Whether the circumstances are properly set forth in the third book of Ethics?
Objection 1: It would seem that the circumstances are not properly set forth in Ethic. iii, 1. For a circumstance of an act is described as something outside the act. Now time and place answer to this description. Therefore there are only two circumstances, to wit, "when" and "where."
Objection 2: Further, we judge from the circumstances whether a thing is well or ill done. But this belongs to the mode of an act. Therefore all the circumstances are included under one, which is the "mode of acting."
Objection 3: Further, circumstances are not part of the substance of an act. But the causes of an act seem to belong to its substance. Therefore no circumstance should be taken from the cause of the act itself. Accordingly, neither "who," nor "why," nor "about what," are circumstances: since "who" refers to the efficient cause, "why" to the final cause, and "about what" to the material cause.
On the contrary is the authority of the Philosopher in Ethic. iii, 1.
I answer that, Tully, in his Rhetoric (De Invent. Rhetor. i), gives seven circumstances, which are contained in this verse:
"Quis, quid, ubi, quibus auxiliis, cur, quomodo, quando---
Who, what, where, by what aids, why, how, and when."
For in acts we must take note of "who" did it, "by what aids" or "instruments" he did it, "what" he did, "where" he did it, "why" he did it, "how" and "when" he did it. But Aristotle in Ethic. iii, 1 adds yet another, to wit, "about what," which Tully includes in the circumstance "what."
The reason of this enumeration may be set down as follows. For a circumstance is described as something outside the substance of the act, and yet in a way touching it. Now this happens in three ways: first, inasmuch as it touches the act itself; secondly, inasmuch as it touches the cause of the act; thirdly, inasmuch as it touches the effect. It touches the act itself, either by way of measure, as "time" and "place"; or by qualifying the act as the "mode of acting." It touches the effect when we consider "what" is done. It touches the cause of the act, as to the final cause, by the circumstance "why"; as to the material cause, or object, in the circumstance "about what"; as to the principal efficient cause, in the circumstance "who"; and as to the instrumental efficient cause, in the circumstance "by what aids."
Reply to Objection 1: Time and place surround [circumstant] the act by way of measure; but the others surround the act by touching it in any other way, while they are extrinsic to the substance of the act.
Reply to Objection 2: This mode "well" or "ill" is not a circumstance, but results from all the circumstances. But the mode which refers to a quality of the act is a special circumstance; for instance, that a man walk fast or slowly; that he strike hard or gently, and so forth.
Reply to Objection 3: A condition of the cause, on which the substance of the act depends, is not a circumstance; it must be an additional condition. Thus, in regard to the object, it is not a circumstance of theft that the object is another's property, for this belongs to the substance of the act; but that it be great or small. And the same applies to the other circumstances which are considered in reference to the other causes. For the end that specifies the act is not a circumstance, but some additional end. Thus, that a valiant man act "valiantly for the sake of" the good of the virtue or fortitude, is not a circumstance; but if he act valiantly for the sake of the delivery of the state, or of Christendom, or some such purpose. The same is to be said with regard to the circumstance "what"; for that a man by pouring water on someone should happen to wash him, is not a circumstance of the washing; but that in doing so he give him a chill, or scald him; heal him or harm him, these are circumstances.
I–II · Q. 7, Art. 4: Whether the most important circumstances are 'why' and 'in what the act consists'?
Whether the most important circumstances are "why" and "in what the act consists"?
Objection 1: It would seem that these are not the most important circumstances, namely, "why" and those "in which the act is, [*hen ois e praxis]" as stated in Ethic. iii, 1. For those in which the act is seem to be place and time: and these do not seem to be the most important of the circumstances, since, of them all, they are the most extrinsic to the act. Therefore those things in which the act is are not the most important circumstances.
Objection 2: Further, the end of a thing is extrinsic to it. Therefore it is not the most important circumstance.
Objection 3: Further, that which holds the foremost place in regard to each thing, is its cause and its form. But the cause of an act is the person that does it; while the form of an act is the manner in which it is done. Therefore these two circumstances seem to be of the greatest importance.
On the contrary, Gregory of Nyssa [*Nemesius, De Nat. Hom. xxxi.] says that "the most important circumstances" are "why it is done" and "what is done."
I answer that, As stated above (Q 1, A 1), acts are properly called human, inasmuch as they are voluntary. Now, the motive and object of the will is the end. Therefore that circumstance is the most important of all which touches the act on the part of the end, viz. the circumstance "why": and the second in importance, is that which touches the very substance of the act, viz. the circumstance "what he did." As to the other circumstances, they are more or less important, according as they more or less approach to these.
Reply to Objection 1: By those things "in which the act is" the Philosopher does not mean time and place, but those circumstances that are affixed to the act itself. Wherefore Gregory of Nyssa [*Nemesius, De Nat. Hom. xxxi], as though he were explaining the dictum of the Philosopher, instead of the latter's term---"in which the act is"---said, "what is done."
Reply to Objection 2: Although the end is not part of the substance of the act, yet it is the most important cause of the act, inasmuch as it moves the agent to act. Wherefore the moral act is specified chiefly by the end.
Reply to Objection 3: The person that does the act is the cause of that act, inasmuch as he is moved thereto by the end; and it is chiefly in this respect that he is directed to the act; while other conditions of the person have not such an important relation to the act. As to the mode, it is not the substantial form of the act, for in an act the substantial form depends on the object and term or end; but it is, as it were, a certain accidental quality of the act.
