Quaestio II: ON THE NAME

Articulus I: HOW THAT CLAUSE IS TO BE UNDERSTOOD: „NO PART OF WHICH SIGNIFIES SEPARATELY”

We now undertake, in the following three articles, to explain the definition of the name given above, which is essential and explains the generic accounts of a logical sign and the differential accounts by which a name differs from discourse, a verb, and adverbs: “a vocal sound signifying by convention” (these phrases have already been explained in the definition of a term), “without time” (this will be explained in the definition of the verb), and “no part of which signifies separately, finite, and in the straight case.”

SOME among the more recent authors abandon Aristotle on this point and say that some names are truly names even if they have parts that signify, such as equiferus, respublica, proconsul, and other compounds, whose parts truly and properly signify separately. Therefore this part of the definition is false.

THE OPPOSITE, however, is expressly stated by Aristotle in On Interpretation I, the chapter on the Noun, where he says: “In the name ‘equiferus,’ ‘ferus’ signifies nothing per se, just as in the expression ‘equus ferus.’” The Holy Doctor says the same there in lecture 4. He gives the reason, which we reduce to this form: A name says of itself one and simple concept. For if it said several, it would not be one name but several names. Therefore, even if a name is composed of parts that otherwise signify, none of them must signify separately, insofar as it exists within the name.

The consequent is proved: When words that otherwise signify are taken up to compose one name, they do not enter into the composition of that word as components that contribute one signification from their own significations; rather, they receive another imposition, distinct from the one by which they were first imposed, so that they have a signification distinct from the first one they had. Therefore, they do not compose the name insofar as they formally signify; therefore they do not signify separately, because they were imposed as conjoined and received their signification as conjoined. Hence, even if each word loses its first signification, the compound still signifies. For example, “res” and “publica” separately signified “a public thing.” They are joined in the word “respublica” and, as thus conjoined, were imposed to signify a state or common government through one simple concept. Thus neither signifies separately, nor does a name result from them separately. For it is one thing to combine words to receive a new imposition, and another to construct a complex and composite concept from their significations. When they are combined for this latter purpose, they are combined as formally signifying; but not when they are combined to signify anew some simple concept that the individual parts do not signify.

FROM THESE POINTS, THE ARGUMENT IS ANSWERED: The parts of the names “equiferus,” “respublica,” etc., signify separately. The claim is distinguished: they signify separately as it were materially and per accidens, granted; formally, denied. That is, they signify when taken in themselves, but not in relation to composing that word to which a new signification of a simple concept is to be imposed. Under this formality they are not combined as signifying and as previously imposed to signify, but as capable of receiving a new imposition, materially, as though their first imposition and signification did not obtain. For example, in the name “dominus,” the parts “do” and “minus” signify separately, but they do not compose that term as parts that separately signify.

YOU WILL OBJECT: In words such as “proconsul,” “prorex,” and the like, the signification of both parts is considered so that the signification of the name results; therefore, the prior signification formally enters into the name’s composition. The antecedent is proved: “Proconsul” is the same as “vice-consul,” where the signification of “pro” and “consul” is not lost but is rather considered so that the office of a vice-consul is signified. Therefore, they enter as signifying.

Following St. Thomas in the place cited above, the answer distinguishes the antecedent: the signification of both parts is considered as the origin and occasion for imposing the compound to have another, simple signification distinct from the first one the parts had—this is granted; the signification of a part is considered as being preserved partially within the name—this is denied.

For this, note that one thing is that from which a name is imposed, and another is what the name signifies. In imposing names, one considers the etymology and origin of some prior signification. This does not contribute to composing the name’s signification, but to originating it, because the imposer took it as an occasion to impose that signification. For example, lapis (“stone”) is said to derive from “hurting the foot”; providentia (“providence”) from pro and videntia; propheta (“prophet”) as if from procul fans; proconsul from pro and consul; respublica from res and publica. These are nevertheless distinct impositions, and one is not a part of the other, but its origin or occasion. Thus these names have their etymology from other words, but they are not composed of those words’ partial significations.

THE SECOND ARGUMENT: A complex name is truly a name and yet has parts that signify separately; therefore the phrase “no part of which, etc.” is wrongly posited. The major premise is proved: A complex term is truly a term; therefore a complex name is truly a name.

