Each man is questioned by life; and he can only answer to life by answering for his own life; to life he can only respond by being responsible.

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.'

Man is that being who invented the gas chambers of Auschwitz; however, he is also that being who entered those chambers upright, with the Lord's Prayer or the Shema Yisrael on his lips.

A human being is a deciding being.

No one can become fully aware of the very essence of another human being unless he loves him.

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