Common sense is the best sense I know of - Philip Dormer Stanhope

errors and mistakes, however gross, in matters of opinion, if they are sincere, are to be pitied, but not punished nor laughed at. The blindness of the understanding is as much to be pitied as the blindness of the eye; and there is neither jest nor guilt in a man's losing his way in either case. Charity bids us set him right if we can, by arguments and persuasions; but charity, at the same time, forbids, either to punish or ridicule his misfortune.

Conceal your learning from the company.

Never display your learning, but on particular occasions. Reserve it for learned men, and let even these rather extort it from you, than appear forward to display it. Hence you will be deemed modest, and reputed to possess more knowledge than you really have. Never seem wiser or more learned than your company. The man who affects to display his learning, will be frequently questioned; and if found superficial, will be ridiculed and despised; if otherwise, he will be deemed a pedant. Nothing can lessen real merit (which will always shew itself) in the opinion of the world, but an ostentatious display by its possessor.

Courts are, unquestionably, the seats of politeness and good breeding; were they not so, they would be the seats of slaughter and desolation. Those who now smile upon and embrace, would affront and stab, each other, if manners did not interpose.
