1. The Opinion of Henry of Ghent

192. [Exposition of the opinion] - Here it is said [sc. by Henry] that every relation is the same as its foundation - look at his Quodlibet 9 q.3 and 5 q.2 (which seem as it were to be contrary).

193. For this opinion multiple arguments are given:

First, that relation is transferred to God according to the proper idea of relation, and therefore there are said to be two categories properly in divine reality, namely relation and substance [1 d.8 n.130]; but if it were going to be of the idea of relation that it would be a different thing from its foundation, then in God there would be thing and thing, which is against divine simplicity.

194. And from this middle term, namely from simplicity, a general argument is made: for a ‘like white thing’ is not more composite than a white thing simply, and consequently the relation of likeness does not add anything different from the foundation; therefore neither is relation a different thing.

195. Secondly this point is argued by way of change, that if relation were a different thing from the foundation, then whatever foundation it would come to de novo would be changed - which seems to be denied by many authorities; first of the Philosopher Physics 5.1.225a34, who denies that there is motion or change in the category of relation; second of Boethius On the Trinity ch.5 (look at him there [not expressis verbis but implicity]); third of Anselm Monologion ch.25.a

a.a [Interpolation] from Boethius On the Trinity: negative and relative predicates make no composition (look at him there); third of Anselm, Monologion, “For it is clear that for a man after a year...”

196. Third an argument is made from this, that if relation were a thing different from its foundation then likeness would have its own presence in a subject different from the presence in it of whiteness; and this seems prima facie unacceptable, because a relation founded on a substance (if there is any) would be accidental because of its own accidentality - which seems against Simplicius On the Categories (f. 95r, 40v-41r) where he says that the Philosopher treats of quantity and quality before relation because relation is founded immediately on these; and it is not founded on substance immediately (and this when speaking of accidental relation), because relation founded on substance does not have a proper accidentality of itself.

197. The same preceding inference [n.196] is also proved to be unacceptable because then the genus of relation would not be simple but as it were composed of ‘in’ and ‘to’ - which seems unacceptable because the first concept of any first genus should be altogether simple, as it seems;     therefore etc     .

198. Fourth it is argued that if relation were a thing other than the foundation, then there would be an infinite regress in relations; for if this relation is a thing other than the foundation, by parity of reasoning the otherness too (which is a certain relation) will be a thing other than the foundation, and this otherness a thing other than the foundation, and so on ad infinitum; but this is unacceptable,     therefore etc     .

199. Fifth thus: relation does not have a distinction in its species save by reason of the foundation (for lordship is not distinguished from paternity by the fact it is ‘in relation to’ but by reason of the foundation - nor are these disparate relations distinguished, nor are they the same as relations of equivalence, save by reason of unity and difference of form in the foundations [n.205]); but if relation were a thing other than the foundation, it would have of itself formally a distinction in its species;     therefore etc     .a

a.a [Interpolation]: Again, if likeness in this thing [sc. one of two things alike in whiteness] is other than the whiteness in it, by parity of reasoning the likeness in the other term [sc. the other white thing the first white thing is like] is also other than the whiteness in it; therefore both foundations can be together without this likeness or that, as things prior in nature can be without things posterior in nature; and so two white things can be together and not two like things - which seems incompossible, because likeness is unity in quality.

200. [Rejection of the opinion] - Against this opinion I argue first as follows: nothing is the same really as anything that it can, without contradiction, really be without; but there are many relations that foundations can, without contradiction, be without;     therefore there are many relations that are not the same really as their foundation.

201. Proof of the major: because that the ‘same being’ should really be and really not be seems to be opposed to the first principle [sc. the principle that the same thing cannot both be and not be at the same time etc     .], from which first principle the diversity of things seems at once to be inferred; because if contradictories are said of certain things, these things seem not to be the same in the way that the contradictories are said of them, and so if the contradictories ‘to be’ and ‘not to be’ are said of them, they seem not to be the same in being or in reality, or not to be the same being.

202. There is confirmation of this, because if the major [n.200] is denied, there seems no way left for being able to prove the distinction of things; for it will be said by the impudent not only that the several natures in one supposit - as substance and accidents - are the same, but also that Socrates and Plato are the same, or that Socrates and stone or white do not really differ; and if it be argued against him that ‘Socrates can exist when a stone does not exist’ and if from this the distinction of one from the other is inferred, or if it be argued that ‘Socrates can exist and not be white’ and if from this the distinction of subject and accident is inferred - the consequence will be denied, because the impudent will deny the proposition [sc. the major, n.200] on which these consequences rely, which proposition you also deny [sc. ex hypothesi from the beginning of this paragraph].

