Creativity is about abstraction of function from the social situation - this is a necessary preliminary to being creative about something.
The basic situation, then, is for a human to be embedded in the social context - being sensitive to the nature of the social context, sensitive and responsive to the feelings and wishes of others.
The basic situation is that humans are set-up to be embedded in this context - with various aims: keeping other people happy, aiming to have high status within the context, hoping for power over others and so on...
Creativity entails detachment from this whole social context - and instead focusing upon 'the problem', the function, the goal. That is the basic situation.
This is the basic set-up of creativity. Creativity is a basic set-up in which the creative person is intrinsically detached from social context - and whose interests are external to himself; where the self is bound-up with objective, non-social externals.
So creativity is a disposition, a way of approaching the world, a focus, an emotional concern with the non-social doings of the world.
