"It is quite true what Philosophy says: that Life must be understood backwards. But that makes one forget the other saying: that it must be lived --forwards. The more one ponders this, the more it comes to mean that life in the temporal existence never becomes quite intelligible, precisely because at no moment can I find complete quiet to take the backward-looking position."
"One's condition on marijuana is always existential. One can feel the importance of each moment and how it is changing one. One feels one's being, one becomes aware of the enormous apparatus of nothingness -- the hum of a hi-fi set, the emptiness of a pointless interruption, one becomes aware of the war between each of us, how the nothingness in each of us seeks to attack the being of others, how our being in turn is attacked by the nothingness in others."
"Nowadays not even a suicide kills himself in desperation. Before taking the step he deliberates so long and so carefully that he literally chokes with thought. It is even questionable whether he ought to be called a suicide, since it is really thought which takes his life. He does not die with deliberation but from deliberation."
