This is Richard Marshall's interview with Zach Weber, an expert in philosophical logic, with a focus on paradoxes and non-classical logic. It is intended, and to a degree succeeds, to challenge the reader's preconceptions about logic and especially truth. There's a lot going on in this article. Part of it leverages the ambiguity of simple and very formalized propositional logic (for example: "either P implies Q, or Q implies R"), but most of it is targeted directly at the tension of truth as describing the state of affairs in the world (a.k.a. Tarski semantics) and truth as a feeling (for example, when "claims have some intuitive pull for being true". Sitting right in the middle of all that is 'true in a Model'. If you're wondering where I stand in all that (and who doesn't?) well, the way I see it, if I say 'P is true', this is a statement about me, and specifically, my attitude about P (and the same if I say 'P is true in M').
