2300 years ago, Aristotle wrote down the secret to being a persuasive speaker, the secret which forms the basis for nearly every public speaking book written since then.

Do you know the secret?

If you don’t, you might be wondering what a 2300-year-old theory has to do with public speaking in the year 2010.

In a word — everything!

In this article, you’ll learn what ethos, pathos, and logos are (the secret!), and what every speaker needs to understand about these three pillars of public speaking.

What are Ethos, Pathos, and Logos?

So, what are ethos, pathos, and logos?

In simplest terms, they correspond to:

• Ethos: credibility (or character) of the speaker
• Pathos: emotional connection to the audience
• Logos: logical argument

Together, they are the three persuasive appeals. In other words, these are the three essential qualities that your speech or presentation must have before your audience will accept your message.

Origins of Ethos, Pathos, Logos — On Rhetoric by Aristotle

Written in the 4th century B.C.E., the Greek philosopher Aristotle compiled his thoughts on the art of rhetoric into On Rhetoric, including his theory on the three persuasive appeals.

Many teachers of communication, speech, and rhetoric consider Aristotle’s On Rhetoric to be a seminal work in the field. Indeed, the editors of The Rhetoric of Western Thought: From the Mediterranean World to the Global Setting call it “the most important single work on persuasion ever written.” It is hard to argue this claim; most advice from modern books can be traced back to Aristotle’s foundations.

Ethos

Before you can convince an audience to accept anything you say, they have to accept you as credible.

There are many aspects to building your credibility:

• Does the audience respect you?
• Does the audience believe you are of good character?
• Does the audience believe you are generally trustworthy?
• Does the audience believe you are an authority on this speech topic?

Keep in mind that it isn’t enough for you to know that you are a credible source. (This isn’t about your confidence, experience, or expertise.) Your audience must know this. Ethos is your level of credibility as perceived by your audience.

We will define ethos in greater detail, and we will study examples of how to establish and build ethos.

Pathos

Pathos is the quality of a persuasive presentation which appeals to the emotions of the audience.

• Do your words evoke feelings of … love? … sympathy? … fear?
• Do your visuals evoke feelings of compassion? … envy?
• Does your characterization of the competition evoke feelings of hate? contempt?

Emotional connection can be created in many ways by a speaker, perhaps most notably by stories. The goal of a story, anecdote, analogy, simile, and metaphor is often to link an aspect of our primary message with a triggered emotional response from the audience.

We will study pathos in greater detail, and look at how to build pathos by tapping into different audience emotions.

Logos

Logos is synonymous with a logical argument.

• Does your message make sense?
• Is your message based on facts, statistics, and evidence?
• Will your call-to-action lead to the desired outcome that you promise?

We will see why logos is critical to your success, and examine ways to construct a logical, reasoned argument.

Which is most important? Ethos? Pathos? or Logos?

Suppose two speakers give speeches about a new corporate restructuring strategy.

• The first speaker — a grade nine student — gives a flawless speech pitching strategy A which is both logically sound and stirs emotions.
• The second speaker — a Fortune 500 CEO — gives a boring speech pitching strategy B.

Which speech is more persuasive? Is the CEO’s speech more persuasive, simply because she has much more credibility (ethos)?

Some suggest that pathos is the most critical of the three. In You’ve Got to Be Believed to Be Heard, Bert Decker says that people buy on emotion (pathos) and justify with fact (logos). True? You decide.

Aristotle believed that logos should be the most important of the three persuasive appeals. As a philosopher and a master of logical reasoning, he believed that logos should be the only required persuasive appeal. That is, if you demonstrated logos, you should not need either ethos or pathos.

However, Aristotle stated that logos alone is not sufficient. Not only is it not sufficient on its own, but it is no more important than either of the two other pillars. He argued that all three persuasive appeals are necessary.

Is he right? What do you think?

Next in this Series…

In the next article of this series, we examine ethos in greater detail.

Do you think you are easily persuaded? If you are like most people, you aren’t swayed easily to change your mind about something. Persuasion is difficult because changing views often makes people feel like they were either not informed or ill-informed, which also means they have to admit they were wrong about something. We will learn about nine persuasive strategies that you can use to more effectively influence audience members’ beliefs, attitudes, and values. They are ethos, logos, pathos, positive motivation, negative motivation, cognitive dissonance, appeal to safety needs, appeal to social needs, and appeal to self-esteem needs.  In this excerpt, we will learn about ethos.

Ethos, logos, and pathos were Aristotle’s three forms of rhetorical proof, meaning they were primary to his theories of persuasion. Ethos refers to the credibility of a speaker and includes three dimensions: competence, trustworthiness, and dynamism. The two most researched dimensions of credibility are competence and trustworthiness (Stiff & Mongeau, 2003).

Competence refers to the perception of a speaker’s expertise in relation to the topic being discussed. A speaker can enhance their perceived competence by presenting a speech based in solid research and that is well organized and practiced. Competent speakers must know the content of their speech and be able to effectively deliver that content. Trustworthiness refers to the degree that audience members perceive a speaker to be presenting accurate, credible information in a nonmanipulative way. Perceptions of trustworthiness come from the content of the speech and the personality of the speaker. In terms of content, trustworthy speakers consider the audience throughout the speech-making process, present information in a balanced way, do not coerce the audience, cite credible sources, and follow the general principles of communication ethics. In terms of personality, trustworthy speakers are also friendly and warm (Stiff & Mongeau, 2003).

Dynamism refers to the degree to which audience members perceive a speaker to be outgoing and animated (Stiff & Mongeau, 2003). Two components of dynamism are charisma and energy. Charisma refers to a mixture of abstract and concrete qualities that make a speaker attractive to an audience. Charismatic people usually know they are charismatic because they’ve been told that in their lives, and people have been attracted to them. The dynamism of the speaker can also be seen through their demonstration of goodwill toward the audience, or whether they have the audience's best interests at heart.

Unfortunately, charisma is difficult to intentionally develop, and some people seem to have a naturally charismatic personality, while others do not. Even though everyone can’t embody the charismatic aspect of dynamism, the other component of dynamism, energy, is something that everyone can tap into. Communicating enthusiasm for your topic and audience by presenting relevant content and using engaging delivery strategies such as vocal variety and eye contact can increase your dynamism.

Speakers should strive to appeal to ethos, logos, and pathos within a speech. A speech built primarily on ethos might lead an audience to think that a speaker is full of himself or herself. 

Review of Ethos

1. Ethos relates to the credibility of a speaker. Speakers develop ethos by
   • appearing competent, trustworthy, and dynamic;
   • sharing their credentials and/or relevant personal experience;
   • presenting a balanced and noncoercive argument;
   • citing credible sources;
   • using appropriate language and grammar;
   • being perceived as likable; and
   • appearing engaged with the topic and audience through effective delivery.

Identifying Persuasive Strategies in Mary Fisher’s “Whisper of AIDS” Speech

Mary Fisher’s speech at the 1992 Republican National Convention, “A Whisper of AIDS,” is one of the most moving and powerful speeches of the past few decades. She uses, more than once, all the persuasive strategies discussed in this chapter. The video and transcript of her speech can be found on the American Rhetoric website (www.americanrhetoric.com/speeches/maryfisher1992rnc.html). As you watch the speech, answer the following questions:
