Love is often censured as a form of madness, yet not all madness is evil. There is a madness which is simple degeneracy, but on the other hand there are kinds of madness which are really forms of inspiration, from which come the greatest gifts conferred on man. Prophecy is a kind of madness, and so too is poetry. “The poetry of the sane man vanishes into nothingness before that of the inspired madman.” Mere sanity, which is of human origin, is inferior to that madness which is inspired by the gods and which is a condition for the highest kind of achievement. In this category goes the madness of the true lover. His is a generous state which confers blessings to the ignoring of self, whereas the conduct of the non-lover displays all the selfishness of business: “the affection of the non-lover, which is alloyed with mortal prudence and follows mortal and parsimonious rules of conduct will beget in the beloved soul the narrowness which common folk praise as virtue; it will cause the soul to be a wanderer upon the earth for nine thousand years and a fool below the earth at last.” It is the vulgar who do not realize that the madness of the noble lover is an inspired madness because he has his thoughts turned toward a beauty of divine origin.
Now the attitude of the noble lover toward the beloved is in direct contrast with that of the evil lover, who, as we have seen, strives to possess and victimize the object of his affections. For once the noble lover has mastered the conflict within his own soul by conquering appetite and fixing his attention upon the intelligible and the divine, he conceives an exalted attitude toward the beloved. The noble lover now “follows the beloved in reverence and awe.” So those who are filled with this kind of love “exhibit no jealousy or meanness toward the loved one, but endeavor by every means in their power to lead him to the likeness of the god whom they honor.” Such is the conversion by which love turns from the exploitative to the creative.
Here it becomes necessary to bring our concepts together and to think of all speech having persuasive power as a kind of “love.”[7] Thus, rhetorical speech is madness to the extent that it departs from the line which mere sanity lays down. There is always in its statement a kind of excess or deficiency which is immediately discernible when the test of simple realism is applied. Simple realism operates on a principle of equation or correspondence; one thing must match another, or, representation must tally with thing represented, like items in a tradesman’s account. Any excess or deficiency on the part of the representation invokes the existence of the world of symbolism, which simple realism must deny. This explains why there is an immortal feud between men of business and the users of metaphor and metonymy, the poets and the rhetoricians.[8] The man of business, the narrow and parsimonious soul in the allusion of Socrates, desires a world which is a reliable materiality. But this the poet and rhetorician will never let him have, for each, with his own purpose, is trying to advance the borders of the imaginative world. A primrose by the river’s brim will not remain that in the poet’s account, but is promptly turned into something very much larger and something highly implicative. He who is accustomed to record the world with an abacus cannot follow these transfigurations; and indeed the very occurrence of them subtly undermines the premise of his business. It is the historic tendency of the tradesman, therefore, to confine passion to quite narrow channels so that it will not upset the decent business arrangements of the world. But if the poet, as the chief transformer of our picture of the world, is the peculiar enemy of this mentality, the rhetorician is also hostile when practicing the kind of love proper to him. The “passion” in his speech is revolutionary, and it has a practical end.
We have now indicated the significance of the three types of lovers; but the remainder of the Phaedrus has much more to say about the nature of rhetoric, and we must return to one or more points to place our subject in a wider context. The problem of rhetoric which occupied Plato persistently, not only in the Phaedrus but also in other dialogues where this art is reviewed, may be best stated as a question: if truth alone is not sufficient to persuade men, what else remains that can be legitimately added? In one of the exchanges with Phaedrus, Socrates puts the question in the mouth of a personified Rhetoric: “I do not compel anyone to learn to speak without knowing the truth, but if my advice is of any value, he learns that first and then acquires me. So what I claim is this, that without my help the knowledge of the truth does not give the art of persuasion.”
