The article discusses the personality and legacy of Derek Parfit. he entered the history of modern metaphysics and moral philosophy as a proponent of radical neo-lockean view on the issues of personal identity. denying our basic metaphysical and moral intuitions (identity for the person and moral responsibility), the so-called «Oxford buddhist» was a tireless preacher of hyper-rational altruism. his original ideas and admirable arguments outlined only in few works were and remain at the center of philosophical discussions.

This is a brief summary of some objections.

Derek Parfit argues that everyone ought to follow the principles whose universal acceptance would make things go best. I present a counterexample: a world in which no one's moral beliefs have any motivating force. I explain how Parfit's metaethical commitments imply that such a world is possible, and why this possibility is a problem for Parfit's project of reconciling Kantianism, contractualism, and consequentialism. I consider two of Parfit's responses to my counterexample.

Derek Parfit argues in Reasons and Persons that acting according to your present desires is more rational, or at least as rational, as acting in your long-term self-interest. To do this, he puts forward a case supporting a 'critical present-aim theory' of rationality opposed to the self-interest theory, and then argues against a number of possible replies. This article is a response to these arguments, concluding that Parfit's favouring of the present-aim theory is unfounded, and that self-interest (...) is the better theory of rationality. (shrink)

In his discussion of normative concepts in the first part of On What Matters (2011), Parfit holds that apart from the ‘ought’ of decisive reason, there are other senses of ‘ought’ which do not imply any reasons. This claim poses a dilemma for his ‘reason-involving conception’ of normativity: either Parfit has to conclude that non-reason-implying ‘oughts’ are not normative. Or else he is forced to accept that normativity needs only to involve ‘apparent reasons’ – a certain kind of (...) hypothetical truths about reasons. I argue that both of these options are inacceptable. In the course of the discussion, I present a general objection to ‘apparent reason accounts’ of the normativity of rationality as advocated not only by Parfit, but also by Schroeder (2009) and Way (2009). (shrink)

The paper takes a close look at Derek Parfit’s example of the Nineteenth Century Russian in 'Reasons and Persons'. Parfit presents it as an example which illustrates the moral consequences of adopting his reductionist view of personal identity in a positive light. I argue that things turn out to be more complex than he envisages, and that it might be far more difficult to live in his world than he allows.

Derek Parfit, in On What Matters, argues that all subjective accounts of normative reasons for action are false. This chapter focuses on his “Agony Argument.” The first premise of the Agony Argument is that we necessarily have current reasons to avoid our own future agony. Its second premise is that subjective accounts cannot vindicate this fact. So, the argument concludes, subjective accounts must be rejected. This chapter accepts the first premise of this argument and that it is valid. (...) The main thesis of this chapter is that subjectivists can account for our reasons to get pleasure and avoid agony. The chapter concludes that the Agony Argument does not justify the rejection of subjective accounts. The chapter also examines Parfit's understanding of the distinction between objective and subjective theories. The chapter claims Parfit offers a surprisingly narrow understanding of subjectivism such that even if his critique were successful, this would be bad news for fewer theories than we might have thought. Finally, the chapter replies to some possible worries about the arguments of this chapter. (shrink)

In his early works, Derek Parfit famously defended revisionary reductionism about personhood. According to this view, facts about personal identity consist in the holding of more particular psychological facts, which can be described wholly impersonally. He also argued that, in some cases, the truth of this view makes questions about diachronic personal identity empty questions to which no meaningful answers can be given. Yet, in his later works, Parfit defends several ethical theories such as contractualism and rule-consequentialism, (...) which seem to rely on exactly the kind of determinate notion of personal identity to which he objected earlier. Parfit, furthermore, never explored reductionism’s consequences for such theories in his later works. In order to solve this interpretative puzzle, this chapter tries to argue that, even if they are seemingly conflicting, Parfit’s views on personal identity and rule-consequentialism, Scanlonian contractualism, and Kantian contractualism do form a coherent and unified whole.

Derek Parfit was one of the most important and influential moral philosophers of the late 20th and early 21st centuries. This Element offers a critical introduction to his wide-ranging ethical thought, focusing especially on his two most significant works, Reasons and Persons and On What Matters, and their contribution to the consequentialist moral tradition. Topics covered include: rationality and objectivity, distributive justice, self-defeating moral theories, Parfit's Triple Theory, personal identity, and population ethics.