203. This proposition too, ‘those things, one of which can persist without the other, are really distinct’, will be denied by the impudent. But once it has been denied, the whole doctrine of the Philosopher perishes, Topics 7.8-9.154a23-55a38, whereby he teaches that a proposition or problem is easily destroyed by discovery of its contradictory but is with difficulty established; but if this proposition [sc. at the beginning of this paragraph] is denied, no proposition or problem seems able to be destroyed (because if it is not destroyed by a contradiction then not by any other opposition either), or at least it seems not able easily or very easily to be sustained - because no place [sc. of argument] according to or assigned by Aristotle seems efficacious for destroying anything if this place is destroyed.

204. On this way of the philosopher is also founded the way of motion or change for proving a distinction - the way that the philosopher uses when proving that matter is a thing other than form, because it remains the same under opposed forms; the Philosopher also uses it, in Physics 5.2.220a1-11,a to prove that place is other than the things placed in it, because the same place persists along with different things placed in it.

a.a [Interpolation from Appendix A] Averroes com.3 and more manifestly in com.7 says, “If place is prior to any natural body (as Homer posits), then there could be place without body, and the place would not be corrupted on the corruption of the body.” See there.

205. The minor [n.200] is also plain in all relations whose foundations can exist without terms, as is the case with all relations of equivalence (as are similar, equal, and the like); for if this white exists and that white does not, this white is without likeness -and if that white should come to be, there is likeness in this white; therefore this white can exist with it and without it. It is similar in the case of many relations of nonequivalence; for if this man exists and he is such that no one else is subject to his power, he will be without lordship - and again he can be a lord with the accession of slaves, as Boethius says [On the Trinity ch.5]; and so it is in many other cases, about none of which is there need to adduce examples.

206. This reason [n.200] is also confirmed as to the whole of itself (because the following confirmations are valid for both the major and the minor); for if a relation is not other than its foundation, which yet remains in the relation’s absence, the incarnation seems to be denied, and the separation of accidents from the subject in the Eucharist; also every composition in things seems to be denied, and all the causality of second causes.

207. Proof of the first unacceptable result [sc. about the incarnation]: if the union of human nature with the Word is the same really as the human nature, then if the Word had never assumed that nature and made it, the same nature, absolute, then it would really have been united with the Word as it is now, because the whole reality of the assumption was assumed; also if the Word put aside the nature (while the nature itself remained in itself the same), the nature would remain really united with the Word and as really as it is united now, because the whole reality of the nature would then be preserved as it is now.

208. The proof also of the second unacceptable result [n.206], about the Eucharist: that if the same quantity of bread remains (the same as was before), and if the inherence of the Eucharist in the bread is nothing other than really that very quantity, then the Eucharist is really united to the bread (or informs it) now as before.

209. Proof of the third unacceptable result [n.206, composition in things]: because if a and b compose ab, and if the union of these parts with each other is nothing other than absolute a and b, then when a and b are really separate the whole reality remains that belongs to a and b united. And then a and b when separated remain really united and so the composite remains when the components are separated, and so the composite will not be composite - because when the composite remains while the component parts are separated, it is not composed of them; for then nothing would remain but a one by aggregation, as the Philosopher seems to conclude in Metaphysics 7.17.1041b11-19.

210. Proof too of the fourth unacceptable result [n.206, about the causality of second causes]: because whatever is caused by diverse second causes requires in them first a due proportion and coming together so that it may be caused by them; but if this coming together and proportion are only something absolute, then the causes are in this way really causative of this sort of effect when they do not come together just as when they do, and thus they can when together really cause nothing that they cannot cause even when not together; for when no other reality is posited, no thing can be caused that could not have been caused before. And thus could one have argued in the case of the third member, about the composite parts [n.209], because if a and b when separate do not compose ab, then neither do they do so when united, because just as the same thing -without any other reality - cannot cause something now which it could not cause before, so neither can the same things without any other reality compose now something that they could not compose before;     therefore etc     .

