Meditation leads from ignorance to ignorance, from ignorance which does not know itself to ignorance which does know itself. This is the point that philosophers attain to. Also, true philosophy is to laugh at philosophy; and if Aristotle and Plato deserve the name of philosophers, it is rather by the practical wisdom of their life than by their metaphysical speculations. Reason alone, then, is an imperfect or a false instrument; and if truth is to enter into us, it is by another door than that of reasoning.
