I have a buddy who is a communications professor. He speaks the Gramsci/Foucalt lit crit hegemony stuff all the time. Mostly, I haven't got the first goddammed idea what he's talking about, though I have given it enough of a try to encounter the Sokhal hoax and stuff like that. But once, he asked me what it would take to 'overthrow' the periodic table. I tried to make the point that, fundamentally, the periodic table is an organization of experimental observation, that has since been backed up with theory. He wondered why we 'privilege' this particular structure.
After trying really hard to understand what the hell he meant, I got the impression that he thinks, honestly, that scientists just make shit up and all agree to discuss it in a certain way. I basically told him that he had the luxury of this because he didn't interact with things that would mercilessly render him dead as a rock if didn't privilege the knowledge that has been gained over time, different ways of knowing be damned.
He thought, and then said, "Yeah, if I write down something that doesn't conform to the narrative of my field, my papers won't explode." I think that we may have understood one another for a few minutes, at least.
And to safety-critical engineers, if we don't get things right, then people really will die, or be blinded, or maimed, as the result.
Perhaps it would be useful for some Lit Crit people to deconstruct this fragment from Kipling:
Then the Gods of the Market tumbled, and their smooth-tongued wizards withdrew
And the hearts of the meanest were humbled and began to believe it was true
That All is not Gold that Glitters, and Two and Two make Four
And the Gods of the Copybook Headings limped up to explain it once more.
And meanwhile I find myself explaining for the (n+1)th time about autopsy results and brain-scans, arguing that HBS is neither cured by Exorcism, nor Spirit Release Therapy. And trying to counteract anonymous articles in the California Catholic Daily such as No Crossdresser Left Behind.
