I'm not sure it can. Human creativity seems to re-mix elements from experience, as your examples demonstrate...

The visualisation of a 'red cup', for instance, is instigated by stimulating 'visual pathways' that have previously been instrumental in producing the actual experience of a red cup. However, when it comes to
imagination, how would the brain know which pathways to stimulate in order to produce the image of a pink fairy?
If you had never seen pink could you visualise a pink fairy? Of course a fairy is merely a human figure with insect-like wings, so nothing beyond experience is involved in the construction.
I think that you've got the wrong end of my stick. You said that to visualise a red cup involved stimulating pathways that had previously been stimulated by red cups. This process, then, wouldn't require any creativity at all (though note, it would require
will) - it would just require memory/awareness of which pathways were previously stimulated during the observation of a red cup, so that the same pathways could be stimulated. However, when it comes to visualising things such as a pink fairy, the brain then has to start being
creative, since there are no specific pathways commensurate with pink fairies. Sure, there are pathways involving pinkness; human females; wings. But these are all distinct pathways. So the brain couldn't just rely on memory. It would have to
orchestrate all the required pathways to produce a unique image within the mind. Furthermore, prior to doing this, the brain would
already have to have some kind of idea of what it was that it was trying to create an image of. If I ask you to visualise a fairy, for instance, the
notion of 'fairy' has to exist prior to its visualisation. Producing a unique notion is in itself creative, in that the notion of 'fairy' is a notion about something that cannot be observed. That is, the notion is non-worldly. It is born in the mind.
It takes no creative effort to visualise something that you've already experienced. But it does require creativity to come up with a theme/idea/notion/etc. and then utilise and orchestrate many different aspects of previous experience to produce a visualisation, or piece of 'art'. If I was to compose a piece of music to surpass anything done by Beethoven or Mozart, would you really not consider it to be 'art' because I had utilised a musical scale not devised by myself and memories of pre-existing 'notes'? Does art really have to be absolute, before it
is art?
... Visualising entities that you've never directly experienced before, clearly involves creativity, in that it would clearly involve a '
composition' of one's own making.
Of course my philosophy is not some some pure creation of my own mind in isolation. Nor is yours. Nor is any idea anyone has ever had.
That last comment
has to be wrong, since there must have been a
first idea, sometime, somewhere. There has to be a first for practically anything in the world. That must include ideas/concepts/notions/words - even 'a philosophy'.
They are formed from observation of the world around us and combinations of the ideas of others. I don't denigrate human creativity by saying that, it a glorious thing, but it doesn't create from nothing.
I object to you merely asserting that the world exists "around us" (externally to us) and is [therefore] the source of all 'art'. As I remember saying to you in a previous discussion, even the brain is confined to knowing nought but itself (its own states or configurations). The brain can only react to itself. That is, even if there is a reality "out there", the brain can only process and respond to its own internal states that are [presumably] responses to that realm. Any 'art', therefore, would have to be a process that involved recognition and manipulation of
one's own self. This holds true even from a materialistic outlook.
They came, they saw, they concurred.
