Our view was never that truth is just a question of which perspective you see it from.
Bruno [Latour] and I were at a conference together in Brazil once. (Which reminds me: if people want to criticize us, it ought to be for the amount of jet fuel involved in making and spreading these ideas! Not for leading the way to post-truth.)
Anyhow. We were at this conference. It was a bunch of primate field biologists, plus me and Bruno. And Stephen Glickman, a really cool biologist, took us apart privately. He said: “Now, I don’t want to embarrass you. But do you believe in reality?”
We were both kind of shocked by the question. First, we were shocked that it was a question of belief, which is a Protestant question. A confessional question. The idea that reality is a question of belief is a barely secularized legacy of the religious wars. In fact, reality is a matter of worlding and inhabiting. It is a matter of testing the holdingness of things. Do things hold or not?
Take evolution. The notion that you would or would not “believe” in evolution already gives away the game. If you say, “Of course I believe in evolution,” you have lost, because you have entered the semiotics of representationalism – and post-truth, frankly. You have entered an arena where these are all just matters of internal conviction and have nothing to do with the world. You have left the domain of worlding.
