Whoever desires to found a state and give it laws must start with assuming that all men are bad and ever ready to display their vicious nature, whenever they may find occasion for it.

Niccolò Machiavelli (1469-1527) Italian politician, philosopher, political scientist

The Discourses on Livy, Book 1, Introduction (1517) [tr. Detmold (1882)]

Alt. trans.: "It is necessary for him who lays out a state and arranges laws for it to presuppose that all men are evil and that they are always going to act according to the wickedness of their spirits whenever they have free scope." [Discourse upon the First Ten Books of Livy, Book 1, ch. 3 (1513-18) [tr. Gilbert]]
