This chapter discusses the anti‐materialist arguments that purport to show that conscious phenomena are genuinely new, nonphysical features of reality. The anti‐materialist claims that zombies are indeed conceivable. To see why this might make trouble for the materialist, the chapter considers again what is supposed to distinguish materialism from property dualism. Given the characterization of the difference between the materialist and the property dualist, it becomes clear why the conceivability of a zombie counts against materialism. One of the most (...) influential anti‐materialist arguments is the one presented by Frank Jackson. Jackson starts by assuming that the thesis of physicalism entails that all information is physical information. The most straightforward physicalist theory is the Central State Identity Theory (CSIT). According to this view (Smart 1959) conscious mental states, such as pains or visual sensations, are identical to certain states of the central nervous system. The principal objection to this view is its inherent “chauvinism”. (shrink)

This paper provides a reinterpretation of some of the most influential skeptical arguments, Agrippa’s trilemma, meta-regress arguments, and Cartesian external world skepticism. These skeptical arguments are reasonably regarded as unsound arguments about the extent of our knowledge. However, reinterpretations of these arguments tell us something significant about the preconditions and limits of persuasive argumentation. These results contribute to the ongoing debates about the nature and resolvability of deep disagreement. The variety of skeptical arguments (...) shows that we must distinguish different types of deep disagreement. Moreover, the reinterpretation of skeptical arguments elucidates that deep disagreement cannot be resolved via argumentation. (shrink)

The knowledge norm of assertion is mainly in competition with a high probability or rational credibility norm. The argument for the knowledge norm that I offer turns on cases in which a hearer responds to a speaker's assertion by asserting another sentence that would lower the probability of the speaker's assertion, were its probability less than one. In cases like this, though with qualifications, is the hearer's contribution a challenge to the speaker's assertion or complementary to it? My answer is (...) the latter, and that only the knowledge norm yields that answer.The cases that I rely on follow from an elementary probability relation, though one that is inconsistent with the still influential relevance criterion for confirmation and evidence . Assume, for illustrative purposes, that p is in your belief corpus, as a consequence of your believing ∨ ∨ . 1 You learn that ∼ & ∼ , which would lessen the probability of p, were its probability less than one, 2 since it eliminates two rows of the truth-table in which p holds. What conclusion do you reach about p?Rather than withdrawing p, you acquire the belief that p & ∼ s & ∼ r, even though Formula where pr would be the subjective or epistemic probability of p on a probabilistic view of the knowledge norm before learning ∼ & ∼ . Instead of withdrawal …. (shrink)

According to the Bayesian paradigm in the psychology of reasoning, the norms by which everyday human cognition is best evaluated are probabilistic rather than logical in character. Recently, the Bayesian paradigm has been applied to the domain of argumentation, where the fundamental norms are traditionally assumed to be logical. Here, we present a major generalisation of extant Bayesian approaches to argumentation that utilizes a new class of Bayesian learning methods that are better suited to modelling dynamic and conditional inferences than (...) standard Bayesian conditionalization, is able to characterise the special value of logically valid argument schemes in uncertain reasoning contexts, greatly extends the range of inferences and argumentative phenomena that can be adequately described in a Bayesian framework, and undermines some influential theoretical motivations for dual function models of human cognition. We conclude that the probabilistic norms given by the Bayesian approach to rationality are not necessarily at odds with the norms given by classical logic. Rather, the Bayesian theory of argumentation can be seen as justifying and enriching the argumentative norms of classical logic. (shrink)

Cartesian skepticism about epistemic justification (‘skepticism’) is the view that many of our beliefs about the external world – e.g., my current belief that I have hands – aren’t justified. I examine the two most influential arguments for skepticism – the Closure Argument and the Underdetermination Argument – from an evidentialist perspective. For both arguments it is clear which premise the anti-skeptic must deny. The Closure Argument, I argue, is the better argument in that its key premise (...) is weaker than the Underdetermination Argument’s key premise. However, it’s also likely that the motivation for accepting both key premises is exactly the same. So there may be a sense in which both arguments provide exactly the same motivation for skepticism. Then I argue that if I I’m right about what the motivation for accepting the arguments’ key premises is, then neither argument succeeds in providing a good reason to accept skepticism. I conclude by explaining why I think epistemologists are right to expend a lot of time and effort on refuting these arguments, even if neither argument provides any motivation for skepticism.

