I had taken a course in Ethics. I read a thick textbook, heard the class discussions and came out of it saying I hadn't learned a thing I didn't know before about morals and what is right or wrong in human conduct.
Carl SandburgHistory is a living horse laughing at a wooden horse. History is a wind blowing where it listeth. History is no sure thing to bet on. History is a box of tricks with a lost key. History is a labyrinth of doors with sliding panels, a book of ciphers with the code in a cave of the Saragossa sea. History says, if it pleases, Excuse me, I beg your pardon, it will never happen again if I can help it.
Carl Sandburg
