William James, a scientist of real authority, has a wonderful essay, "The Powers of Men," in which he sets forth the fact that human beings as a general rule make use of only a small portion of the energies which dwell in their beings, and that one of our problems is to find the ways by which we can draw upon stores of hidden energy which we have within us. Also, in a fascinating book, "Varieties of the Religious Experience," James has endeavored to study and analyze the phenomena which hitherto the physician and the biologist have been disposed to ridicule and neglect. But unless I am mistaken, every scientist in the end will be forced to come back to the central fact, that life is a unity, and that the heart of it is the spirit; that what we call the will is not an accident, not a delusion, not some by-product of nature, but is the very secret of life; and that behind it is a vast ocean of power, which now and then sweeps away all dykes, and floods into the human consciousness. The writer of this book is now a patient and plodding teacher of a certain economic doctrine, a preacher of what he might call anti-parasitism. He has come to the conclusion that the habit of men to enslave their fellows and exploit them and draw their substance from them without return--that this habit is destructive to all civilization, and is incompatible with any of the higher forms of life, intellectual, moral or artistic. He has come to the conclusion that there is no use attempting to build a structure of social life until there is a sound foundation; in other words, until the capitalist system has been replaced by cooperation. But in his youth he was, or thought he was, a poet, and touched upon that strange and wonderful thing which we call genius. He saw his own consciousness, as it were a leaf driven before a mighty tempest of spiritual energy. And he believes that this experience was no delusion, but was a revelation of the hidden mysteries of being. He still has memories of this startling experience, still hints of it in his consciousness; something still leaps in his memory, like a race-horse, or like the war-horse of Revelations, which "scenteth the battle afar off, the thunder of the captains and the shouting." Because of these things he can never accept any philosophy which shackles the human spirit, he will never in his thought attempt to set bounds to the possibilities of human life. The very heart of life beats in us, the wonder of it and the glory of it swells like a tide behind us. New universes are born in us, or, if you prefer, they are made by us; and the process is one of endless joy, of rapture beyond anything that the average man can at present imagine, or that any instruments invented by science can weigh or measure. CHAPTER XII THE MIND OF THE BODY (Discusses the subconscious mind, what it is, what it does to the body, and how it can be controlled and made use of by the intelligence.)
