Relevance in Logical Arguments

Definition of Relevance in Logical Arguments

In the world of logical arguments, ‘relevance’ is a key to checking if the ideas you’re saying are really helpful for what you’re trying to prove or explain. Imagine relevance as a magnet. Just like a magnet only sticks to some metals, relevance means your point or information specifically sticks to the topic you’re dealing with. If you’re having a discussion about space, and you bring up something about the ocean, unless you’re comparing planets to the deep sea, that point may not stick—it’s not relevant.

Moreover, relevance is also like the ingredients in a recipe. If you’re baking a cake, ingredients like flour, eggs, and sugar are relevant because they’re part of the recipe. But if you toss in ketchup, that doesn’t belong—it’s not relevant to your baking. So when you share a point, think to yourself, “Is this like flour for my cake, or is it like ketchup?” If it doesn’t make your ‘cake’ better, it’s probably not what you need.

Types of Relevance in Logical Arguments

While debating or discussing, there are different ways to make sure your points fit the puzzle. People don’t usually break down relevance into strict categories, but we can look at it from different angles, like:

  • Logical Relevance: Just like pieces in a puzzle, it’s about connecting facts and thoughts in a way that makes a clear picture when you put them all together.
  • Topical Relevance: This is about keeping the conversation focused. If you’re talking about a movie, stay on the topic of the movie rather than shifting to your weekend plans.

Even if these angles of relevance seem separate, they actually work together like a team to make sure everything in your argument is helpful and ties back to the main point you are discussing.

Examples of Relevance in Logical Arguments

  • While debating the benefits of fruits and veggies, mentioning that carrots are good for your eyesight is relevant because it’s a fact directly connected to the topic—health benefits of food.
  • In a discussion about internet safety, bringing up strong passwords counts as relevant since it’s a practice that’s directly linked to keeping your information safe online.
  • If a class is discussing pollution, talking about car emissions is relevant because it’s one of the causes of air pollution, showing a direct link to the topic.

Why is Relevance Important?

Relevance helps your argument stay on track, much like a train follows its rails. It’s essential for your train of thought to reach its destination—the point you want to make. When every piece of your argument is relevant, it fits to form a clear picture, convincing others more effectively. Unrelated information is like extra weight that slows the train down, and it might even lead others to believe you’re not sure about your own point.

In everyday situations, like school or talking with friends, staying relevant keeps the conversation meaningful. If you’re discussing a project with your team, focusing on relevant tasks helps you get the job done without wasting time. Relevance isn’t just for formal debates, it’s part of every effective conversation.

Related Topics

Understanding relevance is great, but it’s also connected to other ideas in arguments and discussions:

  • Evidence: The solid facts and information that you use to support your arguments need to be not just true but also relevant to what you’re arguing about.
  • Coherence: This is about making sure your argument makes sense as a whole; relevance of each point to the main argument contributes to its coherence.


To put it all together, relevance is like the glue that keeps all the parts of your argument sticking to the main point. By making sure every piece of information has a clear connection to the topic at hand, your argument will be stronger and more likely to convince others. Next time you’re in a discussion, keep relevance in mind—it’s your secret weapon for building an argument that’s hard to knock down.
