Noted: Ezra Pound

From his preface to his book, The Spirit of Romance:

Art or an art is not unlike a river, in that it is perturbed at times by the quality of the river bed, but is in a way independent of that bed. The color of the water depends upon the substance of the bed and banks immediate and preceding. Stationary objects are reflected, but the quality of motion is of the river. The scientist is concerned with all of these things, the artist with that which flows.
