In this paper I will be discussing the Existence of God. I will compare the philosophers Benedict de Spinoza (1632-1677) and Thomas Aquinas (1225-1274) in order to illustrate that God exists as the sole creator of the universe. I will begin by explaining each philosopher’s idea on God, and how good and evil exists within each theory. In the final section of my paper I will compare the two philosopher’s concepts in order to establish that Aquinas’ notion of God has superior proof than that of Spinoza’s. In doing so, I will demonstrate that God exists as a Creating, Loving, and Personal God that has and will continue to exist infinitely outside of space and time.
