The object, which is back of every true work of art, is the attainment of a state of being, a state of high functioning, a more than ordinary moment of existence. In such moments activity is inevitable, and whether this activity is with brush, pen, chisel, or tongue, its result is but a by-product of the state, a trace, the footprint of the state.
Robert Henri (1960). “The art spirit”, Lippincott Williams & Wilkins