Virtue theories have become influential in ethics and epistemology. This paper argues for a similar approach to argumentation. Several potential obstacles to virtue theories in general, and to this new application in particular, are considered and rejected. A first attempt is made at a survey of argumentational virtues, and finally it is argued that the dialectical nature of argumentation makes it particularly suited for virtue theoretic analysis.

The consequence argument is among the most influential arguments for the conclusion that free will and determinism are incompatible. Recently, however, it has become increasingly clear that the argument fails to establish that particular incompatibilist conclusion. Even so, a version of the argument can be formulated that supports a different incompatibilist conclusion, according to which free will is incompatible with our behavior being predetermined by factors beyond our control. This conclusion, though not equivalent to the traditional incompatibilist thesis (...) that determinism strictly precludes free will, is something many incompatibilists have had in mind all along and, indeed, is arguably the more central incompatibilist position. The consequence argument thus remains philosophically important, even if, as several of its critics have argued, it can't be used to establish the strict incompatibility of free will and determinism.

The practice of justifying scientific explanations generates argumentative patterns in which several types of arguments may play a role. This paper is aimed at identifying these patterns on the basis of an exploration of the institutional conventions regarding the nature, the shape and the quality of scientific explanations as reflected in the writings of influential philosophers of science. First, a basic pattern for justifying scientific explanations is described. Then, two types of extensions of this pattern are presented. These (...) extensions are derived from philosophical accounts of requirements for the quality of explanations and the choice of the best explanation from a number of candidate explanations respectively. The description of the second extension will make clear how pragmatic argumentation plays a role in argumentative patterns within the scientific domain. (shrink)

Some influential arguments in the metaphysics of consciousness, in particular Chalmers’ Zombie Argument, suppose that all the physical properties of composed physical systems are metaphysically necessitated by their fundamental constituents. In this paper I argue against this thesis in order to debate Chalmers’ argument. By discussing, in non-technical terms, an EPR system I try to show that there are good reasons to hold that some composed physical systems have properties which are nomologically necessitated by their fundamental constituents, i.e., (...) which emerge in the sense of the so-called ‘nomological supervenience’ views.

Karl Marx and Sigmund Freud provided powerful accounts of systematic interested ignorance. Fifty years ago, Anglo-American philosophies of science stigmatized Marx's and Freud's analyses as models of irrationality. They remain disvalued today, at a time when virtually all other humanities and social science disciplines have returned to extract valuable insights from them. Here the argument is that there are reasons distinctive to philosophy why such theories were especially disvalued then and why they remain so today. However, there are even better (...) reasons today for philosophy to break from this history and find more fruitful ways to engage with systematic interested ignorance. (shrink)

The anti-realist argument from underconsideration focuses on the fact that, when scientists evaluate theories, they only ever consider a subset of the theories that can account for the available data. As a result, when scientists judge one theory to be superior to competitor theories, they are not warranted in drawing the conclusion that the superior theory is likely true with respect to what it says about unobservable entities and processes. I defend the argument from underconsideration from the objections of Peter (...) Lipton. I argue that the inconsistency that Lipton claims to find in the argument vanishes once we understand what the anti-realist means when she claims that scientists are reliable. I also argue that collapsing the distinction between relative and absolute evaluations, as Lipton recommends, has its costs. Finally, I briefly examine Richard Boyd's influential defence of realism.

