Twenty years ago Macvicar wrote his "Sketch of a Philosophy," in which he advanced the above views, with other views now maintained and demonstrated by Keely, who during these twenty years, without knowing Macvicar's views, or of his existence even, has been engaged in that "dead-work which cannot be delegated," the result of which is not learning, but knowledge; for learning, says Lessing, is only our knowledge of the experience of others; knowledge is our own. This burden of dead-work, writes Lesley, every great discoverer has had to carry for years and years, unknown to the world at large, before the world was electrified by his appearance as its genius. Without it, there can be no discovery of what is rightly called a scientific truth. Every advancement in science comes from this "dead-work," and creates, of its own nature, an improvement in the condition of the race; putting, as it does, the multitudes of human society on a fairer and friendlier footing with one another. And during these twenty years of "dead-work" the discoverer of etheric force has pursued the even tenor of his way, under circumstances which show him to be a giant in intellectual greatness, insensible to paltry, hostile criticism, patient under opposition, dead to all temptations of self-interest, calmly superior to the misjudgments of the short-sighted and ignoble; noble means as indispensable to him as noble ends; fame and riches less important than his honour; his joys arising from the accomplishment of his work and the love and the sympathy of the few who have comprehended him! "Only the noble-hearted can understand the noble-hearted." Keely's chief ambition has been to utilize the force he discovered; not for his own aggrandizement, but to bless the lives of his fellow-men. He has scaled the rocks which barricade earth from heaven, and he knows that the fire which he has brought down with him is divine. This so-called secret is an open secret, which, after it is known, may be read everywhere,--in the revolution of the planets as well as in the crystallization of minerals and in the growth of a flower.
