Difficulty: Introductory to Intermediate | Prerequisites: Persuasive Thesis Statements and Rhetorical Situation Analysis (CM 220 Unit 4, Parts I and II).
Aristotle identified three modes of persuasion: ethos (credibility), pathos (emotion) and logos (logic). In CM 220, you are expected to use all three in your argument essay, and to show you understand how each one works and where each is most effective. Equally important is knowing what to avoid: logical fallacies undermine logos, and this unit asks you to identify a specific fallacy and explain how you will steer clear of it. This is the persuasion toolkit that turns a thesis and a rhetorical situation into an actual essay.
Ethos builds trust through your credentials and partnerships. Pathos motivates through vivid, emotionally resonant examples. Logos persuades through data, evidence and sound reasoning. A strong argument uses all three, and avoids logical fallacies (such as hasty generalisation) that would undercut the logos appeal.
Ethos
The appeal to credibility and character. You persuade by showing the audience you are trustworthy, knowledgeable and fair-minded. Think of it as: "Why should you listen to me?" Personal experience, professional credentials and partnerships with respected organisations all build ethos.
Pathos
The appeal to emotion. You persuade by evoking feelings (compassion, urgency, anger, hope) that motivate the audience to care and act. In simple terms, pathos makes the argument feel personal. A story about a family struggling in winter cold does more than a statistic alone.
Logos
The appeal to logic and evidence. You persuade by presenting data, statistics, research findings and sound reasoning. Think of it as the "prove it" appeal. Logos is where your sources, numbers and cause-and-effect arguments live.
Logical fallacy
An error in reasoning that weakens an argument. Fallacies can be intentional (manipulative) or accidental (sloppy thinking). In CM 220, you must identify a fallacy relevant to your topic and explain how you will avoid it.
Hasty generalisation
Drawing a broad conclusion from too few examples or insufficient evidence. For example, concluding that all homeless people are lazy based on one or two observations. In simple terms, it is jumping to a conclusion without enough proof.
Ad hominem
Attacking the person making the argument rather than the argument itself. For example, dismissing a housing advocate's proposal because of their political affiliation rather than engaging with the evidence. Think of it as: going after the messenger instead of the message.
Rival hypothesis (rival thesis)
An alternative explanation for the problem that your audience may hold. You must acknowledge it and show why your explanation is stronger. For example, the rival hypothesis that homelessness is caused by personal choices (substance abuse, lack of education) rather than systemic factors. Addressing it head-on strengthens your argument rather than leaving it as an unspoken objection.
Ethos answers the question: "Why should the audience trust you on this topic?"
Sources of ethos in a CM 220 essay:
Personal experience: volunteering with homeless populations, running a non-profit, witnessing conditions first-hand
Partnerships: working alongside housing advocates, business leaders and city officials signals that your perspective is informed and collaborative
Fairness: acknowledging the other side's concerns (taxpayers worried about increased taxes) shows you are not dismissing legitimate objections
Ethos is not just about you. Citing credible sources (government reports, established organisations) transfers their credibility to your argument
Addressing the rival hypothesis is an ethos move. When you acknowledge that some people believe homelessness results from personal choices and then counter with systemic evidence, you show intellectual honesty
Pathos makes the audience feel the problem, not just understand it
Effective pathos techniques for this topic:
Concrete, specific images: "A family with children struggling to find food and shelter in the winter" is pathos. "Homelessness is sad" is not
Veteran stories: meeting veterans with PTSD living on the street connects the issue to a group the audience already respects and sympathises with
Calls to action framed as small, achievable acts of kindness rather than overwhelming systemic demands
Pathos works best when it is specific and restrained. One well-told example is more persuasive than a list of tragedies
Pathos without logos is manipulation. Always pair emotional appeals with evidence
Logos is the backbone of the argument. Without it, ethos and pathos are just feelings and reputation
Building logos for this topic:
Local data: the Charlotte-Mecklenburg Housing and Homeless Fact Sheet (2023) reports 2,792 evictions per month. That number does the work
Cause-and-effect reasoning: eviction filings, even when resolved, create a barrier to future housing. This connects the data to the argument
Financial burden: increased law enforcement costs from homelessness give fiscally minded stakeholders a reason to support the solution
