If we know that there's a burglar, then we think that either an alarm or a recession caused it; and if we're told that there's an alarm, we'd conclude it was less likely that there was a recession, since the recession had been explained away.

Should that be "since the burglar had been explained away"? Or am I confused?

Edit: I was confused. The burglar was explained; the recession was explained away.

If people weren't around, then "snow is white" would still be a true sentence, but it wouldn't be physically embodied anywhere (in quoted form). If we want to depict the quoted sentence, the easiest way to do that is to depict its physical embodiment.

Beliefs should pay rent, check. Arguments about truth are not just a matter of asserting privilege, check. And yet... when we do have floating beliefs, then our arguments about truth are largely a matter of asserting privilege. I missed that connection at first.
