The how, it turns out, is a 'TABULA' approach (as in - rasa) - time, association, background, understand, look again, assessment (although, for the most part, the book deliberately steers clear of that last). An enjoyable and plentifully illustrated skip through a range of ways of tackling/framing contemporary art - 'as entertainment', 'as confrontation', 'as event', 'as message', 'as joke', 'as spectacle', 'as meditation'. Plus, fit well with my scattershot approach to learning anything in particular about art, as I was able to fit various artists whose pieces I've seen previously into at least some kind of context as provided by the book.
