Personal time, as opposed to external time, has a certain role to play in the correct account of death and immortality. But saying exactly what that role is, and what role remains for external time, is not straightforward. I formulate and defend accounts of death and immortality that specify these roles precisely.

There are possible worlds in which time is circular and finite in duration, forming a loop of, say, 12,000 years. There are also possible worlds in which time is linear and infinite in both directions and in which history is repetitive, consisting of infinitely many 12,000-year epochs, each two of which are exactly alike with respect to all intrinsic, purely qualitative properties. Could one ever have empirical evidence that one inhabits a world of the first kind rather than a world (...) of the second kind? We argue for the affirmative answer, contra Quine, Newton-Smith, and Bergström. Our argument for that conclusion differs from an argument for the same conclusion due to Weir. Weir’s argument is probabilistic and explicitly requires having evidence against determinism. Our argument is a direct appeal to the simplicity of laws, and it involves no probabilistic component. It is modeled on Shoemaker’s argument that one could have evidence of time without change. (shrink)

On what grounds could life be made worth living given its abundant suffering? Friedrich Nietzsche was one among many who attempted to answer this question. This book attempts to disentangle Nietzsche's various critiques of pessimism, elucidating how familiar Nietzschean themes ought to be assessed against this philosophical backdrop.

Without taking a position on the overall justification of anti-doping regulations, I analyse the possible justification of Therapeutic Use Exemptions from such rules. TUEs are a creative way to prevent the unfair exclusion of athletes with a chronic condition, and they have the potential to be the least bad option. But they cannot be competitively neutral. Their justification must rest, instead, on the relevance of intentions to permissibility. I illustrate this by means of a set of thought experiments in which (...) only an athlete’s intentions vary. I argue that the Doctrine of Double Effect sheds some light on TUEs and illustrate this by applying different readings of the DDE to the thought experiment. This underpins a justification of anti-doping exemptions very different from the approach adopted by the World Anti-Doping Agency. I argue for three changes to bring TUEs in line with this understanding: rewriting of the regulations, transparency, and a greater role for athletes in determining what exemptions are allowed, and when.
