All readers of Plato encounter the tortured and provisional character of philosophical conversation in the dialogues (Ap. 37A3–41C7; Gorg. 527D2–5; Phd. 107A2–B10). The Gorgias, Protagoras, and Euthydemus discuss several aspects of philosophical exchanges, especially the distinction of the elenchus from rhetoric, eristic, and other sophistic techniques. The very possibility of successful conversation is a persistent theme.Footnote 1 One problem for scholarship is the significance of discourse methods that Plato's Socrates adopts beyond purely intellectual methods of persuasion. In several passages, the assumption voiced by Socrates is that linguistic understanding depends on a match of inner experiences. Otherwise, the speakers cannot easily reconcile their dissimilar experiences. As I will argue, there is an underlying engagement with the historical Gorgias on discourse and psychology, as well as Parmenides on philosophical logos. I hope that these contrasts will help to place some familiar passages and themes in a new light.
I
I will begin with a short preface to my topic. There is heavy attention to conversational matters in virtually all the dialogues, although this is often related to personal conflict. Personal conflict is especially prominent in the Gorgias and Euthydemus, an account of Socrates' testy encounters with the sophists and rhetors (Gorg. 486E5–6; 487E6–7; Eud. 277D1–278D3; 304C6–D2). Another feature in many dialogues is the angry emotional response of Socrates' interlocutors (and listeners) when subjected to dialectic, whether self-directed or other-directed (Symp. 215D1–216B6; Soph. 230B4–E3). However, I propose that we take seriously what goes wrong in the conversation itself.
Let me list some examples of what I mean. One problem is frustrated understanding, a theme I will develop in this paper. For example, at a late stage in his exchanges with Callicles in the Gorgias, Socrates remarks, ‘Now you and I are doing an odd thing in the conversation (en tois logois), for in the entire time during which we engage in dialogue (dialegometha) we cease not at all, always coming back again and again to the same point and remaining in ignorance of each other, what we are saying’ (Gorg. 517C4–7; cf. 488B8–491D3). Another problem is mis-matched levels of discourse. This is a recurrent theme in the first half of the Euthydemus, based on the contrast of Socratic seriousness and eristic frivolity (Eud. 278B2–D3; 288B3–D4). And still another problem is one's style in dialectical exchanges. For example, Socrates and Euthydemus dispute Socrates' penchant for asking questions in dialectical situations that would require an answer (Eud. 295B2–9); also, consider the uncomfortable adjustment of interlocutors to Socrates and vice versa (Prot. 335A9–C7; 336B7–D5). Finally, there is concern with the emotions that disturb the conversation, especially anger or annoyance (Prot. 332A2–4; Eud. 285A2–D6).
Somehow or other, these conversational dramas are meant to showcase the Socratic way of promoting virtue. The elenchus is supposed to lead speakers to moral goodness and purge people from evils.Footnote 2 Unfortunately, it has a quite mixed record of success in the dialogues, particularly the more ambitious dialogues that tangle with the sophists.Footnote 3 In the Euthydemus, no developed elenchus ever confronts Euthydemus and Dionysodorus (Eud. 286B7–288A7 might count as an exception), while Socrates' protreptic cross-examination of Cleinias succeeds without much struggle. The polemical Gorgias also presents arguments with protreptic overtones, but to a lesser degree than the Euthydemus. Finally, the Socrates of the Protagoras does not engage in much protreptic, while the elenchic passages eventually embarrass Socrates for denying that virtue is teachable.
In these dialogues, especially the Gorgias and Euthydemus, Socrates and his interlocutors persist in misunderstanding, on account of their root experiences, desires, and values. The psychological barriers eventually become quite evident.Footnote 4
II
This issue takes shape in the dialogues that feature extended engagements with the sophists, short of the sweeping ambitions of the Republic. At least three passages directly claim that likenesses of experience and desire make linguistic understanding possible on virtue and the good life (Gorg. 481C5–D5; 482C4–486D1; Prot. 348C5–348E1). This is the weaker claim. Sometimes we find the stronger claim (with Collingwood) that understanding may be enabled by prior experiences and desires, but it may also be disabled by our experiences.Footnote 5 In the spirit of the weaker claim, Socrates tries to win over Protagoras to a serious question-and-answer exchange (Prot. 348C5–E1; cf. Prot. 347E1–349A6).
