At every step the subject of consideration becomes more and more complicated.

Rest is the absence or negation of motion. Every body is either in motion, or at rest. Here place, i.e. relative space is still the archetype. Motion is a thing an imaginary, an involuntarily imagined substance in which the body is conceived as being placed: rest a like body, at which the real body is considered as being placed.

In the idea /consideration/ /notion/ of motion that of time is moreover involved; and again that of place, as being that in which the idea of time is, by the like necessity, involved.

In motion a body cannot have been but it must have been in two different places, at or in two different, which is as much as to say, in two successive portions of time.

For the space of time in question, i.e. for a portion of time composed of those same portions which were operative in the case of motion, the body has been at rest, in so far as in all that space or length of time it has not changed its place with reference to any others.

Taken in the aggregate, in so far as can be concluded, either from observation or from analogy in the way of inference, no body whatsoever is, or ever has been, or ever will be, absolutely in a state of rest, i.e. without being in motion with reference to some other body or bodies.

    Considered with reference to our senses every particle

    of matter perceived or perceptible at the time at which, or with reference to which it is considered, is either in a state of motion or in a state of rest.

    A /The/ state of rest is the negation of the state of motion. With reference to the same object, no particle of matter can therefore be in motion and at rest at the same time. To say that it is or can be, would be a self-contradictory proposition, resolvable into a pair of mutually contradictory propositions.

    But take any body composed of a number of particles of matter, then so it is that, of and in the same body, while part, i.e. some of those particles, are in a state of motion, other parts may at that time be in a state of rest.

    When of any body it is said, that body has been in motion, what is meant is, that, at or in different portions of the field of time, that body has occupied different portions or positions in the field of space.

    As atoms or minimum portions may be conceived as having place in the field of space, so may atoms or minimum portions in the field of time.

    If, speaking of any body suppose the plaything called a peg-top. I say this body is now in motion; then, if by now I mean no more than a single atom or minimum portion of time, what I thus say cannot be exactly true, since, as above, for motion to have had place, or to have place, two atoms of time at the least are necessary.

    The earth which we inhabit is not at rest. The sun himself about which she moves is not at rest. The stars called fixed being but so many suns, are themselves no more at rest than is he.

    Considered as a whole the parts of our earth are, as far as appears, with reference to one another, the greater part of them always at rest, - others, especially those near the surface, many of them occasionally in motion: and so in regard to the several separate bodies, consisting of such portions of the matter of which the earth is composed, as are detached and separate from one another, each of them having between itself and every other, with the exception of the base on which it stands, and upon which, by the principle of attraction under the several forms under which it operates, it is kept at that place, certain portions of intervening space.

    Of such of them as are in a state of solidity, rest, relative rest, rest with relation to each other, in so far as they are in that state, is the naturally constant state. In motion they are not put but by some supervening accident operating from without. Of such of them as are in a state of fluidity, liquidity and gaseosity included, motion, relative motion is, in every instance, a natural state, exemplified to a greater or lesser extent, depending partly on the particular qualities of the several fluids, partly upon the accidents ab extra to which, individually taken, they happen to be /have been/ exposed.

    In addition to the notion /idea/ of motion, in the ideas of action and passion the notion of causation or causality is involved /superadded/. The body F is in motion: of that /such/ motion what is the cause ? Answer - the action of another body, the body S, which by the exercise exertion influence or correspondent power which it has /possesses/ becomes productive of that effect.

    In themselves, the two fictitious entities Action and Passion are not only correspondent but inseparable. No action without passion: no passion without action: no action on the one part without passion on the other.

    In the case of action and thereupon on the part of one of two bodies - motion - sensible /perceptible/ motion, on the part of the other body is relative motion, in every instance a never failing consequence ? To judge from analogy the probability seems to be in the affirmative.

    Where /In so far as/ on the part of one of the two alone any motion is perceptible on the part of the other no motion being perceptible, the one of which the motion is perceptible, is most commonly spoken of as the agent, the other as the patient: a state of motion is the state in which the former is said to be in, a state of passion, the state in which the other is said to be in.
