What is the nature of the evidence provided by thought experiments in philosophy? For instance, what evidence is provided by the Gettier thought experiment against the JTB theory of knowledge? According to one view, it provides as evidence only a certain psychological proposition, e.g. that it seems to one that the subject in the Gettier case lacks knowledge. On an alternative, nonpsychological view, the Gettier thought experiment provides as evidence the nonpsychological proposition that the subject in the Gettier case lacks (...) knowledge (e.g., Williamson 2007). Given the centrality of thought experiments to philosophical enquiry, the correct account of thought experiment evidence is important for understanding the nature of philosophical methodology. Further, Williamson argues that a misguided adherence to the psychological view of thought experiment evidence encourages scepticism about philosophy since it opens a gap between our evidence and the nonpsychological subject matter of philosophy. The main aim of this paper is to defend the psychological view against recent objections. In particular, I argue that even if thought experiment evidence is psychological, it can still provide justification for non-psychological claims which are the subject matter of philosophy. (shrink)

Many philosophers accept a view – what I will call the intuition picture – according to which intuitions are crucial evidence in philosophy. Recently, Williamson has argued that such views are best abandoned because they lead to a psychologistic conception of philosophical evidence that encourages scepticism about the armchair judgements relied upon in philosophy. In this paper I respond to this criticism by showing how the intuition picture can be formulated in such a way that: it is consistent with a (...) wide range of views about not only philosophical evidence but also the nature of evidence in general, including Williamson's famous view that E = K; it can maintain the central claims about the nature and role of intuitions in philosophy made by proponents of the intuition picture; it does not collapse into Williamson's own deflationary view of the nature and role of intuitions in philosophy; and it does not lead to scepticism.

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that moral sentences have truth-value, there are moral properties that make some moral sentences true, and moral properties are not reducible to non- moral properties. Realism is contrasted with non-cognitivism, error-theory and reductionism, which, in brief, deny, and, respectively. In the introductory chapter, it is also argued that there are some prima facie reasons to assume (...) that non-cognitivism and error-theory are erroneous. In chapters 2 and 3, I suggest that the two main forms of reductionism, analytic and synthetic reductionism, are mistaken. In chapter 4, I argue that the considerations in the previous chapters in relation to non-cognitivism, error-theory and reductionism provide support to moral realism. It is also suggested that these considerations make it plausible to hypothesise that moral properties depend on non- moral properties in a way I refer to as ‘the realist formula’. The realist formula confirms moral realism since it implies that moral properties are not reducible to non- moral properties. In chapters 5, 6 and 7, I argue that moral realism, much owing to the realist formula, is able to explain significant meta-ethical issues regarding moral disagreement, moral reason and moral motivation. Among other things, externalism concerning moral motivation is defended. The explanatory value of moral realism in relation to these meta-ethical issues is taken to suggest that this view is preferable to non-cognitivism, error-theory and reductionism. Some of the meta-ethical issues discussed in these chapters, particularly moral disagreement and motivation, have been thought to provide support to non-cognitivism and error-theory. I maintain that since realism, unlike reductionism, is able to counter these arguments, it justifies us in upholding the view that moral sentences have truth-value and the view that there are moral properties. In chapter 8, various objections against realism with regard to the dependence of moral properties on non- moral properties are responded to. In chapter 9, I consider an influential argument to the effect that moral properties are not involved in causal explanations. I maintain that this argument fails and that it therefore is reasonable to assume that moral properties are natural properties. However, the discussions in chapters 8 and 9 also suggest that moral realism might face problems that cannot be thoroughly discussed in this thesis. (shrink)

Advocates of the use of intuitions in philosophy argue that they are treated as evidence because they are evidential. Their opponents agree that they are treated as evidence, but argue that they should not be so used, since they are the wrong kinds of things. In contrast to both, we argue that, despite appearances, intuitions are not treated as evidence in philosophy whether or not they should be. Our positive account is that intuitions are a subclass of inclinations to believe. (...) Our thesis explains why intuitions play a role in persuasion and inquiry, without conceding that they are evidential. The account also makes predictions about the structure of intuitions that are confirmed by independent arguments. (shrink)

