This book has been on my bedside table for months - over a year probably - and I've dipped into it regularly, for the bursts of great art yes, and even more so for Katz's short, opinionated, craft-driven words about it. Whether or not I agree, or even have any kind of technical frame of reference for understanding what he says, each precis (or digression) illuminates not only the piece - and the artist - in question but also, as the title promises, ways of looking at art in general.
