It is a wise thing to be polite; consequently, it is a stupid thing to be rude. To make enemies by unnecessary and willful incivility, is just as insane a proceeding as to set your house on fire. For politeness is like a counter--an avowedly false coin, with which it is foolish to be stingy.
Arthur SchopenhauerBecause people have no thoughts to deal in, they deal cards, and try and win one another's money. Idiots!
Arthur SchopenhauerIf we suspect that a man is lying, we should pretend to believe him; for then he becomes bold and assured, lies more vigorously, and is unmasked.
