another vast period that point is reached when an animal may be organized, which shall be the dwelling-place for a time of a being whose life is utterly different in kind from any animal life, and man appears. Now in all these vast processes, be it observed that God is personally present, that the first energy was his, and that every subsequent energizing act is his special and personal act. He organized the duality, force. He then organized this force into heat-force, light-force, magnetic-force, matter-force, life-force, and soul-force. And so it is that his personal supervision and energy is actually present in every atom of the Universe. When we turn from this process of thought to the sensible facts, and speak of granite, sandstone, schist, clay, herbage, animals, yes, of the thousand kinds of substance which appear to the eye, it is to be remembered that all these are but _forms to the Sense_ of that "reason-conception," force,--that primal duality, which power acting upon itself becomes. Now as the machine can never carve any other image than those for which it is specially constructed, and must work just as it is made to work, so the Sense, which is purely mechanical, can never do any other than the work for which it was made, can never transcend the laws of its organization. It can only give forms--results, but is impotent to go behind them. It can only say _that things are_, but never say _what_ or _why_ they are. Seen in the light of the theory which has thus been presented, Mr. Spencer's difficulties vanish. Matter is force. Motion is matter affected by another form of force. The "puzzle" of motion and rest is only phenomenal to the Sense; it is an appearance of force acting through another force. It may also be said that the Universe is solid force. There is no void in it. There is no nook, no crevice or cranny, that is not full of force. To seek, then, for some medium through which force may traverse vast distances, is the perfection of superfluity. From centre to circumference it is present, and controls all things, and is all things. So it is no more difficult to see how force reaches forth and holds worlds in their place, than how it draws down the pebble which a boy has thrown into the air. It is no substance which must travel over the distance, it is rather an inflexible rod which swings the worlds round in their orbits. Whether, then, we look at calcined crags or lilies of the valley, whether astronomy, or geology, or chemistry be our study, the objects grouped under those sciences will be found to be equally the results of this one force, acting under different laws, and taking upon itself different forms, and becoming different objects.
