Foucault's Errantcy

I was kind of struck with this notion of error, aberrant, errantcy. And so this figure of error in Foucault sort of struck me. When you read his work on George Kungi-Lan, who wrote his seminal text in the 40s and wouldn't be published into English until I think the 80s. What Foucault finds is that in Kungilim's engagement with the history of science is life is no longer something that that has to be engaged with at these moments of medical crisis.