Protagoras, I said, don't think that my discourse with you proceeds under any other counsel than to examine matters that I myself find puzzling on various occasions. I think that Homer said it all, ‘Advancing in tandem, one perceives before the other’ (Il. 10.224). Human beings are simply more resourceful this way in action, speech, and thought. If someone has an inner experience, he immediately starts going around seeking to whom he might show it and to whom he might confirm it, until he is successful. And so for this reason I would gladly discourse with you more than anyone else, considering that you would investigate most impressively concerning matters that are suitable for decent men to examine, and particularly concerning virtue.
The idea is that inner experiences (eiper te noêsêi) are communicable insofar as the soul finds a match for them (cf. Rep. 499A11–C2; Tht. 155D1–5). The claim is plausible enough. For example, imagine that nothing was generally known about eclipses. It would be more likely for two people (take Socrates and Callias) to reach understanding about an eclipse of the sun witnessed only by Socrates (Phd. 99D4–E4), if Callias had previously seen an eclipse of the moon. And in the case of philosophical investigations, it makes sense to devote one's efforts to a virtuous or morally promising interlocutor. It has been argued that Socrates and Protagoras share some important similarities of experience and philosophical outlook, in spite of their differences over the nature and teachability of virtue.Footnote 6 In many respects, Protagoras comes off better than the other sophists of the dialogues; in fact, he is the only interlocutor who swaps views with Socrates in the course of the arguments.
Alcibiades' drunken speech from the Symposium provides an interesting comparison on confirming experiences. By coincidence, he features in both the Gorgias (dramatic role) and the Protagoras (mention by Socrates). Philosophical inclination is described in terms of snakebite (Symp. 217E6–218B7; cf. Phd. 62A–69E).
Further, the experience of someone suffering from snakebite holds in this connection. For word has it that someone suffering this experience is not willing to speak about it except with those who have been bitten, insofar as they alone will understand and will pardon if one is driven to do or to say quite anything on account of the agony. But as things are, I have been bitten by something far more vexing, in fact the most grievous of bites one might incur – I mean the heart, or soul, or whatever one should call it, smitten and bitten by the discourses of philosophy, which fasten their grip more fiercely than a viper, whenever they pierce the soul of a promising youth and compel him to do and say anything whatever. Now I see Phaedrus, Agathon, Eryximachus, Pausanias, Aristodemus, Aristophanes – and as for Socrates himself what need one say, and so many others? All of you have tasted the Bacchic madness of philosophy, hence all of you will listen. You will pardon the things having been done then and the things being said now. But the slaves, and any other base philistine, shut the mighty gates of your ears.
Of course, this is a far cry from the lofty picture advanced by Diotima, that an enlightened desire for one's own good nourishes a desire to give birth in the beautiful, and that we might express our higher desires by way of preserving our inner value for posterity (Symp. 207C8–212C3). For Alcibiades merely claims that it is pointless to discuss the experience (pathos) of philosophical passion with the uninitiated. Actually, Alcibiades flatters to deceive, for his entire speech betrays several points of misunderstanding; in any case he can never capitalize on his spectacular prospects for virtue.Footnote 7 His chaotic life cuts his potential short (Tht. 150E4–5). Nevertheless, he expresses the stronger claim, if from a rather irrational angle.
Still more passages on this topic appear in the Gorgias, another dialogue which examines philosophical conversation.Footnote 8 The role of prior experiences is developed by Socrates when he first engages Callicles (Gorg. 481C5–D5).
