From Categories as Enemy to Categories as Friend

 

There has been quite a bit of interest in the early reception of Aristotle lately, and particularly in the way that those who embraced Plato saw him. Lloyd Gerson has written a powerful book examining Neoplatonist theories of the harmony of Plato and Aristotle, in which he strikes significant blows against the modern Anglo-American orthodoxy that assumes a wide gulf between Aristotle and his philosophic mentor.[1] Now we have also got the useful, though patchier, account by George Karamanolis of the reception of Aristotle by Platonists from Antiochus of Ascalon to Porphyry.[2] A significant difference between the two books results from a certain consensus of Neoplatonists to the effect that Aristotle was an ally, as opposed to the radical disagreement among platonically inclined philosophers before Plotinus as to whether Aristotle ought to be afforded any credibility at all. From Iamblichus in the late 3rd or early 4th century Aristotle supplied the early part of the philosophic curriculum that any budding Platonist could be expected to tackle, and from AD 529 (and probably for some time before at Alexandria) it became the politically astute option (if not the only one)[3] to give greater prominence to one’s Aristotelian studies. However, I know of no evidence that the reading of Aristotle ever featured directly in any Platonist curriculum before Plotinus, and even there it was less an educational text than a basis for discussion within an educational circle. Not until Porphyry do we find a Platonist producing a commentary-like work on an Aristotelian text, and Porphyry was sufficient of a scholar to comment on other non-Platonists from Homer to Ptolemy.[4] Admittedly we have some evidence of hermeneutic works on the Categories before the end of the first century AD, from figures such as Eudorus, Lucius, and Nicostratus, but these works were certainly not commending Aristotle’s teachings and using them as a basis for positive lessons.[5] Somehow Platonists came to appreciate the didactic potential of the Aristotelian organon in particular. No work became more important than the Categories. It is perhaps worth asking ourselves how this fundamental change came about.

            To begin with I think that one should clarify what one means by a ‘Platonist’. Karamanolis would seem to define the term broadly, but at the expense of casting the net far too wide. The concept of  ‘Platonist’ simply is not around in the days of Antiochus of Ascalon, who for him is the beginning of a pro-Aristotelian Platonism. His assumption neglects the fact that Antiochus thought of himself as a follower of the ‘Old Academy’ together with Aristotle and at least Zeno from the Stoic school. It was simply a single type of philosophy, drawing upon the common notions that all sensitive human beings share, and using rather different language to interpret them. The message was the same. Antiochus was not an eclectic, since he did not acknowledge that he had to choose between the key players; he was just a philosopher of the classical type. So far as we are aware nobody called themselves a ‘Platonic’ philosopher until the late first century AD. Eudorus, it seems, was content with the term ‘Academic’ and Plutarch’s writings strongly suggest that this term would have suited both him and his mentor Ammonius. In any case he was like many other prominent intellectuals of the age in not requiring a living from philosophy; for such persons a fluid allegiance remained entirely possible. Only the teacher of philosophy needed to embrace a single philosophic system and defend it against its competitors, and only he had to choose carefully how he would describe himself. Karamanolis likewise has no problem about seeing Numenius as a Platonist, even though it is clear enough that this was not how he preferred to describe himself. He was a ‘Pythagorean’, who happened to believe that many works of Plato largely preserved Pythagorean doctrine. On the whole those on the boundary between Pythagoras and Plato were not easily going to find Aristotle to be an important ally, even if this was to change with the early Neoplatonists.

            By contrast I am only considering those who seriously engaged in the interpretation of Plato, and thought of their primary allegiance as being to the Platonist cause. Antiochus, who does not engage in serious hermeneutic issues, should be excluded; Eudorus of Alexandria may possibly have called himself an ‘Academic’ in a sense that implied a primary allegiance to Plato and cannot easily be ignored, but otherwise I shall confine myself to figures who could without hesitation be described as ‘Platonics’. It is important that those we examine should all feel a primary allegiance to Plato, and should have been confronted by the challenge of determining a proper Platonist response to Aristotle in general and to his Categories in particular.

