Covering the biggest names, including Socrates, Seneca, St Augustine, Descartes, Marx and Nietzsche, I Think Therefore I Am provides a handle for all the main -isms and -ologies of western philosophy.

Philosophers certainly like to make life sound awfully complicated - whether they're wondering if a falling tree still makes a sound if there's nobody around to hear it (Berkeley) or declaring that everything in the universe is in a state of flux (Heraclitus).

But is philosophy really so complicated? And is it really as irrelevant as it sometimes seems? I Think, Therefore I Am is the ideal way to take the fear out of philosophy.
