QUÆRENS. Certainly, master, I own that as you unfold these possibilities a new and singular clearness enlightens my understanding, and your teachings appear to me a true interpretation of the reality. I had already dreamed that similar marvels might be possible, but I had not been able to explain them, enveloped as I still am in my terrestrial senses. One thing is certain, we must be lifted out of our earth-bound limitations ere we are capable of comprehending, or even of attempting to judge, of the scope of the universe. Thus, being endowed with only a few limited senses, we can but know the facts that are perceptible to them. The remainder is naturally unknown. Can it be that the unknown is infinitely more than the known? [Sidenote: The ordinary senses are insensible to many physical movements.] LUMEN. This "remainder" is immense, and all you at present know will seem as nothing by comparison. Not only do your senses not perceive physical movements--such as solar and terrestrial electricity whose currents cross in the atmosphere, the magnetism of minerals, of plants, and of beings, the affinities of organisms, &c., which are invisible to you--but they perceive still less the movements of the moral world, its sympathies and antipathies, its presentiments, its spiritual attractions, &c. I only speak the simple truth when I say, that all that you know, and all that you could know, through the medium of your earthly senses, is as nothing compared to that which is. [Sidenote: Beings exist with other than our senses.] This truth is so profound that it might well be asserted, that beings exist upon the Earth essentially different from you, possessing neither eyes, nor ears, nor any of your senses, but endowed with _other_ senses, and capable of perceiving that which you cannot perceive, and who, while living in the same world as yourself, know that which you cannot know, and form an idea of nature completely at variance with your own. QUÆRENS. All this is utterly beyond my comprehension. LUMEN. Moreover, my earthly friend, I can add most emphatically that the perceptions you receive, and that constitute the bases of your science, are not even the perceptions of the _reality_. No. Light, lucidity, colours, looks, tones, noises, harmonies, sounds, perfumes, flavours, apparent qualities of bodies, &c., are nothing but _forms_. These forms enter into your mind by the avenue of the eye, and the ear, by the senses of smell, and taste, and are represented to you by their appearances, but not even by the essence of the things themselves. _The real nature of things entirely escapes your understanding, and you are utterly incapable of comprehending the universe._ [Sidenote: Matter is not solid.]
