Vague and mysterious forms of speech, and abuse of language, have so long passed for mysteries of science; and hard or misapplied words with little or no meaning have, by prescription, such a right to be mistaken for deep learning and height of speculation, that it will not be easy to persuade either those who speak or those who hear them, that they are but the covers of ignorance and hindrance of true knowledge.
John LockeAn excellent man, like precious metal, is in every way invariable; A villain, like the beams of a balance, is always varying, upwards and downwards.
John LockeOur deeds disguise us. People need endless time to try on their deeds, until each knows the proper deeds for him to do. But every day, every hour, rushes by. There is no time.
John Locke
