Every artist, as child of his age, is impelled to express the spirit of his age.

The sensations of colors on the palette can be spiritual experiences.

An empty canvas is a living wonder - far lovelier than certain pictures.

As a picture painted in yellow always radiates spiritual warmth, or as one in blue has apparently a cooling effect, so green is only boring.

The sound of colors is so definite that it would be hard to find anyone who would express bright yellow with bass notes or dark lake with treble.

The artist must train not only his eye but also his soul.

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.
