Briefly, Truth is an idea of a supra-rational order, pertaining to Neschamah, not to Ruach. That all rational conceptions imply that we know Truth, and that Truth is in their propositions, only shows that these so-called rational ideas are not really rational at all. Truth is by no means the only idea that resists rational analysis. There are very many ideas that remain indefinable: all simple ideas do so. At the back of all our efforts is the dead wall that we must already know what we are pretending to find out.
