Liberty in thought and action is the only condition of life, growth and well-being: Where it does not exist, the man, the race, and the nation must go down.
Still, it is the primary right of men to die and kill for the land they live in, and to punish with exceptional severity all members of their own race who have warmed their hands at the invaders' hearth.
I have damaged my intellect trying to imagine why a man should want to invent a repeating clock, and how another man could be found to lust after it and buy it. The man who can guess these riddles is far on the way to guess why the human race was invented - which is another riddle which tires me.
To reduce man to the duties of his own city, and to disengage him from duties to the members of other cities, is to break the universal society of the human race.
In other words, character is far more important than intellect to the race as to the individual. We need intellect, and there is no reason why we should not have it together with character; but if we must choose between the two we choose character without a moment's hesitation.
If Nature does not wish that weaker individuals should mate with the stronger, she wishes even less that a superior race should intermingle with an inferior one; because in such a case all her efforts, throughout hundreds of thousands of years, to establish an evolutionary higher stage of being, may thus be rendered futile.
The only method compatible with our notions of civilization and the race is to prevent the breeding of the unfit by sterilization and the deliberate guidance of the mating instinct. [...] The trend of opinion among eugenists is that we must make marriage more difficult. Certainly no one who is not a desirable parent should be permitted to produce progeny.
Often in evolutionary processes a species must adapt to new conditions in order to survive. Today the atomic bomb has altered profoundly the nature of the world as we know it, and the human race consequently finds itself in a new habitat to which it must adapt its thinking.
We can't afford to stand pat while the world races by. The United States of America did not become the most prosperous nation on Earth by sheer luck or happenstance. We got here because each time a generation of Americans has faced a changing world, we have changed with it. We have not feared our future; we have shaped it.
As I pass through my incarnations in every age and race, I make my proper prostrations to the Gods of the Market-Place. Peering through reverent fingers I watch them flourish and fall, And the Gods of the Copybook Headings, I notice, outlast them all.
In man (as the only rational creature on earth) those natural capacities which are directed to the use of his reason are to be fully developed only in the race, not in the individual.