Someone who knew everything about the world’s physical nature could, apparently, suffer from ignorance about various aspects of conscious experience. Someone who knew everything about the world’s physical and mental nature could, apparently, suffer from moral ignorance. Does it follow that there are ways the world is, over and above the way it is physically or psychophysically? This paper defends a negative answer, based on a distinction between knowing the fact that p and knowing that p. This distinction is made (...) intelligible by reference to criterial connections between the possession of moral or phenomenal knowledge, and the satisfaction of cognitively neutral conditions of desire and experiential history. The existence of such connections in the moral case makes for an efficient dissolution of the so-called moral problem. (shrink)

A number of philosophers have recently suggested that the role of intuitions in the epistemology of armchair philosophy has been exaggerated. This suggestion is rehearsed and endorsed. What bearing does the rejection of the centrality of intuition in armchair philosophy have on experimentalist critiques of the latter? I distinguish two very different kinds of experimentalist critique: one critique requires the centrality of intuition; the other does not.

For moral realists moral judgments will be a kind of factual judgment that involves the basically reliable apprehension of an objective moral reality. I argue that factual judgments display at least some degree of conceptual sensitivity to error, while moral judgments do not. Therefore moral judgments are not a kind of factual judgment.

My first paper on the Is/Ought issue. The young Arthur Prior endorsed the Autonomy of Ethics, in the form of Hume’s No-Ought-From-Is (NOFI) but the later Prior developed a seemingly devastating counter-argument. I defend Prior's earlier logical thesis (albeit in a modified form) against his later self. However it is important to distinguish between three versions of the Autonomy of Ethics: Ontological, Semantic and Ontological. Ontological Autonomy is the thesis that moral judgments, to be true, must answer to a realm (...) of sui generis non-natural PROPERTIES. Semantic autonomy insists on a realm of sui generis non-natural PREDICATES which do not mean the same as any natural counterparts. Logical Autonomy maintains that moral conclusions cannot be derived from non-moral premises.-moral premises with the aid of logic alone. Logical Autonomy does not entail Semantic Autonomy and Semantic Autonomy does not entail Ontological Autonomy. But, given some plausible assumptions Ontological Autonomy entails Semantic Autonomy and given the conservativeness of logic – the idea that in a valid argument you don’t get out what you haven’t put in – Semantic Autonomy entails Logical Autonomy. So if Logical Autonomy is false – as Prior appears to prove – then Semantic and Ontological Autonomy would appear to be false too! I develop a version of Logical Autonomy (or NOFI) and vindicate it against Prior’s counterexamples, which are also counterexamples to the conservativeness of logic as traditionally conceived. The key concept here is an idea derived in part from Quine - that of INFERENCE-RELATIVE VACUITY. I prove that you cannot derive conclusions in which the moral terms appear non-vacuously from premises from which they are absent. But this is because you cannot derive conclusions in which ANY (non-logical) terms appear non-vacuously from premises from which they are absent Thus NOFI or Logical Autonomy comes out as an instance of the conservativeness of logic. This means that the reverse entailment that I have suggested turns out to be a mistake. The falsehood of Logical Autonomy would not entail either the falsehood Semantic Autonomy or the falsehood of Ontological Autonomy, since Semantic Autonomy only entails Logical Autonomy with the aid of the conservativeness of logic of which Logical Autonomy is simply an instance. Thus NOFI or Logical Autonomy is vindicated, but it turns out to be a less world-shattering thesis than some have supposed. It provides no support for either non-cognitivism or non-naturalism.

Discussion of moral explanation has reached an impasse, with proponents of contemporary ethical naturalism upholding the explanatory integrity of moral facts and properties, and opponents--including both antirealists and non-naturalistic realists--insisting that such robustly explanatory pretensions as moral theory has be explained away. I propose that the key to solving the problem lies in the question whether instances of moral properties are causally efficacious. It is argued that, given the truth of contemporary ethical naturalism, moral properties are causally efficacious if the (...) properties of the special sciences are. (shrink)

Moral error theorists face the now what question. How, if at all, ought they to adjust their moral practice after having discovered the error? Various answers have emerged in the literature, including, but not limited to, revisionary fictionalism, revisionary expressivism, and revisionary naturalism. Recently, François Jaquet has argued that there are only two available answers to the now what question, since every extant answer except revisionary fictionalism collapses into abolitionism. This paper provides a response. First, it argues that revisionary naturalism (...) does not collapse into abolitionism. The argument is that abolitionists can neither utter schmoralist naturalist replacement judgments that contain moral terms nor eliminativist naturalist replacement judgments that do not contain moral terms. This means that abolitionists cannot utter replacement judgments at all. Since revisionary naturalists can utter replacement judgments, their view does not collapse into abolitionism. Second, the paper gives reason to believe that this result extends beyond revisionary naturalism to the other revisionary metaethical theories, and that this is good news for moral error theory.

