Can anyone help me describe the Political, Social, and Philosophical Art movements after WW2?

That's not a question requiring a short answer. that's an essay question at best, and the starting point for a multi-volume text at the other extreme.

I assume you've looked at the art from the period? What do you see as the themes? What new media became available? How did the art relate to the social and political environments? How did society relate to the new art expressions that were emerging (remembering that artists have to remain within acceptable parameters because the audience is also the market place). Art does not exist in a vacuum. It is both a mirror held up to society, and also a window that offers new views of what it is to be human in that society.
