It is not a virtue, but a deceptive copy and imitation of virtue, when we are led to the performance of duty by pleasure as its recompense.
Marcus Tullius CiceroSix mistakes mankind keeps making century after century: Believing that personal gain is made by crushing others; Worrying about things that cannot be changed or corrected; Insisting that a thing is impossible because we cannot accomplish it; Refusing to set aside trivial preferences; Neglecting development and refinement of the mind; Attempting to compel others to believe and live as we do.