Moral realism and ethical naturalism are both highly attractive ethical positions but historically they have often been thought to be irreconcilable. Since the late 1980s defenders of Cornell Realism have argued that the two positions can consistently be combined. They make three constitutive claims: (i) Moral properties are natural kind properties that (ii) are identical to (or supervene) on descriptive functional properties, which (iii) causally regulate our use of moral terms. We offer new arguments against the feasibility of Cornell realism (...) and then show that there is a way to be a naturalistic realist that avoids internal inconsistency and uniquely provides for moral normativity.

My aim is to challenge recent attempts at reconciling moral realism and naturalism by pushing ethical naturalists into a dilemma. According to one horn of the dilemma, ethical naturalists must either build unique facts and properties about divergent social structures into their subvenient sets of natural facts and properties, and so jeopardize the objectivity of moral truths, or insist, in the face of all possible worlds in which people have different moral beliefs than ours, that they are all mistaken—this despite (...) the fact that the belief-forming mechanism responsible for their moral beliefs was never concerned with the truth of those beliefs in the first place. This will bring me to suggest that moral properties might only weakly supervene upon natural phenomena. But, according to the other horn of the dilemma, weak supervenience is a defeater for moral knowledge. (shrink)

Moral epistemology (henceforth ME) has been spoken of as a subject matter in its own right by philosophers in the last few decades and yet the delineation of ME as a sub-discipline remains uncharted. Many eminent scholars with rich contributions have not explicitly defined the scope or demarcation of this emerging field. Drawing from their writings, the paper tries to show that philosophers working on ME either conceptualise it as an application of epistemology to moral beliefs or as encompassing issues (...) of epistemic access to moral truths. The paper contends that such conceptions of moral epistemology are not rigorous enough to warrant a discrete sub-discipline. This puts the paper in disagreement with those scholars who justify the creation of a subject-specific ME. David Copp and Todd Stewart figure prominently among such attempts. Copp and Stewart justify ME to be a separate epistemology, by alluding to the normative nature of moral beliefs, and through the introduction of emotions into the mix, respectively. The paper tries to show that neither normativity nor emotions appear to be robust enough to create a distinct epistemology. The predicament of moral epistemologists arises from the fact that while the practitioners seem to be keen on establishing ME as a discrete sub-discipline, they end up subsuming it under a general epistemology and fail to justify the need for such a subject-specific epistemology. The only way out of this quandary, the paper asserts, is to treat ME more as a methodological project that involves extending general epistemic tools to moral beliefs as a specific case, and not as a specialised topic-specific epistemology.

Empirical findings about intuitions putatively cast doubt on the traditional methodology of philosophy. Herman Cappelen and Max Deutsch have argued that these methodological concerns are unmotivated as experimental findings about intuitions are irrelevant for assessments of the methodology of philosophy—I dub this the ‘Irrelevance Claim’. In this paper, I first explain that for Cappelen and Deutsch to vindicate the Irrelevance Claim from a forceful objection, their arguments have to establish that intuitions play no epistemically significant role whatsoever in philosophy—call this (...) the ‘Orthogonality Claim’. I then argue that even under a charitable reading of their views Cappelen and Deutsch fail to establish the Orthogonality Claim. Lastly, I discuss empirical evidence that the Orthogonality Claim is false. The arguments in this paper will demonstrate that Cappelen and Deutsch cannot motivate the Irrelevance Claim and that their replies to recent experimental attacks on traditional methodology of philosophy do not succeed.

