Reason and Persons in Classical Greece

In a post I wrote three years ago, before I abandoned this blog for the first time (in accordance with its name) I mentioned a passage in Plato’s Statesman (266e, if you must know) where the Eleatic Stranger, the main character in the dialogue, concludes a long discussion of what appears to be the “definition” of human beings with the claim that human beings are “featherless bipeds,” a definition that, if we are to judge by its presentation in Diogenes Laertius VI.40, achieved a certain kind of comic notoriety (see below). Only a few lines earlier the Stranger had suggested that an equally good definition of human being was the “two-legged pig” (266a5-b9; more precisely the two footed animal that is kin to the pig), and in the discussion leading to these odd conclusions the Stranger had explicitly argued that it is not a good idea to treat the human possession of rationality as the defining characteristic of human beings. To claim that human beings are distinct from other beings because of their possession of reason is to ignore the possibility that other animals might also be rational (cf. 263d, on the possibility of “rational cranes” [!]) and indeed to forget that divine beings are also rational (the rational cranes would be inappropriately “making themselves sacred” if they claimed to be special in virtue of their rationality). In sum, there is something much like “pride” in attempting to distinguish human beings from all other animals by the criterion of rationality, as the Stranger suggests in criticizing young Socrates (the main respondent in the dialogue; he is not related to the elder Socrates, who is the main character in most of Plato’s other dialogues) for his excessive haste in trying to separate human beings from all the other animals on that basis (262a; cf. also 263d).

I simplify a bit. The joke about humans and pigs rests on a comparison between the square root of four (likened to the nature of the pig) and the square root of two (likened to the nature of man – see Campbell, ad loc.) which has the effect of suggesting that in reality the natures of human beings and pigs are “incommensurable” even though the Stranger has just made them commensurable by a quirky mathematical “squaring” procedure (and even though, oddly, human nature is the one that turns out to be “irrational”). The claim that human beings are “featherless” uses a rare and poetic word (πτεροφυής, literally “feather-growing”) that points to a passage in the Phaedrus (251c) suggesting that human beings can “grow wings” and hence rise to gaze upon the forms of order – the good and the just, but especially the noble or the beautiful – even if they no longer have such wings. When my book on the Statesman comes out, you will be able to read my interpretation of these passages at excruciating length. Or you can consult my dissertation, if you are the hardy type and prefer the even longer version.

But regardless of these complications, throughout the dialogue human rationality is clearly presented as something deeply problematic, and certainly not as something that unambiguously marks the boundary between humanity and animality. Though the dialogue appears to be explicitly concerned with the question of what is a human being from 261b to 266e, the Eleatic never gives a simple and satisfactory answer to this question, much less asserts that that human beings are “rational animals;” on the contrary, his answer(s) merely emphasizes the physical differences between animals and humans (their featherlessness, lack of horns, etc.) . In the extraordinary myth that the Stranger makes up shortly after that discussion (my favorite in all of Plato, a story about a time when life ran “backwards”) he speaks about talking animals and attributes rationality not only to human beings but to a number of other embodied, animated creatures, including the universe as a whole (269d), which is indeed described as a kind of rational “animal.” To the extent that human beings have reason, the myth implies, it is divided into a multitude of forms of knowledge or arts which serve to make up for physical deficits that most animals do not have, rather than integrated into a genuine wisdom that truly differentiates us from them. Moreover, these arts are likened to the things that came out of Pandora’s box (274d-e; cf. Hesiod Theogony 536ff, Works and Days 42ff), increasing our physical powers (and hence allowing us to defend ourselves from wild animals) but not necessarily our ability to rule ourselves in a wise and reasonable way (but on the contrary creating the possibility of warfare and other political conflicts). Art or knowledge, in other words, is not for the most part presented as what distinguishes us from other animals but as the adaptive mechanism that enables us to survive as animals (just as horns or hooves are some of the adaptive mechanisms that allow animals to survive as animals).

Thus, whatever one may think of Plato’s ultimate views, it is not clear that he was overly concerned with saying that human beings are distinguished from animals on the basis of their rationality, or that he thought that the question of what distinguishes human beings from animals is easily answered by a formula. Moreover, it is not clear that Plato and later Ancient Platonists, in comparing human beings to pigs (or birds, for that matter) simply assumed that pigs were especially risible or low, as Stephen Clark points out in a lovely piece that is unfortunately inaccessible to anyone without access to a good research university library (“Herds of Free Bipeds”, 1995). On the contrary, there is some evidence that they considered that “curious, naked omnivore” (Clark’s words) worthy of respect. (And Plato perhaps followed the Pythagoreans in thinking this, but who knows?) . If the Eleatic points to the continuity between human beings and other animals, he does not necessarily imply that this is a sufficient reason to think that human beings are of little interest or importance, though he does suggest that we should not be too quick to assume our superiority.

To be sure, Aristotle and the Stoics are perhaps more concerned than Plato with distinguishing humans from other animals, and more definite about the essential difference between humans and animals; indeed, for the Stoics, the definition of human being as the “rational animal” would become a sort of commonplace (see, for example, Chrysippus, On Emotions, of which the relevant extant fragment is found in Galen [=SVF 3.462]). But contrary to popular belief, Aristotle himself, working in the shadow of Plato, never did clearly define human being as the rational animal: the passage normally and erroneously quoted to this effect (Metaphysics Z.12, 1037b13-14) actually has him saying that human being is the “two-footed animal” (τὸ ζῷον δίπουν), as if quoting Plato’s Statesman. This is not to say that Aristotle did not believe human beings were rational (he clearly thought that an important feature of human beings was their capacity for rational deliberation), or that they were not “higher” in some sense than other animals (he does say elsewhere that plants and animals exist “for the sake of” human beings, generating a natural hierarchy of beings which is not quite as easy to find in Plato). Yet it does suggest that Aristotle did not think that the question of the definition of human beings vis à vis other animals was the most important question we could ask about the nature of human beings. Indeed, to the extent that Aristotle is preoccupied with the question of human nature, he tends to emphasize that human beings are preeminently political animals (Politics 1253a1-4), a characteristic which they share with cranes, wasps, ants, and bees (History of Animals I.i.11), even if they are more political than these other animals. The important differences between human beings and animals do have something to do with the human capacity for reasoned speech (which only humans truly have, according to Aristotle), but these differences are ultimately best understood as differences of degree rather than of kind, for other animals have a capacity for communicative speech (though not reasoned argument or logos) and social or political life as well as human beings.

