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

To suffer unecessarily is masochistic rather than heroic.

Set me like a seal upon thy heart, love is as strong as death.

Since Auschwitz we know what man is capable of. And since Hiroshima we know what is at stake.

Love goes very far beyond the physical person of the beloved.

What will it matter to him if he notices that he is growing old? Has he any reason to envy the young people whom he sees, or wax nostalgic over his own lost youth? What reasons has he to envy a young person? For the possibilities that a young person has, the future which is in store for him? "No, thank you," he will think. "Instead of possibilities, I have realities in my past, not only the reality of work done and love loved, but of sufferings bravely suffered. These sufferings are even the things of which I am most proud, though these things are things that cannot inspire envy."

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