Is there a problem about revising Logic?
How, if at all, can one rationally change which logic one employs? I'll reply both to those who think we can't and to those who minimize the problems of doing so, and suggest a model for how such rational change might occur. I'll connect the discussion with a real example: the issues surrounding what I take to be a serious though not incontrovertible case for logical revision.
