Charles Hartshorne

Charles Hartshorne (; June 5, 1897 – October 9, 2000) was an American philosopher who concentrated primarily on the philosophy of religion and metaphysics, but also contributed to ornithology. He developed the neoclassical idea of God and produced a modal proof of the existence of God that was a development of Anselm of Canterbury's ontological argument, which influenced Gödel's ontological proof. Hartshorne is also noted for developing Alfred North Whitehead's process philosophy into process theology.