The reason for bringing all of this up is that I’ve been recently invited to respond to a paper by a colleague on conceptions of human beings and freedom in both the East (primarily India) and the West (including several conceptions traceable to ancient political thinkers like Plato and Aristotle). The paper claims that most of the “Western” conceptions of human being fail to define human beings properly, since they use criteria that are shared by other animals (like some forms of rationality and language, which are shared with the great apes), something which may in fact be true of some of these conceptions. But it seems to me that at least Plato and Aristotle were not overly concerned with precisely distinguishing human beings from other animals. In particular, I would argue that for Plato the idea that human beings are rational is a kind of hypothesis or aspiration, not a well established fact; the interesting question, for him, is what follows from our being rational (if in fact we are), or from our lack of rationality for our ability to rule ourselves wisely, not the question of whether we are the sole rational animals. Much less hinged on determining whether or not reason is the distinguishing mark of the species than in determining what the possession of reason implies for our ethical, moral, and political lives; and the nature of reason was itself put in question. (And also: the classical thinkers were much weirder than we give them credit for. The fact that they have been absorbed for so long into the history of Western thought should not prevent us from seeing them as just as foreign than the Indian thinkers that my colleague studies; they came, after all, from a world that was very different from ours in every important economic and social respect, and that world was full of gods and demons).

The transformation of this line of thought into a mere formula – that man is the rational animal – closed off some of the avenues for thinking about the nature of human and animal rationality that were still open to Plato and Aristotle. Much later on, however, Kant would turn the idea of man as the rational animal upside down to emphasize that what mattered for moral and political thought was not human being but rational being: the categorical imperative and other moral laws apply to rational beings, not just human beings, and Kant does not assume that there is only one kind of rational being. And similarly, in contemporary times, many ethical thinkers (such as Peter Singer) suggest that whatever characteristic is important for ethical or moral life, it is important across all beings sharing it, whether or not they are human; what matters is not the question of who is a human being, but who is the subject of ethical concern (a feature of Singer’s thought that accounts for its apparent callousness: some human beings lack the requisite characteristic, whereas some animals have it).

These thinkers take, in their different ways, the Eleatic’s critique of Young Socrates seriously: being excessively concerned with distinguishing human beings from animals (as some of the 20^th century existentialists were, by the way) bespeaks a kind of unjustified “pride.” Though humans and other animals are clearly different, it is all too easy to take excessive pride in whatever difference is found (tool use, language, reason, “freedom,” etc.) and hence set ourselves up as “sacred” without justification (as the cranes in the Eleatic’s view). It is too similar to the same processes that lead us to identify with this or that nation (as the Eleatic indicates by using examples of “nationalist” classification in his criticism of young Socrates: 262d-263a), those arbitrary lines that distinguish among human beings on the basis of their ability to “interbreed” (the joke is too complicated to explain here). And perhaps we can go further today, in the shadow of Darwin: most truly significant distinctions between humans and others are ultimately matters of degree. If human beings and other animals are all ultimately related in a web of descent with very fuzzy borders, it may not make sense to try to fix these frontiers and erect imposing border control regimes. That only encourages unclear thinking.

To be sure, there will be differences between “us” and other living beings; but it may make little sense to determine the meaning and moral consequences of these differences a priori. I do not know how we are to relate to elephants, or whales and dolphins, or the great apes, all beings that are political animals in the strict Aristotelian sense of the term, displaying language enough, and family structures, and politics and war enough (I’ve just been reading about hierarchy in the forest); or how we may need to relate to AIs one day perhaps, or indeed to ourselves, in all our multifarious variety of our social forms. But I do suspect that to attempt to find something that strictly distinguishes us from these other beings as if that characteristic were of ultimate importance, is to fall into young Socrates’ error. What distinguishes us from other similar beings may not be the most important thing about us; it may just be our featherlesness.

Footnotes on things I’ve been reading: Epstein and Axtell, “Growing Artificial Societies”

Epstein and Axtell, Growing Artificial Societies
(1996).

I've become very interested in the "artificial societies" approach to social science. The idea is that we attempt to understand the workings of a society not through "discursive" models (as in qualitative social science) or through game theoretical models with extremely simplified assumptions and homogeneous agents (as in more "quantitative" approaches), but by creating a simplified version of the society in silico. So we use software (or pen and paper; Schelling's pioneering models of segregation were studied without the benefit of a computer) to generate an environment and simplified agents that interact with one another, and then we see what happens. The advantages of this approach is that one can add complexity to a model in a controlled manner and study the resulting dynamics (rather than merely static equilibria); so, for example, one might start with agents who move and eat, then see what happens if you add the ability to trade, and so on (besides, it's fun to play around with such models). The disadvantages, however, come from the very flexibility of the approach, which allows for highly complex models: it is sometimes hard to tell whether or not a particularly interesting result is simply an artifact of the simulation or the consequence of some particular simplifying assumption (though it should be noted that the same is often true of traditional models, where striking results, like the pareto-optimality of free markets, are sometimes basically artifacts of the simplifying assumptions made for the sake of creating "tractable" models).

