Different functions require different qualities; and the “evil” virtues of the strong are as necessary in a society as the “good” virtues of the weak. Severity, violence, danger, war, are as valuable as kindliness and peace; great individuals appear only in times of danger and violence and merciless necessity. The best thing in man is strength of will, power and permanence of passion; without passion one is mere milk, incapable of deeds. Greed, envy, even hatred, are indispensable items in the process of struggle, selection and survival.
