Ten Philosophies That Shook the World: An Economical Introduction to Philosophy allows some of the greatest philosophers, ancient and modern, to speak for themselves and directly to readers through their own writings.

Based on John Rawls's thesis that an appreciation of a philosopher requires that "the text must be respected," these passages are largely unedited, giving readers deeper exposure to the ideas and perspectives of such canonical figures as Plato, Aristotle, and Descartes. Introductory passages and prefaces written by the author enhances understanding of the original intent of each philosopher.
