[Artaud] knows that thinking is not innate, but must be engendered in thought. He knows that the problem is not to direct or methodically apply a thought which pre-exists in principle and in nature, but to bring into being that which does not yet exist (there is no other work, all the rest is arbitrary, mere decoration). 

To think is to create - there is no other creation - but to create is first of all to engender 'thinking' in thought.

Artaud said the problem (for him) was not to orientate his thought or to perfect the expression of what he thought, or to acquire application and method or to perfect his poems, but simply to manage to think something.
