Those who have a 'why' to live, can bear with almost any 'how'.

Challenging the meaning of life is the truest expression of the state of being human.

The last of human freedoms - the ability to chose one's attitude in a given set of circumstances.

Everything can be taken from a man but one thing: the last of human freedoms - to choose one's attitude in any given set of circumstances, to choose one's own way.

The more one forgets himself - by giving himself to a cause to serve or another person to love - the more human he is.

A man who becomes conscious of the responsibility he bears toward a human being who affectionately waits for him, or to an unfinished work, will never be able to throw away his life. He knows the 'why' for his existence, and will be able to bear almost any 'how.'