This paper presents a Davidsonian perspective on Derek Parfit’s disagreements with Nietzsche. I have actually gone further, too far perhaps, and tried to imitate Davidson’s attractive essayistic style.

The article presents a critical analysis of views on the problem of personal identity which are proposed by two great English philosophers — John Locke and Derek Parfit. Lockean personality is considered as a basic metaphysical structure, subject to moral responsibility for all actions performed on its behalf. Parfitian personality, in contrast, denies any identical essence through time as an extremely improbable metaphysical structure, instead assuming an existential chain of one life’s stages with psychological continuity. As an alternative (...) to these views, a several of additional arguments are considered to support the physicist view of human nature. (shrink)

Metaethical non-analytical naturalism consists in the metaphysical thesis that normative properties are identical with or reducible to natural properties and the epistemological thesis that we cannot come to a complete understanding of the nature of normative properties via conceptual analysis alone. In On What Matters, Derek Parfit (2011) argues that non-analytical naturalism is either false or incoherent. In § 1, I show that his argument for this claim is unsuccessful, by showing that it rests on a tacit assumption (...) about the nature of normative thought that non-analytical naturalists need not accept. In § 2, I show that escaping Parfit’s argument in this way is no ad hoc maneuver; as I demonstrate, the idea that non-analytical naturalists can exploit to escape Parfit’s argument is a familiar one. (shrink)

In the posthumously published ‘Future People, the Non-Identity Problem, and Person-Affecting Principles’, Derek Parfit presents a novel axiological principle which he calls the Wide Dual Person-Affecting Principle and claims that it does not imply the Repugnant Conclusion. This paper shows that even the best version of Parfit's principle cannot avoid this conclusion. That said, accepting such a principle makes embracing the Repugnant Conclusion more justifiable. This paper further addresses important questions which Parfit left unanswered concerning: the (...) relative importance of individual and collective goodness, comparisons involving unequal outcomes, how to understand individual goodness, and whether incomparability at the level of individual goodness implies incomparability at the level of overall goodness. (shrink)

I argue that rule consequentialism sometimes requires us to act in ways that we lack sufficient reason to act. And this presents a dilemma for Parfit. Either Parfit should concede that we should reject rule consequentialism (and, hence, Triple Theory, which implies it) despite the putatively strong reasons that he believes we have for accepting the view or he should deny that morality has the importance he attributes to it. For if morality is such that we sometimes have (...) decisive reason to act wrongly, then what we should be concerned with, practically speaking, is not with the morality of our actions, but with whether our actions are supported by sufficient reasons. We could, then, for all intents and purposes just ignore morality and focus on what we have sufficient reason to do, all things considered. So if my arguments are cogent, they show that Parfit’s Triple Theory is either false or relatively unimportant in that we can, for all intents and purposes, simply ignore its requirements and just do whatever it is that we have sufficient reason to do, all things considered.

Figure majeure de la philosophie morale, Derek Parfit (1942-2017) reste encore peuconnu en France. Cette introduction vise à montrer l'ampleur des thématiques abordées de Parfit en les rattachant au projet d'une éthique rationnelle, tandis que le numéro dansson ensemble, sans prétendre être exhaustif, propose des présentations et discussions de différents éléments clefs de sa philosophie.

Though famously Derek Parfit is known for his reductionism about persons, he does, in fact, also profess a form of realism about persons based on the way the language of persons and personal identity is used. We might say that Parfit is an ontological reductionist about persons but not a conceptual reductionist. In this discussion note I try to bring out a difficulty for this kind of hybrid view by showing that there are many ways – too (...) many in fact – in which we use the language of persons and personal identity that cannot be reconciled with the core of Parfitian ontological reductionism. If it is true that the kind of reconciliation Parfit and his followers assent to is untenable, then a stark choice is presented between reductionism and a repudiation of most, if not all vestiges of realism. A genuine reductionist ought to choose against the latter. (shrink)

