Modern Art is all bosh, isn't it?

'They never go near the Louvre,' I said, 'or, if they do, it's only because one of their absurd reviews has suddenly "discovered" a master who fits in with that month's aesthetic theory. Half of they are out to make  a popular splash like Picabia; the other half quite simply want to earn their living doing advertisements for Vogue and decorating nightclubs. And the teachers still go on trying to make them paint like Delacroix.'
'Charles,' said Cordelia, 'Modern Art is all bosh, isn't it?'
'Great bosh.'
'Oh, I'm so glad. I had an argument with one of our nuns and she said we shouldn't try and criticize what we didn't understand. Now I shall tell I have had it straight from a real artist and snubs to her.'

E. Waugh, Brideshead revisited (1945), 177
