Quantity implicatures

Assorted worries about Horn scales/setsHorn scales/sets may be viewed as way of dodging theproblem of relevance. Basically, this problem is stipulatedout of existence.What are Horn scales/sets, and where do they come from?The Horn-style analysis of scalar implicatures suggests thata generative theory of Q-implicatures is possible. However,such a theory will not work for other Q-implicatures:E.g.: Bonnie stole the apples or the pears. ¬Bel S (Bonnie stole the apples) ¬Bel S (Bonnie stole the pears)Finally:What does this have to do with conversational implicature?Quantity implicatures
