Are people getting more ignorant? People will talk of "critical thinking skills" as a virtue (they are). But then some folks conflate that with being a critic. They think if they can be a critic (and maybe even a witty and interesting critic, if only in their own minds, but even better if others think it's cool), then they somehow have excellent critical thinking skills. That's why I try to shift the idea over to "analytic thinking skills." You really can't have critique without analysis. If you do, then what you really have is an a**hole.
Also, in America at least, we focus on STEM. STEM produces good little producers and consumers. However, when you combine STEM with hunger, there is no way in hell the United States will ever compete with China and India. So, we should remember that which made us great in the first place, which is the Liberal Arts. If you arrive at STEM because you are hungry, you will never hold a candle to someone who arrives at STEM through deep-seated, fun and love of natural intellectual curiosity.
Nothing stimulates intellectual curiosity like the Liberal Arts. When you get a guy like Thomas Jefferson or some of the other men of the Enlightenment, and you raise them on Philosophy, the language arts and things like Latin and Greek, and history and political science and etc. then of course they will develop an interest in medicine, chemistry, geography, botany, etc. And those folks will always outshine the producers and consumers.
The brain is like a muscle and just because everyone has one, and every one's a critic, doesn't mean they know how to use it. Some resist education because they think they, or their kids, are being taught what to think. In reality, the liberal arts teaches how, not what.
So, the problem manifest in the local school district. Cletus comes home from a long, hard day at work. Hi sits down at the dinner table with his lovely family and happens to let out the smallest complaint. Then, little Bobby and Sally roll his socks in argument, probably some political shit, and Cletus gets pissed. He think those commie teachers at school are filling his kid's heads with liberal BS. So, when it comes time to support the mill levy for the school and education, he votes against it. Meanwhile, he's got his preacher thumbing the book and telling him what's what so his interest in education shifts that direction and things get worse.
So, I'm not so sure people are getting more ignorant. I think they always have been. However, I think in the past people were more inclined to read a book and, after a day of plowing (Yeoman Farmer) they were more willing to be humble and defer to the likes of Jefferson, et al.
What we need is a re-enlightenment. Our founding fathers were fans of public education. But now we have a plutocracy using their accumulated wealth to pick and choose which charity they want to give their money too. Since they aren't really taxed, they can afford to do that, while government is left to be the punching bag for all of societies failures and the plutocrats get to hold themselves out as these great benefactors of society. And the great unwashed swallow it, hook, line and sinker.
When I drive thought various towns and see the old Carnegie Library, I see an ancient memory of a modicum of enlightened self-interest. Self-interest now is sans the enlightenment. Milk those cattle for the last drop this quarter and move on.
Finally, I look around Europe and see them creeping ahead, because the have some enlightenment. And I look at the far and middle east and see the art and architecture we used to lead the world in. And we continue to rot. And we continue to blame the ivory tower intellectual elites and the liberals for all our ills. When, in fact, they could very well be our salvation.
Oh well. I do have some faith in the kids these days. On the rare occasion when I can pierce their mysterious lexicon and magic veil, I often see goodness, energy and enlightenment. If only they didn't have to lead themselves. If only they had worthy mentors. Nevertheless, I think they are going to pull it off. They may roll their eyes at our selfishness, but the too will develop their own skeletons and their own areas where they "knew better" and failed to do better. It's human.
