Steve Patterson: Certainty and Logic | WSB #26

February 6, 2018

Steve Patterson's book Square One: The Foundations of Knowledge begins with the bold claim: "Truth is discoverable. I'm certain of it." The rest of the book is an attempt to prove that there are certain truths for which there is not a sliver of doubt.

I am, to say the least, unconvinced. Universal fallibilism - the claim that all knowledge leaves room for doubt - is, ironically enough, a view I'm particularly confident of (though, obviously, not certain of). Indeed, I did a two-part podcast on this topic (Against Certainty: Knowledge and Experience and Against Certainty: Logic). In this interview, I challenge Steve's claims to certainty with my skeptical doubts. The conversation takes us through the Münhhausen Trilemma, the nature of justification, subjective experience, and, of course, the ever-popular liar paradox.
