Irish bishop who denied the reality of matter, holding that to be is to be perceived: the founder of subjective idealism

An Anglo-Irish philosopher who studied and taught at Trinity College Dublin and from 1734 was Bishop of Cloyne in the Church of Ireland. In the Principles of Human Knowledge (1710) and the Three Dialogues between Hylas and Philonous (1713) he argued for immaterialism: there is no material substance, and things are ideas perceived by minds, a view summed up as "to be is to be perceived". The position later came to be called subjective idealism and influenced Hume and Kant. His critique of Newton's absolute space anticipated Mach, and in Materialism and Empirio-criticism Lenin traced Machism back to Berkeley.