Perspectivists hold that what you ought to do is determined by your perspective, that is, your epistemic position. Objectivists hold that what you ought to do is determined by the facts irrespective of your perspective. This paper explores an influential argument for perspectivism which appeals to the thought that the normative is action guiding. The crucial premise of the argument is that you ought to φ only if you are able to φ for the reasons which determine that you (...) ought to φ. We show that this premise can be understood in different ways. On one reading, it provides no support for perspectivism. On another reading, the premise lacks support. So, the argument fails. An important upshot of the paper is that the objectivist can embrace the thought about guidance. (shrink)

When it comes to evaluating reductive hypotheses in metaphysics, supervenience arguments are the tools of the trade. Jaegwon Kim and Frank Jackson have argued, respectively, that strong and global supervenience are sufficient for reduction, and others have argued that supervenience theses stand in need of the kind of explanation that reductive hypotheses are particularly suited to provide. Simon Blackburn's arguments about what he claims are the specifically problematic features of the supervenience of the moral on the natural have (...) also been influential. But most discussions of these arguments have proceeded under the strong and restrictive assumptions of the S5 modal logic. In this paper we aim to remedy that defect, by illustrating in an accessible way what happens to these arguments under relaxed assumptions and why. The occasion is recent work by Ralph Wedgwood, who seeks to defend non-reductive accounts of moral and mental properties together with strong supervenience, but to evade both the arguments of Kim and Jackson and the explanatory challenge by accepting only the weaker, B, modal logic. In addition to drawing general lessons about what happens to supervenience arguments under relaxed assumptions, our goal is therefore to shed some light on both the virtues and costs of Wedgwood's proposal.

Words, languages, symphonies, fictional characters, games, and recipes are plausibly abstract artifacts— entities that have no spatial location and that are deliberately brought into existence as a result of creative acts. Many accept that composition is unrestricted: for every plurality of material objects, there is a material object that is the sum of those objects. These two views may seem entirely unrelated. I will argue that the most influential argument against restricted composition—the vagueness argument—doubles as an argument that there (...) can be no abstract artifacts. There is no way to resist the vagueness argument against abstract artifacts that does not also undermine the vagueness argument against restricted composition. (shrink)

Recent progress in artificial intelligence (AI) has drawn attention to the technology’s transformative potential, including what some see as its prospects for causing large-scale harm. We review two influential arguments purporting to show how AI could pose catastrophic risks. The first argument — the Problem of Power-Seeking — claims that, under certain assumptions, advanced AI systems are likely to engage in dangerous power-seeking behavior in pursuit of their goals. We review reasons for thinking that AI systems might seek (...) power, that they might obtain it, that this could lead to catastrophe, and that we might build and deploy such systems anyway. The second argument claims that the development of human-level AI will unlock rapid further progress, culminating in AI systems far more capable than any human — this is the Singularity Hypothesis. Power-seeking behavior on the part of such systems might be particularly dangerous. We discuss a variety of objections to both arguments and conclude by assessing the state of the debate. (shrink)

Many philosophers believe that our ordinary English words man and woman are “gender terms,” and gender is distinct from biological sex. That is, they believe womanhood and manhood are not defined even partly by biological sex. This sex/gender distinction is one of the most influential ideas of the twentieth century on the broader culture, both popular and academic. Less well known are the reasons to think it’s true. My interest in this paper is to show that, upon investigation, the (...) arguments for the sex/gender distinction have feet of clay. In fact, they all fail. We will survey the literature and tour arguments in favor of the sex/gender distinction, and then we’ll critically evaluate those arguments. We’ll consider the argument from resisting biological determinism, the argument from biologically intersex people and vagueness, the argument from the normativity of gender, and some arguments from thought experiments. We’ll see that these arguments are not up to the task of supporting the sex/gender distinction; they simply don’t work. So, philosophers should either develop stronger arguments for the sex/gender distinction, or cultivate a variety of feminism that’s consistent with the traditional, biologically-based definitions of woman and man.

