So long as you "have" yourself, have yourself as an object, your experience of man is only as of a thing among things.

You do not attain to knowledge by remaining on the shore and watching the foaming waves, you must make the venture and cast yourself in, you must swim, alert and with all your force, even if a moment comes when you think you are losing consciousness; in this way, and in no other, do you reach anthropological insight.

The philosophical anthropologist ... can know the wholeness of the person and through it the wholeness of man only when he does not leave his subjectivity out and does not remain an untouched observer.

In philosophical anthropology, ... where the subject is man in his wholeness, the investigator cannot content himself, as in anthropology as an individual science, with considering man as another part of nature and with ignoring the fact that he, the investigator, is himself a man and experiences this humanity in his inner experience in a way that he simply cannot experience any part of nature.

The world is not divine sport, it is divine destiny. There is divine meaning in the life of the world, of man, of human persons, of you and of me. Creation happens to us, burns itself into us, recasts us in burning - we tremble and are faint, we submit. We take part in creation, meet the Creator, reach out to Him, helpers and companions.

Whoever abhors the name and fancies that he is godless - when he addresses with his whole devoted being the Thou of his life that cannot be restricted by any other, he addresses God.

Some would deny any legitimate use of the word God because it has been misused so much. Certainly it is the most burdened of all human words. Precisely for that reason it is the most imperishable and unavoidable. And how much weight has all erroneous talk about God's nature and works (although there never has been nor can be any such talk that is not erroneous) compared with the one truth that all men who have addressed God really meant him? For whoever pronounces the word God and really means Thou, addresses, no matter what his delusion, the true Thou of his life that cannot be restricted by any other and to whom he stands in a relationship that includes all others.

All names of God remain hallowed because they have been used not only to speak of God but also to speak to him.

Egos appear by setting themselves apart from other egos.

The basic word I-Thou can be spoken only with one's whole being. The concentration and fusion into a whole being can never be accomplished by me, can never be accomplished without me. I require a Thou to become; becoming I, I say Thou.
