We may know ourselves, and yet even with all the efforts we make, we do not know ourselves. We know our fellowman, and yet we do not know him, because we are not a thing, and our fellowman is not a thing. The further we reach into the depths of our being, on someone else's being, the more the goal of knowledge eludes us.

It seems that great minds a hundred years ago saw what would happen today or tomorrow, while we to whom it is happening blind ourselves in order not to be disturbed in our daily routine.

The fact that millions of people share the same vices does not make these vices virtues, the fact that they share so many errors does not make the errors to be truths, and the fact that millions of people share the same form of mental pathology does not make these people sane.

I feel worried, deeply worried, only about one thing - the possibility that we fall... that we cannot avoid an atomic war.

To love one person productively means to be related to his human core, to him as representing mankind. Love for one individual, in so far as it is divorced from love for man, can refer only to the superficial and to the accidental; of necessity it remains shallow.

What you might call the "symbol pushers" - that is to say, all of the people who deal with figures, with paper, with men, who manipulate - to use a better or nicer word - manipulate men and signs and words. All those today have not only to sell their service, but in the bargain, they have to sell their personality, more or less. There are exceptions.

I think our danger is that we talk one thing, and we feel and act another thing.
