This a good introductory book to those interested in the theory of art. My particular interest and reason for reading this book was the question what constitutes art? This book was enlightening to me as it was open to ideas about what sort of things could be included in a group of things that could be considered works of art.
The book itself is structured in a way to focus on issues related to my question such as the impact of shocking modern works, non western/ethnic art, and the influence of the art market, feminism and modern media. These issues then provide a backdrop from which to explore and discuss different art theories, this is a much more engaging way of discussing and evaluating different theories as the backdrop provides a context to evaluate various theories, rather than just running through different theories without context.
The unsettling element of the book is that it does not seem possible to establish any fixed point from which to discuss art, as to do so instantly set limits from which the theory will ultimately be dismissed. The best theories art are those that do not impose limits, but this seems to let the floodgates open to any anything goes attitude which is equally dissatisfying. The message I took from the book is that art theory walks a tightrope between two unsatisfactory positions - but I have faith that it is possible to walk that tightrope.
There are a few problems such some issues seem to be glossed over such as the difference between arts and crafts, but this need not be taken as flaw, but as a limitation of space and the launch point for further study.
