How to Persuade—With Ethos, Pathos, or Logos?

August 18, 2011, 11:00 am

AristotlePersuasion is at the root of most of what we do in the academy. This is most obvious for our research, which is often presented in the form of an argument intended to convince our discipline. Teaching is persuading students to take a topic seriously, to understand its questions and possible answers, and to put in the hard work of learning. Even service is an attempt to convince our colleagues and institutions to do this and not that.

It would behoove us, then, to learn something about persuasion. Let’s take a page from Aristotle’s Rhetoric:

Of the modes of persuasion furnished by the spoken word there are three kinds. The first kind depends on the personal character of the speaker; the second on putting the audience into a certain frame of mind; the third on the proof, or apparent proof, provided by the words of the speech itself.

These three modes of persuasion can be called respectively ethos (ἦθος—disposition or character), pathos (πάθος—emotion or passion), and logos (λόγος—argument or discourse). Aristotle elaborated on his definition of each of these types.

  • Ethos has to do with who you are and how you come across. Aristotle would include both the way in which you speak and your individual character or integrity in this category. As he wrote, “We believe good men more fully and more readily than others.” An example of an ethical appeal: “I’ve served at this university for 28 years”—an appeal from the speaker’s experience.
  • Pathos involves stirring up people’s emotions. It includes appeals to people’s pity, anger, fear, hope, and the like. An example of an emotional appeal: “For-profit colleges are destroying higher education”—as stated here, an appeal to the listener’s fears and values.
  • Logos is the use of argumentation. This category includes arguments, data, statistics, and all types of reasoning. An example of a logical appeal: “Research data demonstrates that students who have attended for-profit colleges have a much higher debt load than students at private or public colleges”—an appeal to statistics.

Which of these three modes of persuasion is most powerful?

Aristotle didn’t think much of the emotional appeal. He wrote, “The arousing of prejudice, pity, anger, and similar emotions has nothing to do with the essential facts, but is merely a personal appeal to the man who is judging the case.” He also spent little time on the ethical appeal. Instead he thought the logical appeal was the most important, because he conceived of rhetoric as related to dialectic. For Aristotle, the syllogism—specifically, the enthymeme–was the most effective form of persuasion.

In this assessment, the modern academy more or less concurs with the ancient Academy. Within this space, logos is given pride of place, with ethos second and pathos third if it would be considered legitimate at all.

Nevertheless, I think ethos is the primary mode of persuasion, and one which we neglect at our peril.

Reflect for a moment on how you have been persuaded. When you were a student, which teacher influenced you the most? Probably the one whose character and interaction with students you found most appealing. Which publications do you trust the most? Probably the ones with the best brand (branding being our impoverished substitute for ethos). Which scholars are the most persuasive? Not simply the ones who make the sharpest arguments, but the ones who have connections to other scholars. With which colleagues do you get the most done? Probably not the ones who come to committee meetings with binders full of statistics, but the ones with whom you are most friendly.

Even in the academy, where logical arguments are and should be privileged, the ethical argument is still the gateway to all other types of persuasion. Concerning argumentation, Aristotle wrote, “Argument based on knowledge implies instruction, and there are people whom one cannot instruct.” We should avoid applying the pessimism in the second half of that sentence to our students or colleagues. Still, the point remains that logical arguments require the audience to have a base of earlier teaching. Without first the appeal from ethos, you’re unlikely to be granted a hearing on logical grounds.

In short, being persuasive is fundamentally a matter of ethics. There is no part of your work as a scholar, teacher, and colleague that is not wrapped up in your character as a person. How you reply to students’ e-mails matters. The courtesy or discourtesy with which you treat your colleagues matters. The professionalism with which you comport yourself matters. How generous or not you are in scholarly debates matters. Whether or not you shoulder your share of the work matters.

These ethical considerations matter, in my opinion, not just because your ethos determines how effective you will be as a scholar, but because how you comport yourself as a scholar affects your ethos–who you are.

Aristotle made this point too. He distinguished between the virtuous rhetorician and the evil sophist, not by how skillful they were at persuasion, but by the moral purposes for which they attempted to persuade. The right use of ethos to persuade is a means to accomplishing our scholarly work. But our scholarly work is worth doing because it is an ethical pursuit.

