Nature's purpose in relation to the visual arts is to provide stimulus — not imitation.. .From its ceaseless urge to create springs all Life — all movement and rhythm — time and light, color and mood — in short, all reality in Form and Thought. Hans Hofmann (2000)
Creation is dominated by three absolutely different factors: First, nature, which works upon us by its laws; second, the artist, who creates a spiritual contact with nature and his materials; third, the medium of expression through which the artist translates his inner world. Of those three components only one, the medium, is material. Hans Hofmann (1963)
