Do you feel art has a function in post modernity, if so is it effective?

Thanks for your question. I think art does sometimes serve a vanguardist function in postmodernity, but I think this is a residual effect of late modern conditions extending into postmodernity; art can still function as vanguardist critique because modern conditions persist in postmodernity. But I think the dominant tendencies of postmodernity are toward neutralizing the political power of art.
