I have spent so many years of arduous labor on these investigations, and have become so thoroughly convinced of their truth, that I have ventured to make these assertions without the slightest compunction, or fear of final contradiction. Although the facts involved in these matters entitle me to these declarations, I would not have overstepped the bounds of modesty in so far as to make them had not my first experience forced upon me the conviction that the path of modesty in matters of this kind is not the one to success. I was so impressed with the exalted position of science, and so apprehensive of my own powers, that in my former publication I as much as apologized for my temerity in telling the scientific world things of which it did not have any previous knowledge. These last four years, however, have so enlarged my views and given me such a firm grasp and insight, that I no longer fear any man's judgment. I would, on the contrary, heartily welcome honest and competent criticism, being convinced that the same would not and could not but strengthen my position. As a matter of personal gratification, I am indifferent to success; but I think the time has come when these matters should not continue to remain with me alone, but should become the property of all, not for my sake, nor simply for that of science, but for the sake of truth, and the benefit of mankind. Had my previous statements been given the consideration they deserved, other persons, in all probability, would have made _some_ of the many discoveries, at least, that it has now been my privilege to make single-handed. Still, the field is inexhaustible; that which I have discovered being but an index hand to that which is still to be discovered. Having no reason to doubt but that I am a properly organized member of the human family, I consider myself entitled to speak of my personal experience as in like manner applicable to every other member of that family. Having found it expedient to frequently address the reader in a "direct" manner, using the personal pronoun "you" in so doing, I must ask his pardon for this liberty. In thus addressing him, I trust we shall be in better rapport; all I shall have to say thus becoming, in a manner, a confession as from author to reader. While I confide in him and make him participate in these vital discoveries, I want him to confide in me, in so far as to take it for granted that all I shall say is truthfully meant, and that it has been arrived at, not superficially, but only after the most searching and long-continued investigations. We will thus become partners in a research as great as any that has ever agitated man's mind, or filled his soul with things of great moment. Having penetrated into matters which have heretofore been considered as occult, or inaccessible to man, my mode of proceeding will be found interesting as a guide to others wanting to pursue similar investigations.