Epstein and Axtell report in this book the results of a pioneering 1994 simulation: "Sugarland". They start with a very simple environment, the "sugarscape", consisting of a two-dimensional surface (technically, a torus) with an unevenly distributed resource ("sugar") and add some very simple agents who can move around the sugarscape according to simple rules and "eat" the sugar. As they add more complex rules, they basically "generate" a number of features of societies – like migration patterns, cultural transmissions, combat, trade, credit relationships, disease transmission, etc. – and study how some simple rule changes affect these patterns. The book does not describe in detail how to do this (they give some information that might help in replicating the simulation, but no code); instead, one can read it as a kind of advertisement for the generative approach to social science. Epstein and Axtell excitedly argue that many phenomena can be understood as "emergent" effects of the interaction of agents following simple rules, and hence that the best way of understanding them is by looking at which simple rules are able to generate them. In general, I am very sympathetic to this idea; it is unlikely that we will ever fully understand polities and economies through models composed of homogeneous, fully rational agents.

But though Epstein and Axtell's results are often suggestive, it is not always clear that they have properly looked at the ways in which minor changes in the parameters of the simulation might disrupt the patterns they find, or sufficiently thought about how to interpret the results of their simulations. As a result, the book is somewhat disappointing: if you are already convinced of the utility of the generative approach, you may not learn much here, and if you are not, then you may think that the authors have not really addressed the important objections to the generative approach. A good example is in the chapter of the book on combat and cultural transmission. Here the assumptions made about how to model cultural transmission and combat between agents seem rather arbitrary (rather than based, for example, on research about human or animal combat), and though they explore a number of alternative specifications, the results seem only lightly grounded theoretically, more an artifact of the simulation than an illuminating model of actual cultural transmission or combat. (By contrast, the chapter on trade and credit is probably the most solid in the book, since they ground the results in economic theory and systematically explore some of the space of alternative rule specifications and parameter values for their agents. Nevertheless, their results there do not go beyond what most sophisticated economists already knew, and do not add much knowledge about the properties of dynamic adjustment in markets – we get no bubbles or other interesting phenomena, for example, and we would need to introduce something like production functions to make the model better reflect actual economies).

Of course, the book is 16 years old right now, and new advances have been made in agent-based simulation. Besides, as I mentioned above, the book is perhaps best read as an advertisement for the virtues of the "artificial societies" approach rather than as a contribution to the study of actual societies; it opens your appetite rather than satisfies it (I wanted to do some programming as I was reading it, to try to see if I could replicate their results). But I think it is fair to say that the book does not quite succeed at showing that the artificial societies approach is actually worth taking seriously (unless you are already convinced of its merits).

I suspect that in order to make the "generative" approach work better, we need to be clearer about how the simple rules that agents follow in the simulated world relate to the kinds of rationality displayed by real political and economic agents than this book is. I also wonder how we could use this approach to model political and not merely economic phenomena. This is something I would like to do: how would you model the emergence of the state, or the choice of political regime? Do you need to incorporate more rationality into the agents, or a way of representing social conventions? Anyway, all in all, I enjoyed reading the book, and people may find it gives them new ideas, if nothing else.

Footnotes on things I've been reading: Steven Pfaff's "Exit-Voice Dynamics and the Collapse of East Germany"

Steven Pfaff, Exit-Voice Dynamics and the Collapse of East Germany (2006).

Despite the unpromising title, this is a superb analytical narrative of the 1989-90 collapse of East Germany. Pfaff draws on oral history, archival evidence (including opinion surveys conducted in the last years of the GDR), statistical analysis, and basic threshold models of collective action to produce a work that is not only insightful but also a good read. (One of my favourite bits: Honecker and other Politburo members apparently tended to discount fairly accurate reports of the situation in the country by the Stasi because they thought they sounded too much like what they could hear on West German television).

The East German revolution was a rare beast: a revolution without revolutionaries (or even, in the final instance, counterrevolutionaries), made by people after work, in a (mostly) peaceful manner (despite some violent confrontations in Dresden and elsewhere), against a regime which, on the face of it, seemed unassailable. The SED (the East German Socialist Unity Party) controlled a huge apparatus of repression (the Stasi, the “sword and Shield” of the Party), was uninterested in concessions, and was apparently quite willing to use overwhelming force against challengers (as they in fact did at first). Dissidents in East Germany were few and far between, most of them were loyal to the idea of Socialist state anyway, even if not to the policies of the party (truly anti-socialist dissidents tended to be expelled to West Germany), and their organizations were wholly infiltrated by the state. The forms of ideological control in the GDR, as in other Leninist regimes, encouraged dissimulation rather than genuine loyalty (“preference falsification”, in Timur Kuran’s useful terminology) and opportunistic compliance, with the result that the population seemed to be passive and retreated from public life to “niches” of tightly linked individuals, as Pfaff convincingly shows. Moreover, despite the stifling political repression, East German citizens were not badly off by the standards of socialist regimes: they had enviable job security (made possible, in part, by the constant possibility of exit, which created a situation of labor scarcity) and many social and welfare benefits, though many of these benefits had started to decay in the last years of communist rule.

In such conditions, there was widespread “pluralistic ignorance” – people who were dissatisfied with the regime were unable to tell how widely their grievances were shared (as their social networks did not include reliable linkages beyond their niches), and hence were mostly unable to use “voice” effectively to press for changes in the regime. So why and how was this regime overthrown so completely in the space of a few short months?

The key theoretical argument of the book concerns the relationship between “exit,” “voice,” and “loyalty” (in Hirschman’s terms). The GDR was different from many other repressive regimes (with the partial exceptions of Cuba and North Korea in the socialist world) in being placed in a situation where citizens could take advantage of an “exit” option (by moving to capitalist West Germany). Exit was, to be sure, made difficult (through the Berlin Wall, among other things), but it was far more available to dissatisfied GDR citizens than other options, and it was more available to them than to citizens of other socialist states, especially since the FRG recognized them as citizens and gave them considerable assistance once they reached Western territory. As others (including Hirshman himself) have argued, the key event that disrupted the GDR’s “repressive equilibrium” was the “exiting crisis” of August-September 1989 (when thousands of GDR citizens took the opportunity to escape to the FRG due to the dismantling of Hungary’s border fence). Where Pfaff’s analysis differs is in arguing that the existing crisis had two contradictory effects. On the one hand it acted as a signal that dissolved pluralistic ignorance and activated voice (both “dissident” voice by people who simply wanted reform, and “insurgent” voice by people who wanted a revolution or unification with Germany), but on the other hand large amounts of “exit” also eroded the social networks necessary to sustain protest.

