George Dickie is a Professor Emeritus of Philosophy at University of Illinois at Chicago. His specialities include aesthetics, philosophy of art and Eighteenth Century theories of taste.
This book is well written and well organized. It is dated though. For example, emphasis on the open-question argument is far less important since the work of Kripke. Still, as someone new to philosophy of art and aesthetics, I learned some of the lay of the land, at least as it was thought to be in the early 1970s. It was worth the hours I put into it and it has motivated me to pick up a contemporary introductory text.
