25a.2 · The purpose of a threefold division
I.49.25a.2 · Wachsmuth pp. 350
In Plato and in Aristotle’s ethical writings, the soul is said to have three parts. This view has prevailed among the many, who do not recognize that the division has been adopted for the purpose of establishing the virtues, rather than simply to encompass all the parts. For surely the imaginative, the perceptive, the intellective, and ⟨the⟩ nutritive powers will not be included in this division.1370
25a.3 · Two souls and their interaction
I.49.25a.3 · Wachsmuth pp. 350-351
Others, including Numenius, think that we possess not three parts of one soul, or even two, the rational and the irrational, but two souls, as we do other things: one rational and the other irrational. Among them, some consider both immortal; others consider the rational soul immortal, while the irrational not only ceases its characteristic motion in its activities, but is also dissolved in its substance. Others held that, when two souls are interwoven with each other in the same place, their movements are twofold: the souls become like one another because, in their union, each shares in what the other undergoes.1371
25a.4 · Parts require a different underlying subject
I.49.25a.4 · Wachsmuth pp. 351
We must explain how a power differs from a part. A part differs in kind from the character of another part, whereas powers concern the same kind. That is why Aristotle rejected parts in the case of the soul, but did not reject powers: having different parts immediately introduces a difference in the underlying subject, whereas having different powers can occur in one underlying subject.1372
25a.5 · Longinus: one thing with many powers
I.49.25a.5 · Wachsmuth pp. 351
Longinus holds that even the living creature does not have many parts, but is without parts while having many powers. He cites Plato’s saying that soul becomes divided into many parts in bodies, although in itself it is without parts. Because it does not have many parts, it does not follow that it has only one power: a single thing without parts can have several powers.1373
25a.6 · A criterion for distinguishing the accounts
I.49.25a.6 · Wachsmuth pp. 351-352
Perhaps, then, we must sort out this great confusion by setting a criterion for recognizing difference and lack of difference in respect of parts; then for distinguishing powers from parts and from one another; and then, at a higher level, substances, asking whether several could exist in one. This will make it possible to know whether the soul in a living creature has many parts or only many powers. We can then decide whether to agree with those who confine one soul within the human being but say that it has many parts, either in itself or when it comes to be within that human being; or whether there was a conjunction of several souls, and the human being most resembled a choir singing together, possessing unity through the concord of those who make up the whole; or whether the differentiated plurality belonged to something one in substance.1374
25a.7 · Part, constitution, and power
I.49.25a.7 · Wachsmuth pp. 352
We must therefore explain that power, part, and constitution differ in the case of soul as follows. A part is what differs from another part in its underlying subject, its form, and its activities. Constitution is the fitness proper to the parts for that to which they are naturally suited. Power is a state of that constitution enabling activity in accordance with the way each thing is constituted. Some, however, have said that constitution and power are the same.1375
25a.8 · An apple’s powers and its pieces
I.49.25a.8 · Wachsmuth pp. 352
A power differs from a part. ⟨For powers⟩ are observed in plurality throughout one and the same underlying whole, without being limited to one quantity and [in] another of the underlying substance. Parts, however, take for themselves a certain quantity of the substance and circumscribe a distinct portion of it. For example, an apple’s powers are all in one thing, whereas its parts are separated in different places. The concept of a part concerns quantity, since a part takes a smaller quantity in relation to the constitution of the whole; the concept of a power has taken in the conception of the whole. Hence powers are without parts and extend throughout the whole, whereas parts are lesser, having the quantity of a portion instead of that of the whole.1376
25a.9 · One soul, activities in different bodily regions
I.49.25a.9 · Wachsmuth pp. 353
How, then, is soul without parts and yet threefold? Those who understand the soul’s parts quantitatively are understandably puzzled about how it can be both without parts and threefold. They resolve the difficulty by saying that, according to its own account and in itself, it is without parts, but that it is threefold in so far as, coming to be in a divisible body, it occupies different parts of that body for its different activities. For it is certainly not ⟨the⟩ soul itself that possesses a head, a chest, and a liver; rather, the different activities occurring through these, distributed among different bodily parts, have transferred division back to the soul from those parts.1377
25a.10 · Nicolaus: qualitative divisions
I.49.25a.10 · Wachsmuth pp. 353
Nicolaus did not think that the parts of the soul should be understood quantitatively, but rather qualitatively, like the parts of an art or of philosophy. In the case of quantity, the whole is completed from its parts and, in comparison with something else, becomes more or less, smaller or greater, when a part is added or removed. But we do ⟨not⟩ speak of parts of soul in this way. Its quantity is not completed by them, since it is neither a magnitude nor possessed of a plurality. We speak instead as we do of the parts of an art.1378
25a.11 · The limit of the analogy with an art
I.49.25a.11 · Wachsmuth pp. 353
But soul differs from these as well. An art, ⟨if⟩ some part is absent, would not be whole or complete. Every soul, however, is complete, while every living creature that has not attained its natural end is incomplete.1379
25a.12 · Powers of the being that possesses soul
I.49.25a.12 · Wachsmuth pp. 353-354
Nicolaus therefore understands the parts of soul as powers of the being that possesses it. For a living creature, and in general anything ensouled, can do many things by possessing soul: live, perceive, move, think, and desire. Soul is the cause and source of all these. Accordingly, as has been said, he posits as parts of soul those powers by which the ensouled being is said to do or undergo these things. ⟨But⟩ nothing prevents the being from receiving in a divided manner the activities imparted by soul, although soul itself is without parts.1380