Moral anti-realism comes in two forms – noncognitivism and the error theory. The noncognitivist says that when we make moral judgments we aren’t even trying to state moral facts. The error theorist says that when we make moral judgments we are making statements about what is objectively good, bad, right, or wrong but, since there are no moral facts, our moral judgments are uniformly false. This development of moral anti-realism was first seriously defended by John Mackie. In this paper I (...) explore a dispute among moral error theorists about how to deal with false moral judgments. The advice of the moral abolitionist is to stop making moral judgments, but the contrary advice of the moral fictionalist is to retain moral language and moral thinking. After clarifying the choice that arises for the moral error theorist, I argue that moral abolitionism has much to recommend it. I discuss Mackie’s defense of moral fictionalism as well as a recent version of the same position offered by Daniel Nolan, Greg Restall, and Caroline West. Then I second some remarks Ian Hinckfuss made in his defense of moral abolitionism and his criticism of “the moral society.” One of the worst things about moral fictionalism is that it undermines our epistemology by promoting a culture of deception. To deal with this problem Richard Joyce offers a “non-assertive” version of moral fictionalism as perhaps the last option for an error theorist who hopes to avoid moral abolitionism. I discuss some of the problems facing that form of moral fictionalism, offer some further reasons for adopting moral abolitionism in our personal lives, and conclude with reasons for thinking that abolishing morality may be an essential step in achieving the goals well-meaning moralists and moral fictionalists have always cherished.

Philosophy of Mind is suitable for students at all levels and also for general readers. (shrink)

The effects of anthropogenic climate change may be devastating. Nevertheless, most people do not seem to be seriously concerned. We consume as much as we always did, drive as much as we always did, eat as much meat as we always did. What can we do to overcome this collective apathy? In order to be able to develop effective measures, we must first get clear about the causes of climate change inaction. In this paper I ask whether moral nihilism is (...) a significant cause of climate change inaction. The answer to this question depends mainly on the extent to which being a moral nihilist reduces one's likelihood of taking action against climate change. At first sight, the extent seems to be considerable. I argue, however, that this assumption is false. Only slightly more non-nihilists than nihilists are led to climate-friendly actions by moral considerations. And in absolute terms, morality plays such a minor role in leading people to act that the difference is barely noticeable. (shrink)

Though most of analytic philosophy is based upon intuitions, some philosophers are beginning to question whether intuitions are an appropriate basis for philosophical theory. This paper responds to the arguments of some contemporary philosophers who hold that intuitions should not be treated as evidence for anything other than our contingent psychological constitution. It begins with a demonstration that skeptical arguments by Gilbert Harman and Alvin Goldman are variations on an argument with the potential to undermine the use of intuitions in (...) much philosophical inquiry. After a demonstration that Nicholas Sturgeon’s response to Harman’s argument is inadequate, it argues that all of the instances of the skeptical argument are unsuccessful because they are epistemically self-defeating.

ABSTRACTThe article uses the recent U.S. Supreme Court decision in the same-sex marriage caseObergefell v. Hodgesas the springboard for a general enquiry into the nature and existence of a constitutional right to liberty under the American Constitution. The discussion is divided into two main parts. The first examines the meaning and the justifiability of there being a moral right to liberty as a matter of political philosophy. Two such rights are distinguished and defended: first, a right not to be coerced (...) by the state when the state is motivated by improper reasons ; and second, a right not to be coerced by the state when there are insufficient justifying reasons for the state to do so, irrespective of how such state coercion may be motivated. Neither right is regarded as “absolute,” and so it is morally permissible for the state to override such rights in certain circumstances. The second part of the article examines the distinct and additional considerations that must be taken into account when these two moral rights to liberty are fashioned into corresponding legal rights under American constitutional law. Both such rights survive the transformation, but each becomes altered somewhat in its content. This legal transformation includes recognition of the nonabsolute nature of moral rights, such recognition taking the form of some doctrine of “compelling state interests.” The discussion in these two main parts of the article is prefaced with a defense of the article's use of political philosophy to inform constitutional law, a defense motivated by Chief Justice Robert's denunciation of such an approach to constitutional law in his opinion inObergefell.

