Art is the complement of science. Science as I have said is concerned wholly with relations, not with individuals. Art, on the other hand, is not only the disclosure of the individuality of the artist but also a manifestation of individuality as creative of the future, in an unprecedented response to conditions as they were in the past. Some artists in their vision of what might be but is not, have been conscious rebels. But conscious protest and revolt is not the form which the labor of the artist in creation of the future must necessarily take. Discontent with things as they are is normally the expression of the vision of what may be and is not, art in being the manifestation of individuality is this prophetic vision.
