terms make Perception essential reading for anyone studying the topic in detail, as well as for students of philosophy of mind, philosophy of psychology and metaphysics.

Among theory theorists, it is commonly thought that folk psychological theory is tacitly known. However, folk psychological knowledge has none of the central features of tacit knowledge. But if it is ordinary knowledge, why is it that we have difficulties expressing anything but a handful of folk psychological generalisations? The reason is that our knowledge is of theoretical models and hypotheses, not of universal generalisations. Adopting this alternative view of (scientific) theories, we come to see that, given time and reflection, (...) we can say what we know. (shrink)

1. Consider the basic outlines of the mind-body debate as it is found in contemporary Anglo-American analytic philosophy. The central question is “whether mental phenomena are physical phenomena, and if not, how they relate to physical phenomena.”1 Over the centuries, a wide range of possible solutions to this problem have emerged. These are the various “isms” familiar to any student of the debate: Cartesian dualism, idealism, epiphenomenalism, central state materialism, non- reductive physicalism, anomalous monism, and so forth. Each purports to (...) specify, among other things, the metaphysical relationship between the mental and the physical. They do so by specifying whether, or in what way, mental entities are identical to, reducible to, realized by, supervenient upon, or in causal interaction with physical entities. Thus, a convenient way to survey the range of positions is to enter them in a table. Rows correspond to the major kinds of metaphysical relation which might obtain between mental and physical entities. Each columns corresponds to one of the generic positions available in the debate. The particular theories defended by individual philosophers are usually just specific versions of generic positions. Thus Malebranche’s occasionalism is a version of causal dualism, distinguished by a peculiar account of the way in which causal interaction between mental and physical is actually effected. The central philosophical challenge is to determine which of these positions correctly describes the mental/physical relationship. Positions are evaluated for internal consistency, their fit with “intuitions,” their compatibility with scientific developments, and so forth. The mind-body debate, in this simple form, is set out in any number of. (shrink)

In his recent book, Jaegwon Kim argues thatpsychophysical supervenience withoutpsychophysical reduction renders mentalcausation `unintelligible'. He also claimsthat, contrary to popular opinion, his argumentagainst supervenient mental causation cannot begeneralized so as to threaten the causalefficacy of other `higher-level' properties:e.g., the properties of special sciences likebiology. In this paper, I argue that none ofthe considerations Kim advances are sufficientto keep the supervenience argument fromgeneralizing to all higher-level properties,and that Kim's position in fact entails thatonly the properties of fundamental physicalparticles are causally efficacious.

In this paper I highlight certain logical and metaphysical issues which arise in the characterisation of functionalism-in particular its ready coherence with a physicalist ontology, its structuralism and the impredicativity of functionalist specifications. I then utilise these points in an attempt to demonstrate fatal flaws in the functionalist programme. I argue that the brand of functionalism inspired by David Lewis fails to accommodate multiple realisability though such accommodation was vaunted as a key improvement over the identity theory. More standard accounts (...) of functionalism allow, by contrast, for far too much multiple realisability. Specifically, functionalist structures will be massively reduplicated in the human brain; so functionalism yields the absurd consequence that each human harbours large numbers of minds and exemplifies virtually all mental states. (shrink)

Many physicalists are vague about how defining‘physical property’fits in with characterizing physicalism. We determine the proper relation of these tasks. Employing panpsychism as a yardstick, we argue that defining‘physical property’and characterizing physicalism are subject to contradictory conditions of adequacy. We conclude that these tasks should be kept neatly apart. Exploiting this insight, we save physicalists from an apparently disastrous anti‐physicalist argument, we propose and defend a viable definition of‘physical property’, and we argue that the standard characterization of physicalism is flawed. (...) We propose an improved account. (shrink)

The phenomenal view of thought holds that thinking is an experience with phenomenal character that determines what the thought is about. This paper develops and responds to the objection that the phenomenal view is chauvinistic: it withholds thoughts from creatures that in fact have them. I develop four chauvinism objections to the phenomenal view—one from introspection, one from interpersonal differences, one from thought experiments, and one from the unconscious thought paradigm in psychology—and show that the phenomenal view can resist all (...) four.

