Citizens of a Jeffersonian democracy can be as religious or irreligious as they please as long as they are not “fanatical.” That is, they must abandon or modify opinion on matters of ultimate importance, the opinions that may hitherto have given sense and point to their lives, if these opinions entail public actions that cannot be justified to most of their fellow citizens.

Rather, we heirs of Enlightenment think of enemies of liberal democracy like Nietzsche or Loyola as, to use Rawls’s word, “mad.” We do so because there is no way to see them as fellow citizens of our constitutional democracy, people whose life plans might, given ingenuity and good will, be fitted in with those of other citizens. They are crazy because the limits of sanity are set by what we can take seriously. This, in turn, is determined by our upbringing, our historical situation.

Contemporary intellectuals have given up the Enlightenment assumption that religion, myth, and tradition can be opposed to something ahistorical, something common to all human beings qua human.
