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 abando… - Richard Rorty

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.

… our maturation has consisted in the gradual realization that, if we can rely on one another, we need not rely on anything else. In religious terms, this is the Feuerbachian thesis that God is just a projection of the best, and sometimes the worst, of humanity. In philosophical terms, it is the thesis that anything that talk of objectivity can do to make our practices intelligible can be done equally well by talk of intersubjectivity.

As long as we try to project from the relative and conditioned to the absolute and unconditioned, we shall keep the pendulum swinging between dogmatism and skepticism. The only way to stop this increasingly tiresome pendulum swing is to change our conception of what philosophy is good for. But that is not something which will be accomplished by a few neat arguments. It will be accomplished, if it ever is, by a long, slow process of cultural change – that is to say, of change in common sense, changes in the intuitions available for being pumped up by philosophical arguments.