The answer denies the major premise. The antecedent of the proof is granted and its consequent denied. The difference is that in a term the account of a part is considered formally and principally: we find composite parts, as an arm is a part of a human being, yet it is composed of hand, fingers, sinews, etc. A complex term is therefore one term because it is one part, even if it is composite and complex. In a name, however, the account of a part is not principally and formally considered, but the account of the name is: namely, that it be a mark and designation of a thing, for this is why it is called a name. We use names to designate, make known, and distinguish things. A complex name, then, is not one name but several, because it is not one mark and designation but several; thus it will be one term, but not one name.

OBJECTION: An equivocal name is one name and yet signifies many things, as is clear from its definition. Therefore, even if a complex name signifies many things, it will still be a name and one name.

The answer is that an equivocal word is one name by reason of one significant vocal sound. For in concrete terms of accidents, unity of subject gives unity simply and individually, although the forms are several; just as a subject having color and heat is not several “such-things,” but one “such-thing,” as is said in Logic, question 13, article 2.

Articulus II: WHETHER AN INFINITE NAME IS A NAME

Here we explain the particle “finite,” by which we said that infinite names are excluded from the account of a name. An infinite name is “one which, when some negation is added, makes its signification indeterminate.” This is to be infinitized.

In this connection, note that a negation attached to a term can act upon it in two ways: either by passing into its signification, destroying it and substituting in its place the negation of the thing signified, which indeed applies to all subjects capable of such a negation; or by leaving its signification unchanged and removing composition or copulation, since its force attaches to the verb as it copulates the extremes. When it acts in the first way, it is said to infinitize, that is, to render the name itself indeterminate; when it acts in the second way, it is said to negate, and it makes the proposition negative. Hence this effect of negating is exercised only within a proposition, since it concerns the copula.

Hence, for a name to be infinitized, the negation must not be signified in its own right and by the very first imposition; rather, by affecting the name, it must render its signification indeterminate, that is, signifying not what the thing is but what it is not. Thus the names “no one” and “nothing” are not infinite, because they signify negation itself in its own right and directly under a determinate concept, rather than making some positive signification indeterminate by an added negation.

Second, it must be observed that an infinite name is incomplex and connotative.

The first is established by Aristotle and St. Thomas, who expressly assert it in the first book of the Perihermeneias, in the chapter on the Name. It also follows from the reasoning: an infinite name does not leave its signification in the state it had, but changes it into its opposite, namely, into the negation of what it signifies. Therefore it does not retain a double signification, the positive one it had before and the added negation—for if it retained both, it would not change the former. Therefore it is not complex, since there is no double signification in it. Hence there is no infinitization in the complex expression “no man,” because both significations remain intact. The signification must therefore be wholly changed, from a double one into a single one, and consequently be incomplex.

That it is connotative is clear, because an infinite name signifies negation not abstractly but concretely; therefore it signifies connotatively, since formally it signifies the denied form, and on the side of the subject that has it, of which it is concretely predicated. This is what it is for something to be connotative. — The antecedent is proved as follows: an infinite name is verified of something positive, but it cannot be verified if it signifies negation abstractly; therefore it must signify negation concretely and as something inhering. The minor is proved because one cannot say of a stone, for example, “A stone is the negation of a man,” but one can say, “A stone is a non-man.” Therefore, to be predicated, it must be signified concretely and connotatively.

LET THIS, THEN, BE THE CONCLUSION: An infinite name is not a name, and is rightly excluded from the account of a name by the particle “finite.”

So say Aristotle and St. Thomas here.

The FIRST PART, that it is not a name, is commonly admitted by all. It is proved as follows: infinitization removes the proper and essential function of a name; therefore an infinitized name is not a name.

The antecedent is proved: the proper function and account of a name is to be a mark and designator of a thing, as we said above. A name is so called from marking, because by each thing’s name we mark, distinguish, and designate it. But an infinite name neither marks, designates, nor names anything; therefore it is not a name. The minor is clear, because as soon as a name is infinitized, it renders its signification indeterminate and signifies only what something is not, not what it is, as can be seen in “non-man” and the like.