I examine the debate between reductive and non-reductive physicalists, and conclude that if we are to be physicalists, then we should be reductive physicalists. I assess how both reductionists and non-reductionists try to solve the mind-body problem and the problem of mental causation. I focus on the problem of mental causation as it is supposed to be faced by non-reductionism: the so-called overdetermination problem. I argue that the traditional articulation of that problem is significantly flawed, and I show how to (...) articulate it properly: what I call the ‘super-overdetermination problem’. In doing so, I demonstrate that the problem of mental causation faced by non-reductionism is in fact a special case of the mind-body problem, as faced by non-reductionism, and that the former can’t be solved independently of the latter. I then assess the prospects for a particular family of non-reductive views that I call immanentism, and show that they fail to solve the super-overdetermination problem. Finally, I put forward two arguments to support the conclusion that physicalism entails reductionism. Both arguments establish, via distinct reasoning, the proposition that mental property instances are identical to physical property instances; and then each argument employs the inference, which I also defend, that if mental instances are physical instances, then mental properties are physical properties; hence, reductionism follows.

It seems to be generally agreed that a foundationalist view of any area of justified beliefs is the affirmation that there are some beliefs which are to some degree credible for a person independently of reflection on logical relations to any others of his beliefs, and that any other beliefs of his are justified because of appropriate logical relations to these basic beliefs — thus contrary to the coherentist thesis that beliefs can only be justified by appeal to their relation (...) to other beliefs of a person, independently of whether these other beliefs are themselves independently credible. Thus, for the area of moral beliefs, foundationalism is the view that there is at least a subset of a person's moral beliefs which are either justified independently of logical relations to any other beliefs, or are justified by their logical relations to some other beliefs, either independently credible moral beliefs, or independently credible non-moral ones.I am here restricting ‘ethical’ beliefs to moral beliefs, as distinct from beliefs that something is a good thing or intrinsically good or good for a person.

Predmet ovog rada je vjerojatno najutjecajnija verzija moralnog realizma, poznata kao “moralni realizam naturalizam”.

Often, the deepest disagreements are about starting points, and which considerations are relevant.

According to the social ontology proposed by John Searle, there are ontologically objective facts or “brute facts”, independent from human attitudes, and ontologically subjective facts. Among the latter, the most notable are institutional facts, such as money or borders, which existence is explained through a collective attribution of status function within a certain social context. Could “moral truths” exist according to an ontology like this? Assuming the truth as correspondence, the notion of “moral truth” remits to the notion of “moral (...) fact”. As we will see, these moral facts, contrary to what authors such as Markus Gabriel suggest, are similar to institutional facts. For this reason, the truth or falsity of moral statements will be, as indicated by authors such as Gilbert Harman, relative to a social context; without that being an obstacle for acknowledging their expressive and directive function.

Experimental philosophers have recently conducted surveys of folk judgements about a range of phenomena of interest to philosophy including knowledge, reference, and free will. Some experimental philosophers take these results to undermine the philosophical practice of appealing to intuitions as evidence. I consider several different replies to the suggestion that these results undermine philosophical appeal to intuition, both piecemeal replies which raise concerns about particular surveys, and more general replies. The general replies include the suggestions that the surveys consider the (...) wrong sort of judgement, or the wrong kind of judge, or that the results of the surveys do not generate scepticism about philosophical appeal to intuition in particular, but rather a more problematic and general scepticism. I argue that the last of these general replies is the most promising. To assess its merits, I consider the most developed account of how the survey results are supposed to raise sceptical problems specifically for philosophical appeal to intuition, that presented in Weinberg (Midwest Stud Philos XXXI:318–343, 2007). I argue that there are significant objections to Weinberg’s account. I conclude that, so far, experimental philosophers have failed to show how their survey results raise a sceptical challenge that applies to philosophical appeal to intuition in particular, rather than having a problematic, more general scope.

Many commentators suppose that morality, objectively construed, must possess a minimal sort of explanatory relevance if moral realism is to be plausible. To the extent that moral realists are unable to secure explanatory relevance for moral facts, moral realism faces a problem. Call this general objection an “explanatory objection” to moral realism. Despite the prevalence of explanatory objections in the literature, the connection between morality’s explanatory powers and moral realism’s truth is not clear. This paper considers several different reasons for (...) subjecting morality to explanatory scrutiny and concludes that none of them uncover a special or compelling explanatory problem for realism. In light of these difficulties, an alternative account of the connection between moral realism and moral explanation is developed. Not only does this account make sense of explanatory objections to realism, it turns out that realists may have the resources to defend themselves against this explanatory concern, properly understood.
