It's almost like this:
"Anything but grasping the conch. Any moment other than the obvious one at which humans started burning loads of fossil fuels!"
There's some kind of weird Oedipal logic to this. Like no one wants to say the big bad obvious thing.
Like we quite happily say "capitalism" and we quite happily say when it started. Despite the very accurate Braudelian shading of that concept and that start date. Like we admit there's loads of capitalisms, then there's big bad official capitalism, "since 1784" as they say below certain store names. (Marx says the steam engine, etc. Word.)
And there are terms for saying it started earlier or never started. Such as Whiggish history.
Just for a mo I thought we were all about to get seriously into working with science and scientists. But somehow the old school managed to get its correlationist paws on stuff and it's back to endlessly fuzzing and namechecking concepts and people (and not lifeforms) before we say anything at all, which we'd rather not. Heaven forbid we do our job. Better to talk amongst ourselves. Safer. My mistake...
