Thanks to everyone who suggested all kinds of good things for me to look at regarding this issue.
It's terribly helpful, actually, as I've been wondering what kind of datasets and argument resources I can draw on for Dark Ecology, and this is quite intuitively one of them, but one that I hadn't been paying attention to since I hung out with Mick Taussig in the early nineties.
Tim Ingold has been on my radar since we met in Geneva a few years ago. I loved his talk but we got a bit shirty with each other in the roundtable. Never mind, I think we dig each other now.
So again, a heartfelt thank you.
