Mental Road Maps and the Art of Reasoning

“You’re not wrong, but you are incorrect.”

This phrase, cheekily spoken by my friend, sums up about how I’ve been feeling the last few weeks as I’ve encountered a surprising number of logical fallacies in one of my textbooks.

Logic is important to me. I spent too much time learning to recognize illogic in my former beliefs and struggling to reconcile the cognitive dissonance of being told to believe two contradictory ideas to merely shrug my shoulders when I encounter it elsewhere.

I try not to harass people too much if their personal beliefs and conversations fail to match up logically…usually; however, I expect more from a textbook that is supposed to be teaching me the art of making ethical decisions.

Ultimately, it probably won’t make a big difference in the grand scheme of the universe for me to write this post. It’s not like my textbook authors will read my blog and think, “Oh, shit, she’s right! Logic is super important. Let’s recall all the books and rewrite them.”

However, there’s value in catharsis (which I didn’t need a textbook to tell me), and there’s also the chance that maybe someone will read this and take it to heart. Butterfly wings and hurricanes and all that, right?

So, what is logic? Why is it important?

Logic is the road that connects ideas together. It’s not so much a philosophy on its own (although there is a philosophical study on logic) as it is the glue that binds any type of reasoning together.

We all use it on a pretty daily basis without thinking about it. Every time you choose not to step in front of a car because you realize that it will likely hit you and injure you, you’re using logic.

Some logical lines of reasoning are so easy that you don’t really need to think them through because you’ve done so many times before. Metaphorically speaking, you don’t pull your GPS out every time you have to run to the grocery store because you already know the route.

However, what if you want to go on a longer mental road trip, so to speak? That’s where logical reasoning is very important. You could, for instance, drive from New York to Virginia on I-95. You will need to have a map, know where you’re trying to go, and pay attention to the route and signs along the way so that you don’t get lost, but you can get there because I-95 connects both states.

You could not, however, get to San Diego on I-95 because I-95 doesn’t go there.

Logic is the road you travel on.

It doesn’t tell you where you should go. It has absolutely no value judgment on your starting place or ending place. It merely tells you whether you can get from point A to point B.

Of course, this is a very simplistic illustration, but I hope you get the idea.

Logic is necessary for everything from building a hypothesis to designing a car to solving crimes. Being illogical doesn’t necessarily mean that the conclusion is wrong, but it does mean that the process is incorrect and that any conclusions drawn from that process are suspect. A doctor could, for instance, accidentally stumble upon the cure for a disease by making a couple of errors in the treatment, but that doesn’t mean he developed the cure any more than a child who guesses correctly on a math test has “solved” a problem.

And I hope we would all cringe to think of that doctor proceeding to teach his “cure” to students without actually figuring out or understanding what it was that worked so well.

So you see, logic is imperative, not only on an individual level to know that something makes sense, but also on a societal or educational level to ensure that valid principles are being passed on. Logic is the first reality check: “Is this possible?” “Does this make sense?” It has to pass before “Is this true?” or “Is this good?” can be answered.
