The book is pretty good for any old crap.
That is, unless you have made up your mind that it is going to be crap and have no intention of reading it to find out.
I was trying a define the work of a recent Scottish artist (named William Johnstone, whose widow was a neighbour) to an American friend, a few years ago. At one point I said that he had studied art in Paris at the same time time as Picasso, in the same studios.
Her reply? "Picasso was a communist, wasn't he?"
That was enough for her. He couldn't possibly be any good as an artist.
