Drawing instruction is a training towards perception, exact observation and exact presentation not of the outward appearances of an object, but of its constructive elements, its lawful forces-tensions, which can be discovered in given objects and of the logical structures of same-education toward clear observation and clear rendering of the contexts, whereby surface phenomena are an introductory step towards the three-dimensional.

The artist is not a 'Sunday child' for whom everything immediately succeeds. He does not have the right to live without duty. The task that is assigned to him is painful, it is a heavy cross for him to bear.

Generally speaking, color directly influences the soul.

The artist must be blind to distinction between 'recognized' or 'unrecognized' conventions of form, deaf to the transitory teaching and demands of his particular age.

Absolute green is the most restful color, lacking any undertone of joy, grief, or passion. On exhausted men this restfulness has a beneficial effect, but after a time it becomes tedious.

The more abstract is form, the more clear and direct its appeal.

Color is the keyboard, the eyes are the harmonies, the soul is the piano with many strings. The artist is the hand that plays, touching one key or another, to cause vibrations in the soul.
