Decent, light read. Says some fairly obvious things about art re: subjectivity/objectivity, the reality of technical skill, diversity of taste(s), etc.
The writing is lucid and more or less engaging but one wonders the overall point. I like the affirmation of "quality" in art but what Vergara-Sharp briefly (and I mean briefly - the book is only 120 pages long) essays here is quite uncontroversial, since no one in their right mind would argue that to be a good painter in Europe circa the 15-18th centuries didn't take years of training, as well as a certain ideological bias for Antiquity and the standards it created.
Definitely in need of a more comprehensive detailing.
