If you think philosophy is irrelevant to your daily life, think again. You need only observe the world around you to discover how substantially the ideas of history's thinkers affect us still. You can hear it in the beliefs of your non-Christian friends; in the media, your music, your children's classrooms. You can see it in our public policies, on every bookstore shelf, in the way we understand our very existence--even in the church. The greater our familiarity with the ideas that have shaped our culture over the centuries, the greater our ability to understand--and influence--that culture for Christ. From ancient Greek thinkers like Plato and Aristotle to Christian philosophers like Augustine and Aquinas to the molders of modern thought such as Kant and Nietszche, R. C. Sproul traces the contours of Western philosophy throughout history and demonstrates the massive consequences these ideas have had on world events, theology, the arts, and culture--as well as in our everyday lives.
