Enneads VI.1: Of the Ten Aristotelian and Four Stoic Categories
Transmission, Reception and Relation Underlie Action and Experience
22The cause that a being undergoes an experience is that it contains the kind of movement called alteration, whichever way it modify him; on the contrary, action means to have in oneself a definite movement, derived from oneself, or a movement which has its goal in some other being, and its origin in self. In both cases there is movement; but with this distinction: that action, so far as it is action, is impassible; while an experience consists in the experiencer’s reception of a disposition new to him, without the reception of anything that contributes towards his being; so as to avoid (the case of the statue, above, where) the experience happened to one being (the metal), while it was another being that was produced (the statue). Consequently, the same thing will in one state be an action, and in other, an experience. Thus the same movement will in one being be an action, because it is considered from a certain viewpoint; and from another it will be an experience, because it is disposed some other way. Action and experience seem therefore to be relative, if one consider the action in its relation with experience, since the same thing is action in the one, and experience in the other. Also, because neither of these two can be considered in itself, but only in him who acts, or experiences, when the one moves, and the other is moved. Each of these terms therefore implies two categories; one gives the movement, the other receives it; consequently we have transmission and reception, which result in relation. If he who received the movement possesses it as he possesses color, why could it not also be said that he possessed movement? Absolute movements, such as walking (and thinking) possess steps and thought.
PREDICTION AND RESPONSIVENESS TO IT DO NOT FALL UNDER DEFINITION FOR ACTION AND EXPERIENCE.
Let us now consider whether prediction be an action, and whether adapting one’s course to the prediction of somebody else would constitute experiencing; for prediction comes from one being and applies to another. However, although prediction apply to some other, we would not consider prediction an action, nor being directed by the prediction of somebody else an experience. In general, not even thought is an action; thought, indeed, does not pass in to the object thought, but functions within itself; it is not at all an action. Actualizations are not at all actions, and not all of them perform actions; indeed, they may do so only accidentally. It might be objected that a man who was walking would certainly impress on the ground the trace of his steps, and would thereby perform an action. Such an action would be the consequence of something else, or the man would act accidentally; and it would be accidental, because the man was not thinking of it. It is in this way that even inanimate things perform some action, that fire heats, and medicine cures. But enough of this.
23Let us now examine the category of “having” (possession).
HAVING IS SO INDEFINITE AND VARIOUS THAT IT CANNOT BE A CATEGORY.
If the verb “to have” be used in several senses, why might we not apply to this category all the various uses of the word; for instance, quantity, because quantity has size; quality, because it has color; the father, because he has a son; the son, because he has a father; and, in general, all kinds of possession? Will it be said that the other things that can be possessed have already been classified under the categories considered above, and that the category of “having” comprises only arms, foot-wear, and clothing? This might be answered by the question why “having” these objects should constitute a category, and why burning them, cutting them, burying them, or throwing them away, would not equally constitute one or more categories? If the answer be that all these things form one category because they refer to the body, this would then also make another category if we placed a garment over a litter; or likewise if someone were covered with clothing. If another answer be that the category of “having” consists in the “manner of containing,” and in possession, then all things which are possessed will have to be reduced to this category, which will thus contain all possession, whatever it be, since the nature of the possessed object could not here prevail to form some distinction. On the other hand, if the category of “having” must exclude having a quantity or quality, because the latter ideas already form their own categories; nor having parts, because of the category of being (which includes parts); why should this category contain having arms, when arms, as well as foot-wear, belong to the category of being? In any case, how could the statement, “He has arms” be considered something simple, which could be reduced to any one category? That statement expresses the same idea as “He is armed.” Can this expression (“he has arms”) refer only to a man, or even to his statue? The living man possesses very differently from possession by a statue, and the verb “to have” is used only as a verbal label (a homonym), just as the verb “to stand up” would mean something very different according as it referred to a man or a statue. Besides, is it reasonable to make a generic category of some merely incidental characteristic?
24As to the category of situation, it contains also such incidental characteristics as being raised, or seated. Here the Aristotelians do not make a category of situation, by itself, but of the kind of situation, as when it is said, “He is placed in such a posture”—a phrase in which “to be placed” and “in such a posture” express two entirely different ideas—or again, “he is in such a place.” Now, as posture and location have already been studied, what is the use in here combining two categories into one? If, on the other hand, the expression “he is seated” indicate an action or an experience, must it not then be reduced to the category of action or experience? It would moreover amount to the same thing to say “he is raised,” as to say, “he is situated above;” just as we say he is situated in the middle, or, he is situated below. Besides, being seated has already been treated of under the category of relation; why should, “being raised” not also be a relative entity, since the category of relation includes the thing to the left, and the thing to the right, as well as the left and right hand themselves?
Enough of these reflections (about Aristotelian categories).
25Let us now pass to the (Stoic) philosophers who, recognizing four categories only, divide everything into “substances,” “qualities,” “modes,” and “relations;” and who, attributing to all (beings) something common, thus embrace them into a single genus.
