Quoting that entry: "Sokal said he was inspired to submit the bogus article after reading Higher Superstition (1994), in which authors Paul R. Gross and Norman Levitt claim that some humanities journals will publish anything as long as it has "the proper leftist thought" and quoted (or was written by) well-known leftist thinkers."
"ALAN SOKAL: In the spring of 1994, I saw a reference to the book by Paul Gross and Norman Levitt, Higher Superstition: The Academic Left and Its Quarrels With Science. My first thought was, Oh, no, not another one of those right-wing diatribes that tell how the Marxist deconstructionist professors are taking over the universities and brainwashing our children. There had been a whole spate of such books in the early 1990s — Dinesh D’Souza and others.
"My second thought was "academic left and its quarrels with science"? I mean, that’s a little weird. I’m an academic leftist. So I decided to read it. I learned about a corner of the academy where people were employing either deconstructionist literary theory or extreme social constructivist sociology of science to make comments about both the content of science and the philosophy of science, often in gross ignorance of the science. The first thing I wanted to do was go to the library and check out the original works that Gross and Levitt were criticizing to see whether they were being fair. I found that in about 80 percent of the cases, in my judgment, they were."
...
"I thought, well, I could write an article to add to the Gross and Levitt critique, and it would probably disappear into a black hole. So I had the idea of writing an article that would be both a parody and an admittedly uncontrolled experiment: I would submit the article to a trendy journal and see whether it would be accepted."
...
"BARBARA EPSTEIN, professor emerita, history of consciousness department at the University of California at Santa Cruz: A friend of mine at UC-Davis said that she wanted to tell me about something if I would promise absolute secrecy. She said there is a physicist at NYU who has written an article that purports to be by a scientist who has converted to poststructuralism, and actually, it’s a hoax.
"She said he wants to find a humanist who knows something about poststructuralism, can’t stand it, is a leftist and feminist, to work with. He wanted to write a piece outing himself, and explaining why he had done it. I said, "Absolutely. Sign me up.""
...
"EPSTEIN: ...By that time [after the article was published, but before Sokal's second article exposing the hoax], I really was persona non grata. It was very clear that I was a minority in my department, and not only a minority but a target. I had an article in Socialist Review in which I criticized poststructuralism. It had become a crusade and an orthodoxy and a juggernaut, and the more I was part of that culture, the more I disliked it. The emotional atmosphere around this wasn’t that different than the emotional atmosphere around the election right now. People on two sides of the fence were barely talking to each other."
After reading Rawls, I'd suggest maybe reading Robert Nozick's libertarian leaning Anarchy, State, and Utopia. Nozick was another distinguished philosopher from Harvard writing about the same time as Rawls. Nozick comes to a completely different conclusion than Rawls.
Both books are good and completely accessible to an ordinary reader (i.e. philosophy degree not required). However, they are serious and not as entertaining as the Friedmans' Free to Choose. While the two philosophy books address the question of what should a fair society look like from a philosophical perspective, I feel they don't address the aspects of human nature that have proven troublesome in socialist economies as well as Free to Choose.
Finally another classic, The Fatal Conceit by F. A. Hayek considers the practicality of socialism from an economic position in a more focused way. Like the previously mentioned books, it is an easy read.
These books may not reflect cutting edge thought, having been written in the 70's and 80's, but they were a useful starting point for me when I started to think about these issues more deeply and they are considered seminal works that in my opinion shouldn't be skipped while studying the questions of political and economic theory.
A Conflict of Visions by Thomas Sowell further reflects on this question and makes some conclusions about why smart people end up disagreeing in such fundamental ways. I find Sowell's thinking and writing to be clear and well expressed.
Finally, an interesting book addresses the puzzling and related question of why does the academic community so easily accommodate views so antithetical to a scientific world view. I believe that this at the heart of the questions raised by the original NYT piece. The book is Higher Superstition by Gross and Levitt. While interesting this book is erudite and seems directed to narrower audience than those mentioned above, expecting a well-read reader.