In his book On What Matters, Derek Parfit defends a version of moral non-naturalism, a view according to which there are objective normative truths, some of which are moral truths, and we have a reliable way of discovering them. These moral truths do not exist, however, as parts of the natural universe nor in Plato’s heaven. While explaining in what way these truths exist and how we discover them, Parfit makes analogies between morality on the one hand, (...) and mathematics and logic on the other. Moral truths “exist” in a way that numbers exist, and we discover these truths in a similar way as we discover truths about numbers. By the end of the second volume, Parfit also responds to a powerful objection against his view, an objection based on the phenomenon of moral disagreement. If people widely and deeply disagree about what is the moral truth, it is doubtful whether we have a reliable way of discovering it. In his reply, he claims that in ideal conditions for thinking about moral questions, we would all have sufficiently similar moral beliefs. However, we often find ourselves in less-than-ideal conditions due to various factors that distort our ability to agree. Therefore, differences in moral opinion can be expected. In this paper, I draw a connection between these parts of Parfit’s theory and comment on them. Firstly, I argue that Parfit’s analogy with mathematics and logic and his answer to the disagreement objection are in tension because there are important epistemic differences between morality and these fields. If one would try to account for the differences, one would have to sacrifice some measure of similarity between morality and them. Secondly, I comment on Parfit’s reply to the disagreement objection itself. I believe that, although his description of ideal conditions has some potential for reaching moral agreement, it may be difficult to tell if ideal conditions prevail. This obscurity spells further trouble for Parfit’s overall theory. (shrink)

A *very* rough draft of a paper on Anselm's "ontological argument" in which I argue that the argument in the Proslogion rests on a robust notion of having "that then which nothing greater can be thought" in one's mind.

This paper weaves together a number of separate strands each relating to an aspect of Wittgenstein’s Philosophical Investigations. The first strand introduces his radical and incoherent idea of a private object. Wittgenstein in § 258 and related passages is not investigating a perfectly ordinary notion of first person privacy; but his critics have treated his question, whether a private language is possible, solely in terms of their quite separate question of how our ordinary sensation terms can be understood, in a (...) philosophical context, to acquire meaning. Yet it is no part of his intention to demonstrate logically that ordinary sensations are not intrinsically meaningful. This is a tempting yet misleading picture, the picture also expressed through the idea of Augustine’s child who is conceptually articulateprior to learning how to talk. This picture lies behind the born Crusoe, an idea at the centre of the dichotomy between language as essentially shared and essentially shareable, a dichotomy considered here to result from a misconception of two quite separate but related aspects of Wittgenstein’s treatment offollowing a rule. The notion of a misleading picture, in both its pre-theoretical and philosophical aspects, also plays a crucial role in a treatment of Saul Kripke’s well-known “Postscript: Wittgenstein and Other Minds.”.

John Smith was among the first of the Cambridge Platonists. He was therefore in a position to influence not only his contemporaries but all those who followed after him well into the twentieth century and beyond. Well established lines of influence both to and from Whichcote, Cudworth, and More are explored first before moving on to less well-known connections to Bishop Simon Patrick and mathematician Isaac Barrow. Smith’s continued significance for eighteenth century theology is demonstrated through discussion of his inspiration (...) of the doctrines of spiritual sensation developed by Jonathan Edwards and John Wesley. Special notice is also given to Smith’s authority as an interpreter of Biblical prophecy through the eighteenth and nineteenth centuries. The chapter concludes with looks at Smith’s influence on Samuel Taylor Coleridge, Ralph Waldo Emerson, William Ralph Inge, Rufus Jones, Pierre Hadot, and others. This chapter, offers a broad, but highly selective, overview of the reception and influence of Smith’s life and work. It is intended, however, as a call for future research more than as an authoritative presentation of Smith’s legacy. For, if the Cambridge Platonists have been underappreciated until recently, none of them have been unjustly ignored as consistently as Smith. (shrink)

Can there be an objective morality without God? Derek Parfit argues that it can and offers a theory of morality that is neither theistic nor naturalistic. This book provides a critical assessment of Parfit's metaethical theory. Jakobsen identifies some problems in Parfit’s theory – problems concerning moral normativity, the ontological status of morality, and evolutionary influence on our moral beliefs – and argues that theological resources can help solve them. By showing how Parfit’s theory may (...) be improved by the help of theology, Jakobsen demonstrates the relevance of theology in philosophical and metaethical debates and argues that Christian theism offers a better explanation of morality than what Parfit’s non-naturalism does.

