Faith is, at best, a cease-fire. It is a bridge of assumptions, of holding actions to fix the battle in place, while other matters bear attention. Religious faith is often scorned; but if dogma is held in place by the will of others, it is confinement.
Without faith lies only Hume’s skepticism, the good side of logical positivism. But we have embraced a post-rational logic. If there is no reality that is provable, then any dogma can suffice.
