There just is exponentially more money in the movie business than in the music business. As a result there are more people involved in the creative process.
The creative process is a cocktail of instinct, skill, culture and a highly creative feverishness. It is not like a drug; it is a particular state when everything happens very quickly, a mixture of consciousness and unconsciousness , of fear and pleasure; it's a little like making love, the physical act of love.
The creative scientist studies nature with the rapt gaze of the lover, and is guided as often by aesthetics as by rational considerations in guessing how nature works.
Only the mind that has emptied itself of the known is creative. That is creation. What it creates has nothing to do with it. Freedom from the known is the state of a mind that is in creation.
Once you abstract from this, once you generalize and postulate Universals, you have departed from the creative reality, and entered the realm of static fixity, mechanism, materialism.
Artists may here have a more subtle scent: they know only too well that it is precisely when they cease to act 'voluntarily' and do everything of necessity that their feeling of freedom, subtlety, fullness of power, creative placing, disposing, shaping reaches its height - in short, that necessity and 'freedom of will' are then one in them.
While every noble morality develops from a triumphant affirmation of itself, slave morality from the outset says No to what is "outside," what is "different," what is "not itself"; and this No is its creative deed.
Most writers - poets in especial - prefer having it understood that they compose by a species of fine frenzy - an ecstatic intuition - and would positively shudder at letting the public take a peep behind the scenes.
There Is No God. This negation must be understood solely to affect a creative Deity. The hypothesis of a pervading Spirit co-eternal with the universe remains unshaken.
Probably, indeed, the larger part of the labor of an author composing his work is critical labor; the labor of sifting, combining, constructing, expunging, correcting, testing. This frightful toil is as much critical as creative.
