- Sheer egoism: Desire to seem clever, to be talked about, to be remembered after death, to get your own back on the grown-ups who snubbed you in childhood, etc., etc.
- Aesthetic enthusiasm: Perception of beauty in the external world, or, on the other hand, in words and their right arrangement.
- Historical impulse: Desire to see things as they are, to find out true facts and store them up for the use of posterity.
- Political purpose: Desire to push the world in a certain direction, to alter other peoples’ idea of the kind of society that they should strive after.
Thank you George.
