Drawing is, in fact, the discipline that connects sight and knowledge.
The act of seeing, since it allows us to enter into a knowledge of the world of things in which we live, is the first and foremost means by which we come to possess these things. To take this one step further, the connection between drawing and knowledge can be thought of as the natural extension of the relationship between sight and the outside world. It can be said, then, that drawing is knowledge. Therefore, there exists no better demonstration of our knowledge of the external world than the ability to draw it. Through drawing we strive to possess the world that exists outside us, and to make it part of ourselves.
