Zeno and the Tortoise explains not just who each philosopher was and what he thought, but exactly how he came to think in the way that he did. Nicholas Fearn presents philosophy as a collection of tools – from Ockham’s Razor to Hume’s Fork – each of which can be brought to bear on any number of predicaments.

Written in twenty-five short chapters, each readable during the journey to work, Zeno and the Tortoise is an ideal course in intellectual self-defence.
