"The philosophy of the Enlightenment insisted on man's essential autonomy: man is responsible to himself, to his own rational interests, to his self-development, and, by an inescapable extension, to the welfare of his fellow man. For the philosophes, man was not a sinner, at least not by nature; human nature -- and this argument was subversive, in fact revolutionary, in their day -- is by origin good, or at least neutral. Despite the undeniable power of man's antisocial passions, therefore, the individual may hope for improvement through his own efforts -- through education, participation in politics, activity in behalf of reform, but not through prayer." [Peter Gay]"Conservative, n. A statesman who is enamored of existing evils, as distinguished from the Liberal, who wishes to replace them with others." [Ambrose Bierce, "Devil's Dictionary," 1911]The noun meaning "member of the Liberal party of Great Britain" is from 1820.
