LESSON II

The Number and Relationship of Simple Enunciations in Which the

Verb "Is" Is Predicated As a Third Element and the Subject Is the

Finite Name Not Universally Taken

             19b 19 But when "is" is predicated as a third element in the enunciation, there are two oppositions.

             19b 20 I mean by this that in an enunciation such as "Man is just," the "is" is a third name or verb contained in the affirmation.

             19b 22 In this case, therefore, there will be four enunciations, two of which will correspond in their sequence, in respect of affirmation and negation, with the privations but two will not.

             19b 24 I mean that the "is" will be added either to "just" or to "nonjust"; and so also in the case of the negative. Thus there will be four.

             19b 27 The following diagram will make this clear.

[[

Diagram #1 (Image 1)]]

Here the "is" and the "is not" are added to "just" and "nonjust." This, then, is the way these are arranged, as we have said in the Analytics.

             1. After distinguishing enunciations in which either a finite or an infinite name is posited only on the part of the subject, the Philosopher begins here to distinguish enunciations in which either a finite or an infinite name is posited as the subject and as the predicate. First he distinguishes these enunciations, and then he manifests certain things that might be doubtful in relation to them where he says, Since the negation contrary to "Every animal is just," is the one signifying "No animal is just," etc. With respect to their distinction he first deals with enunciations in which the name is predicated with the verb "is"; secondly, with those in which other verbs are used, where he says, In enunciations in which "is" does not join the predicate to the subject, for example, when the verb "matures" or "walks" is used, etc.

             He distinguishes these enunciations as he did the primary enunciations, according to a threefold difference on the part of the subject, first treating those in which the subject is a finite name not taken universally, secondly, those in which the subject is a finite name taken universally where he says, The same is the case when the affirmation is of a name taken universally, etc. Thirdly, he treats those in which an infinite name is the subject, where he says, and there are two other pairs, if something is added to "non-man" as a subject, etc. With respect to the first enunciations [in which the subject is a finite name not taken universally] he proposes a diversity of oppositions and then concludes as to their number and states their relationship, where he says, In this case, therefore, there will be four enunciations, etc. Finally, he exemplifies this with a table.

             2. In relation to the first point two things have to be understood. First, what is meant by "is" is predicated as a third element in the enunciation. To clarify this we must note that the verb "is" itself is sometimes predicated in an enunciation, as in "Socrates is." By this we intend to signify that Socrates really is. Sometimes, however, "is" is not predicated as the principal predicate, but is joined to the principal predicate to connect it to the subject, as in "Socrates is white." Here the intention is not to assert that Socrates really is, but to attribute whiteness to him by means of the verb "is." Hence, in such enunciations "is" is predicated as added to the principal predicate. It is said to be third, not because it is a third predicate, but because it is a third word posited in the enunciation, which together with the name predicated makes one predicate. The enunciation is thus divided into two parts and not three.

             3. Secondly, we must consider what he means by when "is" is predicated as a third element in the enunciation, in the mode in which we have explained, there are two oppositions. In the enunciations already treated, in which the name is posited only on the part of the subject, there was one opposition in relation to any subject. For example, if the subject was a finite name not taken universally there was only one opposition, "Man is," "Man is not." But when "is" is predicated in addition there are two oppositions with regard to the same subject corresponding to the difference of the predicate name, which can be finite or infinite. There is the opposition of "Man is just," "Man is not just," and the opposition, "Man is nonjust," "Man is not nonjust." For the negation is effected by applying the negative particle to the verb "is," which is a sign of a predication.

             4. When he says, I mean by this that in an enunciation such as "Man is just," etc., he explains what he means by when "is" is predicated as a third element in the enunciation. When we say "Man is just," the verb "is" is added to the predicate as a third name or verb in the affirmation. Now "is," like any other word, may be called a name, and thus it is a third name, i.e., word. But because, according to common usage, a word signifying time is called a verb rather than a name Aristotle adds here, or verb, as if to say that with respect to the fact that it is a third thing, it does not matter whether it is called a name or a verb.

             5. He goes on to say, In this case, therefore, there will be four enunciations, etc. Here he concludes to the number of the enunciations, first giving the number, and then their relationship where he says, two of which will correspond in their sequence, in respect of affirmation and negation, with the privations but two will not. Finally, he explains the reason for the number where he says, I mean that the "is" will be added either to "just" or to "nonjust," etc.

             He says first, then, that since there are two oppositions when "is" is predicated as a third element in the enunciation, and since every opposition is between two enunciations, it follows that there are four enunciations in which "is" is predicated as a third element when the subject is finite and is not taken universally. When he says, two of which will correspond in their sequence, etc., he shows their relationship. Two of these enunciations are related to affirmation and negation according to consequence (or according to correlation or proportion, as it is in the Greek like privations; the other two are not. Because this is said so briefly and obscurely, it has been explained in diverse ways.

