A new question has arisen in modern man's mind, the question, namely, whether life is worth living...No sensible answer can be given to the question...because the question does not make any sense.

Freedom does not mean license.

The average American never loses his sleep about affairs which relate to his society and to our whole country.

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.

The most important factor for the development of the individual is the structure and the values of the society into which he was born.

There can be no real freedom without the freedom to fail.

Sanity is only that which is within the frame of reference of conventional thought.
