John Locke : (5) " The reason why men enter into society is the preservation of their property. " - John Locke " An 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 Locke " Things of this world are in so constant a flux, that nothing remains long in the same state. " - John Locke " Our 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 " The improvement of understanding is for two ends: first, our own increase of knowledge; secondly, to enable us to deliver that knowledge to others. " - John Locke
