"All wars arise from population pressure." "Morals - all correct moral rules - derive from the instinct to survive; moral behavior is survival above the individual level - as in the father dying to save his children."
"I have never been able to see how a thirty-year old moron can vote more wisely than a fifteen-year old genius...
"Man is what he is, a wild animal with the will to survive [...] Unless one accepts that, anything one says about morals, war, politics - you name it - is nonsense.
Correct morals arise from knowing what Man is - not what do-gooders and well-meaning Aunt Nellies would want him to be."
(Major Reid, Moral Philosopher 7000 AD)
