Conscience and the Common Good?

I have posted here (and at the right) a comment (delivered at a conference last November at Notre Dame) on our very own Rob Vischer's provocative new book Conscience and the Common Good.  The comment will be published in the Journal of Catholic Legal studies (along with comments by Michael Moreland and Nora O'Callaghan).  Rob has done us a great favor by advancing the discussion of several crucial concepts, which is not to say that I agree with all Rob has to say in the book.  For example, I fear that on Rob's account the Church has sub silentio become something like a Roman variation on the Boy Scouts.