The SECOND PART of the conclusion, namely, that it is excluded by the particle “finite” and not by another, is disputed by some recent writers, who strike that particle out as superfluous. Yet it is explicit in St. Thomas, both in Opusculum 48, chapter on the Name, and in the first book of the Perihermeneias, lecture 5, where, treating of the infinite verb (and the same applies to the name), he says that the Philosopher first defined the verb in general and then, by these particles, excluded those things that are imperfectly verbs. Therefore a perfect and exact definition of the name and the verb requires these particles; without them—or, to speak to the point, without the particle “finite”—the proper function and mode of signification of a name are not explained: namely, signifying by way of a mark, or marking what the thing is. For this is what naming is.

Nor is the infinite name excluded by the particle “of which no part, etc.,” because, as we said, an infinite name has no parts but is incomplex. For if it were complex, a proposition with an infinitized subject would be negative, because that negation would also extend to the copula and not only to the subject, since there it would have its partial signification, which formally and significatively composes the proposition and, contrary to its nature, would destroy everything it encountered after itself. But the consequence is absurd, as is evident in conversion by contraposition, which proceeds from a negative proposition to an affirmative one with infinitized terms. Therefore, and so on.

OBJECTIONS ARE ANSWERED.

First you will object: An infinite name is truly a term; therefore it is truly a name.

The antecedent is proved: it is an extreme and a part of a proposition, as is clear in “A stone is a non-man”; therefore it is a term. The consequent is proved from St. Thomas, first book of the Perihermeneias, lecture 1, who says that every proposition must consist at least of a name and a verb, since these are its principal parts. Therefore, if a genuine proposition is formed from a verb and an infinite name, the infinite name truly is a name.

It is confirmed: a verb that serves as the copula in a proposition truly is a verb; therefore a name that is an extreme copulated or capable of being copulated truly is a name. For just as it belongs to the account of a verb to be a copula, so it belongs to the account of a name to be an extreme capable of being copulated.

The argument is answered: The antecedent is granted and the consequent denied. For to be a term, it suffices to be a part in some way; but to be a name, it must be a part by way of a mark, or of marking what the thing is. An infinite name does not have this.

To the proof from St. Thomas, it is answered by explaining the proposition “Every proposition must consist of a name, etc.”: that something acquires the status or property of a name intrinsically and in its own right, or by accommodation and accidentally, is granted; that it is intrinsically and strictly a name is denied. For many things are placed in a proposition as extremes—not because they are names, but because they are put in place of a name or are taken in the force of a name—as St. Thomas says in the present lecture 5 and in Opusculum 48, chapter on the Verb. Thus one might say, “To run is to move,” “yesterday is not today,” or “quickly is not slowly.” These expressions acquire a certain use as a name through the accommodation of the intellect, not through the proper character of their signification, but only accidentally; and thus they form a proposition. The same is said of an infinitized name.

To the confirmation it is answered: the antecedent is granted and the consequent denied. The difference is that for something to be a verb, nothing more is required than that it signify by copulating, or by way of a copula; for this is the proper function and office of a verb, so that if it has this, it truly is a verb. A name, however, does not merely have to be an extreme capable of being copulated; it must also be so by way of a mark, or of marking. An infinite name does not have this, and therefore is not a name.

Second argument: An infinite name signifies something certain and determinate on the side of its formal signification, although it signifies indeterminately on the material side and as regards what it connotes; therefore it truly is a name.

The consequent is clear, because each thing, in order to be or be called this or that, must be judged according to its formal character, which is primary and specificative in it, and not according to its material or connoted character. The antecedent is proved because “non-man,” for example, signifies a determinate negation, namely, of man and not of horse, just as “blind” signifies the negation of sight and not of hearing. Therefore, just as “blind” truly and properly is a name, so too are “non-man” and the other infinite names.

It is confirmed: “intelligible” and “imaginable” signify something indeterminate, just as “non-man” does. For they are said both of what is and of what is not, both of real beings and of beings of reason, and yet they truly are names. Therefore, the fact that an infinite name signifies something indeterminate should not exclude it from the account of a name.

A second confirmation: transcendent or supertranscendent names can be infinitized by adding a negation, just like other names; and yet when so infinitized they truly remain names. It is proved as follows: “non-being,” for example, when so infinitized, either signifies something or nothing. If it signifies nothing, then it does not signify, and so it is neither a term nor a name, but falls away from its signification through the added negation. If it signifies something, then it signifies being; and thus “non-being” would signify being, which is contradictory.