            Recent scholarship on Platonic hermeneutics in this period has clearly revealed just how difficult it was for Platonists to be able to interpret Plato’s own writings, given the absence of strong interpretative traditions and agreed hermeneutic principles. It was little wonder then that framing their response to Aristotle was an even more difficult challenge. Long known primarily from his exoteric works, Aristotle in a post-Andronicus era had to be re-assessed on the basis of exoteric as much as esoteric texts. It was no easy matter to be reconciling the Eudemus, that not only argued for the existence after death of the intellect but actually seemed to assume the continuity of some rudimentary memory upon the resumption of bodily life, with the concept of the soul as eidos and morphê of the physical body at the beginning of the second book of the De Anima. Then again, there were quite enough interpretative challenges within the esoteric treatises themselves, such as reconciling what is said about ousia in the Categories with what is said about it in Metaphysics Z. Analogous problems were felt with regard to Plato, by whom sense-objects could be described both as on and as mê on according to the pro-Thrasyllan source of D.L. 3.64. Plato was hard enough, but at least Platonists had to seem to be in agreement with him. Aristotle often presented much the same challenges, and it was open to them to embrace or dismiss what he said as they pleased.

            At this point I think that we have to distinguish sharply between Platonist attitudes to the Aristotelian categories themselves and to the work in which they spelled out. For instance, the anonymous Theaetetus-commentator (LXVIII) is happy to find the first three Aristotelian categories behind the text of Theaetetus 152d: ousia, poson, and poion. But he is not so much acknowledging a debt to Aristotle as claiming to find in a Platonic text many of the concepts that are fundamental to Aristotelian theory here. This is even more obvious in Alcinous, when he claims in chapter 6 (158.43-4) that all ten categories (he does not call them ‘Aristotelian’) are to be found in the Parmenides and other writings. The primary legacy of the Categories is embraced, without any obvious endorsement of the work itself. This may be important given that chapter 5, which gives ontological primacy to the physical particular, is one of the seemingly most anti-Platonic texts of the Aristotelian corpus—at least for those who see a theory of transcendent ideas as being the heart of Platonism. Where we see Platonists of the period attacking the Aristotle on the categories it generally involves an attack on the work itself; where we see the embrace of the categories themselves there is no admission that the Aristotelian work is covering new ground. Plato may either have anticipated Aristotle’s ten, as in Alcinous, or have employed a different set that better meets philosophy’s needs.

At this point it is worth recalling that according to Dercyllides, a figure somehow linked with Thrasyllus and highly regarded by Theon of Smyrna, the Old Academic figure Hermodorus had attributed three categories to Plato: ‘in itself’ (kath’ hauto), and two kinds of ‘in relation’ (pros hetera), one of which involved its relation to its opposite (pros enantia as opposed to the simple pros ti). If this information was well known among Platonists of the early empire, then it may have placed them under some kind of pressure both to find categories in the dialogues and to demonstrate that they serve their purpose better than Aristotle’s. The basic division suggested by the report was suggested both by Sophist 255c-d and by many passages of the Parmenides from 136a. It is supported by Xenocrates too.[6] Finding a distinction between the simple pros ti and the pros enantion in Plato would have been more difficult, but one could certainly find examples of the latter in the Parmenides (e.g. 152d6). It is likely that Dercyllides had appealed to Hermodorus’ authority with a view to reviving these ‘categories’ and finding something distinctively Platonic rather than Aristotelian or Stoic.