Abstract More than some other fields of ethics, climate ethics is related to pressing real-world problems. Climate ethicists have a responsibility to be precise about the status of the problems they discuss. The non-identity problem (NIP) plays are a prominent role in the climate ethics literature. In a widely discussed statement, Derek Parfit claimed that a risky climate policy is not harmful for (distant) future people. But this ignores the “insignificant-causal-factors rejoinder”. The Parfitian assertion is still treated as (...) serious problem to theories of climate justice in key philosophical texts, and this may mislead climate policy decision-makers. Philosophers should acknowledge that the NIP, when applied to climate change, is “just” a thought experiment and should communicate it in this way to people outside the philosophical community.

Derek Parfit’s On What Matters endorses Kantian Contractualism, the normative theory that everyone ought to follow the rules that everyone could rationally will that everyone accept. This paper explores Parfit’s argument that Kantian Contractualism converges with Rule Consequentialism. A pivotal concept in Parfit’s argument is the concept of impartiality, which he seems to equate agent-neutrality. This paper argues that equating impartiality and agent-neutrality is insufficient, since some agent-neutral considerations are silly and some are not impartial. Perhaps (...) more importantly, there is little realistic prospect of Kantian Contractualism converging with Rule Consequentialism unless the same impartial reasons drive rule selection in the two theories.

Is suffering really bad? The late Derek Parfit argued that we all have reasons to want to avoid future agony and that suffering is in itself bad both for the one who suffers and impersonally. Nietzsche denied that suffering was intrinsically bad and that its value could even be impersonal. This paper has two aims. It argues against what I call ‘Realism about the Value of Suffering’ by drawing from a broadly Nietzschean debunking of our evaluative attitudes, showing (...) that a recently influential response to the debunking challenge (the appeal to phenomenal introspection) fails. It also argues that a Nietzschean approach is well suited to support the challenge and is bolstered by the empirical literature. As strangers to ourselves, we cannot know whether suffering is really intrinsically bad for us. (shrink)

In On What Matters, Derek Parfit enters the debate between actualists and possibilists. This debate concerns mere possibilia, possible but non-actual things such as golden mountains and talking donkeys. Roughly, possibilism says that there are such things, and actualism says that there are not. Parfit not only argues for possibilism but also argues that some self-proclaimed actualists are, in fact, unwitting possibilists. -/- I argue that although Parfit’s arguments do not fully succeed, they do highlight a (...) tension within the frameworks of many actualists. Many actualists conscript abstract objects into the role of "possible worlds" to avoid quantifying over mere possibilia. But, in doing so, actualists must quantify over mere possibilia anyway. When we alleviate this tension, a Parfit-friendly form of actualism arguably remains. This form of actualism says that while everything that exists is actual, it is also true in some sense that there are mere possibilia. (shrink)

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

A foundational problem in population ethics is the “repugnant conclusion", introduced by Derek Parfit in Reasons and Persons. It holds that for any possible population of at least ten billion lives of very high positive welfare, there is some larger possible population of lives of very low positive welfare whose existence would be better, if other things are equal. I call this claim RC1. In this article, I argue that by carefully considering the nature and variety of possible (...) lives of very low positive welfare, and distinguishing RC1 from a related but stronger claim I call RC2, we can show that RC1 is more acceptable than it first appears. It has been claimed that perfectionism— that is, a special concern for the best things in life—is a reason to reject the repugnant conclusion. I argue that although perfectionism gives us a reason to reject RC2, it does not give us any reason to reject, and might in fact support, RC1. In his last two papers on the subject, Parfit develops a strategy for avoiding the repugnant conclusion that appeals in part to perfectionism. In the final part of this article, I argue that Parfit’s strategy can help us avoid RC2 but not RC1. If I am right that RC1 is more acceptable than RC2, this may not be an unwelcome result. (shrink)

The repugnant conclusion poses a conundrum in population ethics that has evaded satisfactory solution for four decades. In this article, I show that the repugnant conclusion can be avoided without sacrificing any moral intuitions. The resulting framework satisfies Parfit's requirements for `theory X'. This is achieved using non-Archimedean orders, which admit the possibility of pairs of goods for which no amount of one is better than a single unit of the other. I show that with minimal assumptions, not only (...) are such goods sensible, they are compulsory. I show that utilitarianism and expected utility theory in their canonical forms are not in general suitable in this setting, and using these tools naively can lead to ethical errors that are arbitrarily serious. Multi-dimensional lexicographic expected utility representations may be required. I use fuzzy sets to show that there needn't be a clear boundary separating goods that are not Archimedean equivalent. This may be unavoidable due to intrinsic physical limits on the ability to discriminate between different goods arising from e.g. quantum mechanics. Limited discriminatory power causes preferences to be non-transitive, which can resolve problems related to so-called `fanaticism' and `recklessness' wherein `rational' decision-makers counterintuitively prefer arbitrary long shot bets to a guaranteed lesser outcome. (shrink)

