Bernard Williams (1973) famously argued that if given the choice to relinquish our mortality we should refuse. We should not choose to always live. His piece provoked an entire literature on the desirability of immortality. Intending to contradict Williams, Thomas Nagel claimed that if given the choice between living for a week and dying in five minutes he would always choose to live. I argue that (1) Nagel’s iterating scenario is closer to the original Makropulos case (Čapek’s) that inspired Williams’s piece; (2) iterating versions of the choice given in the Makropulos case might well be less desirable than a one-time choice; and (3) Nagel’s mathematical induction premise is implausible. I discuss some useful implications of (1)-(3) for the broader discussion of Williams’s arguments and, more generally, for our understanding of the value of mortality and the possibility of mutually consistent but necessarily incompatible wants in ordinary human psychology.

It is well known that Aristotle tries to make room for self-motion – an idea he inherits to some extent from Plato – within his other commitments to causal determinism while at the same time modifying the idea. However, one argument in Physics VII 1 seems to pose a problem for the bare possibility of self-motion; in it he seems to argue that everything that moves must be moved by something else. The text in which this argument appears is itself vexed on a number of fronts, because it is not clear how Physics VII fits with the rest of the Physics, and also because there are two distinct manuscript traditions for Physics VII. So the argument in Physics VII 1 has not been adequately taken into account in discussions of self-motion. I argue for a new and charitable reading of Aristotle’s Physics VII 1 α241b35-242a49 / β241b25-242a15. I show that the argument is compatible with Aristotle’s endorsements of self-motion; I defend the argument’s most controversial premise; and I argue that my reading has some useful implications for understanding Aristotelian self-motion.

Early on in his Nicomachean Ethics, Aristotle argues that there must be a single end or good desired for its own sake, for the sake of which all of our other ends are desired. The argument includes the following conditional: “If we chose everything for the sake of something else so that the process went on forever, then our desire would be empty and futile.” This paper addresses that conditional. First, I explain why the conditional appears to be false. Second, I resolve some ambiguity in it. Third, I argue that the conditional enjoys a plausible and charitable reading when understood as a claim about ordinary human lives and psychology, and when read in the context of Aristotle’s conception of ethics.

In his Metaphysics Γ.4, Aristotle defends the principle of non-contradiction (PNC). The PNC says that all contradictions are false. So if some contradictions are true, then PNC is false. Even if PNC’s contrary is false, PNC’s contradictory might still be true. But it’s been noted in the literature for over a century that Aristotle seems to be exclusively interested in attacking PNC’s contrary (‘All contradictions are true’) rather than PNC’s contradictory (‘Some contradictions are true’). So his defense of PNC seems to fail. This would be a surprising error from the inventor of formal logic. It is especially puzzling because we have plenty of evidence showing that Aristotle is keenly aware of the distinction between contraries and contradictories, and because Aristotle distinguishes between PNC’s contradictory and PNC’s contrary in Γ.4. I defend Aristotle against these charges: (1) I explain that one important reason for Aristotle’s focus on PNC’s contrary is that he took it to be deeply connected to views held by thinkers such as Anaxagoras, Cratylus, Democritus, Empedocles, Heraclitus, Parmenides, Protagoras, and Xenophanes; (2) Aristotle’s defense of PNC must be a particular kind of indirect defense rather than a direct demonstration; (3) I argue that if Aristotle’s defense of PNC is read as centering around his argument for what counts as a thing that is determinate, Aristotle demonstrates the reliance of coherent communication on non-contradiction. Read this way, he gives a fairly compelling case to reject not just PNC’s contrary but also PNC’s contradictory.

Harry Frankfurt Journal of Philosophy, 66, 829–39 famously attacked what he called the principle of alternate possibilities. PAP states that being able to do otherwise is necessary for moral responsibility. He gave counterexamples to PAP known since then as “Frankfurt cases.” This paper sidesteps the enormous literature on Frankfurt cases while preserving some of our salient pretheoretical intuitions about the relation between alternate possibilities and moral responsibility. In particular, I introduce, explain, and defend a principle that has so far been overlooked, namely, “the principle of doxastic moral asymmetry” : a rational agent, S, is morally responsible for an action that S performed, E, only if, when S did E, S justifiably believed either that E was closer to S’s most praiseworthy alternate possibility than it was to S’s most blameworthy alternate possibility, or that E was closer to S’s most blameworthy alternate possibility than it was to S’s most praiseworthy alternate possibility.

Anthropocentric biocentrism says that human beings ought to promote the survival of our own species above the survival of other species. But those who attack AB sometimes take it to say something much stronger: we ought to promote our species’ various desires, interests, and goals. I call the latter view AB+. I argue that AB and anti-AB+ are not only mutually compatible but in some respects mutually complementary, such that there are good prospects for combining them into a hybrid-view. After all, we know that the survival of our species is deeply connected to the well being of the environment.

Harry Frankfurt (1969) famously gave cases in which an agent lacks alternate possibilities and yet seems morally responsible. Such cases purportedly falsify the Principle of Alternate Possibilities, which states that the ability to do otherwise is necessary for moral responsibility. There is an enormous body of literature debating whether or not Frankfurt cases and their variants do in fact falsify PAP. In order to sidestep Frankfurt cases altogether, Garry Young (2016) argues for a different version of PAP, namely, PAP, on which alternate possibilities are sufficient rather than necessary for moral responsibility. Young also argues for another sufficient but not necessary condition, the ‘Twin World Condition’. Only one of PAP and TWC needs to be satisfied for moral responsibility. I argue here that Young’s proposal as it stands generates too much moral responsibility. So I present versions of Young’s conditions that avoid this problem. I also argue that even with those revisions, Young’s proposal does not limit moral responsibility as effectively as PAP does.