             6. Before we take up the various explanations of this passage there is a general point in relation to it that needs to be clarified. In this kind of enunciation a name can be predicated in three ways. We can predicate a finite name and by this we obtain two enunciations, one affirmative and one negative, "Man is just" and "Man is not just." These are called simple enunciations. Or, we can predicate an infinite name and by this we obtain two other enunciations, "Man is nonjust" and "Man is not nonjust." These are called infinite enunciations. Finally, we can predicate a privative name and again we will have two, "Man is unjust" and "Man is not unjust." These are called privative.

             7. Now the passage in question has been explained by some in the following way. Two of the enunciations he has given, those with an infinite predicate, are related to the affirmation and negation of the finite predicate according to consequence or analogy, as are privations, i.e., as those with a privative predicate. For the two with an infinite predicate are related according to consequence to those with a finite predicate but in a transposed way, namely, affirmation to negation and negation to affirmation. That is, "Man is nonjust," the affirmation of the infinite predicate, corresponds according to consequence to the negative of the finite predicate, i.e., to "Man is not just"; the negative of the infinite predicate, "Man is not nonjust," corresponds to the affirmative of the finite predicate, i.e., to "Man is just." Theophrastus for this reason called those with the infinite predicate, "transposed."

             The affirmative with a privative predicate also corresponds according to consequence to the negative with a finite predicate, i.e., "Man is unjust" to "Man is not just"; and the negative of the privative predicate to the affirmative of the finite predicate, "Man is not unjust" to "Man is just." These enunciations can therefore be placed in a table in the following way:

 Man is just   Man is not just

 Man is not nonjust  Man is nonjust

 Man is not unjust  Man is unjust

             This makes it clear that two, those with the infinite predicate, are related to the affirmation and negation of the finite predicate in the way privations are, i.e., as those that have a privative predicate.

             It is also evident that there are two others that do not have a similar consequence, i.e., those with an infinite subject, "Non-man is just" and "Non-man is not just." This is the way Herminus explained the words but two will not, i.e., by referring it to enunciations with an infinite subject. This, however, is clearly contrary to the words of Aristotle, for after giving the four enunciations, two with a finite predicate and two with an infinite predicate, he adds two of which . . . but two will not, as though he were subdividing them, which can only mean that both pairs are comprised in what he is saying. He does not include among these the ones with an infinite subject but will mention them later. It is clear, then, that he is not speaking of these here.

             8. Since this exposition is not consonant with Aristotle's words, others, Ammonius says, have explained this in another way. According to them, two of the four propositions, those of the infinite predicate, are related to affirmation and negation, i.e., to the species itself of affirmation and negation, as privations, that is, as privative affirmations and negations. For the affirmation, "Man is nonjust," is not an affirmation simply, but relatively, as though according to privation; as a dead man is not a man simply, but according to privation. The same thing applies to the negative enunciation with an infinite predicate. However, the two enunciations having finite predicates are not related to the species of affirmation and negation according to privation, but simply, for the enunciation "Man is just" is simply affirmative and "Man is not just" is simply negative.

             But this meaning does not correspond to the words of Aristotle either, for he says further on: This, then, is the way these are arranged, as we have said in the Analytics, but there is nothing in that text pertaining to this meaning. Ammonius, therefore, interprets this differently and in accordance with what is said at the end of I Priorum about propositions having a finite or infinite or privative predicate.

             9. To make Ammonius' explanation clear, it must be noted that, as Aristotle himself says, the enunciation, by some power, is related to that of which the whole of what is signified in the enunciation can be truly predicated. The enunciation, "Man is just," for example, is related to all those of which in any way "is a just man" can be truly said. So, too, the enunciation "Man is not just" is related to all those of which in any way "is not a just man" can be truly said.

             According to this mode of speaking it is evident, then, that the simple negative is wider than the infinite affirmative which corresponds to it. Thus, "is a nonjust man" can truly be said of any man who does not have the habit of justice; but "is not a just man" can be said not only of a man not having the habit of justice, but also of what is not a man at all. For example, it is true to say "Wood is not a just man," but false to say, "Wood is a nonjust man." The simple negative, then, is wider than the infinite affirmative--just as animal is wider than man, since it is verified of more.

