Another important question is that of line. Many lovers or students of art feel the great influence of a line, the effect that a line can have. A vertical line, a horizontal one, a curve, a circle, all make such a difference in the form. And the more one studies to what extent line makes a difference, the more one will find that the secret of all beauty is in the line. But it is difficult to say what form or what line is the right form or line, and man has to accept that what one cannot learn by study, intuition can teach.
