To draw does not mean only to reproduce an outline, drawing does not
consist only of line; drawing is more than this, it is expression, it is
the inner form, the structure, the modelling. After that what is left?
Drawing includes seven-eighths of what constitutes painting. If I had to
put a sign above my door I would write on it "School of Drawing," and I
am sure that I should turn out painters.
