why is it that we see sunsets, mountains, life forms, geological formations, etc. and consider them to be beautiful.
A helpful answer might be that we see sunsets and mountains and so on as beautiful because they are beautiful. The reason I say that this answer is helpful is twofold. It moves the question away from the bias of a model in which (a) there is no beauty in nature, but (b) we project it onto nature, which together raise the question © 'Why these projections and not others?' That is all built into the question. The second helpful thing, as I see it, about the answer that I have suggested is that it puts the issue squarely on top of the traditional question what beauty is.
