The things I believed in dont exist any more. It's foolish to pretend that they do. Western Civilization finally went up in smoke in the chimneys at Dachau but I was too infatuated to see it. I see it now.

You say 'I' and you are proud of this word. But greater than this- although you will not believe in it - is your body and its great intelligence, which does not say 'I' but performs 'I'.

All the labor of all the ages, all the devotion, all the inspiration, all the noonday brightness of human genius are destined to extinction. So now, my friends, if that is true, and it is true, what is the point?

I don't complain about the horror of life; I complain about the horror of my life. The only fact I worry about is that I exist and suffer and can't even dream of being removed from my feeling of suffering.

There is no reality except in action. Man is nothing else than his plan; he exists only to the extent that he fulfills himself; he is therefore nothing else than the ensemble of his acts, nothing else than his life.

As long as there have been men and they have lived, they have all felt this tragic ambiguity of their condition, but as long as there have been philosophers and they have thought, most of them have tried to mask it.

the sky here's very strange. I often have the sensation when I look at it that it's a solid thing up there, protecting us from what's behind . . . [from] nothing, I suppose. Just darkness. Absolute night.

There are three deaths. The first is when the body ceases to function. The second is when the body is consigned to the grave. The third is that moment, sometime in the future, when your name is spoken for the last time.

Sans doute, rien n’est plus naturel, aujourd’hui, que de voir des gens travailler du matin au soir et choisir ensuite de perdre aux cartes, au café, et en bavardages, le temps qui leur reste pour vivre.

A kind of joy came upon him, as if borne in on a summer breeze. He dimly recalled that he had been thinking of failure-as if it mattered. It seemed to him now that such thoughts were mean, unworthy of what his life had been.

Suppose you turn your attention inward in search of this 'I'. You may encounter nothing more than an ever changing stream of consciousness, a flow of thoughts and feelings in which there is no real self to be discovered.

For I do not exist: there exist but the thousands of mirrors that reflect me. With every acquaintance I make, the population of phantoms resembling me increases. Somewhere they live, somewhere they multiply. I alone do not exist.

This very heart which is mine will forever remain indefinable to me. Between the certainty I have of my existence and the content I try to give to that assurance, the gap will never be filled. Forever I shall be a stranger to myself.
