Drawing is a combination of Perception and Conception. We can also think of this as Vision and Abstraction. For example:
We will begin next week with Line. Line is abstract. (Abstract - Expressing a quality apart from an object.) When we draw a line, we are not recording a line that we see. Line is not a representation of a sense impression in the direct sense that color is.  Line drawing is an abstract activity. When we draw a line, it is our perceptual judgement moving to visual abstraction.

I would like you to think of the drawings that you will do in class as visual records of a search. It will be important for you to give up your preconceptions about what you a are seeing, and become open to seeing in a new way. I'd like for you to give yourselves over to the process of seeing and drawing. Concentration is very important.
