There’s a common myth that the purpose of education is to teach you specific skills to use in your job. But that’s ridiculous, and for the most part, quite impossible. Even vocational programs can’t teach you how to do a job. Sure, they can teach you the skill of welding, but being a welder is something you can really only learn by being a welder.
The purpose of education, then, is not to teach you how to do your job. It’s to teach you how to learn. When I was in eighth grade, I had a smart and funny algebra teacher, Mr. R. During one lesson about some algebraic concept, one of the more obnoxious students in the class asked the same question that gets asked in every class: “why do we need to learn this? When are we ever going to use it in real life?”
Every teacher I’ve ever had always tried to come up with some contrived example to answer this question.
But Mr. R. just shrugged and said, “you probably won’t need to use it. But that’s not why we teach mathematics. We teach math because learning math teaches you how to think logically. Learning algebra in particular teaches you how to think about quantities and how they relate to one another, and by practicing it, you will automatically apply these skills to your every-day life, whether you’re aware that you’re doing algebra or not.”
That’s the idea that people seem to have forgotten about the liberal arts tradition in the past 50 years or so. Nobody expects deconstructing the the logic of ancient Roman rhetoric to be useful when you become a CPA. But learning to think about logical argument is useful in many endeavors, both personal and professional, and if you did a good job you’ll apply those skills without realizing it.
I’m also a self-taught programmer, having learned more in my first weeks on the job then I did in a year of CS classes (I dropped out.) But I don’t regret my “useless” education at all, and in fact I wish I had worked much harder at it when I was young. Certainly, I could never have taught myself as much as I did without the thinking skills I learned from my great high school and college teachers. Interestingly, a throwaway elective that I had no interest in (Psychology 101) probably taught me more about how to think about the scientific investigation and problem-solving than any hard science or math class did.
In conclusion, there are a metric shitload of people out there who assume that the purpose of a college education is to spend four years to buy a job. But they’re missing the point, and a lot of them probably don’t belong in college anyway. (I sure as shit didn’t back when I was there.) It took a long time for me to really get Mr. R.'s lesson.
