Mastering Argumentation: 5 Essential Tools for Philosophers
Written on
In various discussions—whether with colleagues, friends, or family—there are moments when our beliefs on topics like ethics, politics, or religion are questioned. As philosophers, we often feel confident in our stance. Yet, persuading others can be challenging, leading us to wonder if we are missing something in our approach.
Indeed, many of us lack familiarity with the effective strategies philosophers employ to structure their arguments and secure victories in debates. Fortunately, these techniques are accessible and can be mastered through practice and training. Thankfully, resources like Plato’s Gymnasium are available to guide us. Here are five key argumentative tools that professional philosophers regularly utilize to engage and outmaneuver their opponents.
The Syllogism
One of the oldest tools in philosophical argumentation is the syllogism, which continues to underpin contemporary discussions. A syllogism involves drawing conclusions from premises using a logical structure, similar to mathematical reasoning. For instance:
- Abortion is equivalent to murder.
- Susie had an abortion.
- Therefore, Susie is a murderer.
Aristotle's view on syllogisms is that if the premises are true, the conclusion must also hold true. This logical framework is commonly used in philosophical debates, particularly on contentious topics like abortion. Thus, recognizing, analyzing, and utilizing syllogisms is crucial for effective discourse.
Validity
Assessing the validity of an argument involves scrutinizing its structure rather than its content. Take this syllogism as an example:
- All abortion providers have Watergate Salad for brains.
- Jim is an abortion provider.
- Therefore, Jim has Watergate Salad for brains.
While the premises lead to a logical conclusion, the absurdity of the premises does not undermine the argument's validity. Conversely, if the conclusion does not logically follow from the premises, the argument is deemed invalid, even if the conclusion itself is true:
- All abortion providers have Watergate Salad for brains.
- Jim has Watergate Salad for brains.
- Therefore, Jim is an abortion provider.
In this case, the conclusion does not logically follow, rendering the argument invalid.
Soundness
Once we determine an argument's validity, we must evaluate the truth of its premises. Consider this syllogism:
- Abortion is equivalent to murder.
- Susie had an abortion.
- Therefore, Susie is a murderer.
While the conclusion might logically follow, the premise that equates abortion with murder is highly disputed. Thus, although the argument is valid, it is unsound due to the contentious nature of its premise. A sound argument requires both validity and truth across all assertions.
Formal Fallacy
A frequent source of invalid reasoning is the formal fallacy known as "affirming the consequent." This occurs when conditional premises lead to ambiguous conclusions. For example:
- If Jim the abortion provider encounters protesters, he will enter through the back.
- Jim entered through the back.
- Therefore, he encountered protesters.
This argument is invalid because the premises do not guarantee the conclusion's truth. If we alter the premise to "If and only if Jim meets protesters, he will take the back entrance," the argument becomes valid. This distinction highlights the importance of precision in our reasoning.
Axioms
Axioms are statements considered true by definition. A classic example is, "All unmarried men are bachelors." While this seems solid, it merely restates the definition without providing substantive content. In our ongoing discussion, an axiom might be, "All murderers kill people," which is true but also prompts deeper questions about personhood and the nature of abortion.
Debates surrounding these axioms can be complex, particularly in contentious topics like abortion, where definitions and assumptions are often challenged. Recognizing and questioning these foundational assumptions can provide a significant advantage in philosophical discussions.
Conclusion
The five tools discussed here are invaluable for challenging common beliefs regarding ethics, politics, culture, and justice. They not only enhance your ability to critique others but also refine your own thinking. Embrace these tools and strive not just to read philosophical works but to embody the philosopher's role in everyday conversations.