Toulmin’s scheme for the layout of arguments (1958, The Uses of Argument, Cambridge University Press, Cambridge) represents an influential tool for the analysis of arguments. The scheme enriches the traditional premises-conclusion model of arguments by distinguishing additional elements, like warrant, backing and rebuttal. The present paper contains a formal elaboration of Toulmin’s scheme, and extends it with a treatment of the formal evaluation of Toulmin-style arguments, which Toulmin did not discuss at all. Arguments are (...) evaluated in terms of a so-called dialectical interpretation of their assumptions. In such an interpretation, an argument’s assumptions can be evaluated as defeated, e.g., when there is a defeating reason against the assumption. The present work builds on recent research on defeasible argumentation (cf. e.g. the work of Pollock, Reiter, Loui, Vreeswijk, Prakken, Hage and Dung). More specifically, the author’s work on the dialectical logic DEFLOG and the argumentation tool ARGUMED serve as starting points. (shrink)

Two chapters -- "Common Arguments about Abortion" and "Better (Philosophical) Arguments About Abortion" -- in one file, from the open access textbook "Introduction to Ethics: An Open Educational Resource" edited by Noah Levin. -/- Adults, children and babies are arguably wrong to kill, fundamentally, because we are conscious, aware and have feelings. Since early fetuses entirely lack these characteristics, we argue that they are not inherently wrong to kill and so most abortions are not morally wrong, since most (...) abortions are done early in pregnancy before consciousness and feeling develop in the fetus. Furthermore, since the right to life is not the right to someone else’s body, fetuses might not have the right to the pregnant woman’s body, and so she has the right to not allow the fetus use of her body; this further justifies abortion, at least, until technology allows for the removal of fetuses to other wombs. Since morally permissible actions should be legal, abortions should be legal. -/- In the course of arguing for these claims, we: -/- discuss how to best define abortion; dismiss many common “question-begging” arguments that merely assume their conclusion, instead of giving genuine reasons for them; refute some often-heard “everyday arguments” about abortion; explain why some influential philosophical arguments against abortion are unsuccessful; provide some positive arguments that at least early abortions are not wrong; briefly discuss the ethics and legality of later abortions, and more. -/- Little of this discussion should be taken as absolute “proof” of anything, as this is merely a reasoned introduction to the issues: much more needs to be discussed, always.

In this paper, I critically discuss one of the more influential arguments for mereological universalism, what I will call ‘the Vagueness Argument’. I argue that a premise of the Vagueness Argument is not well supported and that there are at least two good reasons for thinking that the premise in question is false.

Social advertising often employs persuasive imagery in support of a morally laden cause. These visual arguments can take the form of veridical representations of the given situation or the form of purposeful visual blends. Both visual routes to persuasion have serious ethical issues to confront. In what concerns the purportedly veridical images, controversies about picture retouching and framing have cast many doubts on their success in offering unmediated access to a given reality. Editorial interests have proven far too (...) class='Hi'>influential on the destiny of what and how is presented to the audience from the amount of visual material available on a topic. Even when the audience is certain that photos are not doctored, the use of veridical images may be seen as unethical. Their disproportionate affective impact may lead the audience to hold biased opinions, since other concerns may be impossible to capture in a vivid picture. Visual blends may be the answer to this problem, employing the fictional or the figurative to help the viewer grasp the moral anatomy of a given situation. Their generous use of figurative meaning may be seen as their strength and their weakness at the same time. It makes them less likely to face accusations of distorting reality, because they do not claim to be windows on reality per se. At the same time, it makes them vulnerable to interpretations that miss their true point – one might appreciate the artistry of a visual metaphor or a visual pun and fail to consider the statement it makes about a given situation. Contemporary philosophical approaches to the place of visuals in moral persuasion inform my analysis of the use of visual arguments in charity-oriented advertising. (shrink)

One of the most influential arguments for realism about mathematical objects is the indispensability argument. Simply put, this is the argument that insofar as we are committed to the existence of the physical objects existentially quantified over in our best scientific theories, we are also committed to the mathematical objects existentially quantified over in these theories. Following the Quine–Putnam formulation of the indispensability argument, some proponents of the indispensability argument have made the mistake of taking confirmational holism to (...) be an essential premise of the argument. In this paper, I consider the reasons philosophers have taken confirmational holism to be essential to the argument and argue that, contrary to the traditional view, confirmational holism is dispensable.

