One of the main reasons why I ended up bored with marketing authors and psycho-marketers (safe some very worthy exceptions, as always happens) is their persistent focus on such topics as the number of messages the brain can process in one second or the time we need to get bored with things (as for instance, marketing books, I would add).
This kind of thought is the son of the cartesian stress on conscious mental processing and their vicisitudes. It forgets the fact that long before the rationalistic reductionism and self satisfaction, creation and beauty where not a product of conscious fast decisions, but emerged in the pressence of the divine element.
That creation is closer to some inspiring divinity than to step-by-step processes can be checked by anyone. You just have to start writing and will see how the words flow as if they had their own life. This is particularly evident in extremely talented people who, sometimes, are not able to anticipate the result of their job just seconds before the work is done. There is something that goes beyond the human control, something divine. The old psychoanalysts would call it "The unconscious factor". But how can something unconscious be beautiful? It is not unconscious, but sublime, creative.
The inspired nature of creation has long been a subject of recognition by subtle souls like Socrates. This is how he explains it in Plato´s Ion:
The divinity drags the soul of the men wherever she wants, linking in this her force one another. And with this, a huge chain of dancers is formed, a chain of choir masters and subordinates, one beside the other, pending from the rings of the muse. Every poet depends on his muse. We express this by saying he is possesed or, in other words, that he is dominated.
