"There are 2 clear differences between a work of art and a scientific paper. One is that in the work of art the painter is visibly both taking the world apart and putting it together on the same canvass. And the other is that you can watch him thinking as he is doing it. In both these respects the scientific paper is often deficient. It often is only analytic and almost always hides the process of thought in its impersonal language."
