In all things, therefore, where we have clear evidence from our ideas, and those principles of knowledge I have above mentioned, reason is the proper judge; and revelation, though it may, in consenting with it, confirm its dictates, yet cannot in such cases invalidate its decrees: nor can we be obliged, where we have the clear and evident sentience of reason, to quit it for the contrary opinion, under a pretence that it is matter of faith: which can have no authority against the plain and clear dictates of reason.
John LockeAll the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerors (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudable business of mankind, and the most heroic of virtues.
John Locke
