A Treatise Concerning the Principles of Human Knowledge

1710 · 18th Century · Philosophy

George Berkeley's Treatise Concerning the Principles of Human Knowledge, published in Dublin in 1710 when its author was a twenty-five-year-old fellow of Trinity College, argues that the material world, understood as an unthinking substance existing outside every mind, is a philosophers' invention. What exists are minds and the ideas they perceive; for sensible things, to be is to be perceived.
