Anselm's Proslogion

Anselm's "Proslogion" is a philosophical work that argues for the existence of God using reason rather than faith. Anselm introduces the concept of God as "that than which nothing greater can be conceived." He argues that if God exists only in the mind, a greater being could be imagined to exist in reality, which would contradict the definition of God. Therefore, God must exist in reality. Anselm’s argument is a foundational piece in medieval philosophy and has sparked extensive debate on the nature of God and existence.
