Galenson's Theory of Creativity

There's a theory about creativity that i've always loved. It's an idea that an economist named david galson came up with. He says there are two very different trajectories that great artists seem to take. Experimental innovators never have a clear, easily articulated idea. When they start off, they don't really know where they're going. They do endless draughts. And it can take them a lifetime to figure out what they want to say.
