Welcome to PHIL 313
– Fall 2025 –

Killing & Letting Die

We take a dim view of someone who would kill a child for a few thousand dollars, but barely notice that we let a child die with every few thousand dollars we spend on ourselves rather than donating to help combat malaria (GiveWell.org). Like the contract killer, we knowingly (and repeatedly) take the course of action that leaves us a few thousand better off at the cost of a child’s life. This class will join the debate between those defending the comforting, commonsense view that killing is generally much harder to justify than letting die, and those arguing that this is a terrible moral mistake. By taking this class, you will discover a range of arguments in ethical theory concerning the distinction between killing & letting die and the application of that distinction to cases both real (euthanasia, duties to aid) and imagined (the famous trolley problem and any number of hypothetical drowning children). You will develop your own ability to contribute to the conversation with clear and careful philosophical analysis and argumentation.
