Persuasive and Argumentative Writing

Much important writing aims to persuade — a proposal, a cover letter, an opinion piece, a recommendation. Persuasion in writing is different from in speech: the reader can pause, reread, and pick holes at leisure. That makes a clear, honest, well-structured written argument all the more powerful. This lesson covers how to build one.

Claim, evidence, reasoning

A persuasive piece rests on a clear claim (what you want the reader to accept), supported by evidence (facts, examples, data), connected by reasoning that shows why the evidence supports the claim. Readers are persuaded not by assertion but by the visible logic linking your evidence to your point.

Ethos, pathos, logos

Over two thousand years ago, Aristotle identified three appeals, which apply directly to writing: ethos (credibility — why you're worth believing), logos (logic — the strength of your reasoning and evidence), and pathos (emotion — connecting to what the reader cares about). Strong persuasive writing weaves all three: it is credible, logical, and humanly resonant.

Address the counterargument

Counter-intuitively, acknowledging the strongest counterargument makes you more persuasive, not less. It shows fairness (boosting ethos), pre-empts the reader's objection, and lets you answer it. A concession ('critics rightly note X; however...') disarms resistance. Ignoring the obvious objection makes readers distrust you.

A proposal argues for a four-day work week. It states the claim, gives evidence (studies, a pilot's results), reasons through why the evidence applies here (logos), notes the author's relevant experience (ethos), connects to what leaders care about — retention and morale (pathos), and squarely addresses the strongest objection ('won't output drop?') with data. The argument persuades because it is complete, honest, and structured — not because it shouts.

Persuasion can slide into manipulation — using emotional appeals to bypass reasoning, hiding weak evidence, or misrepresenting the other side. This may work briefly but destroys credibility when exposed, and it is ethically wrong. Honest persuasion respects the reader's judgment: it gives them real reasons, fairly presented, and lets them decide. That is the only kind worth learning.

A celebrated example of persuasive concision is Abraham Lincoln's Gettysburg Address, delivered in November 1863. In roughly 272 words and about two minutes, Lincoln reframed the meaning of a brutal civil war around the founding ideals of liberty and equality and the endurance of democratic government. Its power lies in the very principles of this lesson: it is extraordinarily concise (no wasted word), it carries deep ethos (spoken with solemn authority on a battlefield of the dead), it appeals to shared values and emotion (pathos), and it makes a tight logical case that the living must complete the work the fallen began (logos). That so short a text is remembered when longer speeches that day are forgotten underscores a durable truth: persuasive writing is not about length or ornament but about clarity, structure, and honest appeal to a reader's reason and values. Brevity, marshaled well, can be the most persuasive force of all.

• "Persuasion is mostly about emotion." It needs credibility and logic too; all three appeals matter.
• "Ignore counterarguments so they don't spread." Addressing them fairly makes you more persuasive.
• "Longer arguments are stronger." Concision, as at Gettysburg, often persuades most.
• "Any technique that works is fair." Manipulation destroys credibility and is unethical.

Take something you want to argue in writing. Write the single strongest objection to it, then draft a fair concession-and-response. Notice how addressing it strengthens your case.

Think Like a Maester: Persuade with honest reasons fairly presented — the argument that faces its strongest objection is the one readers trust.

1. What three elements form the core of a written argument?
2. What do ethos, pathos, and logos mean?
3. Why does addressing a counterargument increase persuasiveness?
4. How does honest persuasion differ from manipulation?
5. Why is the Gettysburg Address a model of persuasive writing?

Persuasive writing builds a clear claim on evidence and reasoning, and weaves Aristotle's three appeals: ethos (credibility), logos (logic), and pathos (emotion). Honestly addressing the strongest counterargument makes you more persuasive, not less. Manipulation may work briefly but destroys trust. Lincoln's 272-word Gettysburg Address shows that concise, structured, honest appeal to reason and shared values persuades more powerfully than length or ornament ever could.
