Art is science in the flesh.

One must be a living man and a posthumous artist.

If an addict who has been completely cured starts smoking again he no longer experiences the discomfort of his first addiction. There exists, therefore, outside alkaloids and habit, a sense for opium, an intangible habit which lives on, despite the recasting of the organism. The dead drug leaves a ghost behind. At certain hours it haunts the house.

Style is a simple way of saying complicated things.

It is not I who become addicted, it is my body.

I succeeded in bewitching a fair number and in being intoxicated with my mistakes.

In two weeks, despite these notes, I shall no longer believe in what I am experiencing now. One must leave behind a trace of this journey which memory forgets. One must, when this is impossible, write or draw without responding to the romantic solicitations of pain, without enjoying suffering like music, tieing a pen to one's foot if need be, helping the doctors who can learn nothing from laziness.
