In 1734, he was appointed Bishop of Cloyne in Ireland. He is best known for his doctrine of immaterialism, the idea that reality has no material existence outside of the mind. Berkeley's major works include An Essay towards a New Theory of Vision, A Treatise Concerning the Principles of Human Knowledge, and Three Dialogues between Hylas and Philonous.
