Making it Exact
摘要
Bob and Ulf say logic should make explicit. The kinds of inference we take as licit. They give a formalism that’s classically complete, In which an extra premise may defeat. An inference that seems a reasonable fact. Thus reason’s made explicit but is it exact? For reason in the sense of Brandom and Hlobil, May explode like a logical Chernobyl. This is the point on which I’ll here push back, To keep the game of giving reasons exact; And with the help of fancy formal antics, I’ll give nonmonotonic truthmaker semantics.
