Applied Logic

Definition of Applied Logic

Applied Logic is like the brain’s toolkit for tackling puzzles that real life throws at us. Imagine a friend gives you a jumbled bunch of LEGO pieces and asks you to build something; logic is what helps you figure out how they fit together to make something cool. Applied Logic takes that logic ‘toolkit’ and puts it into action, helping you build clear thought patterns, which is just a fancy way of saying ‘knowing how to think to solve problems.’

Another way to look at Applied Logic is that it’s a map to the treasure hidden in complicated situations. It’s like when you have a box with a secret compartment and you think, “If I press this button, and turn this knob, then the hidden drawer should pop open.” Applied Logic uses if-then statements and other rules of logic to lead you to the ‘treasure’—which could be an answer to a problem or simply understanding something better.

Types of Applied Logic

  • Deductive Logic: Think of it as playing a ‘top-down’ video game—you start with the big picture and zoom into the details. It’s like saying, “All smartphones can access the internet. My phone is a smartphone. Therefore, my phone can access the internet.”
  • Inductive Logic: This one’s like building a pyramid from the ground up. You gather specific bits, like bricks, and stack them to make a bigger picture. An example would be, “Jenny’s hamster loves to run on a wheel, and so do her three friends’ hamsters. It seems like all hamsters must love running on wheels.”
  • Abductive Logic: This is when you play detective and look at the evidence to figure out the most sensible answer. If you find your muddy shoes missing after your little sister has been playing outside, you might guess she’s used them.

Examples of Applied Logic

  • Doctors use applied logic to work out what might be wrong with a patient by looking at their symptoms. It’s a way of saying, “If these symptoms usually mean illness X, and you have these symptoms, you might have illness X.”
  • Computer scientists rely on applied logic to devise algorithms that make things like websites and apps work seamlessly. It’s similar to setting up a series of dominoes to fall in a specific pattern.
  • In court, lawyers use applied logic to put together pieces of evidence into a story that shows whether someone did or didn’t do something. They might argue, “If the suspect was seen at the scene, and nobody else was there, then the suspect may be guilty.”
  • You also use applied logic when you’re figuring out stuff like the quickest path to take to school when the usual road is clogged with traffic. It’s a bit like solving a maze by thinking ahead about which turns to take.

Why is it Important?

Applied Logic is the secret ingredient that helps turn a jumble of ideas into clear thoughts and good decisions. When we look at the world, it can sometimes feel like a giant puzzle with too many pieces. Applied logic helps us sort through them and put it all together. It lets us go beyond guessing and making random choices by giving us a way to use facts and evidence for better results. This approach is crucial not just for personal decisions but also for complex tasks like programming a computer, figuring out medical diagnoses, or developing strategies in a business.

If we didn’t have applied logic, we might decide things based only on our feelings, which can sometimes steer us wrong. Logic acts like a fair referee in a sports game—it ensures that our thoughts and arguments follow the same ‘fair play’ rules so we can find out what’s really likely to be true. For everyday people, this is vital. It’s the difference between choosing to eat healthy food because you know it’s good for you versus choosing something just because it’s your favorite color. Logic helps you base your choices on what makes the most sense.

  • Critical Thinking: This is about judging information before you believe it or act on it. It’s about asking questions like, “Is this source trustworthy? Does this make sense?”
  • Argumentation Theory: This is the study of how to make a good argument and persuade people. It dives into what makes an argument solid or weak.
  • Computer Science: It’s not just about computers; it’s the study of algorithms, which are like recipes for getting computers to do what we want, and logic is a key ingredient.
  • Philosophy: This is the love of wisdom and big questions about life. It uses logic to ponder on and debate questions like “What is truth?”
  • Game Theory: Here’s where logic meets fun. Game theory uses logical principles to understand how and why people make decisions in competitive situations like sports or economics.


The roots of logic go way back to ancient thinkers like Aristotle, around 300 B.C. in Greece. Aristotle started putting together the puzzle of how arguments work and laid down some basic rules about reasoning. Since then, these ideas have grown and spread, becoming a key part of thinking about everything from language and math to science and art.


Even though logic seems like it should be clear-cut, it’s been a hot topic for debate. People question how much logic can actually tell us about the real world. There’s that tricky gap between a logical statement and the actual truth of how things work. Also, folks can’t always agree on what qualifies as ‘logical’ since logic can sometimes seem different depending on who you are or what you already think is true. Then there are those brain-bending paradoxes that don’t seem to have clear answers, no matter how logical you get.

Applied Logic in Daily Life

We use applied logic more than we realize, like when we’re managing our day to fit in all our activities or solving a tough math problem. It helps us decide if we’re being told the truth and even in fun things like planning how to save up for a video game. All these challenges need logic!

The Future of Applied Logic

Our world is only getting more complex, making applied logic more valuable than ever. It’s not just about ‘thinking correctly’ but also about breaking down and handling challenges that life throws at us. It’s a skill that will benefit us across different areas, from future jobs to personal decisions.

In Conclusion

Applied logic is the art of using our thought tools in the face of life’s everyday problems and questions. Getting to grips with it can boost how you do at school, how you’ll navigate your career, and how you make choices day-to-day. It’s about using that brainpower to find solutions and understanding—it’s your secret weapon to sifting through confusion and finding clarity.