Now rhetoric as we have discussed it in relation to the lovers consists of truth plus its artful presentation, and for this reason it becomes necessary to say something more about the natural order of dialectic and rhetoric. In any general characterization rhetoric will include dialectic,[9] but for the study of method it is necessary to separate the two. Dialectic is a method of investigation whose object is the establishment of truth about doubtful propositions. Aristotle in the Topics gives a concise statement of its nature. “A dialectical problem is a subject of inquiry that contributes either to choice or avoidance, or to truth and knowledge, and that either by itself, or as a help to the solution of some other such problem. It must, moreover, be something on which either people hold no opinion either way, or the masses hold a contrary opinion to the philosophers, or the philosophers to the masses, or each of them among themselves.”[10] Plato is not perfectly clear about the distinction between positive and dialectical terms. In one passage[11] he contrasts the “positive” terms “iron” and “silver” with the “dialectical” terms “justice” and “goodness”; yet in other passages his “dialectical” terms seem to include categorizations of the external world. Thus Socrates indicates that distinguishing the horse from the ass is a dialectical operation;[12] and he tells us later that a good dialectician is able to divide things by classes “where the natural joints are” and will avoid breaking any part “after the manner of a bad carver.”[13] Such, perhaps, is Aristotle’s dialectic which contributes to truth and knowledge.
But there is a branch of dialectic which contributes to “choice or avoidance,” and it is with this that rhetoric is regularly found joined. Generally speaking, this is a rhetoric involving questions of policy, and the dialectic which precedes it will determine not the application of positive terms but that of terms which are subject to the contingency of evaluation. Here dialectical inquiry will concern itself not with what is “iron” but with what is “good.” It seeks to establish what belongs in the category of the “just” rather than what belongs in the genus Canis. As a general rule, simple object words such as “iron” and “house” have no connotations of policy, although it is frequently possible to give them these through speech situations in which there is added to their referential function a kind of impulse. We should have to interpret in this way “Fire!” or “Gold!” because these terms acquire something through intonation and relationship which places them in the class of evaluative expressions.
Any piece of persuasion, therefore, will contain as its first process a dialectic establishing terms which have to do with policy. Now a term of policy is essentially a term of motion, and here begins the congruence of rhetoric with the soul which underlies the speculation of the Phaedrus. In his myth of the charioteer, Socrates declares that every soul is immortal because “that which is ever moving is immortal.” Motion, it would appear from this definition, is part of the soul’s essence. And just because the soul is ever tending, positive or indifferent terms cannot partake of this congruence. But terms of tendency—goodness, justice, divinity, and the like—are terms of motion and therefore may be said to comport with the soul’s essence. The soul’s perception of goodness, justice, and divinity will depend upon its proper tendency, while at the same time contacts with these in discourse confirm and direct that tendency. The education of the soul is not a process of bringing it into correspondence with a physical structure like the external world, but rather a process of rightly affecting its motion. By this conception, a soul which is rightly affected calls that good which is good; but a soul which is wrongly turned calls that good which is evil. What Plato has prepared us to see is that the virtuous rhetorician, who is a lover of truth, has a soul of such movement that its dialectical perceptions are consonant with those of a divine mind. Or, in the language of more technical philosophy, this soul is aware of axiological systems which have ontic status. The good soul, consequently, will not urge a perversion of justice as justice in order to impose upon the commonwealth. Insofar as the soul has its impulse in the right direction, its definitions will agree with the true nature of intelligible things.
There is, then, no true rhetoric without dialectic, for the dialectic provides that basis of “high speculation about nature” without which rhetoric in the narrower sense has nothing to work upon. Yet, when the disputed terms have been established, we are at the limit of dialectic. How does the noble rhetorician proceed from this point on? That the clearest demonstration in terms of logical inclusion and exclusion often fails to win assent we hardly need state; therefore, to what does the rhetorician resort at this critical passage? It is the stage at which he passes from the logical to the analogical, or it is where figuration comes into rhetoric.
To look at this for a moment through a practical illustration, let us suppose that a speaker has convinced his listeners that his position is “true” as far as dialectical inquiry may be pushed. Now he sets about moving the listeners toward that position, but there is no way to move them except through the operation of analogy. The analogy proceeds by showing that the position being urged resembles or partakes of something greater and finer. It will be represented, in sum, as one of the steps leading toward ultimate good. Let us further suppose our speaker to be arguing for the payment of a just debt. The payment of the just debt is not itself justice, but the payment of this particular debt is one of the many things which would have to be done before this could be a completely just world. It is just, then, because it partakes of the ideal justice, or it is a small analogue of all justice (in practice it will be found that the rhetorician makes extensive use of synecdoche, whereby the small part is used as a vivid suggestion of the grandeur of the whole). It is by bringing out these resemblances that the good rhetorician leads those who listen in the direction of what is good. In effect, he performs a cure of souls by giving impulse, chiefly through figuration, toward an ideal good.
