There are three types of rhetorical appeals, or persuasive strategies, used in arguments to support claims and respond to opposing arguments. A good argument will generally use a combination of all three appeals to make its case.

Logos

Logos or the appeal to reason relies on logic or reason. Logos often depends on the use of inductive or deductive reasoning.

Inductive reasoning takes a specific representative case or facts and then draws generalizations or conclusions from them. Inductive reasoning must be based on a sufficient amount of reliable evidence. In other words, the facts you draw on must fairly represent the larger situation or population. Example:

Fair trade agreements have raised the quality of life for coffee producers, so fair trade agreements could be used to help other farmers as well.

In this example the specific case of fair trade agreements with coffee producers is being used as the starting point for the claim. Because these agreements have worked the author concludes that it could work for other farmers as well.

Deductive reasoning begins with a generalization and then applies it to a specific case. The generalization you start with must have been based on a sufficient amount of reliable evidence.Example:

Genetically modified seeds have caused poverty, hunger, and a decline in bio-diversity everywhere they have been introduced, so there is no reason the same thing will not occur when genetically modified corn seeds are introduced in Mexico.

In this example the author starts with a large claim, that genetically modified seeds have been problematic everywhere, and from this draws the more localized or specific conclusion that Mexico will be affected in the same way.

Avoid Logical Fallacies

These are some common errors in reasoning that will undermine the logic of your argument. Also, watch out for these slips in other people's arguments.

Slippery slope: This is a conclusion based on the premise that if A happens, then eventually through a series of small steps, through B, C,..., X, Y, Z will happen, too, basically equating A and Z. So, if we don't want Z to occur A must not be allowed to occur either. Example:

If we ban Hummers because they are bad for the environment eventually the government will ban all cars, so we should not ban Hummers.

In this example the author is equating banning Hummers with banning all cars, which is not the same thing.

Hasty Generalization: This is a conclusion based on insufficient or biased evidence. In other words, you are rushing to a conclusion before you have all the relevant facts. Example:

Even though it's only the first day, I can tell this is going to be a boring course.

In this example the author is basing their evaluation of the entire course on only one class, and on the first day which is notoriously boring and full of housekeeping tasks for most courses. To make a fair and reasonable evaluation the author must attend several classes, and possibly even examine the textbook, talk to the professor, or talk to others who have previously finished the course in order to have sufficient evidence to base a conclusion on.

Post hoc ergo propter hoc: This is a conclusion that assumes that if 'A' occurred after 'B' then 'B' must have caused 'A.' Example:

I drank bottled water and now I am sick, so the water must have made me sick.

In this example the author assumes that if one event chronologically follows another the first event must have caused the second. But the illness could have been caused by the burrito the night before, a flu bug that had been working on the body for days, or a chemical spill across campus. There is no reason, without more evidence, to assume the water caused the person to be sick.

Genetic Fallacy: A conclusion is based on an argument that the origins of a person, idea, institute, or theory determine its character, nature, or worth. Example:

The Volkswagen Beetle is an evil car because it was originally designed by Hitler's army.

In this example the author is equating the character of a car with the character of the people who built the car.

Begging the Claim: The conclusion that the writer should prove is validated within the claim. Example:

Filthy and polluting coal should be banned.

Arguing that coal pollutes the earth and thus should be banned would be logical. But the very conclusion that should be proved, that coal causes enough pollution to warrant banning its use, is already assumed in the claim by referring to it as "filthy and polluting."

Circular Argument: This restates the argument rather than actually proving it. Example:

George Bush is a good communicator because he speaks effectively.

In this example the conclusion that Bush is a "good communicator" and the evidence used to prove it "he speaks effectively" are basically the same idea. Specific evidence such as using everyday language, breaking down complex problems, or illustrating his points with humorous stories would be needed to prove either half of the sentence.

Either/or: This is a conclusion that oversimplifies the argument by reducing it to only two sides or choices. Example:

We can either stop using cars or destroy the earth.