Pfaff traces the consequences of this dynamic in painstaking detail (at times perhaps too painstaking), and shows how the demoralization of low-level party members and security forces, the ambiguity of instructions from hardliners at the top, and the ability of protestors to police themselves (at least in Leipzig) and remain peaceful all conspired to produce cascades of protest that made the regime crumble. As the protests increased, the dissidents were marginalized in their advocacy for reform of an independent GDR, whereas the majority (but by no means all) of the population in the streets increasingly wanted “exit” from the regime via reunification, and were able to push for this outcome by increasingly exiting (the numbers are staggering – huge numbers of people exited the country before and after the Wall fell). A regime that must imprison its population in order to survive surely has no right to exist.

Pfaff shows how this was a self-organizing revolution, without much in the way of leadership or heroes – though some people played more of a role in it than others, the overall impression one gets is of leaders being pushed aside by the force of anonymous numbers. Among leaders, Kohl comes off perhaps best; though widely criticized at the time, he did what successful revolutionaries do: he seized the moment and rode the wave of protests to an outcome that had seemed all but impossible mere months before, whereas the East German dissidents failed to act as a revolutionary counter-elite. Honecker and the aging leadership of the GDR mainly come out as deluded old men, trapped in dreams they perhaps no longer really believed in, though of course one should not forget that they were responsible for the (sometimes relatively comfortable) incarceration of a country.

Though the book is a good read, there is at times a certain amount of repetition (the book could certainly have been shorter), and the statistical analyses may seem like too much to those looking for a simple history of the fall of the GDR. But for those looking to understand the causes of the fall of the GDR, this book does a much better job than a simple historical narrative.

Power

It is not often noted (an exception is Hemmenway 1994, p. 265, note 12 [JSTOR]) that the Stranger’s top-most category in his divisions, the “original ancestor” in all his genealogies, is dunamis, power (Sophist 219a4-6). The reason for this neglect is probably that the Stranger does not bring the matter up in his summaries or discuss explicitly the powers that are not forms of knowledge.

Yet in the context of the dialogue, the idea of dunamis as the topmost category in every division makes good sense, since it is also used as an (apparently provisional) definition of being (247d8-e4), and never really retracted; see here Heidegger (1997/1924-25, section 68.b, pp. 328-330) and Dorter (1994, pp. 161-162). All the genealogies or divisions seem meant to begin from the original ancestor of everything, namely being.

A Joke in Diogenes Laertius

From Diogenes Laertius VI.40:

Plato defined man as a featherless biped [Statesman 266e], and was much applauded [for that]. [Diogenes heard this and so] he took a plucked chicken into the school and said, "here is Plato's man." So Plato's definition was changed with the addition "with broad nails."

Get it? I didn't think so. Let's try it one more time in Greek:

Πλάτωνος ὁρισαμένου, Ἄνθρωπός ἐστι ζῷον δίπουν ἄπτερον, καὶ εὐδοκιμοῦντος, τίλας ἀλεκτρυόνα εἰσήνεγκεν αὐτὸν εἰς τὴν σχολὴν καί φησιν, "οὗτός ἐστιν ὁ Πλάτωνος ἄνθρωπος." ὅθεν τῷ ὅρῳ προσετέθη τὸ πλατυώνυχον.

Still don't get it? Well, it's not really a very good joke, but it's a joke. And perhaps it's worth ruining it with an explanation.

The introduction is classic: Diogenes walks into a bar and hears that Plato defined a chicken as a featherless biped. The detail about the applause is evidently intended to amuse us (who could applaud such a ridiculous definition, ridiculous even within the dialogue, as the Stranger notes in the Statesman?), not to report a fact. The punch line of the joke is that τὸ πλατυώνυχον “the quality of having broad nails” sounds in Greek much like τὸ πλατώνικον, “the platonic thing;” the “improved” academic definition is thus “man is a ζῷον δίπουν ἄπτερον πλατυώνυχον/ πλατώνικον,” a “‘platonic’ featherless biped.”

Ok, I said it wasn't a great joke, but I think it's nice to know that people in antiquity took that part of the dialogue with a sense of humor.

Functions and purposes

Among some commentators (e.g. Zuckert 2000, pp. 71-72) it has sometimes been argued that the difference between the Socratic and the Eleatic practice of philosophy lies in Socrates' attention to purposes. Thus, the argument goes, while the Stranger is busy creating purely "analytic" definitions of statesmanship, Socrates asks about the good to which statesmanship aims; and while the Eleatic casts around for "value-neutral" criteria for distinguishing sophist and philosopher, Socrates cuts to the nub of the matter by looking to the different motivations animating the practice of philosophy (the love of truth) and sophistry (a love of money, or reputation). The point is usually construed as a criticism of the Eleatic, and may support a view of the Eleatic dialogues in which the Eleatic is silently subverted: the failure of Platonic Eleatism serves to make Socratic philosophy all the more necessary.

It is true that the Stranger’s genealogies are unlike Socrates’ definitions of the arts in that they do not emphasize the ends to which the arts aim; the Stranger, for instance, in his definition of angling does not say why anybody would practice angling, or even explicitly say what is the end of angling, and in his last definition of sophistry he does not discuss why anybody would practice sophistry (since the references to money which were such an important part of the first four definitions of the sophist drop out in the sixth and seventh).

