But I take the point about art as a non-way out of the horror. I just wonder ("apart from burning banks, trashing city institutions") what else is to be done?
Whilst art is certainly not going to bring about major social change, it's worth preserving something in life that isn't wholly subservient to all the other de-humanising, commercialised aspects of late capitalist culture. A world without some culture that does more than simply mirror the other structures of society would be poorer than a world with such a thing. Same goes for intellectual life, or indeed for human relations.
(if I didn't believe that, I wouldn't be involved with such things)
