In all our acts, in all without exception, we have no consciousness of the direction imparted by our will. When you explain to me how I lift my hand, I will explain to you how I make the table-leg rise from the floor. I "willed to raise my hand." Yes, and I also willed to lift this table-leg. As for the executing of the mandates of the will, the putting into play of the muscles required to lift the hand, or of the fluid-power required to lift the table-leg, I have no knowledge of what passes in me apropos of this. Strange mystery, and one which ought to inspire in us a little modesty! There is in me an executive power, a power of such a nature that, when I have willed such or such an act, it addresses detailed orders to the different muscles and sets in motion a hundred complicated movements to bring about a final result which has been merely thought of, merely willed. That miracle goes on within me, and I understand it not at all, and never shall understand it. Do you not agree that the same executive power can give to the fluid the directions it gives to the muscles? I have willed to play a sonata on the piano, and, unknown to me, something within me has given orders to hundreds of thousands of muscular acts. I have willed that the leg of this table should be lifted up, and, unknown to me, something within me has directed the attractions and impulsions of the fluid to the designated place. The hypothesis of a fluid is, then, defensible. It accords with the nature of things and with the nature of man. I have no wish to go farther and furnish at once a definitive explanation. But I am not worrying. Let the facts once be admitted, and explanations will not be wanting. What seems impossible now will seem very simple then. About incontestable things no trouble is made. We are so constituted that, after we have asserted the impossibility of everything we do not comprehend, we declare comprehensible all that we have recognized as real. People are everywhere to be met with who shrug their shoulders when you speak to them of table-turnings and who make nothing of the Puck-like performance of the electric current in putting the girdle of its circuit around the earth in the fraction of a moment, and who find the miracle of the transmission of the mental and moral qualities of the fathers to the children a very simple thing to understand! The tables of the psychic experimenter cannot escape the common lot. Their phenomena, absurd to-day, are to-morrow self-evident. These experiments of Count de Gasparin and his associates have been known for over half a century, and it is really incomprehensible that even the fact of the levitation of tables and of their movements has continued to be denied. Verily, if the tables are sometimes light, it must be confessed that the human race is a little heavy.
