“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.”

“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?”

“There is no worse tyranny than to force a man to pay for what he does not want merely because you think it would be good for him.”

“History does not record anywhere at any time a religion that has any rational basis. Religion is a crutch for people not strong enough to stand up to the unknown without help. But, like dandruff, most people do have a religion and spend time and money on it and seem to derive considerable pleasure from fiddling with it.”

“- I'm so busy doing what I must do that I don't have time for what I ought to do... and I never get a chance to do what I want to do!- Son, that's universal. The way to keep that recipe from killing you is occasionally to do what you want to do anyhow.”
