“Arguments for preservation based on the beauty of wilderness are sometimes treated as if they were of little weight because they are "merely aesthetic". That is a mistake. We go to great lengths to preserve the artistic treasures of earlier human civilisations. It is difficult to imagine any economic gain that we would be prepared to accept as adequate compensation for, for instance, the destruction of the paintings in the Louvre. How should we compare the aesthetic value of wilderness with that of the paintings in the Louvre? Here, perhaps, judgment does become inescapably subjective; so I shall report my own experiences. I have looked at the paintings in the Louvre, and in many of the other great galleries of Europe and the United States. I think I have a reasonable sense of appreciation of the fine arts; yet I have not had, in any museum, experiences that have filled my aesthetic senses in the way that they are filled when I walk in a natural setting and pause to survey the view from a rocky peak overlooking a forested valley, or by a stream tumbling over moss-covered boulders set amongst tall tree-ferns, growing in the shade of the forest canopy, I do not think I am alone in this; for many people, wilderness is the source of the greatest feelings of aesthetic appreciation, rising to an almost mystical intensity.”

“I suspect that many of the great cultural shifts that prepare the way for political change are largely aesthetic”

“As I sit, my back leaning against a damp, moss-covered tree trunk, my eyes sweeping the canopy above, my ears straining to catch the crack of a distant branch that betrays an orangutan moving in the treetops, I think about how we humans search for God. The tropical rain forest is the most complex thing an ordinary human can experience on this planet. A walk in the rain forest is a walk into the mind of God.”

“i have a friend who’s an artist and he’s sometimes taken a view which i don’t agree with very well. he’ll hold up a flower and say, “look how beautiful it is,” and i’ll agree, i think. and he says - “you see, i as an artist can see how beautiful this is, but you as a scientist, oh, take this all apart and it becomes a dull thing.” and i think that he’s kind of nutty. first of all, the beauty that he sees is available to other people and to me, too, i believe, although i might not be quite as refined aesthetically as he is; but i can appreciate the beauty of a flower. at the same time i see much more about the flower than he sees. i can imagine the cells in there, the complicated actions inside which also have a beauty. i mean it’s not just beauty at this dimension of one centimeter, there is also beauty at a smaller dimension, the inner structure. also the processes, the fact that the colors in the flower evolved in order to attract insects to pollinate it is interesting - it means that insects can see the color. it adds a question: does this aesthetic sense also exist in the lower forms? why is it aesthetic? all kinds of interesting questions which shows that a science knowledge only adds to the excitement and mystery and the awe of a flower. it only adds; i don’t understand how it subtracts..”

“We were approaching the Louvre, but he paused to lean on the parapet, and we both stood there contemplating the passing boats, which dazzled us with their spotlights. ‘Look at them,’ I said, because I needed to talk about something, afraid that he might get bored and go home. ‘They only see what the spotlights show them. When they go home home, they’ll say they know Paris. Tomorrow they’ll go and see the Mona Lisa and claim they’ve visited the Louvre. But they don’t know Paris and have never really been to the Louvre. All they did was go on a boat and look at a painting, one painting, instead of looking at a whole city and trying to find out what’s happening in it, visiting the bars, going down the streets that don’t appear in any of the tourist guides, and getting lost in order to find themselves again. It’s the difference between watching a porn movie and making love.”

“The arts especially address the idea of aesthetic experience. An aesthetic experience is one in which your senses are operating at their peak; when you’re present in the current moment; when you’re resonating with the excitement of this thing that you’re experiencing; when you are fully alive.”
