%X we show the traditional doctrine of simple conversion of categorical and modal quantified sentences. we do this by resorting to the medieval analysis of sentences by means of identity sentences which result necessary when they are true and impossible when when they are false. to simplify we reduce our universe of discourse to small £¿worlds£¿ of individuals and properties; we use standard symbols but add a new one for the modal treatment.