The three Platonically-inclined philosophers whom Simplicius cites for their hostile attitude to the Categories are Eudorus, Lucius, and Nicostratus. Eudorus presents a considerable challenge, as it is very difficult to build a coherent picture of him from the varied fragments that we possess. We know him as one who engaged also in the interpretation of Plato and Pythagoras, to both of whom he is well disposed.[7] He is described as an Academic, which in my view means that he resembled Plutarch in being committed to a broadly Platonic philosophy, with a nod towards the critical activities of New Academy as well. Eudorus came at a time when Aristotle was being re-marketed as the author of the treatises. The efforts of Antiochus of Ascalon to show that Platonism and Aristotelianism were one and the same philosophy seemed plausible enough as long as Aristotle was known primarily from the ‘exoteric’ works, but, whatever the truth behind the story of the rediscovery of the treatises, there was certainly a new wave of interest in them, involving Andronicus, Boethus, Aristo, and Athenodorus as well as Eudorus.[8] Two former followers of Antiochus of Ascalon’s school, Aristo and Cratippus,[9] were led to declare themselves to be Peripatetics, presumably after (i) recognizing that Aristotle did differ from Plato in spite of what the exoteric works might suggest, and (ii) finding on reflection that they preferred the mature Aristotelian position. I wish to emphasize here that the treatises do not only reveal an Aristotle who cannot without ingenuity be reconciled with Plato; they also indulge in extensive criticism of positions adopted by Plato, Speusippus and Xenocrates in matters that range from the practical (ethics and politics) to the theoretical (metaphysics and physics) This criticism highlights above all aspects of Plato’s thought and the thought of his successors that were not grounded in the familiar sensible world. Furthermore they serve to suggest links between Plato and the Old Academy and the Pythagoreans, links that would not have been evident without Aristotle’s personal contribution. Hitherto transcendent or Pythagorizing elements may have been dismissed as metaphor and their radical nature failed to register. When the treatises began to attract attention both the transcendent leanings of Plato and the Aristotelian emphasis on the world of physical particulars became evident. The single Platonic-Aristotelian-Stoic system of Antiochus had to disappear, built as it was upon a flawed history of philosophy. Ironically it was in this new era that the first philosophy to describe itself as ‘eclectic’ was born—Potamo of Alexandria (D.L. 1.21) really did recognize that on any given issue one had to choose between the doctrines of Plato, Aristotle, and the Stoa, and that an amalgam of classical and early Hellenistic doctrines could be marketed as something new.

It is a reasonable supposition that Eudorus too recognised the extent of the differences, and was led to resist the new Aristotelian force in philosophy in favour of a Platonism that leaned towards transcendence and Pythagoreanism. We find in him an interest in transcendence, mathematical principles, and the Pythagoreans that is absent from our evidence for Antiochus. Since he embraced the side of Plato that Aristotle had repeatedly rejected, it is inevitable that he would have treated Aristotle as suspect. However, he was not alone in lacking the hermeneutic devices to see Aristotle in a particularly favourable light. Just as the interpretation of Plato was an extremely difficult task in the early days of serious interpretation, so too the Aristotelian treatises repeatedly offered some excruciating challenges for anybody committed to finding a single coherent Aristotelian position. Works and parts of works seemed to disagree. One could not easily make it one’s task to tackle just one work at a time (as one might the Phaedo, for example), since treatises lacked the internal coherence that would be required and often stood in close relation to others. It is virtually certain that the organon attracted a great deal of interest, insofar as it gave something lacking any explicit treatment in the writings of Plato. Much that was said in the works on logic was potentially helpful to a Platonist, and offered the kind of instruction that one would not think wasted on any respectable student of philosophy. So should a Platonist adopt them as something that was a natural product of Plato’s school with which Plato would agree? Should he in fact argue that Plato actually anticipated all this in one work or another? Or should he expose weaknesses in what Aristotle offered and try to work towards something more plausibly Platonic?