Ramseyan humility is the thesis that we cannot know which properties realize the roles specified by the laws of completed physics. Lewis seems to offer a sceptical argument for this conclusion. Humean fundamental properties can be permuted as to their causal roles and distribution throughout spacetime, yielding alternative possible worlds with the same fundamental structure as actuality, but at which the totality of available evidence is the same. On the assumption that empirical knowledge requires evidence, we cannot know which of (...) these worlds is actual. However, Lewis also appeals to a range of familiar semantic principles when framing his argument, which leads some authors to suppose that he can also plausibly be interpreted as offering a purely semantic argument for humility in addition. In this paper I grant that these arguments are Lewisian, but argue that Lewis is also committed to a theory of mind that licenses a purely metaphysical argument for humility based on the idea that mental properties supervene on fundamental structure. Given that knowing which x is the F requires knowing that a is the F, the supposition that we could come to know which properties actually occupy the fundamental roles entails differences in mental properties between worlds with the same fundamental structure, violating supervenience. Humility follows right away, without any further epistemic or semantic principles. This argument is immune to almost every way of rebutting the sceptical and semantic arguments; conversely, almost every way of rebutting the metaphysical argument tells equally against the others.

I develop a conception of expressivism according to which it is chiefly a pragmatic thesis about some fragment of discourse, one imposing certain constraints on semantics. The first half of the paper uses credal expressivism about the language of probability as a stalking-horse for this purpose. The second half turns to the question of how one might frame an analogous form of expressivism about the language of deontic modality. Here I offer a preliminary comparison of two expressivist lines. The first, (...) expectation expressivism, looks again to Bayesian modelling for inspiration: it glosses deontically modal language as characteristically serving to express decision-theoretic expectation (expected utility). The second, plan expressivism, develops the idea (due to Gibbard 2003) that this language serves to express 'plan-laden' states of belief. In the process of comparing the views, I show how to incorporate Gibbard's modelling ideas into a compositional semantics for attitudes and modals, filling a lacuna in the account. I close with the question whether and how plan expressivism might be developed with expectation-like structure. (shrink)

It has recently been suggested that a distinctive metaphysical relation— ‘Grounding’—is ultimately at issue in contexts in which some goings-on are said to hold ‘in virtue of’’, be ‘metaphysically dependent on’, or be ‘nothing over and above’ some others. Grounding is supposed to do good work in illuminating metaphysical dependence. I argue that Grounding is also unsuited to do this work. To start, Grounding alone cannot do this work, for bare claims of Grounding leave open such basic questions as whether (...) Grounded goings-on exist, whether they are reducible to or rather distinct from Grounding goings-on, whether they are efficacious, and so on; but in the absence of answers to such basic questions, we are not in position to assess the associated claim or theses concerning metaphysical dependence. There is no avoiding appeal to the specific metaphysical relations typically at issue in investigations into dependence—for example, type or token identity, functional realization, classical mereological parthood, the set membership relation, the proper subset relation, the determinable/determinate relation, and so on—which are capable of answering these questions. But, I argue, once the specific relations are on the scene, there is no need for Grounding. (shrink)

This paper outlines a non-reductive counterfactual account of grounding along interventionist lines, and uses the account to argue that taking grounding seriously requires ascribing non-trivial truth-conditions to a range of counterpossible counterfactuals. This result allows for a diagnosis of a route to scepticism about grounding, as deriving at least in part from scepticism about non-trivial counterpossible truth and falsity.

Inscrutability arguments threaten to reduce interpretationist metasemantic theories to absurdity. Can we find some way to block the arguments? A highly influential proposal in this regard is David Lewis’ ‘ eligibility ’ response: some theories are better than others, not because they fit the data better, but because they are framed in terms of more natural properties. The purposes of this paper are to outline the nature of the eligibility proposal, making the case that it is not ad hoc, but (...) instead flows naturally from three independently motivated elements; and to show that severe limitations afflict the proposal. In conclusion, I pick out the element of the eligibility response that is responsible for the limitations: future work in this area should therefore concentrate on amending this aspect of the overall theory.

This paper discusses whether it can be known a priori that a particular term, such as water, is a natural kind term, and how this problem relates to Putnams claim that natural kind terms require an externalist semantics. Two conceptions of natural kind terms are contrasted: The first holds that whether water is a natural kind term depends on its a priori knowable semantic features. The second.

