“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.”

“Morals — all correct moral laws — derive from the instinct to survive. Moral behavior is survival behavior above the individual level.”

“The instinct to survive is human nature itself, and every aspect of our personalities derives from it. Anything that conflicts with the survival instinct acts sooner or later to eliminate the individual and thereby fails to show up in future generations. . . . A scientifically verifiable theory of morals must be rooted in the individual's instinct to survive--and nowhere else!--and must correctly describe the hierarchy of survival, note the motivations at each level, and resolve all conflicts.We have such a theory now; we can solve any moral problem, on any level. Self-interest, love of family, duty to country, responsibility toward the human race . . . .The basis of all morality is duty, a concept with the same relation to group that self-interest has to individual.”

“Under what circumstances is it moral for a group to do that which is not moral for a member of that group to do alone?”

“Correct morality can only be derived from what man is — not from what do-gooders and well-meaning aunt Nellies would like him to be.”

“In terms of morals there is no such thing as ‘state.’ Just men. Individuals. Each responsible for his own acts.”

“Some logics get nervous breakdowns. Overloaded phone system behaves like frightened child. Mike did not have upsets, acquired sense of humor instead. Low one. If he were a man, you wouldn't dare stoop over. His idea of thigh-slapper would be to dump you out of bed — or put itch powder in pressure suit.”
