The obvious answer, attempted here, is to prepare my own anthology. Return to basics. Surely, it would seem so. My aesthetics course is concermed with these and similar questions, and the readings tend to be grouped accordingly. I confess that early in the course I also have a few lectures dedicated to some major philosophers who did work on aesthetics, e.g. John Dewey, Henri Bergson, George Santayana, etc.
Philosophers can never resist making a few additional observations.
Suffice it to say that, in my view, the history of aesthetics has not exhibited a steady, orderly development. In the 20th century, there were a number of classic and near-classic works. But the fact is that, in the 20th century, much of the significant work in aesthetics appeared first as articles in the so-called learned journals. That journal seems to have been quite consciously modeled on the Zeitschrift fur Aesthetik und Allgemeine Kunstwissenschaft which was published from 1906, by the German scholar Max Dessoir, until about 1943, when, by the accounts I have heard, the Nazi government forced this great periodical to be discontinued. The Society, and the Journal, still boast many scholars deserving of respect, Some of their essays are reproduced in my anthology.