Externalism is widely endorsed within contemporary philosophy of mind and language. Despite this, it is far from clear how the externalist thesis should be construed and, indeed, why we should accept it. In this entry I distinguish and examine three central types of externalism: what I call foundational externalism, externalist semantics, and psychological externalism. I suggest that the most plausible version of externalism is not in fact a very radical thesis and does not have any terribly interesting implications for philosophy (...) of mind, whereas the more radical and interesting versions of externalism are quite difficult to support. (shrink)

Since Hilary Putnam and Saul Kripke's first attacks on traditional, descriptivist theories of natural kind terms, it has become customary to speak of the ‘Putnam-Kripke’ view of meaning and reference. This article argues that this is a mistake, and that Putnam's account of natural kind terms is importantly different from that of Kripke. In particular, Putnam has from the very start been sceptical of Kripke's modal claims, and in later papers he explicitly rejects the proposal that theoretical identity statements are (...) metaphysically necessary (if true). I suggest that this is wholly in line with Putnam's earlier, Quine-inspired writings on general terms, and his preoccupation with the philosophy of science. Moreover, I argue that the picture of general terms that emerges from Putnam's writings is more plausible than that suggested by Kripke. However, contrary to Putnam, I also suggest that Putnam's later views on natural kinds and natural kind terms do not support standard Twin Earth externalism. (shrink)

I consider a grand, yet neglected proposal put forward by Shoemaker—a functionalist theory of all properties. I argue that two possible ways of developing this proposal meet with substantial objections. However, if we are prepared to endorse an ontology of tropes, one of these functionalist analyses can be developed into an original and informative theory of properties.

According to an attractive account of belief, our beliefs have centered content. According to an attractive account of communication, we utter sentences to express our beliefs and share them with each other. However, the two accounts are in conflict. In this paper I explore the consequences of holding on to the claim that beliefs have centered content. If we do in fact express the centered content of our beliefs, the content of the belief the hearer acquires cannot in general be (...) identical to the content the speaker expresses. I sketch an alternative account of communication, the Recentering model, that accepts this consequence and explains how expressed and acquired content are related. (shrink)

I consider the problem of how to derive what an agent believes from their credence function and utility function. I argue the best solution of this problem is pragmatic, i.e. it is sensitive to the kinds of choices actually facing the agent. I further argue that this explains why our notion of justified belief appears to be pragmatic, as is argued e.g. by Fantl and McGrath. The notion of epistemic justification is not really a pragmatic notion, but it is being (...) applied to a pragmatically defined concept, i.e. belief. (shrink)

The main claim of this paper is that Andy Clark's most influential argument for ‘the extended mind thesis’ (EM henceforth) fails. Clark's argument for EM assumes that a certain form of common-sense functionalism is true. I argue, contra Clark, that the assumed brand of common-sense functionalism does not imply EM. Clark's argument also relies on an unspoken, undefended and optional assumption about the nature of mental kinds—an assumption denied by the very common-sense functionalists on whom Clark's argument draws. I also (...) critique Mark Sprevak's reductio of Clark's argument. Sprevak contends that Clark's argument does not merely entail EM; it entails an extended mind thesis so strong as to be absurd. He goes on to claim that Clark's argument should properly be viewed as a reductio of the very common-sense functionalism on which it depends. Sprevak's argument shares the flaw that afflicts Clark's argument, or so I claim. (shrink)

. Nonreductive physicalism, as opposed to reductionism, enjoys wide popularity by virtue of being regarded as comporting with the traditional image of human beings as free and ontologically unique without the difficulties of mind-body dualism. A consideration of reasons, both good and bad, for which reductionism is rejected suggests instead that the move to nonreductive physicalism does nothing to mitigate the implications of a physicalist account of human nature.

The Principal Principle (PP) says that, for any proposition A, given any admissible evidence and the proposition that the chance of A is x%, one's conditional credence in A should be x%. Humean Supervenience (HS) claims that, among possible worlds like ours, no two differ without differing in the spacetime-point-by-spacetime-point arrangement of local properties. David Lewis (1986b, 1994a) has argued that PP contradicts HS, and the validity of his argument has been endorsed by Bigelow et al. (1993), Thau (1994), Hall (...) (1994), Strevens (1995), Ismael (1996), Hoefer (1997), and Black (1998). Against this consensus, I argue that PP might not contradict HS: Lewis's argument is invalid, and every attempt – within a broad class of attempts – to amend the argument fails. (shrink)

Inspired both by our ordinary understanding of the world and by reflection on science, anti-Humeanism is a growing trend in metaphysics. Anti-Humeans reject the Lewisian doctrine of Humean supervenience that the world is “just one little thing and then another”, and argue instead that dispositions, powers, or capacities provide connection and activity in nature. But how exactly are we to understand the shared commitment of this anti-Humean movement? I argue that this kind of anti-Humeanism, at its most general level, is (...) to be understood neither as a view about ontology nor about fundamentality, but rather as a specific claim about what explains what.

