“.. the thinking man is no longer the center of the universe, but the universe is the center of the man [referring to collaborations between artists, in which Klein was involved several times]. We shall then know 'prestige' in comparison to the 'vertigo' of before. Thus we shall become men of the air, we shall know the upward force of attraction, towards space, towards nowhere and everywhere at once; having thus mastered the earthly force of attraction we shall literally levitate in complete physical and spiritual freedom.”

I Think I'll Sit This One Out (1939)
Context: It is a sensible military tactic to recognize the enemy before you shoot. The common enemy is the animality in man, and not the men here and there who are behaving like animals at the moment. Neither science nor prayer nor force will save us. What will save us is the reason that enables men, in ancient Israel and modern America, to choose between guns and butter, and to choose well. When we have produced men of reason, we shall have a world of reason, and the Hitlers will disappear. As long as we produce men of force we shall have a world of force, and the Hitlers, whoever wins the wars, will carry the day.
Society may make many demands on me, as long as it keeps me out of the cave. It may take my property. It may take my life. But when it puts me back into the cave I must say, politely but firmly, to hell with society. My ancestors were cannibals without benefit of parliaments.

Education (1902)
Context: After the long night, and longer twilight, we envisage a dawn-era: an era in which the minor law of tradition shall yield to the greater law of creation, in which the spirit of repression shall fail to repress.
Man at last is become emancipated, and now is free to think, to feel, to act free to move toward the goal of the race.
Humanitarianism slowly is dissolving the sway of utilitarianism, and an enlight- ened unselfishness is on its way to supersede a benighted rapacity. And all this, as a deep-down force in nature awakens to its strength, animating the growth and evolution of democracy.
Under the beneficent sway of this power, the hold of illusion and suppression is passing; the urge of reality is looming in force, extent and penetration, and the individual now is free to become a man, in the highest sense, if so he wills.
