Like Aquinas and other notable thirteenth-century philosophers and theologians, Bonaventure believed that it is possible to logically prove the existence of God and the immortality of the soul. In fact, unlike Aquinas, Bonaventure holds that reason can demonstrate the beginning of the world. He offers several arguments for the existence of God, including versions of Anselm of Canterbury's ontological argument and Augustine's argument from eternal truths. His main argument for the immortality of the soul appeals to humans' natural desire for perfect happiness, and is reflected in C. S. Lewis's argument from desire. Contrary to Aquinas, Bonaventure did not believe that philosophy was an autonomous discipline that could be pursued successfully independently of theology. Any philosopher is bound to fall into serious error, he believed, who lacks the light of faith.Frederick Copleston, A History of Philosophy, vol. 2 (Westminster, MD: Newman Press, 1950), p. 248.