What are you doing to be persuasive ethically? How are you succeeding? How are you falling short, and what could you do better?

    Interesting stuff, and I agree generally that ethos is under-rated. But the Greek is ἦθος “disposition, character” (http://stephanus.tlg.uci.edu/lsj/#eid=48062&context=lsj&action=from-search) not ἒθος. Not that they aren’t related.

  • http://lincolnmullen.com/ Lincoln Mullen

    Thanks for the correction, @chardy61! My Greek is obviously rusty.

  • patdolanatiowa

    I think that Aristotle left out a powerful persuasive mode: mythos. His sense of “mythos” gets articulated in the Poetics, where he uses it to designate the plot of a drama. If you look at how persuasion is accomplished, various culturally validated plots are key. For example, “If we lower marginal tax rates, economic activity will increase,” or, “if we educate people, discrimination will diminish,” are both very powerful, even in the face of disconfirming evidence. (I make no claims for the truth of either of these.)

    In contemporary discussions of political persuasion people commonly say, “So-and-so is attempting to control the narrative,” which I think points to the power of mythos in public advocacy.

    In the classroom, I try to get them to buy into the following mythos, “If you work hard at the things I ask you to do, you will develop as a writer, and grow as a learner.” Part of my ethos is that I obviously believe this mythos.

  • drnels

    It is because of “mythos” that I always emphasize the Sophists over Aristotle in my History of Rhetorical Theory course.  That and “nomos.”

  • translog

    Over 2300 years old, the Aristotlian logic still works magic in political and the birth of new movements such as Anna Hazare in India today. Please visit visual mapping of this concept now at http://schriftman.files.wordpress.com/2009/11/aristotle-constitutions-2.png

  • 2smj3

    I like the way Parker Palmer talked about what might be called ethos: “Good teaching cannot be reduced to technique; good teaching comes from the identity and integrity of the teacher.” 

  • jsclarkfl

    Great piece, and always nice to see classical rhetoric once again brought to bear on modern culture. I was always under the impression that Aristotle believed ethos to be the most powerful means (not necessarily the most important or best), though I can’t quote chapter and verse on that. I’d also chime in with Nels and resist the characterization of the Sophists as evil — something Aristotle picked up from Plato, who is unfortunately our most influential source of information about these itinerant speech-teachers (Aristophanes’ dismissal in Clouds stands out, too). If I am not too rusty on my antiquities, this antipathy emerges in part from then-contemporary arguments over whether the teaching of arete (~”excellence”) was possible, as many of the Sophists held, and the nomos-physis controversy, which could be said to foreshadow postmodernism and constructivism. So perhaps we still find the “good person, speaking well” (Quintilian) a reliable guide through the ontological and epistemological jungles.

  • willardhall

    Ethos is also my argument to my composition and literature students of why writing mechanics (spelling, punctuation, etc) really matter.  While mistakes in those things rarely impact meaning in student papers, they do undercut credibility dramatically.  If students don’t spell Hawthorne’s name correctly, why should I believe anything they write in their interpretations of “My Kinsman,…”? 

  • jefftylerpmp

    If only our news institutions would take this argument seriously. If only my graduate students would follow this line of reasoning. One cannot present a substantiated argument based on logic in 124 characters. One can present unsubstantiated argument based on emotion in 124 characters.

  • patdolanatiowa

    I apologize, but I’m an inveterate wiseacre and I can’t turn down a challenge:

    All men are mortal.
    Socrates is a man.
    Socrates is mortal.

    56 characters, including spaces.

  • Prof_truthteller

    How am I falling short? I wish I had better tools for countering the evil sophists.

  • jimmackin

    Ethos is primary.  Logos moves the argument forward if the audience finds one credible.  Pathos is necessary to motivate toward action.  One must also deal with pathos at times by suppressing it, as in encouraging students to develop critical distance in their analysis instead of relying on their gut reactions.  Good use of logos and pathos also contributes to the appeal to ethos.

  • mkennerly

    Ahh, Aristotle! Be still my rhetoric-loving heart!

