“The only certainty life contains is death.”

“I'm going to end a life that I thought could contain every kind of greatness but that in fact consisted only of my incapacity to really want to be great. Whenever I arrived at a certainty, I remembered that those with the greatest certainties are lunatics.”

“I am sustained by the certainty that life has meaning… as does death.”

“No matter which way I go I know now that I will never have peace.
For peace is certainty, and there is no certainty but death.”

“I think of death only with tranquility, as an end. I refuse to let death hamper life. Death must enter life only to define it.”

“Tolerance grows only when faith loses certainty; certainty is murderous.”

“Life is really fascinated only by death. It vibrates only when it comes in contact with death.”

“There is no certainty; there is only adventure.”

“I hope that death contains
less than this.”

“Certainties are arrived at only on foot.”
