Joel and Travis talk Wittgenstein's Tractatus, propositions 3 and 4. Joel says stuff about what can be said and what can only be shown, how this relates to not saying what cannot be said, and says showing a sad shed should sell said shed's shady sheerness . Well, he doesn't talk about that last bit, but he does try to explain Wittgenstein's thoughts on stuff like the say-show distinction, and related matters, which is almost as interesting as silly tongue twisters.
