This was now eh almost 35+ years ago and I still remember some of the essays I wrote for his class. Something I can say about almost no other classes.
In particular when discussing and learning about economic philosophy - stuff like Marxism and more I recall an essay I wrote about a way to organize firms where the workers could own the organization but it was still a market economy. (There was more to this - it wasn’t a short essay). But 35 years later I still think I was on to something.
