Fair enough, I missed the mark that I was intending. Possibly he remains better recognized in Germany than in North America; and it’s admittedly not my field. At the same time, more than once when I’ve posed the question about the utility of ZK, I’ve been pointed only to Luhmann. His academic productivity isn’t in dispute. And seemingly, for him, it was aided by the methodology that is promoted by ZK followers now. But it’s also an n=1 data point. I wonder if the ZK community has identified other productive and impactful academics who are devotees.
As for the last comment: having gone to medical school some decades ago and trained in cardiology, I’m familiar with Virchow. I would be surprised to encounter any physician who hadn’t any familiarity with him. But who knows?!
