This is the ´philosophy and. .´ book that really needed to be written - because it is about The Hitchhiker´s Guide to the Galaxy. For (to paraphrase the great man himself) Hitchhiker´s is not above a little philosophy in the same way that the sea is not above the sky. Moreover: this edited collection combines accessibility - and some humour - with rigour. It contains an introduction, nine chapters, a glossary, and multiple indexes. Topics covered include the meaning of life (and ´42´), vegetarianism, the ethics of entertainment, artificial intelligence, multiple worlds, God, and philosophical method.