             For a similar reason the simple negative is wider than the privative affirmative, for "is an unjust man" cannot be said of what is not man. But the infinite affirmative is wider than the private affirmative, for "is a nonjust man" can be truly said of a boy or of any man not yet having a habit of virtue or vice, but "is an unjust man" cannot. And the simple affirmative is narrower than the infinite negative, for "is not a nonjust man" can be said not only of a just man, but also of what is not man at all. Similarly, the privative negative is wider than the infinite negative. For "is not an unjust man" can be said not only of a man having the habit of justice and of what is not man at all--of which "is not a nonjust man" can be said--but over and beyond this can be said about all men who neither have the habit of justice nor the habit of injustice.

             10. With these points in mind it is easy to explain the present sentence in Aristotle. Two of which, i.e., the infinites, will be related to the simple affirmation and negation according to consequence, i.e., in their mode of following upon the two simple enunciations, the infinitives will be related as are privations, i.e., as the two privative enunciations. For just as the infinite negative follows upon the simple affirmative, and is not convertible with it (because the infinite negative is wider), so also the privative negative which is wider follows upon the simple affirmative and is not convertible. But just as the simple negative follows upon the infinite affirmative, which is narrower and is not convertible with it, so also the simple negative follows upon the privative affirmative, which is narrower and is not convertible. From this it is clear that there is the same relationship, with respect to consequence, of infinites to simple enunciations as there is of privatives.

             11. He goes on to say, but two, i.e., the simple enunciations that are left after the two infinite enunciations have been taken care of, will not, i.e., are not related to infinites according to consequence as privatives are related to them, because, on the one hand, the simple affirmative is narrower than the infinite negative, and the privative negative wider than the infinite negative; and on the other hand, the simple negative is wider than the infinite affirmative, and the privative affirmative narrower than the infinite affirmative. Thus it is clear that simple enunciations are not related to infinites in respect to consequence as privatives are related to infinites.

             12. But although this explains the words of the Philosopher in a subtle manner the explanation appears a bit forced. For the words of the Philosopher seem to say that diverse relationships will not apply in respect to diverse things; however, in the exposition we have just seen, first there is an explanation of a similitude of relationship to simple enunciations and then an explanation of a dissimilitude of relationship in respect to infinites. The simpler exposition of this passage of Aristotle by Porphyry, which Boethius gives, is therefore more apposite.

             According to Porphyry's explanation there is similitude and dissimilitude according to consequence of affirmatives and negatives. Thus Aristotle is saying: Of which, i.e., the four enunciations we are discussing, two, i.e., affirmatives, one simple and the other infinite, will be related according to consequence in regard to affirmation and negation, i.e., so that upon one affirmative follows the other negative, for the infinite negative follows upon the simple affirmative and the simple negative upon the infinite affirmative. But two, i.e., the negatives, will not, i.e., are not so related to affirmatives, i.e., so that affirmatives follow from negatives. And with respect to both, privatives are related in the same way as the infinites.

             13. Then Aristotle says, I mean that the "is" will be added either to "just" or to "nonjust," etc. Here he shows how, under these circumstances, we get four enunciations. We are speaking now of enunciations in which the verb "is" is predicated as added to some finite or infinite name, for instance as it adjoins "just" in "Man is just," or "nonjust" in "Man is nonjust." Now since the negation is not applied to the verb in either of these, each is affirmative. However, there is a negation opposed to every affirmation as was shown in the first book. Therefore, two negatives correspond to the two foresaid affirmative enunciations, making four simple enunciations.

             14. Then he says, The following diagram will make this clear. Here he manifests what he has said by a diagrammatic description; for, as he says, what has been stated can be understood from the following diagram. Take a four-sided figure and in one corner write the enunciation "Man is just." Opposite it write its negation "Man is not just," and under these the two infinite enunciations, "Man is nonjust," "Man is not nonjust."

[[

Diagram #2 (Image 2)]]

It is evident from this table that the verb "is" whether affirmative or negative is adjoined to "just" and "nonjust." It is according to this that the four enunciations are diversified.

             15. Finally, he concludes that these enunciations are disposed according to an order of consequence that he has stated in the Analytics, i.e., in I Priorum.

             There is a variant reading of a previous portion of this text, namely, I mean that "is" will be added either to "man" or to non-man," and in the diagram "is" is added to "man" and "non-man." This cannot be understood to mean that "man" and "non-man" are taken on the part of the subject; for Aristotle is not treating here of enunciations with an infinite subject and hence "man" and "non-man" must be taken on the part of the predicate. This variant text seemed to Alexander to be corrupt, for the Philosopher has been explicating enunciations in which "just" and "nonjust" are posited on the part of the predicate. Others think it can be sustained and that Aristotle has intentionally varied the names to show that it makes no difference what names are used in the examples.
