In the third volume of On What Matters, Derek Parfit argued that the distinction between imposing a newly created threat on someone and making what threatens some people instead threaten someone else has no genuine moral significance. This article's central thesis is that although there is much to learn from Parfit's arguments, they are ultimately unsuccessful at establishing that the redirected versus newly created threats distinction is morally irrelevant. In particular, I show that my Causal Sequences Principle specifies this distinction (...) in such a way that it is immune to Parfit's objections against the Redirection Principle. It follows that any moral theory that can provide a sound rationale for the Causal Sequences Principle can solve the trolley problem. (shrink)

In this paper, I engage with the original criticism of utilitarianism that Philippa Foot offers in her work on moral philosophy. I show that her discussion of this normative ethical theory was one of the reasons that the British philosopher again took up the notion of practical rationality in the last part of her work, especially in her discussion of utilitarianism and the obligation of promises in her 2001 book,Natural Goodness.