The paper is a sustained analysis of some recent work on transcendental arguments with a view to assessing both its relevance to Kant's philosophy and its historical accuracy. Robert Stem's reading of Kant's philosophical aims is examined and criticized narrowly, and Barry Stroud's influential objection to transcendental arguments as a class is shown to be harmless. Kant is presented as a friend rather than a foe of scepticism, and his 'proto-verificationist' criterion of meaning is shown to underpin, (...) rather than undermine, the sceptical position.

Inferences from scientific success to the approximate truth of successful theories remain central to the most influential arguments for scientific realism. Challenges to such inferences, however, based on radical discontinuities within the history of science, have motivated a distinctive style of revision to the original argument. Conceding the historical claim, selective realists argue that accompanying even the most revolutionary change is the retention of significant parts of replaced theories, and that a realist attitude towards the systematically retained constituents (...) of our scientific theories can still be defended. Selective realists thereby hope to secure the argument from success against apparent historical counterexamples. Independently of that objective, historical considerations have inspired a further argument for selective realism, where evidence for the retention of parts of theories is itself offered as justification for adopting a realist attitude towards them. Given the nature of these arguments from success and from retention, a reasonable expectation is that they would complement and reinforce one another, but although several theses purport to provide such a synthesis the results are often unconvincing. In this paper I reconsider the realist’s favoured type of scientific success, novel success, offer a revised interpretation of the concept, and argue that a significant consequence of reconfiguring the realist’s argument from success accordingly is a greater potential for its unification with the argument from retention.Keywords: Scientific realism; Pessimistic meta-induction; Success; Progress; Aether; Novelty.

In a series of influential articles Jaegwon Kim has developed strong arguments against nonreductive physicalism as a possible solution to the problem of mental causation. One of them is the Supervenience Argument which states that assuming the mental/physical supervenience thesis, the causal closure principle, the exclusion principle with the no-overdetermination requirement and property dualism we obtain the conclusion that mental causation is unintelligible. On the other hand Collin McGinn has argued that a solution to the mind-body problem is (...) forever beyond our reach: we can never understand how the brain produces consciousness and therefore the relation between them must remain mysterious. The main aim of the paper is to demonstrate that Kim's Supervenience Argument corroborates McGinn's pessimistic conclusion (of course, if we do not assume any form of reductive physicalism or epiphenomenalism). Thereby it tries to show that the Supervenience Argument could be treated as a justification of non-constructive naturalism (aka new misterianism): we do not understand mental causation, because we cannot understand how the brain generates consciousness. It also suggest considering possibility that the thesis of causal closure of the physical domain might entail the cognitive closure thesis (the claim that those properties of the brain which are responsible for conscious processes are in principle cognitively closed to us).

One of the most influential arguments against compatibilism is Derk Pereboom’s four-case manipulation argument. Professor Plum, the main character of the thought experiment, is manipulated into doing what he does; he therefore supposedly lacks moral responsibility for his action. Since he is arguably analogous to an ordinary agent under determinism, Pereboom concludes that ordinary determined agents lack moral responsibility as well. I offer a hard-line reply to this argument, that is, a reply which denies that this kind of (...) manipulation is responsibility undermining. I point out that fully fleshed-out manipulated characters in fiction can seem morally responsible for what they do. This is plausibly because we identify with such characters, and therefore focus on their options and the reasons for which they act rather than the manipulation. I further argue that we ought to focus this way when interacting with other agents. We have no reason to trust the incompatibilist intuitions that arise when we regard manipulated agents from a much more detached perspective. (shrink)

Independence is the condition that, if X is preferred to Y, then a lottery between X and Z is preferred to a lottery between Y and Z given the same probability of Z. Is it rationally required that one’s preferences conform to Independence? The main objection to this requirement is that it would rule out the alleged rationality of Allais and Ellsberg Preferences. In this paper, I put forward a sequential dominance argument with fairly weak assumptions for a variant of (...) Independence (called Independence for Constant Prospects), which shows that Allais and Ellsberg Preferences are irrational. Hence this influential objection (that is, the alleged rationality of Allais and Ellsberg Preferences) can be rebutted. I also put forward a number of sequential dominance arguments that various versions of Independence are requirements of rationality. One of these arguments is based on very minimal assumptions, but the arguments for the versions of Independence which are strong enough to serve in the standard axiomatization of Expected Utility Theory need notably stronger assumptions.

