“Human perfection and technical perfection are incompatible. If we strive for one, we must sacrifice the other: there is, in any case, a parting of the ways. Whoever realises this will do cleaner work one way or the other.Technical perfection strives towards the calculable, human perfection towards the incalculable. Perfect mechanisms - around which, therefore, stands an uncanny but fascinating halo of brilliance - evoke both fear and Titanic pride which will be humbled not by insight but only by catastrophe.The fear and enthusiasm we experience at the sight of perfect mechanisms are in exact contrast to the happiness we feel at the sight of a perfect work of art. We sense an attack on our integrity, on our wholeness. That arms and legs are lost or harmed is not yet the greatest danger.”

“Prognoses which have been made contend that our technology will terminate in pure necromancy. If so, everything we now experience would be only a departure and mechanics would become refined to a degree that would no longer require any crude embodiment. Lights, words, yes even thoughts would be sufficient. (1957)”

“When we come under the spell of the deeper domain of technology, its economic character and even its power aspect fascinate us less than its playful side. Then we realize we that we are involved in a play, a dance of the spirit, which cannot be grasped by calculation. What is ultimately left for science is intuition alone - a call of destiny.This playful feature manifests itself more clearly in small things than in the gigantic works of our world. The crude observer can only be impressed by large quantities - chiefly when they are in motion - and yet there are as many organs in a fly as in a leviathan.”

“We should embrace our mistakes, not fear them, learn from them, as we know we are not perfect. We do not come from perfection, we reach for perfection.”

“Complete and total perfection will come about only when we feel that our perfection is no perfections as long as the rest of humanity remains imperfect.”

“Each of us is merely one human being, merely an experiment, a way station. But each of us should be on the way toward perfection, should be striving to reach the center, not the periphery.”

“Strive for excellence, not perfection, because we don't live in a perfect world.”
