There is a saying that goes don't learn the tricks of the trade, learn the trade, but philosophy is all tricks. This work explains not just who each philosopher was and what he thought, but exactly how he came to think in the way that he did. In this title philosophy is presented as a collection of tools - from Ockham's razor to Hume's fork - each of which can be brought to bear on a variety of predicaments. Written in short chapters, each readable during the journey to work, Zeno and the Tortoise provides a course in intellectual self-defence. It aims to arm the reader with the perfect cognitive weapons to tackle any situation - from meeting a stranger in a dark alley to arranging a first date.
