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.

Human history begins with man's act of disobedience which is at the same time the beginning of his freedom and the development of his reason.

It is a tragedy that most of us die before we have begun to live.

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

Respect is not fear and awe; it...[is]the ability to see a person as he is, to be aware of his unique individuality. Respect, thus, implies the absence of exploitation. I want the loved person to grow and unfold for his own sake, and in his own ways, and not for the purpose of serving me.

If our supreme value is the development of the Western tradition - of a man for whom the highest thing in life is man, for whom love for man, respect for man, and the dignity of man, are supreme values - then we cannot ask the question that says, "if it is better for our survival, might we drop these values?"

Free man is by necessity insecure, thinking man by necessity uncertain.