The centrality of the Categories to modern Aristotelian endeavours should not obscure the fact that it is rather a fiendish work to interpret. To begin with the author does not set out by defining its subject matter. The name suggests that we shall deal with the ten categories, but we are plunged straightaway into a discussion of homonyms and synonyms, before noting some basic points about predication. Chapter 4 finally introduces the ten categories themselves, but it does not do so in the order in which Aristotle will tackle them, and it does not commit him to tackling them all either. Above all, we do not receive any guidance as to whether we should be reading anything metaphysical into what we are being told, or whether we are dealing strictly with the meaningful terms that constitute sentences. Here it should be appreciated that the Stoics had long built language into the fabric of the world, while Platonists too were used to assuming that the world of language somehow reflected the realities of the universe. The precise relation may have been difficult to pinpoint, but somehow dialectic had to serve as a science for an approach to reality. Divisions and definitions were also supposed to reflect reality. So how could they easily accept that the Aristotelian Categories was a metaphysically neutral document? In particular, how could they not suspect an anti-Platonic agenda behind the identification of primary ousia with individual particulars, while universals were called ousia only in a secondary sense? And as soon as they allowed something metaphysical here, how was it to be reconciled with Aristotle’s own Metaphysics Z?

It is against this background that we should see the activities of Eudorus. We hear of him nine times in Simplicius’ magnificent Commentary on the Categories, all in the treatment of Categories 7-8, where Aristotle is dealing with Relative and with Quality respectively.[10] This probably indicates that Porphyry, to whose full-length commentary we owe most of the early material,[11] only used anything by Eudorus in this section, and possibly also that Eudorus had written either on Relative and Quality alone (as Boethus had written on the Relative, 163.6) or with a special focus on it—for he had been especially keen to show the priority of Quality over Relative. In any case Eudorus is clearly going well beyond casual criticism of Aristotelian trends, writing rather with the intention of undermining much of the detail of Aristotle’s book. Eudorus asks, not without some point, why it was that Aristotle tackled to pros ti without paying any attention to the concept of to kath' hauto to which it is opposed. Simplicius is fairly dismissive, but it does seem rather like discussing the concept of altruism without a mention of selfishness. One needs to know what else is possible. But it is certainly relevant that kath' hauto had been regularly contrasted with pros ti in Platonic and Old Academic thought.

There are times, however, when Aristotle feels the need to be especially precise, as when he says that the wing is properly pros pterôton, not pros ornin (6b36-7a5), so that there is this reciprocity even when there appears not to be. Here Eudorus is, I believe, almost satirizing Peripatetic precision when he objects that the reciprocity is now between what is spoken of in activity and what is spoken of in potency. Presumably, on the analogy of the soul, the wing is the first entelechy of a potentially winged creature, and Eudorus claims that pterôton is used to refer to any member of species whose adult has wings, while epterômenon is used for anything whose wings are actually formed. It is no accident here that Eudorus is given the title Akadêmaikos, since he appears to be giving a critique of Aristotle in Aristotelian terms as a New Academic would have done. And whatever was his intention it is clear that he set in train a considerable debate, involving Athenodorus, Cornutus, Boethus, Apollonius of Alexandria, Aristo, and unnamed commentators about problems involving the status of ‘wing’ and ‘rudder’ as Relatives, and what is reciprocal to them (187.18-189.12). Simplicius concludes by noting that ‘Archytas’ (I think somebody who adopts this name),[12] who is closely associated with Eudorus and who produced a derivative Doric work on categories himself, omits the reciprocal feature of the Relative altogether.

Archytas is also associated with Eudorus over the question of the order of the categories, both making Quality second, Quantity third, with Relative coming later. As a Platonist Eudorus feels that Quality must be more closely linked with Substance than Quantity can be. Since he recognizes that Aristotle is concerned with sensible Substance (206.14), it may be that Quality’s link with form and shape in the Timaeus has suggested this to him (cf. Simpl. in Categ. 206.15-18); again, the pre-cosmic condition in the Timaeus had already involved something Quality-like, but nothing very Quantity-like. Furthermore Eudorus goes beyond Archytas in putting Time and Place before the Relative. This again could be connected with the belief that until the one world is given Quantity, which in turn provides the conditions for separation by Time and Place (both conceived mathematically), one cannot have x standing in relation to y. One certainly cannot have the wing serving as part of the winged or the rudder serving as part of the ruddered.