In this paper, I discuss a view proposed by Carl Hempel in his paper Reduction: Ontological and Linguistic Facets, published in 1969. Here, Hempel suggested that questions regarding the identification of mental states with physiological states, the relation between sociological phenomena and individual behavioral states, and between biological and physicochemical states should be given what he calls a ‘linguistic’ interpretation. His main point is that whether or not an object is physical or biological depends on how it is, or can (...) be, described. In this paper, I wish to, firstly, explicate Hempel's suggestion, and, secondly, explore one argument in favor of Hempel's account. I will suggest that there is at least one use of the term ‘physical’ in philosophical discourse (and, for that matter, of related terms such as ‘biological’, ‘mental’, ‘natural’ etc.) that should be cashed out in linguistic or representational terms. (shrink)

What is it to know more? By what metric should the quantity of one's knowledge be measured? I start by examining and arguing against a very natural approach to the measure of knowledge, one on which how much is a matter of how many. I then turn to the quasi-spatial notion of counterfactual distance and show how a model that appeals to distance avoids the problems that plague appeals to cardinality. But such a model faces fatal problems of its own. (...) Reflection on what the distance model gets right and where it goes wrong motivates a third approach, which appeals not to cardinality, nor to counterfactual distance, but to similarity. I close the paper by advocating this model and briefly discussing some of its significance for epistemic normativity. In particular, I argue that the 'trivial truths' objection to the view that truth is the goal of inquiry rests on an unstated, but false, assumption about the measure of knowledge, and suggest that a similarity model preserves truth as the aim of belief in an intuitively satisfying way.

Is it true that all formative influence is unethical, and that we ought to avoid influencing children (and indeed anyone at all)? There are more or less defensible versions of this doctrine, and we shall follow some of the strands of argument that lead to this conclusion. It seems that in maintaining that all influence is immoral, one commits oneself to the idea that children have innate teleologies, that these may be frustrated, and that to frustrate a child’s innate teleology (...) would be to wrong them. First we consider a strong view of innate teleology exemplified in the writing of Plato. However, even those who favour such a view can approve of those formative influences which lead people to better realise their innate teleology. Next we consider a weaker version of the doctrine, one claiming that we ought to broaden the possibilities available to those that we influence, and never to narrow them. This seems too permissive a strategy, however. Finally Foss and Griffin’s worry about a desire for control and domination being embedded in persuasion is explored together with their proposed alternative strategy of ‘invitational rhetoric’. Ultimately, this paper argues that we often have good reason to encourage certain formative outcomes and discourage others. (shrink)

Functionalist theories have been proposed for just about everything: mental states, dispositions, moral properties, truth, causation, and much else. The time has come for a functionalist theory of nothing. Or, more accurately, a role functionalist theory of those absences that are causes and effects.

How should ‘the physical’ be defined for the purpose of formulating physicalism? In this paper I defend a version of the via negativa according to which a property is physical just in case it is neither fundamentally mental nor possibly realized by a fundamentally mental property. The guiding idea is that physicalism requires functionalism, and thus that being a type identity theorist requires being a realizer-functionalist. In §1 I motivate my approach partly by arguing against Jessica Wilson's no fundamental mentality (...) constraint. In §2 I set out my preferred definition of ‘the physical’ and make my case that physicalism requires functionalism. In §3 I defend my proposal by attacking the leading alternative account of ‘the physical,’ the theory-based conception. Finally, in §4 I draw on my definition, together with Jaegwon Kim's account of intertheoretic reduction, to defend the controversial view that physicalism requires a priori physicalism. (shrink)

I here defend microphysical manyism. According to microphysical manyism, each composite or higher-level object is a mere plurality of microphysical particles. After clarifying the commitments of the view, I offer two physicalist-friendly arguments in its favour. The first argument appeals to the Canberra Plan. Here I argue that microphysical particles acting in unison play the theoretical roles associated with composite objects - that they do everything that we think of composite objects as doing - and thus that composite objects are (...) to be identified with pluralities of microphysical particles. Along the way I rebut the objections that pluralities of particles don’t display the right emergent, ‘lingering’, or modal properties to be good candidates for identification with higher-level objects. In the second argument I claim that microphysical manyism is uniquely able to capture a compelling and widespread physicalist intuition concerning the intimate nature of the relationship between higher-level, composite objects and the microphysical world.

