There is a conceptual depth as well as a purely visual depth. The first is discovered by science; the second is revealed in art. The first aids us in understanding the reasons of things; the second in seeing their forms. In science we try to trace phenomena back to their first causes, and to general laws and principles. In art we are absorbed in their immediate appearance, and we enjoy this appearance to the fullest extent in all its richness and variety. Here we are not concerned with the uniformity of laws but with the multiformity and diversity of intuitions.