In On What Matters, Derek Parfit defends a new metaethical theory, which he calls non-realist cognitivism. It claims that normative judgments are beliefs; that some normative beliefs are true; that the normative concepts that are a part of the propositions that are the contents of normative beliefs are irreducible, unanalysable and of their own unique kind; and that neither the natural features of the reality nor any additional normative features of the reality make the relevant normative beliefs true. (...) The aim of this article is to argue that Parfit’s theory is problematic because its defenders have no resources to make sense of the nature of normative truth, which is an essential element of their view. I do this by showing how the traditional theories of truth are not available for the non-realist cognitivists. (shrink)

Derek Parfit defended Non-Realist Cognitivism. It is an open secret that this metaethical theory is often thought at best puzzling and at worst objectionably unclear. Employing truthmaker theory, I provide an account of Non-Realist Cognitivism that dispels charges of objectionable unclarity, clarifies how to assess it, and explains why, if plausible, it would be an attractive theory. I develop concerns that the theory involves cheating into an objection that ultimately reveals Non-Realist Cognitivism faces a dilemma. Whether it can (...) escape demands further attention. In bridging metaethics and the truthmaking literature, I illustrate the importance of greater meta-metaphysical reflection in metaethics. (shrink)

A number of moral philosophers have endorsed instances of the following curious argument: it would be better if a certain moral theory were true; therefore, we have reason to believe that the theory is true. In other words, the mere truth of the theory—quite apart from the results of our believing it or acting in accord with it—would make for a better world than the truth of its rivals, and this fact provides evidence of the theory’s truth. This form of (...) argument may seem to be an obvious non-starter. After all, the fact that the truth of some empirical claim, say, the claim that there is an afterlife, would be desirable does not, by itself, give us any reason to believe it. But I argue that, when it is properly understood, this form of argument—which I call the better world argument—is valid in moral philosophy. I develop and defend a version of the argument that rests on the view that the correct moral theory cannot exhibit a certain form of self-defeat—a form that, as far as I know, has not been discussed in the literature. I also identify two promising applications of this form of argument. The first is a defense of permissions to promote one’s own private aims, rather than promote the greater good, and the second, an argument against the possibility of moral dilemmas. (shrink)

Derek Parfit’s early work on the metaphysics of persons has had a vast influence on Western philosophical debates about the nature of personal identity and moral theory. Within the study of Buddhism, it also has sparked a continuous comparative discourse, which seeks to explicate Buddhist philosophical principles in light of Parfit’s conceptual framework. Examining important Parfitian-inspired studies of Buddhist philosophy, this article points out various ways in which a Parfitian lens shaped, often implicitly, contemporary understandings of the (...) anātman doctrine and its relation to Buddhist ethics. I discuss in particular three dominant elements appropriated by Parfitian-inspired scholarship: Parfit’s theoretical categories; philosophical problems raised by his reductionist theory of persons; and Parfit’s argumentative style. I argue that the three elements used in this scholarship constitute different facets of one methodological approach to cross-cultural philosophy, which relies on Western terminology and conceptual schemes to establish a conversation with non-Western philosophy. I suggest that while this methodology is fruitful in many ways, philosophy as a cosmopolitan space may benefit significantly from approaching Buddhist philosophy using its own categories and terminology.

