Eric Gill said what?

Art which is not propaganda is simply aesthetics and is consequently entirely the affair of cultured connoisseurs. It is a studio affair, nothing to do with the common life of men and women, a means of ‘escape.’ Art in the studio becomes simply ‘self-expression,’ and that becomes simply self-worship. Charity, the love of God and your neighbour, which, here below, every work of man must exhibit, is lost. If you say art is nothing to do with propaganda, you are saying that it has nothing to do with religion – that it is simply a psychological dope, a sort of cultured drug traffic. I, at any rate, have no use for it. For me, all art is propaganda; and it is high time that modern art became propaganda for social justice instead of propaganda for the flatulent and decadent ideals of bourgeois Capitalism.
