practical want--a standard unit, by which it measures parts in Space and Time. So motion must be measured by some assumed standard; and as, like time,--duration,--it can be represented by a line, let them have a common standard. Suppose, then, that the ball's flight occupies ten minutes of time. The line from m to z will be divided into ten exactly equal spaces; and it will be no more difficult to account for the flow of force from 10 to 9, than from 1 to 0. Also let it be observed that the force, like time, is a unit, which the Sense, for its convenience, divides into parts; but that neither those parts, nor any parts, have any real existence. As Time is an indivisible whole, measured off for convenience, so any given force is such a whole, and is so measured off. All this appearing and measuring are phenomenal in the Sense. It is the Reason which sees that they can be _only_ phenomenal, and that behind the appearance is pure Spirit--God, who is primarily out of all relation. On page 58, near the close of his illustration of the chair, Mr. Spencer says: "It suffices to remark that since the force as known to us is an affection of consciousness, we cannot conceive the force as existing in the chair under the same form without endowing the chair with consciousness." This very strange assertion can only be true, provided a major premiss, No force can be conceived to exist without involving an affection of consciousness in the object in which it _apparently_ inheres, is true. Such a premiss seems worse than absurd; it seems silly. We cannot learn that force exists, without our consciousness is affected thereby; but this is a very different thing from our being unable to conceive of a force as _existing_, without there is a consciousness in the object through which it _appears_. If Mr. Spencer had said that no force can be, without being exerted, and no force can be exerted, without an affection of the consciousness of the exertor, he would have uttered the truth. We would then have the following result. Primarily all force is exerted by the Deity; and he is conscious thereof. He draws the chair down just as really as though the hand were visible. Secondarily spiritual persons are endowed by their Creator with the ability to exert his force for their uses, and so I lift the chair. The great error, which appears on every page of Mr. Spencer's book and invalidates all his conclusions, shows itself fully here. He presents images from the Sense, and then tries to satisfy the Reason--the faculty which calls for an absolute account--by the analyses of that Sense. His attempt to "halve the rate," his remark that "the smallest movement is separated by an impassable gap from no movement," and many such, are only pertinent to the Sense, can never be explained by the Sense, and are found by the Reason to need, and be capable of, no such kind of explanation as the Sense attempts; but that the phenomena are
