in its vast scope, this book presents the continuum of Western philosophy. Ranging from ancient Greece to nineteenth-century America, it traces the history of our civilization through the seminal works of its most influential thinkers. Each philosopher in this volume made intellectual history; each created a revolution in ideas; each reaffirmed man's view of himself as a sentient being capable of creating order out of the baffling contradictions of existence. And the most powerful reflections and speculations of each are represented here.