In this example where two choices are presented as the only options, yet the author ignores a range of choices in between such as developing cleaner technology, car sharing systems for necessities and emergencies, or better community planning to discourage daily driving.

Ad hominem: This is an attack on the character of a person rather than their opinions or arguments. Example:

Green Peace's strategies aren't effective because they are all dirty, lazy hippies.

In this example the author doesn't even name particular strategies Green Peace has suggested, much less evaluate those strategies on their merits. Instead, the author attacks the characters of the individuals in the group.

Ad populum: This is an emotional appeal that speaks to positive (such as patriotism, religion, democracy) or negative (such as terrorism or fascism) concepts rather than the real issue at hand. Example:

If you were a true American you would support the rights of people to choose whatever vehicle they want.

In this example the author equates being a "true American," a concept that people want to be associated with, particularly in a time of war, with allowing people to buy any vehicle they want even though there is no inherent connection between the two.

Red Herring: This is a diversionary tactic that avoids the key issues, often by avoiding opposing arguments rather than addressing them. Example:

The level of mercury in seafood may be unsafe, but what will fishers do to support their families.

In this example the author switches the discussion away from the safety of the food and talks instead about an economic issue, the livelihood of those catching fish. While one issue may effect the other, it does not mean we should ignore possible safety issues because of possible economic consequences to a few individuals.

Ethos

Ethos or the ethical appeal is based on the character, credibility, or reliability of the writer. There are many ways to establish good character and credibility as an author:

  • Use only credible, reliable sources to build your argument and cite those sources properly.
  • Respect the reader by stating the opposing position accurately.
  • Establish common ground with your audience. Most of the time, this can be done by acknowledging values and beliefs shared by those on both sides of the argument.
  • If appropriate for the assignment, disclose why you are interested in this topic or what personal experiences you have had with the topic.
  • Organize your argument in a logical, easy to follow manner. You can use the Toulmin method of logic or a simple pattern such as chronological order, most general to most detailed example, earliest to most recent example, etc.
  • Proofread the argument. Too many careless grammar mistakes cast doubt on your character as a writer.

Pathos

Pathos, or emotional appeal, appeals to an audience's needs, values, and emotional sensibilities.

Argument emphasizes reason, but used properly there is often a place for emotion as well. Emotional appeals can use sources such as interviews and individual stories to paint a more legitimate and moving picture of reality or illuminate the truth. For example, telling the story of a single child who has been abused may make for a more persuasive argument than simply the number of children abused each year because it would give a human face to the numbers.

Only use an emotional appeal if it truly supports the claim you are making, not as a way to distract from the real issues of debate. An argument should never use emotion to misrepresent the topic or frighten people.

Aristotle’s "modes for persuasion" – otherwise known as rhetorical appeals – are known by the names of ethos, pathos, and logos. They are means of persuading others to believe a particular point of view. They are often used in speech writing and advertising to sway the audience.

Meaning of Ethos, Pathos and Logos

Aristotle used these three terms to explain how rhetoric works:

"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 [ethos]; the second on putting the audience into a certain frame of mind [pathos]; the third on the proof, or apparent proof, provided by the words of the speech itself [logos]. Persuasion is achieved by the speaker’s personal character when the speech is so spoken as to make us think him credible."

Ethos (sometimes referred to as an appeal to ethics), then, is used as a means of convincing an audience via the authority or credibility of the persuader, be it a notable or experienced figure in the field or even a popular celebrity.

Pathos (appeal to emotion) is a way of convincing an audience of an argument by creating an emotional response to an impassioned plea or a convincing story.

Logos (appeal to logic) is a way of persuading an audience with reason, using facts and figures.

Examples of Ethos, Pathos and Logos

Here are some examples of using ethos, pathos, and logos to persuade.

