Alvin Plantinga

American philosopher

Quick Summary

Alvin Plantinga is an American philosopher known for his work in philosophy of religion and epistemology. He is particularly recognized for his contributions to the problem of evil and his defense of theistic arguments.

Plantinga is associated with a modern formulation of the ontological argument, which attempts to prove God's existence from the very concept of God. He argued that a being with "necessary existence" must exist, as such a being cannot coherently be thought not to exist. This approach seeks to establish God's existence as an ultimate fact, independent of anything else. His work engages with complex philosophical debates about God's attributes, such as omnipotence and goodness, and the existence of evil in the world.123
