Bering's target article proposes that the tendency to believe in an afterlife emerged (in evolutionary history) in response to selective pressures unique to human societies. However, the empirical evidence presented fails to account for the broader social context that impinges upon researcher–participant interactions, and so fails to displace the more parsimonious explanation that it is childhood credulity that underlies the acquisition of afterlife beliefs through cultural exposure.

In this essay I take issue with Derek Parfit's reductionist account of personal identity.Parfit is concerned to respond to what he sees as flaws in the conception of the role of 'person' in self-interest theories. He attempts to show that the notion of a person as something over and above a totality of mental and physical states and events (in his words, a 'further fact'), is empty, and so, our ethical concerns must be based on something other than this. My objections centre around the claim that Parfit employs an impoverished conception of 'life'. Parfit misconceives the connection between 'I' and one's body, and, so, despite his rejection of a metaphysical conception of 'self', remains within the logic of Cartesianism. What Parfit and other reductionists call an 'impersonal' perspective, I shall call the third-person perspective: a perspective which one in general may take. Against Parfit I shall offer a more complex conception of 'self' through the concept of 'bodily perspective'. I emphasize the irreducible ambiguities of human embodiment in order to show the presuppositions and the limitations of Parfit's view. Of interest is the conception of time and the model of continuity that is appropriate to an embodied subject's life. I employ Paul Ricoeur's concept of 'human time' to argue that the reflective character of human experience demands a model of temporality and continuity that differs significantly from the one Parfit employs.

According to Part VI of Derek Parfit’s On What Matters, some things matter.1 Indeed, there are normative truths to the effect that some things matter, and it matters that there are such truths. Moreover, according to Parfit, these normative truths are cognitive and irreducible. And in addition to mattering that there are normative truths about what matters, Parfit holds that it also matters that these truths are cognitive and irreducible. Indeed this matters so much that Parfit tells us that if there were normative truths, but that these truths were non-cognitive or reducible, then he, Sidgwick, and Ross “would have wasted much of our lives” [OWM2 367]. That it would be a consequence of the thesis either of noncognitivism or of reductive realism that Parfit would have wasted his life is, of course, no evidence against either thesis; it is perfectly possible even for the most brilliant thinkers to waste their lives. Indeed, as any of the students from my introductory ethics course would be quick to point out, it is very difficult to think clearly and objectively about a question in which you take yourself have a large personal stake. My undergraduates readily agree that the steak they have is enough to complicate their thinking about moral vegetarianism; so certainly explosive expressions like ‘wasted my life’ give Parfit the kind of loaded stake in metaethical questions that should make us cautious of trusting his intuitive verdicts in metaethics. Fortunately, as I will argue in this paper, Parfit has not wasted his life, and he would not have wasted his life, even if it turned out that either noncognitivism or reductive realism turned out to be true. In arguing that Parfit has not wasted his life, independently of the answer to any metaethical question, I am, of course, arguing against Parfit’s own conception of what makes his life worthwhile. Parfit clearly believes that the worthwhileness of [much of]2 his life turns on the answer to questions in metaethics..

If I understand him correctly, Derek Parfit’s views place us, philosophically speaking, in a very small box. According to Parfit, normativity is an irreducible non-natural property that is independent of the human mind. That is to say, there are normative truths - truths about what we ought to do and to want, or about reasons for doing and wanting things. The truths in question are synthetic a priori truths, and accessible to us only by some sort of rational intuition. Parfit supposes that if we are to preserve the irreducibility of the normative, this is just about all we can say, at least until we bring in some actual intuitions to supply the story with some content.

For nearly a generation, Derek Parfit's arguments in his 1984 book Reasons and Persons have shaped debates about our moral responsibilities to future people. Struggling to accommodate Parfit's insights, philosophers and bioethicists have minimized or accentuated obligations to the future in ways that defy ordinary moral intuitions. In this issue, Robert Sparrow develops the troubling implications of the views of two leading theorists whose work favoring human genetic enhancement is influenced by Parfit. Sparrow believes they return us to the horrors of early twentieth-century eugenics. But the real problem may be a purely theoretical one: the unfortunate influence of Parfit.This is no place to review all of ..

In Essays on Derek Parfit's On What Matters, seven leading moral philosophers offer critical evaluations of the central ideas presented in a greatly anticipated new work by world-renowned moral philosopher Derek Parfit. Presents critical assessments of what promises to be one of the key moral philosophy texts of our time Features essays by a team of leading philosophers including Princeton's Michael Smith, one of the world's leading meta-ethicists Addresses Parfit's central thesis - that the main ethical theories can agree on what matters - as well as his defense of moral realism.

Several prominent philosophers, including A.J. Ayer and Derek Parfit, have offered the evidentiary requirements for believing human personality can reincarnate, and hence that Cartesian dualism is true. At least one philosopher, Robert Almeder, has argued that there are actual cases which satisfy these requirements. I argue in this paper that even if we grant the empirical data-a large concession-belief in reincarnation is still unjustified. The problem is that without a theoretical account of the alleged cases of reincarnation, the empirical evidence alone does not license giving up materialist theories of the mind.

Derek Parfit's combined-spectrum argument seems to conflict with epistemicism, a viable theory of vagueness. While Parfit argues for the indeterminacy of personhood, epistemicism denies indeterminacy. But, we argue, the linguistically based determinacy that epistemicism supports lacks the sort of normative or ontological significance that concerns Parfit. Thus, we reformulate his argument to make it consistent with epistemicism. We also dispute Roy Sorensen's suggestion that Parfit's argument relies on an assumption that fuels resistance to epistemicism, namely, that 'the magnitude of a modification must be proportional to its effect.'.
