Drawing used to be a civilized thing to do, like reading and writing. It was taught in elementary schools. It was democratic. It was a boon to happiness.
The artist’s “way of seeing” is different from ordinary seeing and requires an ability to make mental shifts by conscious volition. Perhaps more accurately, an artist sets up conditions that cause a cognitive shift to “happen.” That is what a person who is trained in drawing does, and that is what you are about to learn.
