Understanding the Incomplete Possession Fallacy: A Key Rhetorical Device in Classical Argumentation

When it comes to classical argumentation, the use of fallacies can significantly influence the strength and persuasion of an argument. One such fallacy that often flies under the radar is the incomplete possession fallacy. This article will explore what the incomplete possession fallacy is, how it operates, and its implications in argumentative discourse.

What is the Incomplete Possession Fallacy?

The incomplete possession fallacy occurs when a speaker claims that an entity possesses certain qualities or characteristics based on incomplete evidence. In essence, it's a logical misstep where the argument is founded on a partial understanding of the subject in question. This fallacy can lead an audience to draw incorrect conclusions, often strengthening the speaker's position despite the lack of comprehensive evidence.

For example, consider an argument that states, "Because Jane is skilled at programming, she must be able to create any software application." This statement overlooks the complexities of software development, suggesting that one skill translates to complete competence in an entirely different arena.

How the Incomplete Possession Fallacy Works in Argumentation

1. Overgeneralization

The incomplete possession fallacy thrives on overgeneralization, where a conclusion is drawn from insufficient examples. In rhetoric, this can mislead audiences into believing that a broader application exists based solely on limited evidence.

• Example: “All politicians are lying, because I heard two politicians lie during a debate.”

2. Misleading Comparisons

Another way this fallacy surfaces is through misleading comparisons, equating two unlike entities based on a shared characteristic that does not necessarily apply on a broader scale.

• Example: “Cars are built to last like my grandfather's old truck; therefore, all new cars should last at least 50 years.”

These faulty comparisons can distort a listener's perception, leading them to accept flawed reasoning as valid.

Real-World Applications

The incomplete possession fallacy can be pervasive in various domains. In advertising, for instance, companies might claim that their product is superior based solely on limited success stories, ignoring the plethora of alternatives available.

In political discourse, speakers may invoke the incomplete possession fallacy to sway public opinion. For instance, a candidate may suggest that because they have successfully implemented a program at a local level, it will work effectively on a national scale, without considering systemic differences.

Avoiding the Incomplete Possession Fallacy

Understanding the incomplete possession fallacy is crucial for both speakers and listeners. Here are some strategies to avoid falling victim to this fallacy in argumentation:

1. Demand Comprehensive Evidence: When evaluating an argument, always seek comprehensive evidence. Are the claims based on sufficient data? Are there counterexamples or viewpoints presented?

2. Analyze Assumptions: Identify the assumptions underlying the argument. Are they fair and well-supported?

3. Look for Logical Consistency: Examine if the conclusion logically follows from the premises. If there’s a gap, the argument may be susceptible to the incomplete possession fallacy.

4. Engage in Critical Thinking: Encourage critical thinking in discussions. Question the logic and ensure that claims match the complexity of the situation.

Conclusion

The incomplete possession fallacy is a powerful rhetorical device that, when recognized and understood, can greatly enhance the clarity of argumentation. By being aware of how this fallacy operates, individuals can engage in more nuanced discussions that ultimately lead to a deeper understanding of complex issues.
