1921 – 2009
William P. Alston (1921–2009) was an American philosopher of language and religion, best known for his work on epistemic justification and religious epistemology. He developed the influential theory of 'doxastic practice' to argue that perception of God can be epistemically on par with ordinary sense perception. His contributions span philosophy of language, theory of knowledge, and the rationality of religious belief.
