What Is Post Modernism?

I've really been trying to understand the underlying psychology of post modernism and its relationship with neomarxism. I interviewed stephen hicks recently, and he wrote an interesting book called explaining post modernism which i liked quite a bit. Well, my explanation is that there is no authentic 19 60 point of view in any of the l universities. Rather, the most liberated minds of my generation, of the 19 60 did not go on to graduate school. We need more people who are open-minded about how society has changed since the end of World War II.
