The view that an account of personal identity can be provided in terms of psychological continuity has come under fire from an interesting new angle in recent years. Critics from a variety of rival positions have argued that it cannot adequately explain what makes psychological states co-personal (i.e. the states of a single person). The suggestion is that there will inevitably be examples of states that it wrongly ascribes using only the causal connections available to it. In this paper, I describe three distinct attacks on the psychological continuity theory along these lines. While I acknowledge that a number of interesting issues arise, I argue that the theory can withstand all three attacks.

The aim of this paper is to re-evaluate the manner in which the Ticking Bomb Scenario (TBS), a thought experiment in philosophical enquiry, has been used in the discussion of the justifiability or otherwise of forward-looking interrogational torture (FLIT). The paper argues that criticisms commonly raised against the thought experiment are often inappropriate or irrelevant. A great many criticisms misunderstand the way in which thought experiments in general, and the TBS in particular, are supposed to work in philosophical (and for that matter scientific) inquiry. The paper is not about the acceptability or otherwise of FLIT per se but rather an attempt to show that thought experiments such as the TBS are useful analytic tools and ought not to be rejected due to their inappropriate use by those engaged in the justifiability or otherwise of FLIT. By rescuing the TBS from its erroneous use the paper seeks to show its proper worth as part of an argumentative device in uncovering conflicting moral intuitions in our search for ethical truths.

Marya Schechtman has raised a series of worries for the Psychological Continuity Theory of personal identity (PCT) stemming out of what Derek Parfit called the ‘Extreme Claim’. This is roughly the claim that theories like it are unable to explain the importance we attach to personal identity. In her recent Staying Alive (2014), she presents further arguments related to this and sets out a new narrative theory, the Person Life View (PLV), which she sees as solving the problems as well as bringing other advantages over the PCT. I look over some of her earlier arguments and responses to them as a way in to the new issues and theory. I argue that the problems for the PCT and advantages that the PLV brings are all merely apparent, and present no reason for giving up the former for the latter.
