John Derbyshire has some thoughts about the latest attempt to defy human nature and biological determinism:
…remember that the human sciences differ from the physical sciences in an important way. We have been acquainted with galaxies, quarks, genes, superconductors, neurons, and tectonic plates for only a few decades. We have been observing each other — our fellow human beings — with very keen interest for several dozen millennia, since homo sap first showed up and formed social groups. We should therefore expect far fewer surprises in the human sciences than in the physical sciences. The reasonable expectation is, that the human sciences mostly just validate and quantify what we always kinda knew. Striking, dazzlingly counter-inutitive results show up a lot in the physical sciences. In the human sciences they ought to be rare. When such results are announced, they should be approached with even more than the scientifically-normal amount of skepticism.
Both social conservatives and the left have a huge ideological investment in the tabula rasa theory of humans. Social conservatives because it is necessary for them to believe that homosexuals are made, not born, and leftists because they always seek to remold man in the image of their utopia, to fit him in their procrustean bed of equality and “fairness.”
