Massimo Pigliucci is a self-styled public intellectual who runs a blog misleadingly called Rationally Speaking. It is in fact highly politicized, a vehicle for Professor Pigliucci to promote his left-liberal views – and himself. Which (apart from the misleading blog name) would be fine, if it wasn't for the site's (and Massimo's) loyal followers, and the feeling that one is dealing here not with a group of freely thinking individuals but with a sort of cult. [Update Nov. 2013: Whether or not this was true at the time, I have to say that this is no longer how I see the site. For one thing, one of the secondary writers there who was very political has gone, and my sense is that Massimo himself (with whom I have had some productive interactions) has focused more on non-political topics in the last couple of years. Also, there is much robust debate in the comment threads, and a variety of views on display.]
So I had a sense of Schadenfreude (unworthy, I know) when I read this post by Pigliucci on an imminent restructuring of the curricula at the City University of New York where he is employed as a philosophy professor.
The proposal incorporates a reduction of the compulsory general education requirements from more than 50 to 30 credits (out of a total of 120 credits necessary for graduation). And within that 30 there is a 'required core' of 7 credits in English composition and 8 in mathematics and science. Professor Pigliucci alleges that this is part of a national trend towards "dismantling liberal arts education" and that these efforts are motivated by an attempt to produce not "intelligent and critically thinking citizens" but "workers who are trained to do whatever the market and the reigning plutocracy bids them to do." Unfortunately, the phrase "reigning plutocracy" gives him away.
It's my view that many - too many - academics in the humanities have betrayed their calling by allowing the content of what they teach to become politicized to an extreme degree. Too often divergent views on controversial issues are not welcomed and students are required to echo the politically correct clichés of their teachers in order to succeed. Feminism, multiculturalism, standard liberal views on social issues, geo-politics and capitalism dominate teaching and writing in many areas within the humanities and social sciences. And so the process continues, as indoctrinated college graduates become teachers themselves or journalists or public employees of one kind or another or occupiers of Wall Street.
So I'll not be shedding any tears for Massimo and his like if they lose their battle to maintain their power and influence. All in all, I think some good may come from the withdrawal of funding from the humanities as certain particularly noxious forms of indoctrination will be curtailed.
And whatever there is of abiding value in the areas affected by funding cuts will more than likely be incorporated - under other names perhaps - into new curricula, or find other modes of survival.

Sense and self-indulgent nonsense
I recently referred - perhaps unfairly - to the propensity of many mathematicians and scientists to be naive and uncritical when thinking outside their areas of expertise. Of course, we are all inclined to be naive and uncritical at times, but the phenomenon is more striking in a person who exhibits high levels of critical thinking in a specialist area. My original observation was based in part on having read a lot of autobiographical and other material written by very gifted scientists and mathematicians and wondering why I found myself having to 'make allowances' for them.
The distinguished mathematician Gregory Chaitin is a case in point. Here are a few instances of the strange mix of sense and nonsense that flows from Chaitin's pen when he moves beyond the work which has made him famous. [All the quotations are from his book Meta Math! The quest for omega*.]
On medical care. "[I]n my grandmother's generation in the old country, women would have a dozen children, most of whom would die before puberty. So you were trying a dozen mixes of DNA subroutines from both parents. (In the Middle Ages, babies weren't even named til they were a year old, since so many of them would die the first year.) Now instead of trying to keep women pregnant all the time, we depend on massive amounts of medical care to keep alive one or two children, no matter how unhealthy they are. While such medical care is wonderful for the individual, the quality of the human gene pool inevitably deteriorates to match the amount of medical care that is available. The more medical care there is, the sicker people become! The massive amounts of medical care become part of the ecology, and people come to depend on it to survive ... "
On mathematical prehistory. "[F]undamental questions go back millennia and are never resolved. For example, the tension between the continuous and the discrete, or the tension between the world of ideas (math!) and the real world (physics, biology). You can find all this discussed in ancient Greece. And I suspect we could even trace it back to ancient Sumer, if more remained of Sumerian math than the scrap paper jottings on clay tablets that are all we have, jottings that give hints of surprisingly sophisticated methods and a love for calculation that seems to far outstrip any practical application."
Chaitin cannot resist a footnote: "Did Sumer inherit its mathematics from an even older civilization - one more advanced than the ancient Greeks - that was destroyed by the glaciers, or when the glaciers suddenly melted, or by some other natural catastrophe? There is no way for such sophisticated computational techniques to appear out of nowhere, without antecedents."
On ideas and creativity. "Let me describe what it feels like right now while I'm writing this book ... [T]he ideas I'm discussing seem very concrete, real and tangible to me. Sometimes they even feel more real than the people around me. They certainly feel more real than newspapers, shopping malls and TV programs ... In fact, I only really feel alive when I'm working on a new idea, when I'm making love to a woman (which is also working on a new idea, the child we might conceive), or when I'm going up a mountain! It's intense, very intense."
Chaitin elaborates and reiterates with references to beautiful women, art and food (" ... like an amazing ethnic cuisine I've never tasted before."). He continues:
"And I'm a great believer in the subconscious, in sleeping on it, in going to bed at 3 a.m. or 5 a.m. after working all night, and then getting up the next morning full of new ideas, ideas that come to you in waves while you're taking a bath, or having coffee. Or swimming laps. So mornings are very important to me, and I prefer to spend them at home. Routine typing and e-mail, I do in my office, not at home. And when I get too tired to stay in the office, then I print out the final version of the chapter I'm working on, bring it home - where there is no computer - and lie in bed for hours reading it, thinking about it, making corrections, adding stuff.
"Sometimes the best time is lying in bed in the dark with my eyes closed, in a half dreamy, half awake state that seems to make it easier for new ideas, or new combinations of ideas, to emerge. I think of the subconscious as a chemical soup that's constantly making new combinations, and interesting combinations of ideas stick together, and eventually percolate up into full consciousness. That's not too different from a biological population in which individuals ... combine to produce new individuals. My guess is that all this activity takes place at the molecular level - like DNA and information storage in the immune system - not at the cellular level. That's why the brain is so powerful, because that's where the real information processing is, at the molecular level. The cellular level, that's just the front end ...
"Yes, I believe in ideas, in the power of imagination and new ideas. And I don't believe in money or in majority views or the consensus. Even if all you are interested in is money, I think that new ideas are vital in the long run, which is why a commercial enterprise like IBM has a Research Division and has supported my work for so long. Thank you, IBM!"
It takes your breath away, does it not?
