THE PARADOXES OF STRICT IMPLICATION John L
... implication with a relation between meanings. However, we must be more explicit about just what this relation is. Let us begin with the case of analytic equivalence. It is probably the predominant view that the statement that p (e.g., the statement that 2 + 2 = 4) and the statement that q are analyt ...

Acts of Commanding and Changing Obligations
... A word about my choice of monadic deontic operators here may be in order. Monadic deontic logics are known to be inadequate to deal with conditional obligations and R. M. Chisholm’s contrary-to-duty paradox; dyadic deontic logics are better in this respect. But there are still other problems which a ...

Inference in FOL Last Lecture

If necessary, attempt to prove the implication also via backward chaining premises that are conjuncts are processed one co ...

Combining Paraconsistent Logic with Argumentation
... but plausible argument orderings are possible in which C 6≺ D2 and so C defeats D2 . This is problematic, since s can be any formula, so any defeasible argument unrelated to A2 or B2 , such as D2 , can, depending on the argument ordering, be defeated by C. Clearly, this is extremely harmful, since t ...
