Archival Overview
Irish philosopher and Anglican bishop who formulated subjective idealism (immaterialism), asserting with the maxim 'esse est percipi' (to be is to be perceived) that material objects exist only as perceptions in minds.
Biographical Record
Educated at Trinity College Dublin, George Berkeley (1685–1753) published 'A Treatise Concerning the Principles of Human Knowledge' in 1710 at age twenty-five. He attacked John Locke's distinction between primary and secondary qualities, demonstrating that mind-independent material substance is a philosophical impossibility.
For Berkeley, physical reality consists entirely of ideas perceived by human minds and sustained continuously by the omnipresent perception of God. In 'The Analyst' (1734), he published a brilliant mathematical critique of Newton's calculus, mocking infinitesimals as 'ghosts of departed quantities.'
