Visual Studies: A Skeptical Introduction

In his latest book, James Elkins offers a road map through the field of visual studies, describing its major concerns and its principal theoretical sources. Then, with the skill and insight that have marked his successful books on art and visuality, Elkins takes the reader down a side road where visual studies can become a more interesting place. Why look only at the same handful of theorists? Why exclude from ones field of vision non-Western art or the wealth of scientific images?
