Explain the principles for making rational argument and judgment in literature

What Is an Argument?

An argument in logic consists of premises (the reasons or evidence) and a conclusion (the claim being supported). The premises are presented to convince the audience that the conclusion is true. For example:

• Premise 1: All humans are mortal.
• Premise 2: Sokrates is human.
• Conclusion: Therefore, Sokrates is mortal.

Types of Arguments

Deductive argument moves from general principles to a specific conclusion. If the premises are true and the reasoning is valid, the conclusion must be true. For instance, if all novels are literary works and Things Fall Apart is a novel, then Things Fall Apart is a literary work.

Inductive argument moves from specific observations to a general conclusion. It provides probable but not certain support. For example, if three characters in a novel betray their friends, one might conclude that betrayal is a recurring theme in that novel.

Rational Judgment

Rational judgment means forming opinions or making evaluations based on evidence, logic, and objective analysis rather than on personal preferences, emotions, or biases. In literature, this involves assessing characters' actions, themes, or the author's message using sound reasoning.

When constructing or evaluating an argument, six key principles should guide your reasoning:

1. Logic

An argument is logical when the conclusion follows from the premises without contradiction. The reasoning must be valid—if the premises are true, the conclusion must be true. For example, arguing that "because it rained yesterday, the ground is wet" follows logically, whereas claiming "it rained yesterday, therefore the ground will definitely be wet tomorrow" contains a logical flaw.

2. Evidence

Use relevant and reliable evidence from credible sources. In literature, evidence comes from the text itself—quotes, character actions, plot events, or authorial choices. Avoid relying on unsupported claims or emotional appeals.

3. Clarity

Communicate your ideas clearly so your audience understands your reasoning. Ambiguous language or confusing structure weakens an argument. State your premises explicitly and connect them logically to your conclusion.

4. Objectivity

Remain unbiased and evaluate evidence impartially. Do not let personal feelings, cultural biases, or emotional reactions cloud your judgment. Consider all perspectives fairly before reaching a conclusion.

5. Consideration of Counterarguments

Anticipate that others may disagree with your argument. Acknowledge opposing viewpoints and address them thoughtfully. This strengthens your position by showing you have considered alternative perspectives.

6. Relevance

Focus only on information that directly supports your conclusion. Irrelevant premises weaken an argument. For instance, claiming "she should win the case because she is wealthy" introduces irrelevant information that does not logically support the conclusion.

When assessing an argument—whether your own, someone else's, or a character's in a literary work—ask two key questions:

1. Does the evidence logically support the argument? Check whether the premises truly lead to the conclusion. A gap between evidence and conclusion indicates weak reasoning.

2. Are the premises true or believable? Examine whether the foundational claims are accurate. False or questionable premises undermine the entire argument.

Worked Example

Consider the following scenario from the textbook:

Mr Chanja is charged with murder. Bloodstains were found at the scene and DNA testing confirmed they belonged to Mr Chanja. The forensic technician testified in court. Judge Makwima concluded that Mr Chanja was guilty.

Evaluating Judge Makwima's argument:

• Premise 1: Bloodstains found at the scene contained Mr Chanja's DNA.
• Premise 2: The forensic technician provided credible expert testimony.
• Conclusion: Mr Chanja is guilty of murder.

This argument follows logical reasoning, uses relevant evidence, and remains objective. However, one might counter that DNA evidence proves Mr Chanja was present but does not prove he committed the act—he could have been present innocently. This demonstrates how counterarguments refine rational judgment.

To refute means to present an opposing argument that challenges or defeats a claim. You can refute an argument by:

• Questioning the truth of the premises
• Showing the premises are irrelevant to the conclusion
• Demonstrating a logical fallacy
• Providing contradictory evidence

Example:

• Original argument: "Teachers are important in society because they breed all other professions."
• Refutation: This argument is flawed because teachers do not literally "breed" professionals. They educate and train people, but many professions exist independently of formal teaching. The premise uses imprecise language and overgeneralizes the role of teachers.

When analyzing literature, use these principles to evaluate characters' decisions or the author's arguments:

• Examine whether characters' actions are supported by believable motivations (evidence)
• Judge whether the author's themes are logically developed (logic)
• Consider alternative interpretations of the text (counterarguments)
• Assess whether the author's conclusions follow from the events and details presented (relevance)

In everyday life in Tanzania, rational argument and judgment help you make better decisions. For example, when buying a phone at the Mwanga jiko market in Dar es Salaam, a rational buyer gathers evidence about different brands, compares prices and features objectively, and considers counterarguments from sellers before deciding—rather than choosing simply because a friend recommended it emotionally. This same logical approach applies to evaluating business opportunities, discussing social issues with peers, or assessing news information in WhatsApp groups.
