A Murder Puzzle - Getting Started

In common with a number of other activities on this site, Murder Play is based on the work of our favourite philosopher, Judith Jarvis Thomson. Probably you'll be pleased to hear that this time it doesn't involve trolleys. However, it does involve a surgeon, and a murder, so that's exciting; and it won't take very long, so click the button below to get started.

Really Deep Thought

There are two kinds of truths: those of reasoning and those of fact. The truths of reasoning are necessary and their opposite is impossible; the truths of fact are contigent and their opposites are possible.
--Gottfried Leibnitz.