An earlier discussion at 156.17 had credited ‘those who take Lucius’ position’ with criticizing the order Substance–Quantity–Relative­–Quality in favour of Archytas’ Substance–[Quality+Quantity]-Relative, itself compatible with the order of Categories 4. It is worth noting here that not even Andronicus would defend Aristotle on the position of Relative, but actually placed it last (157.18-20). So, in delaying Relative further, Eudorus had the backing of Andronicus. A non-Platonist could perhaps be content to deny that Aristotle was propounding any special order, as seen 155.31-32***, but for a Platonist such hierarchies are important; hence Simplicius will defend the order as both natural and suited to teaching (158.1-27), while Porphyry defended the Aristotelian order even more vigorously, referring explicitly to Empedocles[13] and to the ratios of the Psychogony in the Timaeus but earning himself a mild rebuke from the later commentator.

Eudorus has a number of detailed criticisms on the discussion of quality itself, beginning with the third line (8b27-9a13), critics generally (236.12-13) had objected that states (hexeis) and conditions (diatheseis) are listed under Quality as they had been under Relative. While some thought Aristotle’s distinction between states and conditions here to run counter to general usage, Eudorus objects that it runs counter to Aristotle’s own further statements. The distinction makes a hexis relatively stable in contrast to the diathesis, but Eudorus somewhere finds Aristotle committed to the instability of both—state too being easily got rid of.[14] This connects up with the next criticism, where the distinction is actually presumed. Eudorus now complains that Aristotle’s discussion of natural capacities under the heading of Quality (9a14-27) is superfluous, as any natural capacity must be either long-lived or short-lived, either a hexis or a diathesis (246.22-24).

It does not take long to realise that Eudorus is somebody with a liking for neat and orderly divisions, with a precise rationale. That actually fits well with what those who called themselves ‘Academics’ were doing in the first century BC.[15] At 256.16-18 he objects to the inclusion of heat, cold, health, and disease under both ‘conditions’ (diatheseis) and ‘affective qualities’ (pathêtikai poiotêtes), and he is actually taking issue with Andronicus’ attempt to discover a fifth type of quality at 263.27-29. At 268.13-14 he is puzzling over Aristotle’s exclusion of rare, dense, rough and smooth from the category of quality on the ground that they (but not straightness and roundness) are indicative rather of position (10a16-24).

On the whole Eudorus’ reaction to Categories 7 and 8 is one that questions the refinement of the organization of materials in Aristotle’s texts, often raising points that it would not be difficult to puzzle over today. Even though we might now be well able to supply solutions, and Porphyry nearly always had an answer for Aristotle too, it remains a fact that Aristotle has not always explained what he is doing and the basic principles behind his division. The Categories are simply not as clear as one might have supposed. Eudorus is not so much attacking Aristotle, as exposing weaknesses and countering what was probably a growing admiration for the Stagirite. At this time not even the Peripatetics were handling the text with great confidence.

Plutarch is one figure obviously influenced by Eudorus. He displays the same ability to indulge in criticism of other Schools in the Aristotelian tradition, and is certainly capable of applying that to Aristotle too, albeit constructively rather than destructively.[16] Aristotle is less of an enemy than the Stoics and Epicureans. Plutarch will also make positive use of Aristotle at times, and assume that he is bringing out material already explicit in Plato. Both Dillon and Karamanolis discuss a passage in the De Animae Procreatione (1023e) in which it appears that Plutarch is finding the categories already implied by Timaeus 37b-c,[17] and a Plutarchian work on the ten categories is to be found in the Lamprias catalogue. That both works talk of ten categories indicates an acceptance of the basic conceptual scheme that Eudorus did not share; in this respect Plutarch agrees with Alcinous 6 (158.43-4).