    Though Aristotle is often pegged as favoring logos above all, jsclarkefl has it right on ethos: at Rhetoric 1.2.4.1356a, Aristotle avers that it is “almost, so to speak, the most authoritative form of persuasion.” (Kennedy inserted the “almost” for the second edition.) Aristotle also dwells thoroughly and with sensitivity (rather than dismissal) on pathos. He winces and finger-wags at rhetors who abuse appeals to emotion, but not at those who use them. If, as Aristotle supposes, the end of rhetoric is the production of judgment, and, as Aristotle also supposes, emotions impinge on judgment, then how could he not take them seriously?

    Lastly, what patdolantiowa calls mythos and believes Aristotle to have left out, Aristotle calls a different name: the enthymeme. This type of rhetorical reasoning is “the body of persuasion,” giving social shape and substance to claims and narratives. Enthymemes are chains of reasoning (typically based on probable premises) that a rhetor intentionally leaves incomplete, expecting her audience to fill in missing parts and thus to participate actively in the persuasion process (which Aristotle says gives an audience pleasure). Enthymemes are powered by endoxai (embedded communal opinions and outlooks) that constitute social norms and social knowledge. These are the “culturally validated plots” that patdolantiowa rightly mentions as essential to the rhetorical act.

    Thanks for letting a classical rhetoric fiend froth away!

  • http://lincolnmullen.com/ Lincoln Mullen

    Thanks very much, everyone, for the helpful clarifications of Aristotle’s meaning. I’m glad to have my amateur understanding made better by expert rhetoricians and classicists.

    Concerning sophistry, let me offer my own clarification. I do not mean to offer my own judgment on the historical Sophists; I describe them as “evil” only so far as Aristotle thought them to be so. I think the broader point, which is not that controversial, still stands: that the difference between right and wrong uses of persuasion is not primarily a question of skill, but of moral purpose.

  • dpmccain

    What a marvelous reading opportunity; thank you.  Although I no longer teach composition (which focuses on argument, and the Toulmin Model)…or is supposed to..Persuasion was one of my students’ favorite lessons as they learned to monitor the pathos in argument.  I recall  one student was pleading for a grade “adjustment” (in front of classmates)…several students began to almost  hiss….”pathos, pathos….and logical fallacies too,” It was evident that the student was “caught” and gave up her plea.

    This post reminded how much I miss teaching the course, but my expectations for critical thinking and skill (reading and writing) exceeded the ability of the majority of my students.  I have some fond memories of those students who took ethos, pathos, and logos…and blossomed.  The others…ick. 

  • drjeff

    Wow.  This is great!  But there is an interplay that I don’t see anyone discussing.

    How do we evaluate the Ethos of an action?  Using Pathos or Logos?

    So, for example, if I buy a Prius, using Pathos, you might judge me to be a wonderful person, setting an example by reducing my personal contribution to the Earth’s load of pollution. 

    Using Logos, you might judge me to be a preening narcissist, interested in looking good personally while off-shoring the huge pollution generated in building it (which will never be “repaid” in the car’s normal lifetime) to developing countries and multi-national corporations.

    Which is the “truth”?

    Teaching
    college students rhetoric has become a mountain of hidden steel-jawed traps
    created by the belief-based culture at large. Students “think” based
    on what they see in the world around them, which is basically argument driven
    by belief systems, not by facts. Deep news (PBS’s The News Hour; Frontline;
    Charlie Rose) is nothing they watch much less absorb. Headline news (almost all
    of the rest of the shows) is their feeder, if they have such. Churches preach
    (always a turnoff), and parents are largely indifferent or “at sea”
    in terms of what their kids learn. Thus teaching in academe lies in a world
    removed, so far as to disappear into the horizon line. It becomes artificial,
    that is, inapplicable to practical ( the “really important”) issues.

     

     Even
    the more ordinary workplace has developed into tasks by committee, where only
    rarely are people required to pursue ideas and innovations. Most don’t have
    professions, they have jobs, which by definition do not stretch human
    capacities, but capitalize for employers a bet that people have
    “skills.” Sometimes the jobs are far more interesting for certain
    personalities. At higher levels, they are often more lucrative. Yet we have
    people who starve for routine jobs, unable and unwilling to take the risks of
    running a business that will “take too much out” of them. 