Ethos

  • "As a doctor, I am qualified to tell you that this course of treatment will likely generate the best results."
  • "My three decades of experience in public service, my tireless commitment to the people of this community, and my willingness to reach across the aisle and cooperate with the opposition, make me the ideal candidate for your mayor."
  • "The veterinarian says that a German Shepherd will be the perfect match for our active lifestyle."
  • "If my years as a Marine taught me anything, it’s that caution is the best policy in this sort of situation."
  • "You know me – I’ve taught Sunday School at your church for years, babysat your children, and served as a playground director for many summers – so you know I can run your preschool."
  • "Our expertise in roofing contracting is evidenced not only by our 50 years in the business and our staff of qualified technicians, but in the decades of satisfied customers who have come to expect nothing but the best."
  • "He is a forensics and ballistics expert for the federal government – if anyone’s qualified to determine the murder weapon, it’s him."
  • "Based on the dozens of archaeological expeditions I’ve made all over the world, I am confident that those potsherds are Mesopotamian in origin."
  • "If my age doesn’t convince you that I know what I'm talking about, at least consider that I am your grandfather and I only want the best for you."
  • "Doctors all over the world recommend this type of treatment."
  • "If you’re still unsure, please consider that my advanced degree and field work speak for themselves."

Pathos

  • "If we don’t move soon, we’re all going to die! Can’t you see how dangerous it would be to stay?"
  • "I’m not just invested in this community – I love every building, every business, every hard-working member of this town."
  • "There’s no price that can be placed on peace of mind. Our advanced security systems will protect the well-being of your family so that you can sleep soundly at night."
  • "Where would we be without this tradition? Ever since our forefathers landed at Plymouth Rock, we’ve celebrated Thanksgiving without fail, making more than cherished recipes. We’ve made memories."
  • "They’ve worked against everything we’ve worked so hard to build, and they don’t care who gets hurt in the process. Make no mistake, they’re the enemy, and they won’t stop until we’re all destroyed."
  • "Don’t be the last person on the block to have their lawn treated – you don’t want to be the laughing stock of your community!"
  • "You should consider another route if you leave later. I heard that that street is far more dangerous and ominous at night than during the daytime."
  • "You’ll make the right decision because you have something that not many people do: you have heart."
  • "After years of this type of disrespect from your boss, countless hours wasted, birthdays missed… it’s time that you took a stand."
  • "Better men than us have fought and died to preserve this great nation. Now is our turn to return the favor. For God and country, gentlemen!"
  • "You will never be satisfied in life if you don’t seize this opportunity. Do you want to live the rest of your years yearning to know what would have happened if you just jumped when you had the chance?"

Logos

  • "The data is perfectly clear: this investment has consistently turned a profit year-over-year, even in spite of market declines in other areas."
  • "Ladies and gentlemen of the jury: we have not only the fingerprints, the lack of an alibi, a clear motive, and an expressed desire to commit the robbery… We also have video of the suspect breaking in. The case could not be more open and shut."
  • "It’s a matter of common sense that people deserve to be treated equally. The Constitution calls it ‘self-evident.’ Why, then, should I have been denied a seat because of my disability?"
  • "More than one hundred peer-reviewed studies have been conducted over the past decade, and none of them suggests that this is an effective treatment for hair loss."
  • "History has shown time and again that absolute power corrupts absolutely."
  • "Private demand for the product has tapered off for the past three years, and this year’s sales figures are at an all-time low. It’s time to research other options."
  • "The algorithms have been run in a thousand different ways, and the math continues to check out."
  • "You won't find any deer along this road. In 25 years of driving the same route, I haven’t seen a single one."
  • "He has a track record of success with this company, culminating in some of our most acclaimed architecture to date and earning us Firm of the Year nine times in a row."
  • "Research compiled by analysts from NASA, as well as organizations from five other nations with space programs, suggests that a moon colony is viable with international support."

Understanding the different aspects of rhetoric will make you more aware of what goes into creating a persuasive argument. The examples above should also help you construct your own arguments or appeals.