Nevertheless, these genealogies do incorporate the immediate function of the art (its ergon), a function which is naturally called an “immediate” purpose. What an art does – its ergon - is its end qua art, i.e., its function, though it may not be the ultimate purpose of the person practicing the art. The angler’s function, in this sense, is to hunt fish; and the function of sophistry is to seem wise, and these are things that the Stranger’s genealogies can inform us of. To ask why should anybody hunt fish or want to seem wise is to ask the question of the good of fish and that of wisdom, and this is a question that the Stranger certainly does not openly discuss, unlike Socrates.

That question, however, is implicit in the Stranger's depiction of a web of arts that are all connected in the Statesman. The good of an art can only be understood in reference to the function it plays in society; hence we cannot understand the problem of sophistry well until we come to understand the place it takes (or rather usurps) in the web of arts that constitute the city. In this sense the Stranger's and Socrates' methods seem more complementary than contradictory; we need not see in the Stranger's apparent lack of interest in the question of whether the sophist's motivations are good an actual disinterest in the goodness or badness of sophistry. On the contrary: as we learn (291aff), sophistry is genuinely dangerous to the polis insofar as it attempts to substitute for statesmanship. We might say that Socrates adopts the perspective of the individual, while the Stranger adopts the perspective of the "social system."

One, two, or three?

One of the most interesting moments in the prologue to the Sophist occurs after Socrates asks the Eleatic Stranger whether sophist, statesman, and philosopher are one, two or three (217a). The Stranger answers, without hesitation, that they are three. But his answer sits uncomfortably with what we might call "standard Platonism:" the view that the philosopher is the statesman. Shouldn't the Stranger have said that they are two?

Moreover, the Stranger will go on to suggest that the sophist has a techne, an art (221d), and that it is this possession of an art that makes him "countable:" it seems that it is because sophist, philosopher, and statesman have three distinct technai or three forms of knowledge that they can be said to be three. But in the Gorgias Socrates had not even allowed that the sophist had an art (Gorgias 463a6-b6). Shouldn't the correct answer to Socrates' question then be "one," namely, there is only one art, that of the philosopher, which is identical to the statesman's art, and the sophist has no real techne?

The problematic nature of the Stranger's answer has been noted by scholars in various ways. Notomi (1999, p. 22), for example, claims that the Stranger is not fully committed to the view that sophist, philosopher, and statesman are three distinct beings: the Stranger’s “answer is that they [the Eleatic school] assume (ἡγοῦντο) these three kinds, and he adds that it is nonetheless no easy task to determine what each of them is (217b1-3). The view that these are three kinds is presented as an assumption (not as fact), and remains such throughout the Sophist and Statesman. It really matters whether these three figures constitute independent, real kinds (γένη).” But the Stranger gives us no reason in either the Sophist or the Statesman to think that he eventually revises his answer: the assumption, if it is an assumption, is vindicated in the dialogues.

Most scholars seem to fall into two camps: those who argue that somehow the three must be two, and those who argue that the three are indeed three, but argue that this does not represent a departure from the traditional Platonic doctrine of the philosopher king. Here's a list:

1. Skemp (1952/1987, p. 21) argues that philosopher and statesman are really one, but that the “specific activity” of statesmanship can be isolated from philosophical activity more generally. (It is not clear if this means Skemp thinks that the correct answer to Socrates’ question is two or three).
   
2. Klein (1977, p. 200): the three are really two.
   
3. Strauss (1989, p. 218): three. He thinks this answer is compatible with the Republic: “[t]he fact that the philosopher is not identical with the king was recognized in the central thesis of the Republic, according to which the coincidence of philosophy and kingship is the condition for the salvation of cities and indeed of the human race: identical things do not have to coincide.” Yet he also notes that the difference between statesman and philosopher is not made sufficiently clear in the Statesman.
   
4. Lane (1998, p. 7, note 19): three.
5. Griswold (1989, p. 263, note 13): three.
6. Rowe (1995, note to Statesman 257b3-4) two, though he seems to suggest that statesmanship involves “special skills” that the philosopher by himself does not necessarily have (and so philosophy and statesmanship would really be three).
   
7. Notomi (1999, p. 25, especially note 82): uncertain, but thinks the question is extremely important, and seems to lean towards the “two” answer
8. Samaras (2002, chapter 8, especially p. 146): unambiguously two, though thinks that there are different conceptions of the statesman in the Republic and in the Statesman.
9. Voegelin (1987/1956a, p. 150): unambiguously two
10. Benardete (1984, pp. II.73-74), as usual, has the most interesting analysis, without settling on a specific number, though in his earlier piece (Benardete 1963 pp. 212, 223), he was much more explicit in thinking that philosophy and statesmanship were different.
    

We might also note that the Athenians in general might think that the answer to Socrates’ question is “one” – philosopher, statesman and sophist are all forms of sophistry. Wolff (1991, p. 25) also notes that “one” is the sophistic thesis (not so much that of the Athenian people).

What are the implications of answering the question with "two" or "three"? It would seem that saying that philosopher and statesman are distinct forms of knowledge should indicate that the thesis of the Republic is not really tenable in the form in which it is usually understood (perhaps Plato changed his mind?); and moreover, it would necessitate a ranking of philosopher and statesman (perhaps the philosopher is inferior to the statesman?). More dramatically, perhaps, a separation of philosophy and statesmanship might create a space within Plato's political philosophy for a different sort of relationship between philosophy and politics than the one Plato is usually identified with (i.e., the -prudentially qualified- imposition of philosophical principles on political affairs).

But in order to see whether philosopher and statesman are the same or not, we need to understand what it would mean to say that they are distinct. My idea is that what we have here three distinct relationships to wisdom, each of them associated with a particular form of knowledge: the pretend wisdom of the sophist (associated with an art of pretension, of making images), the search for wisdom of the philosopher (associated with a dialectical science that facilitates this search), and the actual wisdom of the genuine statesman (associated with an art of measure and a real knowledge of forms). Each of these can be understood as "images" of wisdom, but only one of them (statesmanship) really is actual wisdom. So I think that Plato really means to suggest that there are three (not two) different figures here, each distinguished by a particular art and a particular relationship to the possibility of wisdom.

