The focus of Aesthetics as Philosophy of Perception is the concept of attention and the ways in which this concept and especially the distinction between distributed and focused attention can help us re-evaluate various key concepts and debates in aesthetics. Sometimes our attention is distributed in an unusual way: we are attending to one perceptual object but our attention is distributed across its various properties. This way of experiencing the world is special and it plays an important role in characterizing a number of phenomena associated with aesthetics. Some of these that the book talks about include picture perception and depiction, aesthetic experiences, formalism, the importance of uniqueness in aesthetics, and the history of vision debate.
But sometimes, in some aesthetic contexts, our attention is not at all distributed, but very much focused. Nanay closes his argument with an analysis of some paradigmatic aesthetic phenomena where our attention is focused: identification and engagement with fictional characters. And the conflict and interplay between distributed and focused attention is an important feature of many artworks.