A source must be cited. In CM 220, you need at least one named, referenced source in the appeals section
Logos is where fallacies live. Every claim in your logos section should be checked against common fallacies
The assignment asks you to name a specific fallacy and explain your avoidance strategy
Hasty generalisation is the most relevant fallacy for homelessness arguments:
The fallacy: "Homeless people are lazy" (generalising from stereotypes or a few cases)
The avoidance: present the multiple pathways to homelessness (eviction, mental illness, job loss, domestic violence) so the audience sees the complexity
Other fallacies to watch for:
Ad hominem: attacking opponents of your solution personally rather than engaging with their arguments
False dilemma: presenting only two options ("Either we tax businesses or we do nothing") when other funding mechanisms exist
Appeal to pity: relying solely on emotional stories without evidence (this is pathos without logos)
The test for any claim: could a reasonable, informed person disagree with how you reached this conclusion? If yes, you need more evidence or a more careful argument
Students often treat the three appeals as separate essay sections ("my ethos paragraph, my pathos paragraph"). In practice, a single paragraph can use all three. The appeals are lenses, not containers
Pathos does not mean being emotional yourself. It means selecting details that produce an emotional response in the reader. The writing itself should stay controlled
Students sometimes confuse logos with "using big words" or sounding academic. Logos is about evidence and valid reasoning, not vocabulary
Naming a fallacy is not the same as avoiding it. The assignment asks you to explain your strategy for avoidance, which means showing what you will do differently (present multiple pathways, cite diverse evidence)
Expect to be given a passage and asked to identify which appeal (ethos, pathos, logos) it uses. Practise labelling examples
You may be asked to explain how you would use a specific appeal for a given audience. The answer depends on what that audience values
Logical fallacies are frequently tested. Be able to define at least four (hasty generalisation, ad hominem, false dilemma, appeal to pity) and give an example of each
The rival hypothesis question is common: "What is an opposing explanation, and how do you counter it?" Have a prepared answer that names the rival view and offers specific evidence against it
Fill in the blank: The three rhetorical appeals are ______, ______ and ______. (ethos, pathos, logos)
True or false: Citing a government housing report is primarily an example of pathos. (False, it is logos)
Fill in the blank: A ______ ______ is a broad conclusion drawn from too few examples. (hasty generalisation)
True or false: Acknowledging a rival hypothesis weakens your argument. (False, it strengthens your ethos and logos by showing intellectual honesty)
Fill in the blank: An ______ ______ fallacy attacks the person making the argument rather than the argument itself. (ad hominem)
Q: A writer states they volunteered at a homeless shelter for three years. Which appeal does this primarily establish, and why?
A: Ethos. It establishes the writer's credibility through direct, sustained experience with the issue. The audience is more likely to trust someone who has worked closely with the problem.
Q: Explain why the statement "All homeless people made bad choices" is a logical fallacy. Name the fallacy.
A: This is a hasty generalisation. It draws a sweeping conclusion about an entire population based on limited evidence or stereotypes. In reality, homelessness has many causes, including eviction, mental illness, job loss and domestic violence.
Q: A student writes an argument relying entirely on a story about one homeless veteran. What appeal is overused, and what is missing?
A: Pathos is overused. The argument is missing logos (data, statistics, research evidence). One story, however moving, cannot support a policy recommendation on its own.
Q: How does addressing a rival hypothesis strengthen your argument?
A: It shows intellectual honesty (ethos) and demonstrates that your position holds up even when the strongest objection is considered (logos). An argument that ignores the obvious counterpoint looks either uninformed or evasive.
Q: Identify the fallacy: "We should ignore the housing advocate's proposal because she has never experienced homelessness herself."
A: Ad hominem. The statement attacks the advocate's personal experience rather than engaging with the evidence and reasoning in her proposal.
The three appeals connect back to the rhetorical situation (Part II): your audience analysis tells you which appeal to emphasise. A city council weighing budgets responds to logos; a community group responds to pathos and ethos. The thesis (Part I) provides the claim that all three appeals serve. In Unit 5, you will build these appeals into full body paragraphs with cited evidence, so practising the connection between appeals and sources here saves time later.
