As with all human attempts to categorize things, the 4 categories should actually be a spectrum, and the ends of the spectrum should be called into question based on PG's definition here. I mostly agree. I think I probably fall on the more "independent-minded" end of the spectrum (as we all like to think). But there is value in conformism and value in independence of thought. PG should realize the fact that he wrote this essay and is still alive is a good example of where things are today vs. in the era of feudalism or even the era of WW2 :)

I agree with his take on academia though. That whole institution is limping along.
