The Relevant Alternative Theory of Knowledge
Posted in Epistemology, Logic on October 14, 2009 | 12 Comments »
[ADMINISTRATIVE NOTE: MOVING TO THE FRONT (FROM AUGUST 15)]
Epistemic agents claim to know that-P within a context of competing alternative propositions, {A1, A2… An}, all of which would be as equally consistent with the facts as P, but necessarily exclude P, such that:
If some one member of {A1, A2… An} were true, then that-P would [...]
Video Lecture: Introduction to Modal Logic by Rajeev Gore

Rajeev Goré of Australia National University gives a very approachable introduction to propositional modal logic in this video lecture here. It’s a nice, non-technical exposition of the relationship of syntax, semantics and derivation calculus for modal logic. Particularly interesting (and convincing!) is Goré’s assertion that Kripke frames can be intuitively understood in terms of graph [...]

An infinity of undecidable sentences — Yablo’s Paradox, formal systems and incompleteness
Posted in Logic, Philosophy of Mathematics on February 14, 2007 | 4 Comments »
Most who are familiar with any sort of basic incompleteness result (like Gödel’s First Incompleteness Theorem) for formal systems are acquainted with a proof of the theorem which precisely states the result that demonstrates a single sentence of the language of the system that is neither provable nor whose negation is provable – that is [...]
