In seeking wisdom thou art wise; in imagining that thou hast attained it - thou art a fool.
Lord ChesterfieldNo man can possibly improve in any company for which he has not respect enough to be under some degree of restraint.
Lord ChesterfieldA seeming ignorance is very often a most necessary part of worldly knowledge. It is, for instance, commonly advisable to seem ignorant of what people offer to tell you; and when they say, Have not you heard of such a thing? to answer No, and to let them go on, though you know it already.
