Paper 4 asks you to compare two articles on cryonics (one anti, one pro) and decide which makes the stronger argument. The task is rhetorical analysis: evaluating each article's use of logos, ethos, and pathos, identifying logical fallacies, and judging the quality of evidence. Your thesis must clearly state which article argues more effectively and why.
Logos
Appeal to logic and reasoning. Includes the use of facts, statistics, evidence, and structured reasoning to support a claim.
Ethos
Appeal to credibility or authority. Established through an author's qualifications, use of reputable sources, professional tone, and fair treatment of opposing views.
Pathos
Appeal to emotion. Uses emotionally charged language, vivid imagery, or personal stories to influence the audience's feelings.
Counterargument
An opposing viewpoint that an author acknowledges and responds to within their own argument. Addressing counterarguments strengthens credibility.
Logical fallacy
An error in reasoning that weakens an argument. Can be formal (structural flaw in logic) or informal (flaw in content, relevance, or sufficiency of evidence).
Thesis statement
A single sentence (or occasionally two) that states the writer's central claim. For Paper 4, it must declare which article argues more effectively and preview the reasoning.
Article A (anti-cryonics): Michael Hendricks, "The False Science of Cryonics"
Presents factual information on the downsides of cryonics
Acknowledges a counterargument
Relies heavily on anecdotes and contains bias
Article B (pro-cryonics): Cain, "Why Cryonics Is a Good Option"
Draws on multiple sources and research studies
Less reliant on anecdotal evidence
Potentially assumes cryonics is positive without fully proving it (circular reasoning risk)
The revised thesis from the outline reads: while Hendricks attempts to appeal to the reader's logos through factual evidence, Cain's article is the stronger argument because it utilises multiple resources and does not rely on anecdotes.
Key elements of a strong thesis for this paper:
Names both articles and authors
States which argument is stronger
Previews the reasoning (e.g. evidence quality, source diversity, fallacy burden)
Three organisational plans were considered in the outline:
Plan 1 (article-by-article): cover Article A's strengths then weaknesses, then Article B's weaknesses then strengths. Simple but risks becoming two separate summaries rather than a comparison.
Plan 2 (appeal-by-appeal): organise by logos, ethos, and pathos. Under each appeal, compare both articles and declare which is stronger. This is the recommended structure from the outline.
Plan 3 (strengths vs. weaknesses): group all strengths together, then all weaknesses. Clean, but harder to sustain a comparative argument throughout.
The outline settles on a version of Plan 2, structured as:
Introduction with cryonics background and thesis
Logos section (both articles compared)
Ethos section (both articles compared)
Pathos and fallacies section (both articles compared)
Conclusion
Neither article uses statistics or hard numerical data. Both rely on reasoning and explanation of facts.
Key distinction: the pro-cryonics article (Cain) draws on multiple sources, which strengthens the logical foundation even without numbers. Hendricks relies more on reasoning from fewer sources.
When evaluating logos, consider:
Quantity and variety of evidence cited
Whether claims are supported or merely asserted
Whether the reasoning follows logically from the evidence presented
Questions to ask of each article:
What are the author's credentials or affiliations?
Does the author use reputable, verifiable sources?
Does the author treat opposing views fairly or dismiss them?
Is the tone measured and professional, or dismissive and biased?
Questions to ask of each article:
Does the author use emotionally loaded language?
Are anecdotes used in place of evidence, or alongside it?
Does emotional appeal strengthen or substitute for logical reasoning?
⚠️ You must define rhetorical terms (logos, ethos, pathos, fallacy) within the essay itself, not just use them. The assignment instructions say so explicitly.
⚠️ Counterarguments matter. Evaluate whether each author acknowledges and addresses opposing views, and whether any obvious counterarguments are left out.
⚠️ The thesis must take a clear position on which article is stronger. A thesis that says "both have strengths and weaknesses" without choosing a side will not meet the assignment brief.
⚠️ Evidence quality is a major evaluation axis. An article that cites multiple research studies carries more weight than one that relies on anecdotes, all else being equal.
Q: What is the key difference between logos and ethos?
A: Logos is the appeal to logic and reasoning (facts, data, structured arguments), while ethos is the appeal to credibility and trustworthiness (author qualifications, reputable sources, fair treatment of opposition).
Q: Why does the outline argue that Cain's article is stronger than Hendricks's?
A: Cain's article utilises multiple sources and research studies, whereas Hendricks relies heavily on anecdotes and contains bias, weakening the logical and ethical foundation of his argument.
Q: Which essay structure does the outline recommend, and why?
A: The appeal-by-appeal structure (Plan 2), organised around logos, ethos, and pathos. This keeps the comparison active throughout the essay rather than separating the articles into isolated summaries.
Q: Why is it important to define terms like logos and pathos within the essay?
A: The assignment instructions require it. Defining terms shows the reader you understand the analytical framework and ensures your argument is accessible.
