"All rationalistic philosophies end, and, inevitably end, in agnosticism. This is the one logical conclusion to the search for knowledge in that way by that instrument.. having been inspired and set in motion by intuition ... the rationalistic philosopher instantly turns his back upon intuition... Having begun with intuition, he should go on with intuition." Charles Johnston comm. on Kena Upanishad. As the Katha Upanishad expressed it, " Nor is this mind to be gained by reasoning;.... it is to be apprehended by .... direct experience."