This paper consists of two parts. The first concerns the logic of vagueness. The second concerns a prominent debate in metaphysics. One of the most widely accepted principles governing the ‘definitely’ operator is the principle of Distribution: if ‘p’ and ‘if p then q’ are both definite, then so is ‘q’. I argue however, that epistemicists about vagueness should reject this principle. The discussion also helps to shed light on the elusive question of what, on this framework, it takes for (...) a sentence to be borderline or definite. In the second part of the paper, I apply this result to a prominent debate in metaphysics. One of the most influential arguments in favour of Universalism about composition is the Lewis-Sider argument from vagueness. An interesting question, however, is whether epistemicists have any particular reasons to resist the argument. I show that there is no obvious reason why epistemicists should resist the argument but there is a non-obvious one: the rejection of Distribution argued for in the first part of the paper provides epistemicists with a unique way of resisting the argument from vagueness.

According to the conceivability argument, physicalism is false since it is conceivable and hence possible that the physical truth do not entail the phenomenal truth. The influential way of responding to the conceivability argument is to claim that our conceivability intuitions can be accounted for in purely psychological terms, by appealing to some cognitive and functional differences between phenomenal and physical concepts, and that therefore what is conceivable does not entail what is possible. On this account, the entailment from (...) the physical to the phenomenal that physicalism is committed to can be necessary and a posteriori. I argue that this way of responding to the conceivability argument cannot work. The conceivability argument depends on an assumption which implies that the psychophysical entailment cannot be necessary and a posteriori and appealing to the differences between phenomenal and physical concepts has no force against that assumption.

Whereas a number of recent articles have focussed upon whether the thesis of content externalism is compatible with a certain sort of knowledge that is gained via first-person authority,1 far less attention has been given to the relationship that this thesis bears to the possession of knowledge in general and, in particular, its relation to internalist and externalist epistemologies. Nevertheless, although very few actual arguments have been presented to this end, there does seem to be a shared suspicion that (...) content externalism must be incompatible with epistemic internalism. In a recent and influential paper, however, James Chase has challenged this conventional wisdom by offering a subtle defence of the view that content externalism and epistemic internalism are, in fact, compatible after all.2 Our aim here is twofold. First, to show that Chase is only able to achieve this result because he focuses upon the internalist conception of justification, rather than knowledge. Second, to formulate one prima facie argument which shows that an internalist conception of knowledge is incompatible with an externalist conception of content, an argument which, moreover, is not touched by Chase.

Dworkin's theoretical disagreement argument, developed in Law's Empire, is presented in that work as the motivator for his interpretive account of law. Like Dworkin's earlier arguments critical of legal positivism, the argument from theoretical disagreement has generated a lively exchange with legal positivists. It has motivated three of them to develop innovative positivist positions. In its original guise, the argument from theoretical disagreement is presented as ‘the semantic sting argument’. However, the argument from theoretical disagreement has more than one (...) version. This article briefly discusses two versions and the leading replies to them, then focuses on the most influential version, directed at Hartian positivism. The article surveys the leading positivist rejoinders to the recast version, indicating key Dworkinian replies or assessing the strength of these rejoinders, and concludes with a rejoinder of its own, making a new case that the argument from theoretical disagreement isn't fatal for Hartian legal positivism.

The ' argument from queerness', made famous by J. L. Mackie, remains one of the most influential arguments in metaethics. However, many philosophers focus on just one or two of its strands, while others assume a particular but by no means universal reading of it.

