SUMMARY:The Logic of Polyreference
DESCRIPTION:In previous work\, I have defended anovel view of the semantic 
 of proper names\, i.e.\, the PolyreferentialView. According to this view\,
  proper names can have more than onesemantic referent\, indeed as many as 
 bearers of the name there are.However\, the view still sees proper names a
 s referential terms thatcontribute their referents to the propositional co
 ntent. This has theimplication that a sentence containing a polyreferentia
 l name wouldthereby express many propositions or contents\, as many as ref
 erentsfor the name there are. This paper proposes a logic for this newsema
 ntic relation of polyreference and gives an account of compositionality.&n
 bsp\;Given a standard way of understandingsentence truth as depending on t
 he truth of the proposition itexpresses\, we have that for any sentence S\
 , S is true when it expresses a true proposition and S is false when it ex
 presses a false proposition. So\, most sentencescontaining polyreferential
  terms will be true\, and they will befalse. As a result\, we won&rsquo\;t
  be able to reason from the truth orfalsity of sentences in the standard w
 ay &ndash\; e.g. `David is happy andDavid is not happy&#39\; expresses man
 y different propositions\, only someof which are contradictions\, for many
  others are true propositions\,e.g.\, when Hume is happy and Lewis is not 
 (among many otherpossibilities). Although in this framework\, some standar
 d reasoningswould not be valid\, the paper argues that this is not necessa
 rily abad result. I suggest that when taking the fact that names havemulti
 ple bearers seriously\, our intuitions about the truth andfalsity of sente
 nces\, and of the validity of inferences may change.The logic proposed\, h
 owever\, can cope with most of our ordinary reasonings with proper names.
