The difference between what we see and a sheet of white paper with a few thin lines on it is very great. Yet this abstraction is one which we seem to have adopted almost instinctively at an early stage in our development, not only in Neolithic graffiti but in early Egyptian drawings. And in spite of its abstract character, the outline is responsive to the least tremor of sensibility.

Our universe cannot even be stated symbolically. And this touches us all more directly than one might suppose. For example, artists, who have been very little influenced by social systems, have always responded instinctively to latent assumptions about the shape of the universe. The incomprehensibility of our new cosmos seems to me, ultimately, to be the reason for the chaos of modern art.
