Man may be defined as the animal that can say ''I,'' that can be aware of himself as a separate entity.

We live in a world of things, and our only connection with them is that we know how to manipulate or to consume them.

It is true that one has to think first and then to act - but it's also true that if one has no possibility of acting, one's thinking kind of becomes empty and stupid.

Man's biological weakness is the condition of human culture.

Man today being concerned with production and consumption as ends in themselves, has very little engergy time to devote himself to the true religious experience.

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.

To have faith requires courage, the ability to take a risk, the readiness even to accept pain and disappointment. Whoever insists on safety and security as primary conditions of life cannot have faith; whoever shuts himself off in a system of defense, where distance and possession are his means of security, makes himself a prisoner. To be loved, and to love, need courage, the courage to judge certain values as of ultimate concern – and to take the jump and to stake everything on these values.