Images I

The question of images is central to the interpretation of the Sophist, as I indicated earlier. Indeed much of the dialogue is concerned with establishing that images and image-making are possible, against the sophistic argument that they are not possible, since the sophist is identified as a kind of imitator or image-maker, and in particular as an imitator of wisdom, i.e., somebody who in his performance gives the misleading impression of being wise (268c). Yet for all this the discussion of images in the dialogue remains marginal and misunderstood in the scholarly literature on the Sophist, in part because the passages on images and imagemaking in the dialogue have appeared rather puzzling to interpreters.

The Stranger discusses images explicitly beginning at 235b8ff. The relevant passages are worth quoting in full (235d-236c). In Fowler's translation, from Perseus:

Stranger
I see the likeness-making art as one part of imitation. This is met with, as a rule, whenever anyone produces the imitation by following the proportions of the original in length, breadth, and depth, and giving, besides, [235e] the appropriate colors to each part.

Theaetetus
Yes, but do not all imitators try to do this?

Stranger
Not those who produce some large work of sculpture or painting. For if they reproduced the true proportions of beautiful forms, the upper parts, you know, would seem smaller [236a] and the lower parts larger than they ought, because we see the former from a distance, the latter from near at hand.

Theaetetus
Certainly.

Stranger
So the artists abandon the truth and give their figures not the actual proportions but those which seem to be beautiful, do they not?

Theaetetus
Certainly.

Stranger
That, then, which is other, but like, we may fairly call a likeness, may we not? [236b] And the part of imitation which is concerned with such things, is to be called, as we called it before, likeness-making?

Theaetetus
It is to be so called.

Stranger
Now then, what shall we call that which appears, because it is seen from an unfavorable position, to be like the beautiful, but which would not even be likely to resemble that which it claims to be like, if a person were able to see such large works adequately? Shall we not call it, since it appears, but is not like, an appearance?

Theaetetus
Certainly.

Stranger
And this is very common in painting [236c] and in all imitation?

Theaetetus
Of course.

Stranger
And to the art which produces appearance, but not likeness, the most correct name we could give would be “fantastic art,” would it not?

Theaetetus
By all means.

Stranger
These, then, are the two forms of the image-making art that I meant, the likeness-making and the fantastic.

Here is part of the Greek:

Ξένος
μίαν μὲν τὴν εἰκαστικὴν ὁρῶν ἐν αὐτῇ τέχνην. ἔστι δ᾽ αὕτη μάλιστα ὁπόταν κατὰ τὰς τοῦ παραδείγματος συμμετρίας τις ἐν μήκει καὶ πλάτει καὶ βάθει, καὶ πρὸς [235ε] τούτοις ἔτι χρώματα ἀποδιδοὺς τὰ προσήκοντα ἑκάστοις, τὴν τοῦ μιμήματος γένεσιν ἀπεργάζηται.

...

Ξένος
οὔκουν ὅσοι γε τῶν μεγάλων πού τι πλάττουσιν ἔργων ἢ γράφουσιν. εἰ γὰρ ἀποδιδοῖεν τὴν τῶν καλῶν ἀληθινὴν συμμετρίαν, οἶσθ᾽ ὅτι σμικρότερα μὲν τοῦ δέοντος [236α] τὰ ἄνω, μείζω δὲ τὰ κάτω φαίνοιτ᾽ ἂν διὰ τὸ τὰ μὲν πόρρωθεν, τὰ δ᾽ ἐγγύθεν ὑφ᾽ ἡμῶν ὁρᾶσθαι.

The distinction the Stranger makes here between likeness-making ("eikastic" imitation) and the making of appearances ("fantastic" imitation) has been the source of endless confusion. Among earlier interpreters, Philip (1961, p. 459, JSTOR), for instance, makes the strange suggestion that “[e]ikastike would appear to be a class without members, serving only a purpose of symmetry.” His argument relies too much on the Cratylus, where the distinction does not appear, though Socrates does discuss images. Cornford (1935, p. 198) makes the equally misguided suggestion, under the influence of arguments in the Republic (where, again, the distinction does not occur) that “[b]oth here and in the Republic the whole of fine art, considered as ‘imitative’, falls under the art of making ‘semblances’, not ‘likenesses’. Plato does not mean that there is a good and honest kind of art which makes ‘likenesses’ reproducing in all three dimensions and the natural colors of the original” – something which in fact he must mean.

More contemporary interpreters do better, though there is still no consensus regarding the meaning of the distinction. Blondell (2002, pp. 365ff.), for example, argues that εἰκόνα are “analytic images,” but she mars her argument by suggesting that only eikastic imitation is pedagogically beneficial. Like her, most interpreters of the distinction (so Notomi 1999, Palumbo in the Proceedings of the III Symposium Platonicum) operate under the assumption that Plato must obviously value eikastic imitation more than fantastic, or clearly identify philosophy with eikastic rather than fantastic imitation (Nightingale 2002 is an exception: she argues that Plato could have used both forms of imitation for pedagogical purposes, though her views are dismissed by Rutherford in the same volume). But the assumption is unwarranted; the Stranger says little about whether we are to consider eikastic imitation the sole province of the philosopher, or to value it always more than fantastic imitation.

What, then, is the Stranger trying to say with this distinction? I draw here on Benardete 's somewhat opaque, but useful interpretation of this passage (1984, pp. II.105-112). I take it that the Stranger is suggesting that there are two ways in which images can represent objects, and that both of them are flawed, though in different ways. Let's take, for example, the image of a straight road:


This is a "fantastic" or distorted image of the original: in order to represent the road so that it looks like a road, the picture had to distort the actual proportions of the road, primarily by making the parallel lines of the road appear to converge. The image's summetria or proportions are thus different from the summetria of the original, or more precisely, the image and the original do not have a common measure (a summetria). This was necessary because the road is "too large," as the Stranger notes, to be eikastically represented and still look like the road looks.

