I have been reading George Inness and the Visionary Landscape by Adrienne Baxter Bell. I knew there was something else going on in his landscapes, but I didn't realize the depth of his religious perception of landscape. Also his deliberate going-after suggestiveness in his handling of paint. Here's a wonderful quote in the book from William James, apropos of nothing directly with Inness, "We may be in the universe as dogs and cats are in our libraries, seeing the books and hearing the conversation, but having no inkling of the meaning of it all." Actually, my guess would be that cats and dogs might have a better sense of the universe than people.
