I was just looking out my window to admire the loveliness of the mountains and trees. It makes me think does the natural world conform to any known aesthetic principles of color, balance, texture, harmony, etc? Or is nature lovely for more mysterious reasons? And supposing it did conform to aesthetic principles are those principles actually derived from nature?...For instance the colors white and blue often go together well and I wonder if this is a good combination because it reminds one of the sky or if the sky just happens to use a good color scheme of blue and white. I am thinking right now, how before a storm, the clouds turn an ominous black, and that does seem awfully symbolic (and aesthetically logical) to my primitive and pre-philosophical mind. It makes me wander if there are other less obvious things like this that I haven't noticed or I don't have the artistic sophistication to see. Have any 19th century romantic philosophers (or any other philosphers for that matter) had anything interesting to say on the aesthetics of nature?
