There are many motivations for making art, both conscious and unconscious. In men, the cynic in me is inclined to think that art is just about demonstrating genetic fitness to the opposite sex. For whatever reason, creativity seems to perceived as attractive, and any endeavor that a male undertakes to distinguish himself in some way can at least be partly coupled to his innate reproductive drive. This pop evo-psych story reads like a "just-so" theory (hence it's appeal) but there's likely at least some truth to it.
(does this theory explain female creativity, like literature and music, for example, equally well? I don't know. Certainly the girls I've loved the most were both artists but maybe that's just me)
I'd like to give men more credit, though. Human motivation is a complex thing. If you agree with eliminative materialists, for example, they don't really even think it exists - we are simply biomechanical machines and whatever the phenomenology of purpose/motivation we experience is just like a thin mist of water hovering over the waves of the ocean, where all the real movement occurs. This is the camp that thinks that there's no such thing as mental causation, really, that every human action is just the consequence of atomic interactions in your brain cascading through your nervous system, and nothing more.
Psychologists and philosophers and people who oversell fMRI findings like to think they've solved every mystery in life. But they're wrong.
There are still mysteries... things we don't understand. I know that, subjectively, I feel a sometimes transcendental motivation to make something beautiful. There are many different kinds of beauty, some of them more raw than others, but I like to write about moments that can really move people. On the level of prose, too, I like the feel of a sentence when it flows properly. I like the movement of a paragraph written well, the rhythm of it. You might think me a sentimentalist, and you might be partly right, but there's room for sincerity in art that falls short of being Nicholas Fucking Sparks.
Or maybe Satoshi Kanazawa was right, and "everything a man does he does in order to get laid" / "MEN ONLY MAKE ART TO GET PUSSY" (I'm paraphrasing a bit here).
I don't know, maybe the guy is right.
I'd like to think he's wrong, though.