211. Seconda principally I argue against the aforesaid position [n.192]: nothing finite contains, according to perfect or virtual containing, opposites formally (because however much in God is conceded a most perfect containing of all perfections by identity that are in him, yet he cannot contain absolute opposites formally in himself, although he could have in himself such opposites virtually and such relatives formally - but from this is conceded an infinity of the foundation). But equality and inequality are opposites formally, and similarly likeness and unlikeness - at any rate relative to the same correlative term; but these can be perfectly founded on the same foundation successively. Therefore the foundation contains neither of them formally (or, more to the point, really and by perfect identity), because the reason for its not containing both is the same as the reason for its not containing either.

a.a [Interpolation from Appendix A] This reason is doubly deficient: first because the major is false of divine relations, second because the first part of the minor is false, save when making comparison to the same thing; thus there are two false premises. However the major holds the difficulty by adding to the subject the ‘nothing finite’     etc . - The minor is true when comparing equality and inequality to the same thing, and thus both are in the same foundation, though successively.

212. Third thus: the same thing does not contain many things of the same idea the same in perfect identity with itself; but many relations of the same idea are in the same foundation, as there are many likenesses founded on the same whiteness; therefore      etc. The major is plain inductively in the case of everything that contains many things by identity, because one containing thing contains one thing of the same idea.

213. Fourth thus: that which contains something by identity entails too, if it is more perfect, that what is contained in it is more perfect by identity (as a more perfect soul has a more perfect intellect - and according to those who posit that the same form is intellective and sensitive, and of corporeity and of substance, the intellective form includes a more perfect sensitive form than is the sensitive form in brutes); but a more perfect foundation does not contain in itself a more perfect relation, because not every whiter thing is more alike, as is manifest to the senses;     therefore etc     .

214. Fifth thus: things contained in something by identity are not less different if the containers of them are more distinct; but relations founded on two genera are less different than two relations founded on a thing of the same genus (nay on the same most specific species), because equality, which is founded on quantity, and likeness, founded on quality, are less different than likeness and relation of active power, which can be founded on the same heat;     therefore etc     .

215. Sixth and last thus: a relation of reason is a thing of reason different from its foundation, therefore a real relation too will be a real thing different from its foundation. The proof of the consequence is that, just as a relation of reason is the mode of the object in the first act of the intellect, and yet it is in itself not nothing in the genus of intelligibles but is in itself something truly intelligible (although it is not as or equally first as that of which it is the mode, since it is only understood by a reflex act - and so it is not as perfectly understood as that of which it is the mode), so too a real relation, although it is a mode of its foundation (and not equally first with it, nor as equally perfect as it), yet in itself it is a thing, because what is in itself nothing is the real mode of nothing; for there is no more general name than being or thing (according to Avicenna Metaphysics 1.6, f. 72rb), and so that to which being or thing do not belong has no real being belonging to it.

216. Further, the conclusion - for which these reasons have been adduced [nn.200-215] - is proved by authorities:

And first from Augustine On the Trinity 5.5. n.6, “In the case of created things, what is not spoken of as substance is left to be spoken of as accident;” here he expressly maintains that relation is an accident in creatures. Although this does not have to be understood of the relation that is of the creature to God [cf. nn.253-54, 260-63, below], yet it is certain that it holds, both in truth and in his intention, of the relation that can be lost while the foundation remains.

217. Again, Ambrose On the Trinity 1.9 nn.59-60, “If God existed first and later the Father, he has changed by the accession of generation; may God ward off this madness.” Therefore by mere accession of real relation a change could be made in a divine person, according to Ambrose - and this would not be unless that relation was a thing other than the foundation, because the foundation was there beforehand.

218. Again, Hilary On the Trinity 12 n.30, “That what was is born is already not only to be born but to undergo change by being born,” and he is speaking of the nativity of the Son of God. Therefore ‘to be born’ states a new relation.

219. Again, the Philosopher in the Categories 7.6136-37 says, “Relatives are all things that are said of others or exist to others as to what it is they are,” - and by this reasoning are substances excluded, which, although they are ‘of others’, are yet not ‘to another’;     therefore the ‘as to what it is they are’ is taken here, not for existence in the intellect, but for existence in reality. But if relations in reality are of others ‘as to what it is they are’, and a foundation is not of another ‘as to what it is’ - then the being of the latter is one thing and the being of the former another thing; therefore etc     .

220. Again, Simplicius On the Categories ‘Relation’ (f. 43r) declares expressly that relation is to another.

221. Again, the Philosopher Metaphysics 12.4.1070a31-b4 maintains that as the categories are different so also are their principles - and he exemplifies it specifically of the distinction of relation from other categories and of the distinction of the principles of relation from the principles of other categories..

222. Again, Avicenna Metaphysics 3.10 (f. 83va) seems to maintain expressly that relation has its proper certitude; and at the beginning of the chapter he maintains that it has, according to its certitude, its own presence in things and its own accidentality.
