Related to my observation that the positions of liberals and conservatives have changed over time, I ran across this Thomas Pynchon essay from 1984. It wanders - not the level of clarity one expects from the NYT Review - and several things Pynchon states emphatically turned out to be not so. Interesting for what it is, a period piece, reflecting how NYT readers thought at the time.
I had commented on CP Snow's Two Cultures before. Of most interest for quick thought is Snow's later modification that it was now Three Cultures, as the social sciences occupied a range not necessarily knowledgeable about either science nor art and literature.
