Can a belief be subjunctively rational? (Such a belief would be found to be rational were we fully to investigate it.) If it can't be, the only rational people would be utterly pathological, incapable of the smallest act without decades of research. If it can, rationality becomes primarily a question of appropriate trust; the mark of the rational is the existence of well-placed faith in others. But even if our trust is well-placed, is it more rational to hold a rational belief for irrational reasons or to trust the rationality of another who may turn out to have made serious errors? The latter seems more of a basis for community, but in life-or-death situations facts care nothing for their derivation.
