Action. For /In/ the idea of action, the idea of motion is an essential ingredient. But to actual action actual motion can scarcely be regarded as necessary. Action is either motion itself or a /the/ tendency to motion. Under the term action, besides motion a tendency, though so it be without actual motion, seems to be included. Held back by strings, a magnet and a bar of iron, suspended at a certain distance from each other, remain both of them without motion: cut the strings of either of them, it moves till it comes in contact with the other; but for the state of mutual action which preceded the cutting of the strings no such motion would have taken place.

    Subject - Object - Subject - {Concomitance} - {End}

    Groups of Concomitant entities considered and denominated in respect of their concomitancy.

    In the idea of an object the idea of some action or at any rate some motion seems to be constantly and [...?] /essentially/ involved. Where the object is a corporeal entity, it is a body towards which the body in motion moves: this body whether permanently or momentarily stands objected i.e. cast before that other body which moves.

    Even in the case of vision, in the instance of an object of sight, the relation is naturally the same; the only difference is that, in the case of vision, the moving bodies being the rays of light, the object instead of being the body towards which, is the body from which, the motion takes place.

    In the image /picture/ the tracing of which is the effect of the terms /names/ here in question the object is either on the same level with the source of motion, or above it: the subject, as in its literal sense the word subject imports, is below and under it.

    In the case of human action - a motion, real or fictitious considered as being produced by an exercise of the faculty of the will, on the part of a sensitive being, this action has, in every instance, for its cause, the desire and expectation of some good i.e. of some pleasure or exemption from some pain, and the entity, the good by which this desire has been produced, is in this case, if not the only object, an object, and, indeed, the ultimate object, the attainment of which is, in the performance of the action aimed at.

    Productive and unproductive - whether in actual result or only in tendency under one or other of these denominations may also be referred every motion or set of motions of the athelematic kind - every motion, or set of motions produced in, by and upon such agents as are of the purely physical kind.

    This distinction is applicable to all these /all the three physical/ kingdoms: though /but/ on the mention of it, the two living kingdoms - the vegetable and the animal - will be most apt to present themselves.