Much of the argument collapses into other (...) types of argument, and what is left, though intuitively appealing, is not viable as philosophical argument. (shrink)

There are at least three different genealogical accounts of morality: the ontogenetic, the sociohistorical, and the evolutionary. One can thus construct, in principle, three distinct genealogical debunking arguments of morality, i.e., arguments that appeal to empirical data, or to an empirical hypothesis, about the origin of morality to undermine either its ontological foundation or the epistemic credentials of our moral beliefs. The genealogical account that has been, particularly since the early 2000s, the topic of a burgeoning line of (...) inquiry in the metaethical literature is the one that explains the origin of moral thinking by appealing to Charles Darwin’s theory of evolution through natural selection. For this reason, when it comes to genealogical debunking arguments, it is various types of evolutionary debunking argument (EDA) that are the focus of the current debate between moral skeptics and moral realists. Evolutionary moral debunkers maintain that the capacity to make moral judgments is an evolved trait—a view accepted by most of their detractors. They maintain, in addition, that such a capacity is an adaptation—i.e., a trait selected for because it enhances reproduction and survival—and not merely either a by-product of an adaptation or an evolutionary accident—a view accepted by fewer of their detractors. Roughly put, the thrust of EDAs is that biological evolution is aimed, not at moral belief-forming processes that are reliable, but at moral belief-forming processes that are adaptive. In other words, the evolutionary function of those processes is not that of tracking the moral truth: their general success at matching or accurately representing allegedly objective or attitude-independent moral facts, properties, or truths explains neither their emergence nor their persistence. Humans are therefore disposed to make moral judgments regardless of the evidence to which they are exposed, regardless of whether there are or are not objective moral facts, properties, or truths. In the contemporary scene, the most important and influential EDAs are those advanced by Richard Joyce and Sharon Street. Although Joyce’s EDA is more elaborate than Street’s inasmuch as it is based on a detailed evolutionary account of morality, it is Street’s EDA that has received the most attention among those seeking to defend moral realism against EDAs. If an EDA can establish at most an epistemological conclusion, then it could be argued that Joyce’s argument (at least the version defended in his later works) is superior to Street’s given that the conclusion of the former is epistemological whereas that of the latter is ontological. Indeed, while Joyce’s EDA is taken to support epistemological moral skepticism, according to which our moral beliefs are epistemically unjustified, Street’s is taken to support moral anti-realism (moral constructivism in particular), according to which attitude-independent moral facts do not exist.

If the most familiar overlapping interpretation of Everettian quantum mechanics is correct, then each of us is constantly splitting into multiple people. This consequence gives rise to the quantum doomsday argument, which threatens to draw crippling epistemic consequences from EQM. However, a diverging interpretation of EQM undermines the quantum doomsday argument completely. This appears to tell in favour of the diverging interpretation. But it is surprising that a metaphysical question that is apparently underdetermined by the physics should be settled by (...) purely epistemological considerations; and I argue that the positive case for divergence based on the quantum doomsday effect is ultimately unsuccessful. I discuss how some influential treatments of Everettian confirmation handle the quantum doomsday puzzle, and suggest that it can most satisfyingly be resolved via a naturalistic approach to the metaphysics of modality.

In Reason, Truth and History, Putnam provides an influential argument for the materialist view that the supposition that we are all “actually” brains in a vat [BIV’s] is “necessarily false”. Putnam admits that his argument, inspired by insights in Wittgenstein’s later views, is “unusual”, but he is certain that it is a correct. He argues that the claim that we are BIV’s is self-refuting because, if we actually are BIV’s, then we cannot refer to real physical things like vats. (...) Although the present author agrees, fundamentally, with Heidegger’s view that we are essentially “in a world”, and, therefore, with Putnam’s conclusion that we cannot possibly be BIV’s, the paper argues that Putnam’s argument is fallacious. The proper conclusion to draw from Putnam’s argument is that asserting that one is a BIV is beyond the limits of a BIV’s language. That is, Putnam only shows that if we actually are BIV’s, then we cannot think or assert either that we are or that we are not BIV’s. It does not show that we are not “actually” BIV’s. The cogency of this criticism is illustrated with a concrete “science-fiction” example. (shrink)