At around A.D. 160, and perhaps close in date to Alcinous, it seems that Nicostratus was composing an attack on the Categories in the tradition of a Platonist Lucius, aimed at all parts of the work. His objections are described as enstaseis (Simpl. in Categ. 1.21; 2.13; cf. 26.21; 30.16; 73.29; 76.13) or aporiai (Simpl. in Categ. 1.18; 2.1), and verbs of accusation such as enkaleô (Simpl. in Categ. 29.24; 58.15; 63.4; 127.30; 368.12; 370.1; 428.3) or aitiaomai (Simpl. in Categ. 231.20; 388.4; 406.6; 410.25) are regularly used, along with other vocabulary of polemics, such as antilegein and cognates (62.30; 390.15). At one point an accusation of ‘empty-talk’ (mataiologia, 58.15) is employed. The better known anti-Aristotelian Platonist Atticus (fl. c. A.D. 175) followed with at least one blow against the Categories himself (Simpl. in Categ. 30.17).

The significance of Nicostratus is probably not in the quality of his criticisms of the Categories, but rather his having prepared the way for Plotinus’ own worries about the Aristotelian work in a sequence of treatises, Enneads VI, 1-3. Plotinus is not here a polemicist, but somebody with a profound respect for Aristotle, who promoted in his educational circle the reading of Aristotle and his commentators as well as Plato and his commentators. Plotinus can see real purpose in Aristotle’s work insofar as one is dealing with the sensible and changing world, but that exercise was inferior to Plato’s attempt to engage with the categories of the intelligible and unchanging world. He seems caught between his own mentor Ammonius Saccas, of whom we are told that he held Aristotle and Plato to be in agreement on the most important doctrines,[18] and the problems posed by Nicostratus and by Lucius even earlier. The way forward to the Neoplatonic orthodoxy required that Aristotle should be presumed from the beginning to be a great philosopher but that problems about him, particularly where he seemed to deviate from Plato, should indeed be felt. Hence Simplicius (in Categ. 1.23-2.5) says that (i) Nicostratus should at least be thanked for providing the materials for businesslike problem-raising and the incentive for serious solutions, while (ii) Plotinus tackled the most businesslike lines of examination (pragmateiôdestatas exetaseis) prompted by the Categories. The implication is that in his three treatises Plotinus he did not stoop so low as to either raise or refute the more sophistic objections.

Plotinus’ philosophical acumen brought the services of clear and well meaning reasoning to the rehabilitation of our text. However, Plotinus did not show the same skills in modern exegetical techniques. These had been given a considerable boost in the middle of the second century by Numenius, who had been skilled in both allegorical interpretation and the drawing of fine distinctions that solved hermeneutic problems. Numenius had a rather synthetic mind, which enabled him to look at passages within their overall contexts and whole works within the context of a corpus. For Plotinus on the other hand little passages could be looked at in isolation or with a limited number of favoured passages for comparison. Like Ammonius,[19] he was driven by philosophy as he conceived it rather than by any commitment to a single philosopher and to accompanying hermeneutic techniques. Such techniques were displayed rather by those who favoured commentary as a means of philosophic teaching, and it is clear that Porphyry had considerable hermeneutic skills to add to his reasoning abilities and to his commitment to the philosophic value of both Plato and Aristotle. He is always thinking of what sort of work he is dealing with, and what could be expected given the purpose of the work. He is keen to tackle the earlier objections to what is being said as well as the deeper puzzles of earlier thinkers, and indeed much that we know of earlier Platonists would be lost but for Porphyry’s diligence, not only as a scholar but also as a corrector of the commentary tradition. He has a prodigious knowledge of the works of Plato and Aristotle, and this offers him a considerable resource for the solution to difficulties. Above all, it allows him to feel his way into a work on the author’s own terms, and to become, in a strange kind of way, a model to all of us.

So I conclude my journey with Simplicius’ own tribute to Porphyry:

 

After these, Porphyry, the cause to whom we owe everything fine, achieved with considerable labour a perfect exegesis of the book and solutions to all the objections in seven volumes that are addressed to Gedaleius.
