It may be asked, where does this force go to when the motion diminishes till the body stops. It passes into the substances which cause the diminution until there is no surplus in the moving body, and at the point of equilibrium motion ceases. If it be now asked, where does this force ultimately go to, it is to be said that it comes from God, and goes to God, who is the Final. The Sense gives only subordinate answers, but the Reason leads us to the Supreme. If the view adopted be true, Mr. Spencer's halving and halving again "the rate of movement forever," is irrelevant. It is not a _mental operation_ but an _actual fact_ which is to be accounted for. Take a striking illustration. A ball lying on smooth ice is struck with a hockey. Away it goes skimming over the glassy surface with a steadily diminishing velocity till it ceases. It starts, it proceeds, it stops. These are the facts; and the mental operation must accord with them. There is put into the ball, at the instant of contact, a certain amount of motor force. From that instant onward, that force flows out of the ball into the resisting substances by which it is surrounded, until none is left. And it is just as pertinent to ask how all the water can flow out of a pail, as how all the motor force can flow out of a moving substance. "The smallest movement is separated" by no more of "an impassable gap from no movement," _than it is from a larger movement above it_. That which will account for a movement four becoming two, will account for a movement two becoming zero. The "puzzle," then, may be explained thus. Time is the procession of events. Let it be represented by a line. Take a point in that line, which will then mark its division but represent _no period_. On one side of that point is rest; on the other motion. That point is the point of contact, and occupies no period. At this point the motion is maximum. The force instantly begins to flow off, and continues in a steady stream until none is left, and the body is again at rest. Here, also, we take a point. This is the point of zero. It again divides the line. Before the bisection is motion; after the bisection is rest. All this cannot be perceived by the Sense, nor conceived by the Understanding. It is seen by the Reason. Now observe the actual phenomenon. The ball starts, proceeds, stops. From maximum to zero there is a steady diminution, or nearly enough so for the experiment; at least the diminution can be averaged for the illustration. Then comparing motion with time, the same difficulty falls upon the one as the other. If the motion is halved, the time must be; and so, "mentally," it is impossible to imagine how a moment of time can pass. To the halving faculty--the Sense--this is true, and so we are compelled to correct our course of procedure. This it is. The Sense and Understanding being impotent to discover an absolute unit of any kind, the Sense _assumes_ for itself what meets all
