Reading, writing, and mathematics. Once called reading, and ‘riting, and ‘rithmetic in a 1907 popular tune called “School Days.”
That’s it. That’s what you need to become a lifelong learner. All the other stuff—driver’s ed, sex ed, whatever ed—is just fluff. The hardcore subjects are reading, writing, and math.
Think about it. If you can read with comprehension, write effectively, and understand mathematics up to, let’s say, trigonometry and advanced algebra, the world is your oyster. You can tackle history, psychology, literature, art appreciation, French or any other foreign language, biology, physics, chemistry, and any other subject that appeals to you. If you want to delve deeper into mathematics, well, you have the preparation to do so. Moreover, if you can read, write, and understand mathematics, you can find gainful employment.
So what are educated citizens?
