They say necessity breeds invention. I guess the same can apply to a mind's need for art. One could say that it is a primordial need to express oneself. To leave a trail of emotions on a page, a canvas, a wall, simply in the hopes of evoking another emotion. Now that's saying something. That's an experience, not just for the artist, but for the beholder, the unassuming victim of the artist who can't help but be absorbed by the piece, the colors--or lack thereof--to be consumed by the strained and relentless aesthetics of that same work of art. One can only hope never to return to the monochromatic world restricting the masterpiece.
Why, to shed a tear over a work of art is the largest compliment to the artist. To invoke an abstract emotion that is rival to one of the physical world is a reflection of the captive hold of the creator, the mastermind behind the diabolical beauty of the piece, the one who thrives on the splendor of it all, who thrives on art as much as the art is dependent on the artist.
So, yes, the necessity to create does breed the invention, but the invention, like a child, is born of the creator. The invention molds throughout the years, bending and shaping, affecting and inspiring its beholders, as well as the artist, its creator. And the creator is just as much dependent on the creation as the creation thrives on inspiration from the artist. This inspiration, this will to create, IS the necessity.
Whoever "They" are, they sure got it right.
