Wrongs are often forgiven, but contempt never is. Our pride remembers it forever. - Philip Dormer Stanhope

Take warning then by them: choose your pleasures for yourself, and do not let them be imposed upon you. Follow nature and not fashion: weigh the present enjoyment of your pleasures against the necessary consequences of them, and then let your own common sense determine your choice.

Ridicule is the best test of truth.

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.
