They are so far off, I shall not attempt to prove Spiritualism by rapping for some time yet. People say we have got beyond the rapping. The truth is, a large portion of the world have not yet got to the raps. They are not yet able to appreciate the raps. We must make considerable progress before we can get the philosophy of the raps. We have much to learn yet before we can get the full benefit of a simple sound, even though it be not accompanied by much intelligence. The first lesson I shall attempt to teach—pardon me for assuming to be a teacher, I will be a pupil at any time—is how to study and know yourselves; how to ascertain the laws of your being, action, and manifestation; how to determine what is and what is not spiritual in you; how to determine whether you are under Spirit-influence or not—for there are laws by which all these things can be determined. In my investigation I shall perhaps be able to determine where that terrible creature, Jack, the Giant-killer, the Odylic force, resides, and show what it can and what it can not do. And I promise, too, in the face and eyes of all theorizers who believe that the Spiritual manifestations are traceable to this force, and to the satisfaction of everybody else, to demonstrate that it is not competent to produce them. I will demonstrate it according to President Mahan’s hypothesis. I will show by every known law of nature that the power exerted at the brain’s center, in a single instance he has given, was equal to a thousand steam-engines of a million horse-power at the distance of five feet from the brain. But that will merely come in as collateral when I consider the objections offered to our theory. I will endeavor to consider every objection which any objector has proposed to bring forward. I do not stand here to boast, but what I speak is to me absolute. I stand here fearlessly, and invite all classes of minds to raise any objection they can to the Spiritual theory; and I bind myself to answer them instanter, or confess my inability to do so. The invitation commences now, and extends to every moment I am in the city. In my next lecture I shall begin with the question of Spirit-spheres, and endeavor to unfold to the consciousness of each of you the evidence of the existence of a first sphere, from which you will all do well to escape; and shall then proceed to prove the existence of other spheres, namely, the second, or relational sphere, and a third, or divine sphere. I invite skeptics and atheists in particular to be particularly captious. CHAPTER II. THE SPHERE OF LUST.
