“Metaphysical guilt is the lack of absolute solidarity with the human being as such--an indelible claim beyond morally meaningful duty. This solidarity is violated by my presence at a wrong or a crime. It is not enough that I cautiously risk my life to prevent it; if it happens, and I was there, and if I survive where the other is killed, I know from a voice within myself: I am guilty of being still alive.”

“But each one of us is guilty insofar as he remained inactive. The guilt of passivity is different. Impotence excuses; no moral law demands a spectacular death. Plato already deemed it a matter of course to go into hiding in desperate times of calamity, and to survive. But passivity knows itself morally guilty of every failure, every neglect to act whenever possible, to shield the imperiled, to relieve wrong, to countervail. Impotent submission always left a margin of activity which, though not without risk, could still be cautiously effective. Its anxious omission weighs upon the individual as moral guilt. Blindness for the misfortune of others, lack of imagination of the heart, inner differences toward the witnessed evil--that is moral guilt.”

“What is meaningful cannot in fact be isolated…. We achieve understanding within a circular movement from particular facts to the whole that includes them and back again from the whole thus reached to the particular significant facts.”

“Just as primitive man believed himself to stand face to face with demons and believed that could he but know their names he would become their master, so is contemporary man faced by this incomprehensible, which disorders his calculations. "If I can but grasp it, if I can but cognise it", so he thinks, "I can make it my servant.”

“Man's primary will to know struggles against the selfsatisfied formalism of empty learning which drugs man intothe illusory calm of fulfillment. It fights against empty intellectualism,against nihilism which has ceased wanting anything and thus has ceased wanting to know. It battles against mediocrity which never takes stock of itself and which confuses knowledge with the mere learning of facts and <> The only satisfaction which man derives from a radical commitment to knowledge is the hope of advancing the frontier of knowledge to a point beyond which he cannot advance except by transcending knowledge itself.”

“Der Augenblick ist die einzige Realität, die Realität überhaupt im seelischen Leben. Der gelebte Augenblick ist das Letzte, Blutwarme, Unmittelbare, Lebendige, das leibhaftig Gegenwärtige, die Totalität des Realen, das allein Konkrete. Statt von der Gegenwart sich in Vergangenheit und Zukunft zu verlieren, findet der Mensch Existenz und Absolutes zuletzt nur im Augenblick. Vergangenheit und Zukunft sind dunkle, ungewisse Abgründe, sind die endlose Zeit, während der Augenblick die Aufhebung der Zeit, die Gegenwart des Ewigen sein kann.”

“Three things are required at a university: professional training, education of the whole man, research. For the university is simultaneously a professional school, a cultural center and a research institute. People have tried to force the university to choose between these three possibilities. They have asked what it is that we really expect the university to do. Since, so they say, it cannot do everything it ought to decide upon one of these three alternatives. It was even suggested that the university as such be dissolved, to be replaced by three special types of school: institutes for professional training, institutes for general education possibly involving a special staff, and research institutes. In the idea of the university, however, these three are indissolubly united. One cannot be cut off from the others without destroying the intellectual substance of the university, and without at the same time crippling itself. All three are factors of a living whole. By isolating them, the spirit of the university perishes.”
