In the first reading of Chapter 5 "Aesthetic Appreciation of Natural Environment" , Allen Carlson states " we typically know both the what and the how of appropriate aesthetic appreciation" and then continues by saying that what this means is that we know what qualities to look at as relevant. I guess with my last post in mind as I write this now, I wonder whether whats relevant is really that universal? does one really know the what and how of appropriate aesthetic appreciation? who decides this how and what?

What is relevant about this Manet?
