John Locke

Born 29 Aug 1632; died 28 Oct 1704 at age 72. English physician who was the most important philosopher during the Age of Reason. He spent over 20 years developing the ideas he published in most significant work, Essay Concerning Human Understanding (1690) which analysed the nature of human reason, and promoted experimentation as the basis of knowledge. He established primary qualities, (ex. solidity, extension, number) as distinct from secondary qualities identified by the sense organs (ex. colour, sound). Thus the world is otherwise silent and without colour. Locke recognised that science is made possible when the primary world mechanically affects the sense organs, thereby creating ideas that faithfully represent reality. He was an acquaintance of Robert Boyle.«
