Men in great place are thrice servants; servants of the sovereign state, servants of fame, and servants of business; so as they have no freedom, neither in their persons, nor in their actions, nor in their times. It is a strange desire to seek power and to lose liberty; or to seek power over others, and to lose power over a man's self.
John LockeIt is hard to know what other way men can come to truth, to lay hold of it, if they do not dig and search for it as for gold and hid treasure; but he that does so, must have much earth and rubbish, before he gets the pure metal; sand, and pebbles, and dross usually lie blended with it, but the gold is nevertheless gold, and will enrich the man that employs his pains to seek and separate it.
John LockeAll men are liable to error; and most men are, in many points, by passion or interest, under temptation to it.
