This lesson examines how ethos, pathos, and logos work together to create a balanced argument.
Imagine you are trying to convince your parents to let you stay out late. Do you show them your straight-A report card, tell them how lonely you'll feel if you miss the party, or explain the logical safety of the neighborhood? The most persuasive people don't just pick one—they use all three.
In rhetoric, ethos (credibility), pathos (emotion), and logos (logic) rarely work in isolation. Think of them like the ingredients in a recipe. If you have only salt, the dish is ruined; if you have the right balance, the meal is a masterpiece. This interaction is called the interplay of appeals. When a speaker uses logos to provide facts, they often use ethos to prove those facts come from a reliable source. Meanwhile, pathos ensures the audience actually cares about those facts. A balanced argument typically follows a ratio where no single appeal overwhelms the others, creating a 'rhetorical harmony' that is difficult to ignore.
Quick Check
Why is it often ineffective to rely solely on Pathos (emotion) in a serious argument?
Answer
Without Logos or Ethos, an audience may feel manipulated or believe the speaker lacks a factual basis for their claims.
Read this sentence: 'As a cardiologist with 20 years of experience (Ethos), I can tell you that clinical trials show a reduction in heart disease (Logos) for those who walk daily, which means you can spend more healthy years with your grandchildren (Pathos).'
1. Ethos: Established by the '20 years of experience.' 2. Logos: Provided by the ' reduction' statistic. 3. Pathos: Created by the emotional image of 'grandchildren.'
All three work together to make the advice feel both authoritative and urgent.
Sometimes, one appeal can actually weaken another. This is called rhetorical dissonance. For example, if a speaker uses extreme pathos (like shouting or crying) while trying to establish ethos as a calm, objective expert, the audience might stop trusting them. Conversely, a strong logos-based argument can be strengthened by ethos. If a Nobel Prize-winning physicist explains a complex formula, you are more likely to accept the logic () because of their status (). In Grade 9 rhetoric, your goal is to see how these appeals 'stack' on top of one another to build a sturdier case.
Consider a commercial for a new security system: 'Our system uses military-grade encryption (Logos). Don't let your family become another tragic statistic in a cold, dark world (Pathos). Trust us because we are the biggest company in the world (Ethos).'
Analysis: 1. The Pathos is very heavy ('tragic statistic,' 'cold, dark world'), which might feel like 'scare tactics.' 2. This heavy Pathos might actually make the Ethos feel less 'trustworthy' and more like a high-pressure sales pitch. 3. The Logos is present but vague, leaving the audience with more fear than information.
Quick Check
How can a speaker's Ethos (credibility) affect how the audience perceives their Logos (logic)?
Answer
High Ethos makes the audience more likely to accept logical claims as true without demanding excessive proof.
To evaluate a text, look for the dominant appeal. If a text is Pathos, it is likely an emotional plea. If it is Logos, it might be a technical manual. The most effective persuasive writing—like famous speeches or high-end editorials—aims for a 'Golden Ratio' where the logic is supported by the speaker's character and fueled by the audience's values. When comparing two texts, ask: 'Which one provides enough evidence (Logos) to satisfy my brain, while giving me enough reason (Pathos) to care, and enough trust (Ethos) to believe?'
Text A: 'The school needs a new gym. It's been 50 years. Our athletes are sad.' Text B: 'According to the 2023 Safety Audit (Ethos), our gym floor has a higher risk of causing injury (Logos). Investing in our students' safety today ensures a legacy of excellence for future generations (Pathos).'
1. Text A relies almost entirely on Pathos but lacks specific Logos or Ethos. 2. Text B uses Ethos (the Audit) to introduce a logical risk factor (), then concludes with a Pathos-driven 'legacy' statement. 3. Conclusion: Text B is more effective because the appeals support each other.
If a speaker uses a lot of statistics () but has a reputation for lying (), what is the likely result?
A single sentence can contain Ethos, Pathos, and Logos at the same time.

Practice Activity
Find a commercial on YouTube and count how many times they use a 'fact' (Logos) versus a 'feeling' (Pathos). Does the spokesperson seem like an expert (Ethos)?
