I propose a new account of the limits of aesthetic testimony. One of this new account's main claims is that, among the kinds of aesthetic cognitive achievements, it is useful to distinguish aesthetic understanding. In particular, I suggest that the aesthetic understanding of X involves an understanding of why X is aesthetically valuable. In turn, aesthetic understanding is essentially connected to the deployment of aesthetic concepts. Given the fine-grained structure of some of these concepts, certain forms of testimony are not (...) adequate to acquire them. (shrink)
