 What are called cognitive, conceptual, or narrative positions in environmental aesthetics are united by the thought that knowledge and information about the nature of the object of appreciation is central to its aesthetic appreciation. Thus, they champion the idea that nature must be appreciated, as one author puts it, “on its own terms” (Saito 1998b). These positions tend to reject aesthetic approaches to environments, such as that governed by the idea of the picturesque, that draw heavily on the aesthetic experience of art for modeling the appreciation of nature. Yet they affirm that art appreciation can nonetheless show some of what is required in an adequate account of nature appreciation. For example, in serious, appropriate aesthetic appreciation of works of art, it is taken to be essential that we experience works as what they in fact are and in light of knowledge of their real natures. Thus, for instance, appropriate appreciation of a work such as Picasso’s Guernica (1937) requires that we experience it as a painting and moreover as a cubist painting, and therefore that we appreciate it in light of our knowledge of paintings in general and of cubist paintings in particular (Walton 1970). Adopting this general line of thought, one cognitive approach to nature appreciation, sometimes labeled the natural environmental model (Carlson 1979) or scientific cognitivism (Parsons 2002), holds that just as serious, appropriate aesthetic appreciation of art requires knowledge of art history and art criticism, such aesthetic appreciation of nature requires knowledge of natural history—the knowledge provided by the natural sciences and especially sciences such as geology, biology, and ecology. The idea is that scientific knowledge about nature can reveal the actual aesthetic qualities of natural objects and environments in the way in which knowledge about art history and art criticism can for works of art. In short, to appropriately aesthetically appreciate nature “on its own terms” is to appreciate it as it is characterized by natural science (Carlson 1981 2000 2007, Rolston 1995, Eaton 1998, Matthews 2002, Parsons 2002 2006b).