Well, Callicles, if human beings didn't share common experiences, some sharing one, others sharing another, but one of us had some unique experience not shared by others, it wouldn't be easy for him to communicate what he experienced to the other. I say this because I realize that you and I at present share a common experience: each of the two of us is a lover of two objects, I of Alcibiades, Clinias' son, and of philosophy, and you of the dêmos of Athens, and the Demos who is the son of Pyrilampes.Footnote 9
Again, we find the claim that communication is facilitated by matched experiences, but also impeded by mis-matched experiences (the stronger version). As it turns out, Callicles is far more intransigent than, say, Protagoras. Although Socrates praises Callicles at one point for his sincerity and outspoken manner (Gorg. 486E5–488B1), he offers less philosophical insight than Protagoras on the subject of virtue, in spite of the common ground supposed by Socrates (Gorg. 481C5–D5).
At the outset of the Callicles sequences, Socrates hopes that Callicles can be reconciled on the basis of their similar experiences of dual love. Different uses of the term I translate as ‘experience’ (pathos, pathêma) appear in the dialogues.Footnote 10 In this passage, a psychological experience of desire is meant (erôs, Gorg. 481D3, cf. 513C4–D1).Footnote 11 The content of Socrates' shared experience includes the concept of duality – a strong desire which has dual objects.Footnote 12 Reaching people also means incorporating their fundamental desire for the good. As obscured as it might be in Callicles' love for dêmos/Demos (Gorg. 513C4–6; cf. 1 Alc. 131E10–132A7), his desires can be explained in terms of his profound desire for what is truly and unqualifiedly good. So in this derivative sense, the highest good (virtue) is what might connect them in the pursuit of excellence (Gorg. 527D1–5). Presumably, Socrates' mention of Alcibiades evokes the Symposium – Socrates' power to draw Alcibiades in the pursuit of philosophy. The erotic ascent of the Symposium provides a helpful analogy, beginning with bodily attraction (Symp. 204D1–210B6; cf. 1 Alc. 131C5–132A7). Beyond the lower stages, Callicles might be drawn upwards towards the more worthy goods sought by the philosopher. In view of this one great desire for the good, all our lesser desires for bodily symmetry or civic glory can be explained (Symp. 205A5–206B10). If Callicles could see clearly what he is really reaching for, he would embrace the goods of justice, temperance, self-sacrifice for the good of the community, and so on. He would discard his egoist moral stance.
In the course of dialectical conversation, the experiences of Socrates and Callicles are clarified to show certain differences. This process depends on a kind of ‘psychological realism’ – the soul contains experiences that are discoverable, communicable, and rooted in perdurable human nature. Callicles does not deny Socrates' observation that he is obsessed by love for the dêmos, but his love involves the desire for power over the Athenians.Footnote 13 This provides a shameless account of what it is that Callicles really wants (Calliclean frankness), or what anyone else of sufficient quality would want (Gorg. 482C4–E6; 527E5–7). Socrates would be wiser to forsake philosophy and pursue the more honorable aims of political power. Callicles' version of the good life is one of unrestrained hedonism, consisting in endless satisfaction of appetites (Gorg. 491E5–492C8) and acquiring power over others in the city. Socrates, on the other hand, allows that the good life requires the satisfaction of desires for things like external goods, but in a moderate and more self-sufficient way (Gorg. 491D10–E1; 493C5–7; cf. Rep. 558D4–559D2). Philosophical conversation reveals that Callicles is not adequately primed for philosophy; some would call this a ‘failure’ of Socratic methods.Footnote 14 For Callicles' soul has certain stable features, and there are clear limits to Socrates' rational persuasion. Perhaps there is some contrast drawn by Plato between the deepening alienation of Callicles in the latter half of the dialogue and the conversational multi-lateralism of Gorgias in the later stages (Gorg. 497B4–10; 506A8–B3); Gorgias shows greater proclivity to take seriously the values and methods of philosophy.
