If you’re going to be businessmen, don’t confuse the vocation with larceny. - Robert A. Heinlein

Man has no moral instinct. He is not born with moral sense. You were not born with it, I was not - and a puppy has none. We acquire moral sense, when we do, through training, experience, and hard sweat of the mind.

It is an emotional impossibility for any man to believe in his own death.

My wife Ticky is an anarchist-individualist ... When she was in the Navy during the early 'forties she showed up one morning in proper uniform but with her red hair held down by a simple navy-blue band — a hair ribbon. It was neat (Ticky is always neat) and it suited the rest of her outfit esthetically, but it was undeniably a hair ribbon and her division officer had fits. "If you can show me," Ticky answered with simple dignity, "where it says one word in the Navy Uniform Regulations on the subject of hair ribbons, I'll take it off. Otherwise not."
See what I mean? She doesn't have the right attitude.
