FROM THE PUBLISHER Philosophy is about the big questions - where are we from, why are we here, and what's going to happen afterward? - and the various answers that people have come up with. This book will guide you along the route that leads from the Nichamachean Ethics of Aristotle via the Summa Theologica of Aquinas to the discourse on Method of Descartes and onward to Wittgenstein's Tractatus Logico-philosophicus, with breaks for refreshment at the cooling springs of Hume's Treatise on Human Nature and the stirring heat of Nietzsche's Also sprach Zarathustra. Get a Grip on Philosophy includes clear explanations of all the different branches of philosophy, traces the development of human thinking on the meaning of life, and gives the key ideas of all the significant philosophers in a digestible fashion. If you think Heidegger is a piece of agricultural machinery, this is the book for you.
