I know what I said about modernism wasn't entirely accurate..
just reading a biog of Wyndham Lewis, where he writes in an early letter:
"Verisimilitude–that's what you want to get with your wheezy efforts... But that isn't what people want. They don't want vicarious experience; they don't want to be educated. They want to be amused... By brilliant fellows like me. Letting off brilliant fireworks. Performing like dogs on tight ropes. Something to give them the idea they're at a performance. You fellows try to efface yourselves; to make people think there isn't any author and they're living in the affairs you... adumbrate.." etc etc
so the pedestal is turned into a stage.. or something. The passive artits is gone, so is the passive audience (but the artists still fancy themselves)
