According to Aristotle, a successful persuasive speaker will use either ethos (emotional appeal), logos (appeal based on reason), or pathos (appeal of the speaker) in order to get his or her point across. Since Chaucer was a highly educated writer, it is reasonable that he would have been familiar with the works of Aristotle. In fact, in Chaucer’s Troilus and Criseyde, both Troilus’s and Diomede’s initial proposals to Criseyde utilize opposing rhetorical techniques. While Troilus’s proposal appeals to Criseyde’s emotional side with ethos, Diomede’s appeals to her sense of reason with logos.
Found in Book III, Troilus’s original proposal to Criseyde is based almost entirely on emotional appeal. Troilus’s behavior seems to have been devised to make him look weak and pitiful so Criseyde would feel sorry for him and accept. As soon as Criseyde enters his room where he is bedridden, Troilus announces, “Allas, I may not rise, To knele and do yow honor in some wyse,” or basically that he is too helpless to sit up (Book III, 69-70). This would be more forgivable if Troilus had an actual illness besides lovesickness, but he makes it clear to Helen and his brother Deiphebus that his pain is “by cause, lo, that she a lady is” (Book II, 1633). When Troilus instead tries to woo Criseyde with the speech Pandarus wrote for him, he finds that: “And sire, his lessoun, that he wende koun To preyen hire, is thorugh his wit ironne” (Book III, 83-84). All Troilus can do then is stammer and “wex sodeynliche red,” emotional appeal in itself because it invokes pity on Criseyde’s part, as she was no fool and “al this aspied wel ynough” (82, 85). The words he does end up saying all focus on his suffering. In fact his first words to her are “Mercy, mercy, swete herte!” to make it clear to her that she is the cause of his pain (98). He implies that his end is near, “Now recche I nevere how soone that I deye” (112). By this point, Pandarus is reacting emotionally to his appeal, and he “wep as he to water wolde” (115). But not until Criseyde’s prying does Troilus stop his complaining to reveal his intent: “In trouthe alwey to don yow my servise” (133). In this proposal, invoking an emotional reaction was more important than conveying a point. This proposal is half successful, because while Criseyde does “receyven him fully to [her] servyse,” she feels a need to point out the logical flaws in their union:
“But natheles, this warne I yow,” quod she
A kynges sone although ye be, ywys,
Ye shal namore han sovereignete
Of me in love, than right in that cas is;”
Criseyde makes sure to stress that she is not giving away her whole person to Troilus while at the same time underlining their difference in status. Criseyde’s speech makes clear that Troilus’s emotional speech was intent on evoking emotions onto a blank slate of a person, not on adding to any concerns Criseyde might have already held. Therefore, Troilus’s idea of rhetoric is like that of the Greek Sophists: speech was considered a dramatic “spectacle” designed for performance, not for proving a point. Troilus’s theatrical behavior and use of ethos does just this.
Meanwhile, Diomede’s original proposal to Criseyde is designed to appeal to her logical reasoning. To assess it, it is best to begin before he actually speaks to Criseyde, during his calculating preparation of the speech. When it is time for Criseyde to be traded to the Greeks, Diomede is aware that Criseyde has feelings for Troilus since as soon as she parts with him, “Ful sorfully she sighte, and seyde “Allas!… And forth she rit ful sorwfully a pas” (Book V, 58, 61). As he leads her horse away, he thinks to himself “Al my labour shal nat ben on ydel” and that he must wait to give his proposal at the correct time since she presumably “have in hire thought Hym that I gesse” (94, 102-103). It is clear that his sense of reason is at work even in his timing. When he does begin to speak, he first tries to relax her since she is upset, and she would be more likely to listen in a better mood. He says, “A Grek ye sholde among us alle fynde As any Troian is, and ek as kynde” (125-126). Though the Greeks are at war with the Trojans, Diomede realizes Criseyde’s feelings of nationalism and plays into her sympathies. Though he may not himself agree that the Trojans are in any way as good as the Greeks, he insists to Criseyde that they are hardly different, and “For though ye Troians with us Grekes wrothe… O god of Love in soth we serven bothe” (141, 143). Next, he flatters Criseyde with the intent of reviving her spirits: “Thus seyde I nevere er now to womman born… I loved never womman here-biforn” (155, 157). While Diomede’s admittance here is more hyperbolic than believable, it is exactly what a lady like Criseyde would expect to hear. He also states “Ther ben so worthi knyghtes in this place, And ye so fayr, that everich of hem alle Wol peynen hym to stonden in youre grace” to lay it on even thicker (169-171). Finally, like the final brick on top of a pyramid, Diomede requests simply to serve her: “That ye me for youre servant wolde calle, So lowly ne so trewely yow serve” (173-174). Unlike Troilus’s request to serve Criseyde, Diomede’s request utilizes all the elements he has already built up in his speech, like the conclusion to a point, whereas Troilus’s sounded more like an afterthought behind a performance. However, it is clear in Criseyde’s response that Diomede lacked ethos, since “she naught his tales herde But here and ther, now here a word or two” (179-180). If Diomede’s speech had been more dramatic, Criseyde would have felt more obliged to give a fitting response. Still, Diomede’s consideration of Criseyde’s previous feelings and use of rhetorical tools like flattery and hyperbole betray the logical workings within his speech.
In Chaucer’s Troilus and Criseyde, two romantic proposals are made to Criseyde during the course of the story. The first, by Troilus, utilizes ethos to persuade her, and the second, by Diomede, makes use of logos to appeal to her. Which of these two speeches was more successful? Ultimately, both led to the speaker gaining Criseyde’s interest. However, I would have to suggest that Diomede’s speech, focused on logical reasoning, is more successful in the long run. While both speeches used techniques that would have been approved by Aristotle, the ancient Greek philosopher stresses that the speaker must be aware of “all the available means of persuasion” and which type would be most appropriate. We already know from Book II that Criseyde considers herself a reasonable, independent actor: “I am myn owene womman, wel at ese” (Book II, 750). Therefore, Diomede was a better judge of character in deciding which rhetorical tools to use to win over Criseyde.
