About this course

In these three philosophy courses, Dr. R.C. Sproul traces the contours of Western philosophy throughout history and shows how our culture evolved to what it is today.

From ancient Greek thinkers like Socrates, Plato, and Aristotle to Christian philosophers such as Augustine, Anselm and Aquinas to the shapers of modern thought such as Hume, Kant and Nietzsche, R.C. demonstrates the consequences of each of these and other important thinkers’ ideas on world events, theology, the fine arts and culture, as well as our everyday lives.

Listen, and you will hear echoes of their ideas in your daily conversations — especially as you witness to unbelievers.

An optional book Consequences of Ideas can be purchased from the Ligonier Store here to enhance the learning experience.

This course has been approved by the Association of Christian Schools International for one Continuing Education Unit.