This paper addresses a question concerning psycho­logical continuity, i.e., which features preserve the same psychological subject over time; this is not the same question as the one concerning the necessary and sufficient conditions for personal identity. Marc Slors defends an account of psychological continuity that adds two features to Derek Parfit’s Relation R, namely narrativity and embodiment. Slors’s account is a significant improvement on Parfit’s, but still lacks an explicit acknowledgment of a third feature that I call (...) relationality. Because they are usually regarded as cases of radical discontinuity, I start my discussion from the experiences of psychological disruption undergone by victims of severe violence and trauma. As it turns out, the challenges we encounter in granting continuity to the experiences of violence and trauma victims are germane to those we encounter in granting continuity to the experiences of subjects in non-traumatic contexts. What is missing in the most popular accounts of psychological continuity is an explicit acknowledgment of the links that tie our psychological lives to other subjects. A more persuasive notion of psychological continuity is not only embodied and narrative, as is Slors’s notion, but also explicitly relational. (shrink)

One of Derek Parfit’s greatest legacies was the search for Theory X, a theory of population ethics that avoided all the implausible conclusions and paradoxes that have dogged the field since its inception: the Absurd Conclusion, the Repugnant Conclusion, the Non-Identity Problem, and the Mere Addition Paradox. In recent years, it has been argued that this search is doomed to failure and no satisfactory population axiology is possible. This chapter reviews Parfit’s life’s work in the field and (...) argues that he provided all the necessary components necessary for a Theory X. It then shows how these components can be combined together and applied to the global challenges Parfit argued matter most: preventing human extinction, managing catastrophic risks, and eradicating global poverty and suffering. Finally, it identifies a number of challenges facing his theory and suggests how these may be overcome. (shrink)

John Broome claims that there is a sacrifice-free solution to climate change. He says this is a consequence of elementary economics. After explaining the economic argument in somewhat more detail than Broome, I show that the argument is unsound. A main problem with it stems from Derek Parfit's ‘nonidentity effect.’ But there is hope, since the nonidentity effect underwrites a more philosophical yet more plausible route to a sacrifice-free solution. So in the end I join Broome in asking (...) economists and policymakers to help make this a reality. (shrink)

Hybridization by introgression (“hybridization”) is a complex topic in conservation. Many conservation decision-makers are concerned about hybridization by introgression because it may threaten species persistence or local phenotypes, among other potential long-term problems. While attitudes have changed towards hybridization as a conservation threat, there are still concerns about hybridization as a problem, particularly if the hybridization was anthropogenically mediated. I propose that these concerns are overblown and that it is misguided to focus on whether hybridization is unintentionally human-mediated. I argue (...) that practitioners should still consider the effects of hybridization on conservation, but the reasons should concern the long-term environmental consequences, such as ecological function and social and cultural that hybridization has, rather than whether humans “caused” the hybrid. I propose a series of steps to think differently about these cases. (shrink)

Part of the philosophical interest of the topic of organic individuals is that it promises to shed light on a basic and perennial question of philosophical self-understanding, the question what are we? The class of organic individuals seems to be a good place to look for candidates to be the things that we are. However there are, in principle, different ways of locating ourselves within the class of organic individuals; organic individuals occur at both higher and lower mereological levels than (...) the stereotypical bounded and physiologically unified vertebrate organism. The view that we are organic individuals smaller than the physiological organism is one that has recently been endorsed by Derek Parfit. This paper attempts to resolve a dispute between Parfit’s ‘embodied part’ view and a contrary ‘animalist’ view according to which we are whole organisms. It is explained why a problem of multiple thinkers presents a serious obstacle to a straightforward resolution of this dispute. Parfit’s own strategy for dealing with this obstacle is found to be problematic. However his strategy has a certain general shape, which can be instantiated in a different, and better, specific way. I close in the final section, not with a definite resolution of the dispute, but with illustration of how progress on the question of about which organic individuals we are requires engagement with questions about the nature and function of self-awareness.

In this article, I argue that guilt and shame are not distinctive emotions. Instead, guilt is best seen as a kind of shame. I present three reasons for this view: First, guilt cannot merely arise as a consequence of how we evaluate our behaviour, since how we act implicates the whole self. Second, guilt cannot be relieved by taking responsibility, apologising and making amends unless it is a kind of shame. Third, the empirical research that seems to show that ‘shame’ (...) and ‘guilt’ are distinct can be explained by re-interpreting the data. (shrink)

In earlier work, I predicted that we would probably not be able to determine the colors of the dinosaurs. I lost this epistemic bet against science in dramatic fashion when scientists discovered that it is possible to draw inferences about dinosaur coloration based on the microstructure of fossil feathers (Vinther et al., 2008). This paper is an exercise in philosophical error analysis. I examine this episode with two questions in mind. First, does this case lend any support to epistemic optimism (...) about historical science? Second, under what conditions is it rational to make predictions about what questions scientists will or will not be able answer? In reply to the first question, I argue that the recent work on the colors of the dinosaurs matters less to the debate about the epistemology of historical science than it might seem. In reply to the second question, I argue that it is difficult to specify a policy that would rule out the failed bet without also being too conservative. (shrink)