Now why is this scheme important? As I have already suggested, one point is that experiences and desires actually can be genuinely mismatched. It is possible to be wrong about who is a soul-mate and who is not, the very thing that is inconceivable for the historical Gorgias (as we will see). For the dialogue eventually reveals that Socrates and Callicles do not have sufficiently similar experiences (cf. Socrates and Alcibiades in the Symposium). (It is an interesting question whether further conversation is pointless for speakers with insufficiently similar experiences. This question would require a renewed investigation into the values and purposes of philosophical conversation.Footnote 15) Or take the case of respondents, talented at dialectical exchanges, but who resent being wrong about the strength of arguments. This process is beneficial to the respondents, yet they might never progress in philosophy, for winning such contests is too deeply ingrained in their souls (Phd. 89D–E).Footnote 16 In fact, this may be a permanent and genuine feature of such initially promising souls, a feature which comes to light under the pressures of dialectical argument (cf. Euthydemus and Dionysodorus in the Euthydemus). So I think that this kind of soul clarification is often present in Plato, tending to rank souls in view of prefixed criteria.
This leads to another point. I mean the one-dimensional character of such assumptions about reconciling experiences – there is no consideration of points of view. In the Republic, knowledge is argued to be independent of any perspective, while personal interests are harmful to the common good. Rather, everything depends on the absolute things (the Forms), even the value of talk exchanges. Philosophical conversation may degrade into a mere quarrel over quirks of language (eristic), rather than a genuinely dialectical exchange which involves the Forms (Rep. 454A1–B9). I wonder if for Plato, the experiences of the soul are abstract items; perhaps they are types that have their reality apart from any point of view. As far as I can see, the passages I have highlighted do not show that understanding the content of another's experience may require consideration of the point of view of the other.Footnote 17 For example, our twin experiences (representations) of hunger might differ in content on account of circumstantial factors pertaining to such experiences (your dieting, my forgetting to eat breakfast). Alternatively, our hungers might differ in content on account of slight differences in the individuation of our hungers, in spite of the similarities of our hunger experience considered as a type. Considering another's point of view pertaining to such experiences may be quite important for linguistic understanding.Footnote 18 It is true that several other factors that improve dialectical exchanges are noted in the dialogues, such as avoiding an unenlightened debate by maintaining fairness in argument (Tht. 167E–168B; Phlb. 17A), but points of view as a factor in experiences seem to be ignored.
In view of the ‘soul clarification’ strategy I have outlined, we are reminded that Socratic dialectic is not only based on constructing arguments from premises his interlocutor is supposed to accept for the conclusion Socrates wants to reach, at least in the Protagoras and the Gorgias.Footnote 19 Perhaps the strategy is meant for mature interlocutors who might find the protreptic approach somewhat puerile.
However, there are some complications to this picture, looking beyond the Protagoras and the Gorgias. One departure arises in the Euthydemus. Euthydemus requests a dialectical response from Socrates on the basis of partial understanding (dêpou ti … ho legô … pros touto toinun apokrinou ho hupolambaneis), although this only involves understanding a question (Eud. 295B2–C11). There is no sign here of aligning the experiences of the soul. Another possibility is suggested by the famous antadikein passage from the Crito (Crit. 49C10–E2).Footnote 20 Socrates divides those select individuals, who adhere to the revolutionary thesis that one should never do wrong in return (antadikein), and everyone else in the city.Footnote 21 The common ground (koinê boulê), namely, endorsing the ‘never reciprocate wrongdoing’ thesis, provides dialectical leverage.Footnote 22 It can lead to genuine dialectical progress, although the important value here is a shared belief, not an inner experience as in the Gorgias.Footnote 23 Finally, can ‘like experiences’ be habituated in the course of dialectical exchanges? It has been argued that the Aristotelian prospect of training the soul in response to dialectic is implicit in some dialogues (Phd. 89D–E; La. 194A1–B4; Men. 85C9–D1), but a program of training of divergent souls to conform to philosophical experiences and desires is not in view.Footnote 24 These are all interesting alternatives, but I must return to my main topic.
