Aesthetics and the Environment [PDF ebook] 
The Appreciation of Nature, Art and Architecture

Traditional aesthetics is often associated with the appreciation of art, Allen Carlson shows how much of our aesthetic experience does not encompass art but nature, in our response to sunsets, mountains or horizons or more mundane surroundings, like gardens or the view from our window.
He argues that knowledge of what it is we are appreciating is essential to having an appropriate aesthetic experience and that scientific understanding of nature can enhance our appreciation of it, rather than denigrate it.
