The problem I always have in taking 'polylogism' seriously is when I wonder
what logic is supposed to be used when several topics are mixed together,
and to decide among the various different logics. Suppose Arthur and I are
discussing, say, the square root of the number of working-class Nazis that
would be suitable for a crowd scene in a movie, what logic do we use? And
suppose we discover (never mind how) that we are using different logics,
how can we resolve our differences?
