This book is one of two required texts for my "Visual Arts Today" course at university. While I find the content interesting, I am very sorry to say I cannot rate it higher than two stars. Its slow, meandering text comes across as pompous, and at times seems to present subjective information as though it were objective fact. As such, it bothers me. Much of the book seems to concentrate on building a vocabulary, rather than explaining any deep or startling facts about "looking." The occasional tidbit of interesting information is not enough to warrant the sixty dollar plus price tag, at most it should be forty dollars, if not thirty or less.
I would only recommend this book to those who are deeply involved with the philosophical side of art, and only if they turned down more interesting texts. Like I said, I wish I could rate it higher but the presentation of the information and the price point seriously damage any score I can give it.
--Edit--
It's come to my attention that the price has gone down to fifty five dollars or something like that. Whoop-de-do. The book still sucks, and unless you find it at a used book store, don't bother picking this one up.