     

    The work
    ethic is an ethic. Working diligently and creatively is an ethic. Working
    independently is too. One’s ethos is in trouble when there’s no
    “audience” to see it. Yet it is everything. Out of ethos comes drive,
    stamina, the run for the top of the mountain, and thus the avoidance of the
    steel teeth that line life’s mouth. Just getting people (students and workers,
    parents and children) to think and taste “ethos” has become a much
    needed commodity, especially in the face of all the viciousness of current
    public debate, a thing usually devoid ethos because devoid of logos and so full
    of pathos, a swampy bog of mind. Pilgrim’s journey is our larger gambit today
    and so comprehensible now.

  • hvaline

       Aristotle’s discourse/formula on persuasion  supports the efficacy of education and the ethical pursuit of the practicalities/numbers of admissions departments.  Go Greeks!

  • dougharris

    Being only a mathematician I always thought we should use logos because it would violate ethos to do otherwise!

  • maxbini

    Recall Aristotle’s definitions of human being as ζώον λόγον έχον and ζώον πολιτικον (think of this not just as the rational animal but jointly as social, political and language user as well) and how this relates to seeking excellence and virtue (ἀρετή) and εὐδαιμονία (poorly translated as ‘happiness’).

    Everything expressed is marked by varying degrees of all three “types” – ethos, pathos and logos – admittedly sometimes positively and often negatively.

    I have come to believe that the style of expression chosen in a discussion is itself an argument – that arguments also have character.  The Romans (I am thinking of Seneca and Lucretius especially but believe that the argument should be extended to Cicero, Virgil, Horace, Ovid … (who to leave out?)) made interesting advances on the Greeks on this score.

    I’m reminded why I’m drawn to philosophy and philosophers. Thank you for the discussion of ethos, pathos, and logos. Let me offer what I do professionally to be persuasive ethically, though in practice I can’t separate ethos, pathos, and logos. Whether what I do works is yet to be seen, though it is clear that some folks would like to sneak a dose of Hemlock in my drink.
     
    I’m proposing A General Theory to Test Social Reality—the reliability—of institutions’ and leaders’ behavior vis-à-vis their institution’s and their representations. That is, do they, we, keep our promises? Administrators’ and leaders’ power to influence our daily lives deserves scrutiny and, if not in compliance with their organization’s and their representations, should be challenged.
     
    A form of inference for testing social reality is:
    R –> O
    ~O
    Therefore, ~R,
    where R is an institution’s representation of mission, goal, principle, policy, procedure, code of ethics, or rule and O is observation of a leader’s or institution’s behavior that reflects on its representation. (“—>” is read as If R, then O. Tilde, “~”, indicates negation.) The form of inference structures valid reasoning—if the premises are true, i.e., well-justified, so too is the conclusion.
     
    If the AACSB (accreditor of business colleges) is a reliable authority on academic quality, then it complies with, and persuades its members to comply with, its standards and advice.
     
    The AACSB complies with, and persuades its members to comply with, its standards and advice. (The evidence offered in the research demonstrates that this proposition is false.)
     
    Therefore, the AACSB is not a reliable authority on academic quality.

    Dear Mr. Mullen:

         I sincerely thank you for bringing Aristotle to public attention, even when that public consists of academic people.  In my own field (English composition) he is sometimes nodded to but not taken seriously in this age that Susan Jacoby calls “the age of American unreason.”.

         I agree with you, of course, that ethos is truly important and even that it is essential.  (I also think pathos is a legitimate and useful appeal, despite its widespread unethical use in our society.)

         However, I do agree with Aristotle that logos is the most important appeal.  It goes hand in hand with ethos, and is needed for reasoning in ethics.  When I look at the comments made by politicians currently running for public office, the major deficiency seems to be in logos.

         Thanks again.

