The circle is the synthesis of the greatest oppositions. It combines the concentric and the eccentric in a single form and in equilibrium. Of the three primary forms, it points most clearly to the fourth dimension.

Those [things] that we encounter for the first time immediately have a spiritual effect upon us. A child, for whom every object is new, experiences the world in this way: it sees light, is attracted by it, wants to grasp it, burns its finger in the process, and thus learns fear and respect for the flame.

With few exceptions, music has been for some centuries the art which has devoted itself not to the reproduction of natural phenomena, but rather to the expression of the artist's soul, in musical sound.

Color is the keyboard. The eye is the hammer. The soul is the piano, with its many strings.

That is beautiful which is produced by the inner need, which springs from the soul.

In general, therefore, color is a means of exerting a direct influence upon the soul. Color is the keyboard. The eye is the hammer. The soul is the piano with its many strings. The artist is the hand that purposefully sets the soul vibrating by means of this or that key.

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.
