Creating and Redirecting Threats

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.