Peter van Inwagen's influential Direct Argument (DA) for the incompatibility of moral responsibility and causal determinism makes use of an inference rule he calls "Rule B." Michael McKenna has argued that van Inwagen's defense of this rule is dialectically inappropriate because it is based entirely on alleged “confirming” cases that are not of the right kind to justify the use of Rule B in DA. Here I argue that McKenna’s objection is on the right track but more must be (...) said if we are to see why. To fill in the gaps I consider a recent attempt by Ira M. Schnall and David Widerker to defend DA against McKenna’s objection. I argue that neither prong of their attack is successful against a variation on McKenna’s basic argument. In the course of responding to Schnall and Widerker’s objections to McKenna, I identify what is, as I argue, the real reason DA fails in its purpose to shift the burden of proof. (shrink)

Argues against several influential a priori arguments for individualism in the philosophy of mind that were influential in the 1980s.

The consequence argument is a powerful incompatibilist argument for the conclusion that, if determinism is true, what one does is what one must do. A major point of controversy between classical compatibilists and incompatibilists has been over the use of ‘can’ in the consequence argument. Classical compatibilists, holding that abilities to act are dispositions, have argued that ‘can’ should be analyzed as a conditional. But such an analysis of ‘can’ puts compatibilists in a position to grant the premises of the (...) argument while denying the conclusion. Incompatibilists remain unconvinced, and this corner of the debate over free will has reached a dialectical impasse. The present paper has two aims. First, to offer a new dialectical point of entry into this dispute on behalf of incompatibilists. By making use of Angelika Kratzer's influential semantic work on ‘can’ and ‘must’, I argue that incompatibilists are in a position to offer a plausible, positive treatment of ‘can’ that favors their view. Second, even if one does not think incompatibilism is thereby true (for as we shall see there are places to push back), the Kratzer semantics yields a number of important insights concerning the consequence argument that should be of broad interest.

Here I respond to Anthony Brueckner and John Martin Fischer’s “The Evil of Death: A Reply to Yi.” They developed an influential strategy in defense of the deprivation account of death’s badness against the Lucretian symmetry problem. The core of their argument consists in the claim that it is rational for us to welcome future intrinsic goods while being indifferent to past intrinsic goods. Previously, I argued that their approach is compatible with the evil of late birth insofar as (...) an earlier birth would have generated more goods in the future. In reply, Brueckner and Fischer argue that my critique fails to appreciate an important aspect of their thought experiment, which aims only to show that the deprivation of past goods per se is not bad for us. Thus, purportedly, my critique poses no threat to their view. Here I argue that since the deprivation account explains the evil of death with recourse to how one’s life would have fared had one lived longer, it ought to respond to the symmetry problem with reference to how one’s life would have fared had one been born earlier. However, it is not generally true that the life one would have had with an earlier birth is not preferable to one’s actual life, because in many cases such a life would contain more future goods.

In God and Phenomenal Consciousness, Yujin Nagasawa bridges debates in two distinct areas of philosophy: the philosophy of mind and the philosophy of religion. First, he introduces some of the most powerful arguments against the existence of God and provides objections to them. He then presents a parallel structure between these arguments and influential arguments offered by Thomas Nagel and Frank Jackson against the physicalist approach to phenomenal consciousness. By appealing to this structure, Nagasawa constructs novel (...) objections to Jackson's and Nagel's arguments. Finally, he derives, from the failure of these arguments, a unique metaphysical thesis, which he calls 'non-theoretical physicalism'. Through this thesis, he shows that although this world is entirely physical, there are physical facts that cannot be captured even by complete theories of the physical sciences. (shrink)

One of the most influential arguments for the coherence theory of empirical justification is BonJours a priori argument from the internalist regress. According to this argument, foundationalism cannot solve the problem of the internalist regress since internalism is incompatible with basic beliefs. Hence, coherentism seems to be the only option. In my article I contend that this argument is doomed to failure. It is either too strong or too weak. Too strong, since even coherentism cannot stop the internalist (...) regress in any legitimate way. In order to demonstrate this claim I will discuss various coherentist strategies. Too weak, since, were coherentism able to stop the regress, the argument against foundationalism would collapse. (shrink)
