Discourse on Method

René Descartes's Discourse on Method is one of the most influential works in Western philosophy—a concise, personal, and revolutionary guide to thinking clearly and systematically. In this modern English edition, the archaic language and tangled syntax of seventeenth-century translations are replaced with clean, contemporary prose, while every argument and insight remains faithful to the original. Descartes recounts his intellectual journey, from rejecting inherited certainties to establishing a method of doubt, reason, and evidence. He introduces the famous cogito ergo sum ('I think, therefore I am'), proves the existence of God and the soul, and explores the mechanics of the human body and the natural world. The result is a timeless invitation to think for yourself, question assumptions, and seek truth with confidence. Whether you are new to philosophy or returning to a classic, this edition makes Descartes's vision clear, engaging, and immediately relevant. Part of The Modern Wisdom Library.