But what would an eikastic image of the road "look like"? Here is one (not, of course, of the same road):


Though this particular image is not eikastic in every respect described by the Stranger, it is eikastic in the sense that the image preserves the proportions of the original: the sides of the road really are parallel to each other, and they are depicted as parallel in the image. But of course, because from our normal point of view the road does not look like that, a fantastic image is required - a perspectivally distorted image - if we want the image of the road to look the way in which a road would normally look to us.

Fantastic images are distorted - and thus flawed as representations of their originals - precisely in order to account for our flawed perspective. Eikastic images are not distorted from the point of view of the original (that is, they preserve the original proportions of the object) but they appear flawed because they are not well adapted to our point of view. The relationship between an eikastic image and its original is like the relationship between the central circles in the Titchener circles illusion:

Both red circles are in fact identical in size, but they look different to us given the limitations of our perceptual apparatus.

In the Greek context it seems likely to me that the Stranger is referring to a form of perspectival painting, where figures have to be systematically distorted in order to look right to us. The point of this distinction, however, is the subject of an upcoming post...

Theodorus' judgement and the art of measure

I mentioned earlier that we can see a tension between Socrates and Theodorus in the dialogues of the trilogy. Socrates and Theodorus, despite superficially friendly relations, seem to be fundamentally at odds, with Theodorus in expressing or implying doubts about Socrates' philosophical proficiency at several points (e.g. Theaetetus 169a6-b4). I also indicated that if we take this tension seriously we might read the dialogues in part as a critique of the limitations of certain mathematical modes of thinking. Here's a small example of what this could mean.

When Socrates expresses the fear that Theodorus might have brought a refuting god who has come to punish them to their gathering, rather than a mere "stranger," Theodorus ambiguously reassures him: this is not the way of the Stranger; he is more "measured" than those who take disputation too seriously. There is a more than a hint that Theodorus includes Socrates among the latter, i.e., somebody who takes disputation too seriously (Theaetetus 169a6-b4). As Seth Benardete (1984, p. II.70) puts it:

Theodorus, ... [w]ith his usual rudeness, tacitly agrees that Socrates is poor in speeches ... The Stranger is not another Socrates, whose “love of naked exercise in speeches” lets no one get away from him without first rendering an account of himself.

Now, when Theodorus says that the stranger is "more measured" than somebody like Socrates, he uses the word μετριώτερος, which evokes the notion of measure, τὸ μέτριον, discussed much later in the Statesman (beginning at 283c). There, the Stranger distinguishes between two arts of measure: one kind that measures things in relation merely to each other (as bigger or smaller than each other), and another kind that measures them in relation to a mean (as too much or too little in relation to it). The Stranger puts all the arts of measure that have to do with number, length, depth, and surface, i.e., the mathematical arts, among the arts of measure that do not measure "against the mean" and hence cannot find the proper measure (the neither too much nor too little) of things (284e4; for a fuller argument on this point, see my paper here). Mathematicians, in other words, are not qualified by virtue of their mathematical art to say whether someone is "too preoccupied" with disputation. But that is precisely what Theodorus is claiming by saying that the Stranger is "more measured" than somebody like Socrates; he is trying to measure against the mean.

Thus, to the extent that we can refer forwards to the discussion of measure in the Statesman when thinking about Theodorus' subtle put-down of Socrates, we can see that Socrates has the last laugh: Theodorus is not qualified, according to the implication of the Stranger's argument, to judge whether the Stranger is more or less measured than Socrates in the matter of disputation, except in the purely mathematical sense that the Stranger engages in less disputation than Socrates. Whether the Stranger engages in the right level of disputation is something that Theodorus cannot judge.

To be sure, all of this is somewhat speculative. Others see less of a tension between Socrates and Theodorus (e.g., Miller 1980, pp. 11-12), and most see no tension at all (most agree with Campbell 1867, note to 216a5, who long ago argued that Theodorus' reassurance merely shows that Socrates expressed an “ironical fear” of having the “Zenonian negative dialectic to bear on his own (i.e. Plato’s) mode of reasoning”). The point, however, is that if we take seriously both Theodorus' status as a mathematician and the apparent downgrading of a purely mathematical art of measure in the Statesman, then Theodorus' judgment about the Stranger and Socrates is put into question: he cannot tell us that the Stranger is a better philosopher than Socrates by engaging in a less disputatious form of philosophy.

The Charge Against Socrates

I mentioned earlier that the Sophist and the Statesman can be understood as a sort of philosophical trial of Socrates. But what is the charge against Socrates in this philosophic trial?

The only plausible charge is an accusation of sophistry. This charge is not so different from the actual charge leveled against him by Meletus, namely, that he introduced new gods into the city and corrupted the young; both Aristophanes in the Clouds and the Platonic Socrates in his defense in the Apology (18b) understand the accusation to be that he is somebody who makes the weaker argument appear stronger and thereby corrupts the young, an activity associated with the sophists. The Sophist, with its concern for the correct definition of the sophist, can then be understood as a methodical attempt to figure out whether there is anything to the charge.

To be sure, the Eleatic Stranger never makes this accusation. He and Theaetetus simply develop various definitions of the sophist, never explicitly connecting them with Socrates. The fifth definition of sophistry, however, beginning at 226a and ending at 231b8, is, as scholars have long recognized, alarmingly close to Socrates' own practice as described in the "Socratic" dialogues. The sophist that the Stranger and Theaetetus describe engage in the refutation of the ignorance that does not know it is ignorance, as a form of education, which certainly seems to be much like what Socrates does in many "early" Platonic dialogues. Here's the Stranger's final summary of their definition (231b, Fowler translation in Perseus):

... let it be agreed that part of the discriminating art is purification, and as part of purification let that which is concerned with the soul be separated off, and as part of this, instruction, and as part of instruction, education; and let us agree that the cross-questioning of empty conceit of wisdom, which has come to light in our present discussion, is nothing else than the true-born art of sophistry.