Bernard Williams's motivational reasons-internalism fails to capture our first-order reasons judgements, while Derek Parfit's nonnaturalistic reasons-externalism cannot explain the nature or normative authority of reasons. This paper offers an intermediary view, reformulating scepticism about external reasons as the claim not that they don't exist but rather that they don't matter. The end-relational theory of normative reasons is proposed, according to which a reason for an action is a fact that explains why the action would be good relative to (...) some end, where the relevant end for any ascription of reasons is determined by the speaker's conversational context. Because these ends need not be the agent's ends, Williams is wrong to reject the existence of external reasons. But contra Parfit, a reason for action is only important for an agent if it is motivationally internal to that agent. (shrink)

Is there one univocal or generic notion of ground? Monists answer yes, while pluralists answer no. Pluralists argue that monism cannot meet plausible constraints on an adequate theory of ground. My aim in this paper is to articulate a monist theory of ground that can satisfy the pluralist constraints in a way that leaves the pluralists with no reasons not to endorse the monist picture of ground. I do this by adopting a tripartite conception of ground and then showing that (...) it has the resources to vindicate monism while satisfying the pluralist constraints on a theory of ground.

According to moral non-naturalism, the kind of genuine or robust normativity that is characteristic of moral requirements cannot be accounted for within a wholly naturalistic worldview, but requires us to posit a domain of non-natural properties and facts. The main argument for this core non-naturalist claim appeals to what David Enoch calls the 'just-too-different intuition'. According to Enoch, robust normativity cannot be natural, since it is just too different from anything natural. Derek Parfit makes essentially the same claim (...) under the heading of 'the normativity objection', and several other non-naturalists have said similar things. While some naturalists may be tempted to reject this argument as methodologically or dialectically illegitimate, we argue instead that there are important limits to what the just-too-different intuition can show, even setting all other worries aside. More specifically, we argue that the just-too-different argument will backfire on any positive, independent specification of the distinction between the natural and the non-natural. The upshot is that the just-too-different argument can show significantly less than non-naturalists have suggested. (shrink)

A book chapter (about 8,000 words, plus references) summarizing Part One of Reasons and Persons, with particular attention to the Self-interest Theory, Consequentialism, Common-Sense Morality, and how critical scrutiny of Consequentialism and Common-Sense Morality points the way toward a unified theory of morality.

Our pollution of the environment seems set to lead to widespread problems in the future, including disease, scarcity of resources, and bloody conflicts. It is natural to think that we are required to stop polluting because polluting harms the future individuals who will be faced with these problems. This natural thought faces Derek Parfit’s famous Non-Identity Problem ( 1984 , pp. 361–364). The people who live on the polluted earth would not have existed if we had not polluted. (...) Our polluting behaviour does not make these individuals worse off. It may therefore seem that we do not harm them by polluting. Parfit argues that we should replace person-affecting principles with an impersonal principle of beneficence, Principle Q ( 1984 , p. 360.). I argue that Principle Q cannot give an adequate account of our duties to refrain from polluting. I consider attempts to solve the Non-Identity Problem by denying that to harm someone an agent must make them worse off. I argue that such responses provide a partial solution to the Non-Identity Problem. They do show that we harm future individuals in a morally relevant sense by polluting. Nonetheless, this is only a partial solution. The Non-Identity Problem still suggests that our harm-based reasons not to pollute are less strong than we intuitively believe. Thus on its own an appeal to the claim that we harm future individuals is not able to give a fully satisfactory account of why we are required not to pollute. (shrink)

Subjectivism about reasons is the view that a person has a reason to perform act A if she has some motivation to do A, or would have motivation to do A in certain circumstances. In On What Matters, Derek Parfit presents a series of arguments against subjectivism about reasons. In Parfit’s view, if subjectivism were true, nothing would actually matter. Parfit contends that there are only two positions regarding reasons: objectivism and subjectivism. I will argue for (...) an inclusive position on reasons that is neither subjectivist nor objectivist.

On the view I put forward, I contend, against Parfit, that even if there were no objective reasons, it would still be the case that some things matter. (shrink)
