According to philosophical orthodoxy, there are informative criteria of identity over time. Anti-criterialism rejects this orthodoxy and claims that there are no such criteria. This paper examines anti-criterialism in the light of recent attacks on the thesis by Matt Duncan, Sydney Shoemaker and Dean Zimmerman. It is argued that those attacks are not successful. Along the way, a novel strategy to defend anti-criterialism against the critics’ most challenging objection is developed. Under-appreciated difficulties for criterialism are also raised which, I claim, (...) there is no obvious way to solve. It is concluded that anti-criterialism may be a much stronger rival to criterialism than is often supposed. (shrink)

Among your closest associates is a certain human animal – a living, breathing, organism. You see it when you look in the mirror. When it is sick, you don't feel too well. Where it goes, you go. And, one thinks, where you go, it must follow. Indeed, you can make it move through sheer force of will. You bear, in short, an important and intimate relation to this, your animal. So too rest of us with our animals. Animalism says that (...) this relation is nothing short of identity. According to animalists, we do not only coincide with or constitute or inhabit or otherwise hang out with these close associates, our animals: we are them. In this article, I offer an opinionated take on what animalism might be and situate it against contemporary rivals. Then, I outline a simple case for animalism. Finally, I sketch non-standard routes for animalists to take in light of standard challenges. My goal in all of this is to open up some new avenues of animalist thinking. (shrink)

Those who endorse the Psychological Continuity Approach (PCA) to analyzing personal identity need to impose a non-branching constraint to get the intuitively correct result that in the case of fission, one person becomes two. With the help of Brueckner's (2005) discussion, it is shown here that the sort of non-branching clause that allows proponents of PCA to provide sufficient conditions for being the same person actually runs contrary to the very spirit of their theory. The problem is first presented in (...) connection with perdurantist versions of PCA. The difficulty is then shown to apply to endurantist versions as well. (shrink)

In this paper I outline and defend a new approach to personal-identity—personal-identity non-cognitivism—and argue that it has several advantages over its cognitivist rivals. On this view utterances of personal-identity sentences express a non-cognitive attitude towards relevant person-stages. The resulting view offers a pleasingly nuanced picture of what we are doing when we utter such sentences.

Derek Parfit’s thesis that identity doesn’t matter in survival has been extensively discussed except for its metaphysical robustness. How can we justify the abandonment of identity in the way Parfit suggests? My argument is the following. Those who want to endorse the thesis that identity doesn’t matter (and, therefore, abandon identity across time) should adopt exdurantism, i.e. a metaphysics according to which the world is composed by temporal parts each existing at a time and according to which there is nothing (...) as a numerically same entity which exists at different times. I show that the metaphysics behind Parfit’s theory is neither compatible with endurantism, according to which object persists by being wholly present at different times, nor with perdurantism, according to which entities are aggregates of temporal and spatial parts.

This paper considers the question whether a psychological approach to personal identity can be formulated within an endurantist, as opposed to four-dimensionalist, framework. Trenton Merricks has argued that this cannot be done. I argue to the contrary: a perfectly coherent endurantist version of the psychological approach can indeed be formulated.

Moral responsibility seems to presuppose personal identity. However, there are problems with this view, raised by Derek Parfit’s arguments for the view that personal identity isn’t what matters for our practical concerns. While Parfit discusses moral responsibility only in passing, the problems that arise for the connection between moral responsibility and personal identity have recently been sharpened by David Shoemaker. This paper defends the claim that moral responsibility presupposes personal identity against these problems. It argues, first, that only reductionist views (...) about personal identity have problems with the connection between responsibility and identity, which suggests that personal identity is a non-reductionist concept. Second, it argues that while non-reductionism is problematic, there is a novel view—non-representationalism about personal identity, according to which we account for personal identity in terms of a distinctive non-representational function—that is equally well-positioned to rescue the connection as non-reductionism, without suffering from non-reductionism’s problems.

Abstract: Those who endorse the Psychological Continuity Approach (PCA) to analyzing personal identity need to impose a non-branching constraint to get the intuitively correct result that in the case of fission, one person becomes two.

What is the relation between a clay statue andthe lump of clay from which it is made? According to the defender of the standardaccount, the statue and the lump are distinct,enduring objects that share the same spatiallocation whenever they both exist. Suchobjects also seem to share the samemicrophysical structure whenever they bothexist. This leads to the standard objection tothe standard account: if the statue and thelump of clay have the same microphysicalstructure whenever they both exist, how canthey differ in their (...) de re temporalproperties, de re modal properties and soon? In this paper I develop amereological answer to this question – thestatue and the lump differ with respect totheir parts and this explains theirdifference with respect to de re temporalproperties, de re modal properties andthe like.

The so-called 'Extreme Claim' asserts that reductionism about personal identity leaves each of us with no reason to be specially concerned about his or her own future. Both advocates and opponents of the Extreme Claim, whether of a reductionist or non-reductionist stripe, accept that similar problems do not arise for non-reductionism. In this paper I challenge this widely held assumption.

It is a commonplace that things persist, though thinkers disagree over what persistence consist in. Views about time are closely related to views about persistence, though some have questioned the compatibility of certain combinations, such as Jonathan Tallant’s recent argument that presentism is incompatible with all views of persistence, including endurantism. We believe that such arguments can be avoided with neutral definitions of the terms. However, a nearly exhaustive investigation of contemporary literature revealed that, except for two that we could (...) find, all definitions of “persist,” “endure,” and derivatives are incompatible with presentism! And, the exceptions fail to capture endurantist intuitions about endurance. But we believe that present-friendly and intuitive definitions of these concepts can be given. In this paper we offer such definitions. We go on to apply our definitions to two sample cases, showing that if our neutral definitions are used, the arguments in the cases fail. (shrink)

Trenton Merricks has argued that given endurantism personal identity is unanalysable in terms of psychological continuity, while Anthony Brueckner has argued against this claim. This article shows that neither philosopher has made a compelling case and also shows what it would take to settle the issue either way. It is then argued that whether personal identity is analysable or not may not be of crucial importance to those wanting to defend a psychological continuity approach to personal identity.
