In my opinion, here are some really nice and insightful quotes by Artaud! 

Written poetry is worth reading once, and then should be destroyed. Let the dead poets made way for others.

Those who live, live off the dead.

All true language is incomprehensible, like the chatter of a beggar's teeth.

I myself spent nine years in an insane asylum and I never had the obsession of suicide, but I know that each conversation with a psychiatrist, every morning at the time of his visit, made me want to hang myself, realizing that I would not be able to cut his throat.

There is in every madman a misunderstood genius whose idea, shining in his head, frightened people, and for whom delirium was the only solution to the strangulation that life had prepared for him.
