"To draw does not simply mean to reproduce contours; Drawing is not simply the idea: drawing is really the expression, the inner form, the plan, the model. Look what remains after that! Drawing is three quarters and a half of the which constitutes painting. If I had to put a sign over my door to the atelier I would write: school of drawing, and I am sure I would create painters."
