Public Speaking · Ethos, logos & pathos

Join reasoning, credibility, and human significance

Persuasion involves an argument, a trustworthy speaker, and a listener who understands what is at stake.

Lesson 5 of 12 · About 5 minutes

Three complementary questions

Classical rhetoric distinguishes persuasion through the speaker’s character, the audience’s emotional disposition, and the argument itself. The familiar labels are ethos, pathos, and logos. Use them as questions: why should this account be trusted, what reasons support it, and why should the issue matter to these listeners? None supplies a substitute for the others.

Build credibility inside the speech

Represent the evidence accurately, concede a fair limitation, and show that you understand the strongest opposing concern. These choices make your judgment visible. Listing credentials may establish experience, but it cannot rescue an inference that does not follow. A candid “I do not yet know” can preserve trust when followed by a clear account of what would settle the question.

Make significance concrete without distorting it

Show how a decision affects a person, a responsibility, or a shared institution. A human example can help listeners understand the stakes, provided its status and limits are clear. Avoid implying that disagreement proves indifference or bad character. Strong emotion should arise from an accurate account of something consequential.

From an intention to a usable choice

First attempt

Anyone who cares about our community must support this proposal.

Revision

This proposal aims to make meetings accessible to members working evenings. The benefit is real, but so is the scheduling cost. I favor a four-week trial because it would let us test both before making a permanent commitment.

The speaker identifies the human stake, acknowledges a competing concern, and supplies a reason for a bounded recommendation.

Try it aloud

A focused drill

Mark one sentence in your outline that supplies a reason, one that establishes the stakes, and one that demonstrates fair judgment. Revise any sentence that claims moral superiority instead of supporting the proposal.

Listen for this: Could someone reject your proposal while recognizing that you described their concern fairly?