The argument is answered: The antecedent is distinguished: that an infinite name signifies something certain and determinate on the side of the thing signified is granted; that it does so by its mode of signifying is denied, and the consequent is denied. For to be a name, it is neither sufficient nor necessary to signify a certain and determinate thing; rather, it must signify in a certain, determinate, designative, certifying mode, by way of a mark.

To the proof: “Non-man signifies a determinate negation” is distinguished: on the side of the thing signified, granted; by a determinate mode, as if marking and designating, denied. In this connection, note that signifying something determinate can be understood in two ways: either on the side of the thing signified, that is, signifying a determinate thing; or according to the mode of signifying, that is, in a mode that designates what the thing signified is. For something to be a name, it is not required that it signify something determinate in the first way. However indifferent and common something may be—even negation itself, or “intelligible,” “imaginable,” or “being”—if it is signified in a designative and marking mode, that is, one that says what the thing is or how it is, it will be a true name. But if it signifies a determinate thing in an indeterminate mode, one that does not designate or mark what it is, but rather what it is not, it will not be a name, because it lacks the function and office of a name, which is to name or designate; for by naming we distinguish and designate one thing from another. Nor is something judged to be a name solely by the thing signified, but also by the mode, which belongs to the formal signification and distinguishes a verb from a name: a verb signifies in one way, a name in another, although they signify the same thing, as “I run” and “running” do.

Hence the answer to the proofs and confirmations is clear. Although “blind” signifies the negation of sight, it signifies as if marking and designating what something is, not what a form is not, as “non-man,” “intelligible,” and “imaginable” do: these signify the most indeterminate things, but in a determinate mode. — To the final proof, the minor is denied. To the proof that “non-being” either signifies something or nothing, it is said to signify the negation of being, not in a determinate and designative mode that says what the negation of being is, but by saying what is not. Therefore, “non-being signifies something” is distinguished: insofar as it is signified by the infinitized name “non-being,” it is denied, for in that respect it signifies precisely the negation of being in an indeterminate mode. Insofar as, through reflexive cognition, that negation of being can be cognized in the manner of a being and become a being of reason, it is granted; for then it will signify a being, or something of reason, not by the name “non-being,” but by another name signifying that reflex concept of non-being in the manner of a being, for example, “a negation of reason” or “a being of reason.”

Finally, it is argued: An infinite name has parts that signify separately; therefore it remains excluded from the account of a name by the particle “of which no part, etc.,” and is not excluded by “finite.”

The antecedent is proved: “non-man” consists of “non” and “man”; but “non” composes the infinite name not materially, but significatively and according to its ultimate concept. Therefore the name is subordinated to a concept different from the one it infinitizes, and consequently to a double concept, and it is complex. The minor is proved: the infinitization of the expression “non-man” does not come from the material sound of the word “non,” but from its most formal signification; for if “non” does not signify, it removes or negates nothing. Therefore it infinitizes by signifying and not merely by composing materially.

The answer is, as was said above about “republic,” “proconsul,” and so forth, that in an infinite name, as in names of composite form, there is both the derivation of one name from another and composition. If we attend to derivation, it is certain that the signification of “non-man” was derived from the signification of “non.” If we attend to composition, “non” and “man” are related materially in the expression “non-man”; nevertheless, the infinitization that impedes the name’s positive signification originates and proceeds from the signification of “non” and “man” derivatively and efficiently, not compositionally and formally. Therefore a new imposition and signification is given, according to which the infinite name is subordinated to a single concept and signifies the negation of man concretely, since the lack of names leaves us without simple words to signify it. Thus, in infinitization, “non” is not a negation of just any kind, but a negation that changes and impedes the name’s signification.

Articulus III: WHETHER OBLIQUE CASES ARE RIGHTLY EXCLUDED FROM THE ACCOUNT OF THE NAME

In explaining the definition of a name, we said that the word “straight” is included to exclude oblique cases. That these are not names is clear from Aristotle, On Interpretation I, the chapter on the Noun and the Verb, because the proper account and function of a name is to signify directly by naming in itself; oblique cases do not signify in this way. Therefore, they are not names.

