Among all the arguments for the existence of God there may be none more personal and intimate than C. S. Lewis's Argument from Desire. This book attempts to explain what the Argument from Desire is and why we believe that the argument is an inductively strong one. In the spirit of C. S. Lewis, Augustine, and Pascal, this book invites both the head and the heart of the reader to consider the case for God's existence. While many arguments look out to the external world for evidence of God's existence, this book calls the reader to look inward to the human heart. While learning from classical thinkers (particularly C. S. Lewis) the Argument from Desire will bring both intuition and experience together to demonstrate the truth of divine presence in the world. The reader will walk away with either a newfound faith or a reinforced conviction that has a strong intellectual and experiential dimension.
