Brown thinks drawing should be recognized with reading, writing and speaking.

You can draw

"Begin with a proper sketch book. Draw in ink. Finish each drawing you begin, and keep every drawing you finish. No erasing, no ripping out a page, no covering a page with angry scribbles. What you draw is an invaluable and unique representation of how you saw at that moment in that place according to your abilities. That's all we want. We already know what a dog really looks like."