III
Now I will take up Gorgias. Gorgias is an intriguing figure on account of his role in Plato's Gorgias, his status in Antiquity as a leading light in the development of rhetoric, and his interest in language and psychology.Footnote 25 A highly condensed version of his most perplexing work, On What is Not, survives in a short Peripatetic treatise De Melisso, Xenophane, Gorgia (MXG), and in Sextus Empiricus' Adversus Mathematicos (Math. 7.65–87).Footnote 26 This work contains his famous arguments against being, knowledge, and communication. On the other hand, the psychological emphasis of the Encomium of Helen and the Defence of Palamedes is equally significant.
In brief, Gorgias' position provides a contrast to the psychological realism of the dialogues, by his apparent dismissal of the stable internal experiences and desires that are unearthed in the course of dialectical exchanges. Rather, experiences and desires are crafted by the techniques of rhetoric, which induce conviction in the soul (Helen 13–14; Plato, Men. 95C1–4). This leads to a strange paradox in the remains of Gorgias. Gorgias would deny that we can connect experiences. Communicating anything, including inner experiences, is impossible, since logos is different than what we speak about. ‘For that by which we communicate (mênuomen) is logos, but logos is not the realities and things that are (ta hupokeimena kai onta); we do not then communicate to others the things that are, but only logos, which is other than the realities’ (Math. 7.84). In other words, only logos can be produced by a speaker; other realities like noise or color are inaccessible to the soul apart from our faculties of hearing or sight (Math. 7.84–5; MXG 980a-b). All purported representations of such experiences must fail.Footnote 27 So then logos has the power to manufacture psychic experience, but psychic experience cannot be communicated. From this angle, the ‘soul clarification’ strategy in Plato redeems certain integral features of human nature from the toils of Gorgianic sophistry.
Admittedly, the outrageous arguments of On What is Not may present Gorgias' play with Eleatic techniques more than anything else.Footnote 28 This does not look like serious metaphysics. Some scholars have understood Gorgias as challenging the impersonal, rational authority of Parmenidean logos. Certainly, Parmenides' austere view of persuasion makes no allowance for the role of opinion and emotions that is so prominent in Gorgias (DK fr. 2, fr. 6–8). Gorgias' concept of logos disregards truth and knowledge, at least when compared to Plato. In addition to being cut off from its objects, logos is deceptive.Footnote 29 The values and goals of rhetoric run counter to Plato's concern with absolute standards, validated by the Forms. Short of this path to absolute truth and reality, things become rather murky and deceptive. It is by virtue of the intelligible realities that any logos attains some measure of truth, even if our logoi deal with objects that are at a remove from truth (cf. Tim. 29B1–D3).Footnote 30 Gorgias is not properly committed to a notion of falsehood (or truth) that depends on independent reality, while Plato envisions a sovereignty to the ultimate reality of things, which language use, employing imperfect images, should respect.Footnote 31
IV
In conclusion, I think Plato is dicing with Gorgias philosophically in the very dialogues which are most heavily concerned with forms of discourse. In the Gorgias (as well as the Symposium) the view is that speakers cannot understand alien experiences by conversation alone, even by the rigors of the Socratic elenchus. Unfortunately, there is no developed alternative model in the Platonic dialogues for accessing another's differing experiences. However, helpful clarifications of stable features of the soul are possible. The difficulties in bringing ‘philistine souls’ into Socratic alignment are the result of possessing an inferior soul, suffering misdirected passions, or missing the philosophy bug. It is not so much the intrinsic limitations of Socratic techniques – this would be the crux of the matter for Gorgias. For Gorgias, souls are infinitely malleable by technical discourse strategies, hence failure to win over hard cases would expose some shortcomings of Socratic logos. For my part, I take these frustrations in the dialogues more as explorations of character than as limitations of method. Perhaps it is possible to see Plato as finding a via media between the philosophical rigor of Parmenides and the playful opportunism of Gorgias.Footnote 32