The major premise is clear from the etymology of “name.” The minor premise is proved as follows: to signify something by naming is to signify it as if by noting and designating what it is in itself. But the cases “whose” and “to whom” signify a thing as belonging to another, not in itself and per se. Therefore, they are not names; rather, they are called cases because they fall away from the proper account of a name. Hence Aristotle and St. Thomas, in the same place, lecture 4, also assert—

[Lacuna: Reiser p. 223 is missing from 259-270.pdf; in its place the leaf numbered 233 is bound in, which belongs to On the Discourse*. The text resumes on p. 224.]*

Likewise, oblique cases differ from the straight case only through a different exercise of the very same representation; they do not add a different representation.

THE REPLY: The antecedent is granted and the consequent denied. The difference is that some modes function only as an application of a concept, while others function as an explication of a concept. The former do not arise from a different way of understanding or representing a thing, but from the application and use of the intellect, insofar as, by understanding a relation of one thing to another, it applies and joins one to the other in different ways. Such are the relation of predicate and subject, the difference of supposition, and the like. Truth and falsity similarly arise from whether a thing is or is not. Thus, when a thing exists, truth arises in the statement; when it does not exist, falsity arises, while the statement itself remains unchanged, as Aristotle said in the chapter on Substance, because the representation need not change; rather, the object’s existence changes, so that a different relation of conformity or nonconformity to it results. In the same way, from the object’s co-existence with cognition, intuitive or abstractive cognition arises without a new representation (according to the probable opinion). Thus, the modes cited in the argument are only applications of a concept, and so they do not vary it in its representation. But the mode of obliqueness, which a future or past tense in a verb, or “what,” “whose,” and “to whom” in a noun, imports, pertains to a different way of understanding one and the same thing, as the cited Holy Doctor says in the Quodlibet. Something is understood in the straight case as a person or thing acting, and in the oblique as something acted upon or as connoting the being of another. These are different modifications of the representation and of the represented object, arising from different ways of understanding it. For the relation of an acting, possessing, or undergoing person—“by whom” or “to whom”—is not signified as a thing, but as a mode of a thing, which is signified now as “from which,” now as “to which,” etc. A concept is therefore produced under that different mode of explication. Thus this is not mere application, but explication and a different representation.

THE SECOND ARGUMENT: Oblique cases vary the intrinsic representation of a concept; therefore, they differ categorematically from the straight case, contrary to St. Thomas’s first statement.

The consequent is proved: categorematic distinction, and distinction in the account of a term, is had through a different mode of expressing one and the same thing. For example, “I run” and “running” signify the same thing; nevertheless, one does so in the mode of something flowing, the other in the mode of a noun or something standing per se, so that one is a noun and the other a verb. The same can be seen in finite names, since they differ categorematically from infinite names.

A confirmation: “white” and “whiteness” differ categorematically by the absolute and the connotative, because although they signify the same thing, they differ on the side of what is connoted or substituted. Therefore, “whose” and “what” will all the more bring about categorematic diversity.

THE REPLY: The consequent is denied. In proof of it, the antecedent is distinguished. If categorematic distinction is had through a different mode of expressing the same thing, so that the difference is only on the side of signification, the antecedent is denied; if it is a difference on the side both of signification and of the thing signified, the antecedent is granted. Oblique cases, however, retain the same thing signified and only make oblique the mode and relation in which it is understood; therefore, they do not differ categorematically. Infinite names, on the other hand, transfer a name to another thing signified, namely, to the negation of its positive form, and so they differ categorematically on the side of the thing signified.

In reply to the confirmation: the antecedent is granted and the consequent denied. The absolute and the connotative, the common and the singular, differ through a mode of signifying attributed to the thing itself, which modifies the thing signified in itself. For example, a thing as absolute or with a connotation, in the mode of something adjacent or standing per se, imports in some way a diversity in the thing. Oblique cases, however, only express a different mode of consignifying that pertains to a certain deficiency of the noun itself insofar as it is a noun: the noun signifies a thing in such a way as to note or designate what it is, while an oblique case signifies that it belongs to or is for someone. This varies the mode of consignifying the thing in the account of a noun, and pertains to the mode of consignification, not to a mode that affects the thing in itself categorematically. For such a mode can also be designated through the nominative case and not only through an oblique case, as is clear in examples concerning the common, the connotative, the absolute, and so on.