    Sincerely,

    Richard Mezo

    “Ethics” is often a 50 cent word for ideology, along with the boatload of assumptions, preconceived notions and rationalizations that usually accompany it.  “Ethical behavior,” for example, is rarely outside the ideological shell that organizes our lives.  To “ethically persuade” young people is almost always to lead them into the acceptance of some sort of ideological frame, whereas to logically persuade them is — and should be — to inculcate a qualified immunity to ideological thinking.
     
    Part of this tendency is because ideology is what young people are usually looking for anyway.  Ralph K. White, in Nobody Wanted War, defined it thusly:  “Ideology…gives significance to the lives of individuals who might otherwise be overwhelmed by a sense of purposelessness and insignificance.  Usually some kind of black-and-white picture is an inherent part of the ideology, and gives meaning to the struggle between the good guys and the bad guys…”  (Knopf, 1970).  Hence “ethical persuasion” as it is practiced usually provides a paradigm for thinking in these terms:  the good guys share our ethics and the bad guys do not.  It is also primarily emotional and not intellectual.  A better name, and one used more freely outside of western society, is propaganda

    In my area, I have seen dozens of young teachers get their masters degree through a very “respectable”  and “face to face” university that offers a cohort program. They begin together and work for about 18 months in classes that meet one evening a week, and end up with a masters. The real joke is that as long as you pay the tuition and attend class, you will get your degree.  When I was teaching in a k-12 environment, I would often hear these masters students bragging in the teachers’ lounge about how easy the program was.  They did “group” projects for almost every class. Everyone passed, regardless of how much effort actually went into the program.

     However, this experience would lead me to brand all face to face cohort programs as a joke.  The real value lies in the student. Lazy students will cheat and slide through any environment. Honest students who want to prepare for a good career will do the work in any environment.

  • iheartpedagogy

    I understand where you’re coming from, NYBound. My experience with the online classes I’ve taken in the past was “meh”. Now prepare thineself for my über-long response—apologies for the verbosity. Know that I have smacked my own hand.

    I am currently a student in the MAT-TESOL@USC program and have found nothing “meh” about it. Students in the 1 year+ long program must attend weekly, synchronous classes via web conference in which we are required to participate in class discussions using a webcam and phone or VoIP. 

    I am a full-time student taking four classes presently: one held every Wednesday from 530am to 730am, another on the same day from 530pm to 8pm, and 2 on Saturdays that, together, run from 9am to 1pm. I also happen to be one of the few students in the program working full-time and, like those of my counterparts who also juggle work, homework, student teaching, and classes, have found it an incredibly tough slog. 

    In addition to class time and, of course, homework, we have student teaching requirements which are coordinated by 2tor and verified by the same, as well as by video recordings of our classroom teaching that are then analyzed in study group sessions and in class. As a related aside, I teach ESL after work, weekly at a local library. Student teaching not only allows us to practice the theories we learn in the program, but also gives us an environment in which to implement our Action Research Project (ARP), a capstone project designed in our last two terms. One among us is entering her ARP results in a CATESOL competition. Another was recently accepted to the University of New Mexico’s linguistics doctoral program.

    As if the student teaching requirement weren’t enough to cause your average grad student to rip their hair out, I’d say that approximately 75% of all of our classes have required weekly study group sessions which must be coordinated among group members who may reside in locations as disparate as Turkey, Korea, Des Moines, Iowa… These sessions are also held via a combination of web conference, webcam, VoIP/teleconference, are recorded, and are included in our participation grade.

    Ok, I’ve said a mouthful and then some! My ultimate point is that USC’s online program is a rigorous, demanding, interactive one. So rigorous that there have been numerous times that I wanted to give up and some in my cohort chose to do just that. So demanding that I often thought I would have had fewer demands on my time had I elected to complete, say, a communications or even an MBA program at a local university (something I considered before deciding upon the MAT@USC). So interactive that I have made close friends in the program with whom I’ve shared many a phone call, IM, Facebook message, email, and text message to clarify assignment requirements, share tips on job opportunities, complain about our nonexistent social lives and, more recently, to chat about meeting up at commencement or flying out to meet each other sometime soon.

    So that’s my experience. I think it all sounds not at all like what folks think of when they hear the term “online degree program” but I readily admit that I’m biased. ;)
