I am absolutely convinced that the gas chambers of Auschwitz, Treblinka, and Maidanek were ultimately prepared not in some ministry or other in Berlin, but rather at the desks and in the lecture halls of nihilistic scientists and philosophers.

Man’s main concern is not to gain pleasure or to avoid pain but rather to see a meaning in his life.

For what then matters is to bear witness to the uniquely human potential at its best, which is to transform a personal tragedy into a triumph, to turn one’s predicament into a human achievement.

Then I grasped the meaning of the greatest secret that human poetry and human thought and belief have to impart: The salvation of man is through love and in love.

A man's concern, even his despair, over the worthwhileness of life is an existential distress but by no means a mental disease.

At any moment, man must decide, for better or for worse, what will be the monument of his existence.
