Review of The Meaning of `Ought` by Matthew Chrisman Billy
... semantics as he claims that it needs non-trivial modification. His central motivation stems from the distinction between the so-called “agential” and “non-agential” readings of sentences containing ‘ought’. To use Chrisman’s example, we might truly say “Larry ought to win the lottery”, in a context ...

... (2009). The basic semantic concept is that of a (finite, single-agent) ‘‘plausibility’’ frame. This is a structure S = (S, B), consisting of a finite set S of ‘‘states’’ (or possible worlds) and a total preorder S S.1 We use the notation s \ t for the corresponding strict order (i.e. s \ t iff ...

... Solution: A logic is non-monotonic if an answer that was obtained from a knowledge base continues to be true after adding more knowledge. In the case of FOLprogramming this is not the case as the following example shows. Consider a logic program with a single fact: P (a). The answer to the query ← P ...

When Bi-Interpretability Implies Synonymy
... Here ‘=da ’ is not really in the language if d 6= a. In this case we read ud =da y b simply as ⊥. It’s a nice exercise to show that e.g. ACA0 and GB are sequential. Closely related to AS is adjunctive class theory ac. We define this theory as follows. The theory ac is two-sorted with sorts o (of obj ...
