substance pressing against another portion of substance; and that force can be nothing else than this. And we see that pressure causes motion, and that motion, in turn, causes pressure; so that force and motion are mutually convertible, each into the other. Also, we see that there is only one force, the pressure of substance; and that all the so-called “forces” of nature are merely different rates and modes of motion, and have their origin in the One Force--pressure of substance. Furthermore, we see that there is no such thing as a universal attraction which bodies exert upon each other, but that there is a universal pressure, impelling all bodies toward each other in a definite and orderly way; and to the study of this universal pressure we will next turn our attention. Time, space, substance and motion exist. Substance is conscious. Motion is caused by pressure of substance against substance, and the varying forms of substance in the visible creation are caused by differences in motion. VI. THE BEGINNING OF MOTION. ORIGIN OF MOTION--AN EXPOSITION OF FORCE AND MOTION FOUNDED ON THE THEORY OF SPACE BEING OCCUPIED BY A FLUID CONSCIOUS SUBSTANCE--HAS MOTION EVER A BEGINNING?--WILL AND WILL-PRESSURE ON MOTION--WILL OF GOD THE ONE COMPELLING POWER To understand force and motion, we must go back to a supposititious creation. Conceive, first, of space as being occupied by completely conscious substance in a perfectly fluid state; conscious throughout, alike throughout, and without motion. Now, can you conceive of motion as beginning in any part of this substance without an act of will? Can you think of your conscious self as beginning to act, and as continuing to act in an orderly and consecutive series of motions without an effort of will? If, as we have seen, original substance is completely conscious, then its every motion must be a conscious motion; and we cannot think of conscious motion without will. You are aware that you can consciously originate motion yourself; but you cannot do it without will. You are conscious substance; you can be nothing else as we have seen, and you can move or cease to move by an exertion of your will, and in moving or ceasing to move you cause the body you inhabit to move or cease to move. We see motion beginning and ceasing all around us; and we conclude that every motion had a beginning; and that the beginning of the series of creative motions which have resulted in the present universe of forms could only have been in an action of the will of Original Conscious Substance.
