After the personal essay, the argumentative essay may be the most popular essay type for professors to assign. As a result, tons of argumentative essays are produced every semester. Many of them could be much better if students approached this essay type with a correct conception of the purpose of writing an argument.
Your purpose is not to boil a complicated question down to a blunt and obvious answer. Instead, your purpose in writing an argumentative essay should be to seriously consider and address the strongest possible opposition to the point of view you wish to advocate or to consider and refute an interesting and complicated position. An argumentative essay is really an act of the imagination and research, and the best way to write a compelling piece is to find the most convincing and difficult-to-refute opposition to your arguments.
Unlike a persuasive essay—which attempts to persuade the reader rather than argue with them—the argumentative essay presents a limited number of alternative positions and states a preference for one over the other. However, this does not mean that a writer must always choose between "good" and "bad," "right" and "wrong," or "true" and "false."
In many instances, a writer might argue on behalf of a nuanced point of view that rejects either side of a well-worn argument. For example, a writer might argue that euthanasia is acceptable in some situations, but that the ethical dangers are multiplied by socialized medicine, which risks putting life and death decisions in the hands of the state. Such an argument would be far more compelling and imaginative than an essay that simply argues "for" or "against" euthanasia.
More than other essay types, the argumentative essay gives students the opportunity to imagine another point of view. As a writer, your job is to start by ensuring that the point of view you're opposing is interesting. Picking an interesting opponent makes the game more challenging for the writer, perhaps, but far more rewarding for the reader.
In the euthanasia example, the writer is not merely objecting to the position that euthanasia is good. Instead, the writer is objecting to the complex position that one can simultaneously support euthanasia and socialized medicine without running into major ethical problems. In this case, inventing a difficult opponent sets the stage for a more engaging essay than most. Once you've established a multifaceted opponent, follow the basic pattern of the five paragraph essay type to present supporting statements and defend your position.
The distinction between persuasion and argument is worth pressing because it identifies two entirely different relationships between the writer and the reader. Persuasion positions the reader as a target—someone to be moved from one position to another through the strategic deployment of evidence, emotional appeal, and rhetorical momentum. Argument positions the reader as a partner in a shared inquiry—someone capable of evaluating competing claims, weighing evidence, and arriving at a conclusion through their own reasoning rather than the writer's force of will. The argumentative essay, properly understood, is an act of intellectual respect. It assumes a reader who can handle complexity, who will not be alienated by a qualified conclusion, and who will find a nuanced position more persuasive precisely because it has not been simplified for their convenience. That assumption changes everything about how the essay is constructed—from the choice of opponent to the structure of the concession to the register of the conclusion.
The instruction to find an interesting opponent deserves to be treated as a research directive rather than a rhetorical one, because the most interesting opponents are not invented—they are discovered. The student who sits down to argue against a position they have not seriously investigated will construct a straw man by default, not out of laziness but out of ignorance: they simply do not yet know what the strongest version of the opposing position looks like. The research phase of the argumentative essay is the phase in which the writer locates that strongest version—reads its best advocates, understands its internal logic, identifies the evidence it marshals and the values it prioritizes—and only then decides how to engage it. The opponent that emerges from that process is not a caricature. It is a genuine intellectual position held by thoughtful people for defensible reasons, and the essay that takes it seriously enough to represent it accurately before dismantling it is the essay that demonstrates what argumentative writing, at its best, is actually for: not the defeat of the opposition, but the clarification of what is genuinely at stake when two serious positions meet.