The practice of conceptual analysis has undergone a revival in recent years. Although the extent of its role in philosophy is controversial, many now accept that conceptual analysis has at least some role to play. Granting this, I consider the relevance of empirical investigation to conceptual analysis. I do so by contrasting an extreme position (anti-empirical conceptual analysis) with a more moderate position (non-empirical conceptual analysis). I argue that anti-empirical conceptual analysis is not a viable position because it has no (...) means for resolving conceptual disputes that arise between seemingly competent speakers of the language. This is illustrated by considering one such dispute that has been pressed by a prominent advocate of anti-empirical conceptual analysis: Bennett and Hacker ( 2003 ) assert that psychological predicates only logically apply to whole living animals, but many scientists and philosophers use the terms more broadly. I argue that to resolve such disputes we need to empirically investigate the common understanding of the terms at issue. I then show how this can be done by presenting the results of three studies concerning the application of “calculates” to computers. (shrink)

It's a common idea in philosophy that we possess a peculiar kind of "phenomenal concept" by which we can think about our conscious states in "inner" and "direct" ways, as for example, when I attend to the way a current pain feels and think about this feeling as such. Such phenomenal ways of thinking figure in a variety of theoretical contexts. The bulk of this article discusses their use in a certain strategy – the phenomenal concept strategy – for defending (...) the physicalist view that conscious states are reducible to brain states. It also considers, more briefly, how phenomenal concepts have been used to defend dualism about consciousness, and how they have been used to explain our special access to our consciousness. It concludes with a discussion about whether, and in what more precise sense of the term, we at all possess "phenomenal concepts" of our conscious states. (shrink)

Colours and consciousness both present us with metaphysical problems. But what exactly are the problems? According to standard accounts, they are roughly the following. On the one hand, we have reason to believe, about both colour and consciousness, that they are identical with some familiar natural phenomena. But on the other hand, it is hard to see how these identities could obtain. I argue that this is an adequate characterisation of our metaphysical problem of colour, but a mischaracterisation of the (...) problem of consciousness. It mischaracterises the problem by presenting consciousness as more 'colour-like' than we have reason to take it to be. The real problem of consciousness is, I suggest, that almost nothing theoretically useful is known about this phenomenon at present. I also explore some implications of this perspective on the problem of consciousness. Given the shape of the problem, I argue that we can't rule out all forms of eliminativism about consciousness. Nor can we rule out that future research will close the ' explanatory gap' that consciousness gives rise to. (shrink)

In this paper I argue that questions about the semantics of rigid designation are commonly and illicitly run together with distinct issues, such as questions about the metaphysics of essence and questions about the theoretical legitimacy of the possible-worlds framework. I discuss in depth two case studies of this phenomenon – the first concerns the relation between rigid designation and reference, the second concerns the application of the notion of rigidity to general terms. I end by drawing out some conclusions (...) about the relations between rigid designation, semantic frameworks, reference, and essence. (shrink)

David Lewis's approach to objective chance is doubly distinctive. On the one hand, Lewis uses an epistemic principle to disclose the nature of chance. One the other, Lewis conjoins realism about chance with a reductive Humean metaphysics. I aim to undermine both aspects of his view. Specifically, I argue that reductive Humeanism fails across the board, and I use my discussion of chance to explain why. I also argue Lewis's "best-systems" approach to chance fails his own criteria for a metaphysics (...) of chance. (edited). (shrink)

Many philosophers take mental causation to be required for free will. But it has also been argued that the most popular view of the nature of mental states, i.e. non-reductive physicalism, excludes the existence of mental causation, due to what is known as the ‘exclusion argument’. In this paper, I discuss the difference-making account of mental causation proposed by [List, C., and Menzies, P. 2017. “My Brain Made Me Do It: The Exclusion Argument Against Free Will, and What’s Wrong with (...) It.” In H. Beebee, C. Hitchcock, & H. Price (eds.), Making a Difference: Essays on the Philosophy of Causation. Oxford Scholarship Online: Oxford University Press], who argue that their account not only solves the problem of causal exclusion but also saves free will. More precisely, they argue that it rebuts what they call ‘the Neurosceptical Argument’, the argument that if actions are caused by neural states and processes unavailable to us, there is no free will. I argue that their argument fails for two independent reasons. The first reason is that they fail to show that difference-makers are independent causes. The second reason is that physical realizers of mental states can be individuated in a way that makes both mental states and their realizers difference-makers. (shrink)

What is the relation between entailment and reasons for belief? In this paper, I discuss several answers to this question, and I argue that these answers all face problems. I then propose the following answer: for all propositions p1,...,pn and q, if the conjunction of p1,..., and pn entails q, then there is a reason against a person's both believing that p1,..., and that pn and believing the negation of q. I argue that this answer avoids the problems that the (...) other answers to this question face, and that it does not face any other problems either. I end by showing what the relation between deductive logic, reasons for belief and reasoning is if this answer is correct. (shrink)
