“The great principles of right and wrong are legible to every reader; to pursue them requires not the aid of many counselors. The whole art of government consists in the art of being honest. Only aim to do your duty, and mankind will give you credit where you fail.” –Thomas Jefferson, A Summary View of the Rights of British America, 1775