Is the Stranger indicting Socrates by this definition of sophistry? Though Theaetetus is ready to describe the master of the cathartic art as a sophist, the Stranger seems uncertain (230e-231b):

Stranger
Well then, who are those who practise this art?
[231a] I am afraid to say the sophists.

Theaetetus
Why so?

Stranger
Lest we grant them too high a meed of honor.

Theaetetus
But the description you have just given is very like someone of that sort.

Stranger
Yes, and a wolf is very like a dog, the wildest like the tamest of animals. But the cautious man must be especially on his guard in the matter of resemblances, for they are very slippery things. However, let us agree that they are the sophists; for I think the strife will not be about petty discriminations [231b] when people are sufficiently on their guard.

It is not clear here whether the sophist they have described (and hence Socratic practice) is the wolf or the dog in this analogy, and hence whether the Stranger is indicting or absolving Socrates.

Scholars disagree as well: some feel compelled to deny that the image of the “cathartic” sophist really applies to Socrates at all (Bluck 1975, pp. 40-46; Diès 1925, p. 272; Kerferd 1954), even if the similarities must be acknowledged as part of the philosophic “trial” of Socrates (Friedländer 1964, p. III.237); others argue that Plato himself is in doubt (Campbell 1867, p. li); yet others deny that the Stranger “disvalues” this sort of sophistry, though they acknowledge that it is a sort of sophistry that needs to be superseded, perhaps by by the positive method of the latter Plato (Cornford 1935; Dorter 1994, pp. 131-134; Heidegger 1997/1924-2, p. 263; Kerferd 1954), pp. 85-97); some see here a kind of (ambiguous) indictment of Socrates (Benardete 1984, p. II.99; Howland 1998, pp. 203-206; Notomi 1999, section 2.3, pp. 64-68); finally others see here an association between Socrates and sophistry, but think that this implies that sophistry is necessary and universal, and so see no real "indictment" of Socrates (Wolff 1991, esp. p. 51). The very variety of scholarly reactions to the question testifies to the ambiguity of the passage and the stakes of the issue: scholars feel compelled to take sides on the matter, to decide whether Socrates should be indicted as a sophist or not, and if not, why not.

If Socrates appears as a sophist, it should be noted that the Eleatic Stranger does not escape suspicion either (Lassègue 1991, in a weak sense; Scodel 1987; Tejera 1999, chapters 10 and 11). As Notomi (1999, p. 72) notes, it is only Theodorus “who introduced and regarded him as a philosopher;” and certain features of the definitions of the sophist (primarily the second, the itinerant merchant of learning, and the last, the human producer of distorted images of wisdom [such as the Statesman’s myth] in an intelligible medium, ironically, in private with short speeches that can produce contradiction) seem applicable to the Stranger even more than to Socrates. One could also add that at one point the Stranger does imitate a sophist fairly explicitly (239e1-240c3), a passage commented on by Campbell (1867, p. xxii): “The Eleatic Stranger is like the Sophist he describes, whose “sense is shut” to everything but the dry light of reason.”

This confusion of appearances is simply a restatement of the problem posed by Socrates at the very beginning of the dialogue (216c-d): the philosopher sometimes appears as a statesman, sometimes as a sophist, sometimes as a madman, and are therefore hard to make out clearly. Plato seems to leave it as an exercise for the reader to distinguish Socrates from the sophist or else to indict him and find a new philosophical path; we are invited to take sides. It is never absolutely clear whether Socrates is a sophist; at any rate, he is perilously similar to the sophist, like a dog to a wolf, and pinpointing the essential difference is not easy from a distance.

In order to see the difference between them we have to understand images - what they are and how they work; and so the dialogue moves on to a thorough consideration of images. More on images this week...

Socrates' awe and the Stranger's awe

I earlier posted about the Stranger's αἰδώς (shame or awe) on responding to Socrates' request that he use a vaguely "Socratic" approach to the conversation, with short exchanges rather than long speeches. It is worth noting also that the Stranger’s αἰδώς mirrors Socrates’ own remembered αἰδώς at encountering Parmenides as a young man (Theaetetus 183e6), an encounter that Socrates just recalled (217c5-7).

There, Socrates showed himself as an overconfident young with much to learn yet from a more experienced philosopher. As we learn from the Parmenides (127eff), Socrates thought he could easily refute Zeno's paradoxical arguments about the many and the one by introducing a version of the theory of forms. But the aged Parmenides himself refutes Socrates' arguments, leaving him at a loss. It is this that seems to be the source of Socrates' reverence or awe; not Parmenides' age by itself, but the fact that Parmenides showed him the difficulties with his own position.

Now, the Stranger must have heard of Socrates’ fearsome powers of refutation before meeting him; otherwise his αἰδώς could only be explained as the conventional shame of a younger man upon meeting an older man. This is a possibility, since Theodorus describes him as merely a companion of those around Parmenides and Zeno, not as a companion of Parmenides himself; the Stranger may never have met Parmenides, if we take Theodorus literally. But we are never told that the Stranger is a young man.

At any rate, Socrates appears to the Stranger as a figure inspiring reverence and shame, not someone to be trifled with lightly, especially not by giving oneself airs and putting on exhibitions; we might say that Socrates is to the Stranger as Parmenides was to Socrates. But just as Socrates did not simply bow down before Parmenides’ wisdom (even if he was rendered uncharacteristically at a loss), we should not expect the Stranger do so before Socrates. His very presence is a challenge to Socrates. And yet he seems ashamed of his possible challenge: if he is there to pass judgment on Socrates’ philosophical practice, the presence of a silent Socrates observing him also constitutes a test of the Stranger’s own philosophical activity, including his political thought.
