There have been three main ways of understanding human creativity.
The first was that the creative Man was a channel or conduit for the gods (e.g. muses), or God; that creativity was breathed-in (inspired) from the divine.
It was the divine/ God/s who were creative - who were original, and Men were instruments of the divine. The divine created: Men were tools of creation.
A creative Man was therefore one attuned with the divine, and who had the skills and application necessary to accomplish what he was being 'told' to do.
The second view was of the creative Man as an observer of realities, who 'copied' reality (with skill and diligence). The most-creative person was one who best held-up 'a mirror to nature'.
Men were not truly creative (they did not originate); but some Men were good observers: honest, hard-working and skilled observers.
The idea of a creator was Not to be 'original' - indeed Man could not, and should not try to, originate; because his job was to perceive and record existing reality.
The Romantic idea of genius was that the genius should be original: should originate. That is, the genius should add-to already-existing reality, in new ways, unique to that person.
That which the Romantic genius creates is assumed to come from the Man himself - and not 'merely' be something that already-existed in the divine, or in nature.
This means that - in this particular respect - Man is a god: the genius is ascribed the same primary creative capacity as the prime creator/s*.
So, to the Romantic understanding, Man can be a true creator, thus truly original. Yet - especially from the early 20th century - there arose the Modern consciousness; and with it the question of what direction this originality should assume: what were the proper constraints on it.
For Modern Man, the idea of the genius in his creative capacity as a type of the divine became impossible to think at a general cultural level; because the divine was either ironized or excluded. Modernity was atheistic, materialistic - the spiritual was not real.
Thus 'originality' became detached from the genius being an originator (because to modern consciousness the material world was everything); and was redefined in terms of clashing with what went before: as novelty, newness, shockingness.
A false dichotomy thus arose between the direction of originality: should the genius create to please the 'audience', satisfy the 'public'? Or else to please himself? (Or - in practice - create for a small group of those Men who appreciate newness and shock - the avant garde.)
This led to the idea of popular art that pandering to the masses; versus real art that was 'art for art's sake', and was indifferent to shocking the bourgeoisie (indeed enjoyed doing this - and the shock was taken as a sign of originality).
The assumption that the genius was therefore a Man who was in opposition to the masses - either working alone or supported only by a small and enlightened 'audience' of open-minded radicals. This has evolved to the current assumption of genius as intrinsically subversive, destructive; even, one who inverts what was accepted and established.
Therefore, for a Christian, this Modern definition of a genius begins to sound very close to being a definition of evil!
This popular versus personal, mass versus avant garde, was a false dichotomy because it excluded the divine and necessarily understood the purpose of genius in purely this-worldly terms.
The true direction of genius is Not a choice between pandering to the public or pleasing oneself; but whether to create in harmony with already-existing-and-ongoing divine-creation; or else in conflict with God.
In other words: the choice was between being a good genius or an evil genius. The good genius creates in harmony with God's creation (which is the source of the good: which defines the good).
But the evil genius sets himself against divine creation - past, present and/or future.
There are only two choices. Because not to be in harmony with divine creation is - of itself - to be a source of dis-harmony, of dissonance - to be working-against God's on-going creation.
The twentieth century saw the decline of genius; and part of this was surely the profound misunderstanding of creativity that came from the exclusion of the divine from public discourse.
This led to the false dichotomy of the popular versus personal/ elite creator - and this led to the phenomenon of the evil genius dominating the twentieth century; with more and more of the most influential geniuses from c. 1918 creating in disharmony with the divine: Picasso, James Joyce, Schoenberg and Stravinsky all fell into this category in their later work.
Then, in the later twentieth century, genius became rarer and less gifted; first in the arts (where the evil genius first dominated) then in the science also (as science became less honest, increasingly externally-controlled, and used for increasingly evil purposes).
So we have ended up in the 21st century with very few and marginalized geniuses of lesser stature. Why? Probably because genius originates in God's placement of potentially-genius souls in particular circumstances.
When genius becomes predominantly evil, and when a single genius can have such massive cultural effects, then it is reasonable to assume that the gift of genius has been withdrawn from the Western, European-originated societies where it was previously most dominant and evident.
When human creativity is being regularly used against divine creation; human creativity is withdrawn by God - as a form of a damage-limitation.
This rapid collapse of Western creativity over recent decades has had the unfortunate consequence of reducing the possibility of The West - as a society - escaping from its downward self-imposed, spiral towards self-annihilation.
Yet if the West was more creative, if there were more and greater geniuses; these would almost-certainly not be used to solve of social problems; but instead be used in ways that would increase our problems and accelerate our collapse into evil even more rapidly.
*And, since the genius is a Man - this understanding also implies that Men generically have a nature previously only ascribed to the divine. This further implies that because Men are 'gods' there are many gods. By my understanding, this further implies not just polytheism - in the sense of multiple creative-originators. There is only one primary creative source of our reality, of the creation in which we dwell; whom we term God. But if the reality of Romantic genius is accepted; then this implies a pluralistic universe of many divine-creative-agents who have co-existed with God (the primary creator), eternally. This neatly explains why originative creativity is possible to many entities. Why (to use Tolkien's term) Man is truly a subcreator. Or, to put things the other way around; if one believes in the reality of originative, genius human creativity; this implies (or more accurately, is at least, readily-consistent-with) a 'polytheistic', pluralistic universe. And the phenomenon of good and bad genius comes from that universe being the product of the creator-God - within-which geniuses divide between those who create in harmony with God's creation; and those who do not choose to harmonize their creativity with creation - hence create in conflict with God's creation.
