The book is comprised of 100 brief yet stimulating thought experiments that introduce various aspects of philosophy to the reader. Baggini bases the experiments on famous philosophical ideas from popular culture and philosophy (the title of the book is an allusion to a meal in Douglass Adams' Hitchhiker series that could talk and requested to be eaten), and poses the questions to engender thinking about the topic rather than to tell anyone what the proper answer might be (although Baggini suggests ways to approach the problem in the comment section that follows each experiment.)
This book would make an excellent introduction to philosophical thought. If interested, here is a review from the Guardian.Their description:
Some of the most famous arguments and problems in philosophy are based around thought experiments. Bizarre stories about brain-transplants, runaway trams, concrete sheep and invisible gardeners abound. In The Pig That Wants to Be Eaten, Julian Baggini has collected together 100 entertaining examples. The format is essentially the same as that first successfully introduced by Martin Cohen's 101 Philosophy Problems. Each thought experiment is set up in one or two paragraphs, followed by a few hundred words of thought-provoking discussion. Baggini offers us a tempting smorgasbord of some of the most baffling, weird and occasionally downright creepy scenarios ever envisaged.
