It is an unfortunate fact that the bulk of humanity is too limited in its mental vision to weigh with patience and intelligence those isolated phenomena, seen and felt only by a psychologically sensitive few, which lie outside its common experience. Men of broader intellect know that there is no sharp distinction betwixt the real and the unreal; that all things appear as they do only by virtue of the delicate individual physical and mental media through which we are made
conscious of them; but the prosaic materialism of the majority condemns as madness the flashes of supersight which penetrate the common veil of obvious empiricism.
