In considering creativity from a scientific perspective, much can be said - but at the heart of the phenomenon there is a mystery.
I have said that the truly creative essence of creativity is a 'black box' - in the sense that there cannot be a scientific description of genuine originality; but creativity is less like a black box than a living thing - a 'genie' within.
But this is not a genie who can be commanded like the slave of the lamp; but a genie who must be respected, nurtured and coaxed in order that he yield-up his gifts.
Indeed, in the case of a genius, the genie is the one in control. The genie ensures that he gets what he needs from his genius host - that the genie may find and follow his destiny; that he is fed with the knowledge, pictures, experiences he requires; that he is allocated enough time, the right situation, energy, attention...
And when the genie makes a discovery and gets a result; he ensures that the genius is flooded with happiness as reward; and that the genius is motivated to realize, and to communicate the genie's results.
In his essay On Fairy Stories, JRR Tolkien talked of subcreation; and suggested that it was an instance of Man emulating the divine Creator. Exactly so - Man is divine, not just in potential but in actuality - albeit feebly and partially and corruptedly; and creativity is a property of Man's divinity, just as much as 'free will' (or 'agency') is a property.
And creativity is a divine attribute, and the genius who lives in accord with his creative genie is a type of God-attuned Man: genius is a spiritual path; a path with the potential pitfalls of all spiritual paths, especially spiritual pride - but in its essence Good.
It is therefore an error to see a true genius as selfish. Insofar as he is humbly and faithfully serving his genie of creativity - he is following a divinely appointed destiny - for the ultimate benefit of all.
Whether or not a genius succeeds in making a recognized discovery - 'the way of the subcreator' is an intrinsically valid form of human life.
