The United States is a mess right now. Beset by a corrupt president and his corporate cronies, plagued by a — um — plague, Americans are experiencing an attack on democracy from within. So just how did we get to this point in history?

I’ve given it a bit of thought, and I’ve come up with a theory. Like many theories, it’s built on a certain amount of critical observation and a large degree of personal experience. Marry those things to each other, and you can often explain even the most puzzling enigmas. Here, then, is my stab at explaining how American society became so divisive that agreement on any political topic has become virtually impossible, leaving a vaccuum so large and so empty that corruption and the will to power can ensure political victory.

I maintain that this ideological binarism in the United States is caused by two things: prejudice (racism has, in many ways, always determined our political reality), and lack of critical thinking skills (how else could so many people fail to see Trump for what he really is and what he really represents?) Both of these problems result from poor education. For example, prejudice certainly exists in all societies, but the job of a proper education in a free society is to eradicate, or at least to combat, prejudice and flawed beliefs. Similarly, critical thinking skills, while amorphous and hard to define, can be acquired through years of education, whether by conducting experiements in chemistry lab or by explicating Shakespeare’s sonnets. It follows, then, that something must be radically wrong with our educational system for close to half of the population of the United States to be fooled into thinking that Donald Trump can actually be good for this country, much less for the world at large.

In short, there has always been a possibility that a monster like Trump would appear on the political scene. Education should have saved us from having to watch him for the last four years, and the last month in particular, as he tried to dismantle our democracy. Yet it didn’t. So the question we have to ask is this: Where does the failure in education lie?

The trendy answer would be that this failure is a feature, not a bug, in American education, which was always designed to mis-educate the population in order to make it more pliable, more willing to follow demogogues such as Trump. But I’m not satisfied with this answer. It’s too easy, and more important, it doesn’t help us get back on track by addressing the failure (if that’s even possible at this point). So I kept searching for an explanation.

I’ve come up with the following premises. First, the divisions in the country are caused by a lack of shared values–this much is clear. For nearly half the American people, Trump is the apotheosis of greedy egotism, a malignant narcissist who is willing to betray, even to destroy, his country in order to get what he wants, so that he can “win” at the system. For the other half, Trump is a breath of fresh air, a non-politician who was willing to stride into the morass of Washington in order to clean it up and set American business back on its feet. These two factions will never be able to agree–not on the subject of Trump, and very likely, not on any other subject of importance to Americans.

It follows that these two views are irreconcilable precisely because they reflect a dichotomy in values. Values are the intrinsic beliefs that an individual holds about what’s right and wrong; when those beliefs are shared by a large enough group, they become an ethical system. Ethics, the shared sense of right and wrong, seems to be important in a society; as we watch ours disintegrate, we can see that without a sense of ethics, society splinters into factions. Other countries teach ethics as a required subject in high school classes; in the United States, however, only philosophy majors in universities ever take classes on ethics. Most Americans, we might once have said, don’t need such classes, since they experience their ethics every day. If that ever was true, it certainly isn’t so any more.

Yet I would argue that Americans used to have an ethical belief system. We certainly didn’t live up to it, and it was flawed in many ways, but it did exist, and that’s very different from having no ethical system at all. It makes sense to postulate that some time back around the turn of the 21st century, ethics began to disappear from society. I’m not saying that people became unethical, but rather that ethics ceased to matter, and as it faded away, it ceased to exist as a kind of social glue that could hold Americans together.

I think I know how this happened, but be warned: my view is pretty far-fetched. Here goes. Back in the 1970s and 1980s, literary theory poached upon the realm of philosophy, resulting in a collection of theories that insisted a literary text could be read in any number of ways, and that no single reading of a text was the authoritative one. This kind of reading and interpretation amounted to an attack on the authority of the writer and the dominant ideology that produced him or her, as it destabilized the way texts were written, read, and understood. I now see that just as the text became destabilized with this new way of reading, so did everything else. In other words, if an English professor could argue that Shakespeare didn’t belong in the literary canon any longer, that all texts are equally valid and valuable (I’ve argued this myself at times), the result is an attack not only on authority (which was the intention), but also on communality, by which I mean society’s shared sense of what it values, whether it’s Hamlet or Gilligan’s Island. This splintering of values was exacerbated by the advent of cable television and internet music sources; no one was watching or listening to the same things any more, and it became increasingly harder to find any shared ideological place to begin discussions. In other words, the flip side of diversity and multiplicity–noble goals in and of themselves–is a dark one, and now, forty years on, we are witnessing the social danger inherent in dismantling not only the canon, but any system of judgment to assess its contents as well.

Here’s a personal illustration. A couple of years ago, I taught a college Shakespeare class, and on a whim I asked my students to help me define characters from Coriolanus using Dungeons and Dragons character alignment patterns. It was the kind of exercise that would have been a smashing success in my earlier teaching career, the very thing that garnered me three teaching awards within five years. But this time it didn’t work. No one was watching the same television shows, reading the same books, or remembering the same historical events, and so there was no way to come up with good examples that worked for the entire class to illustrate character types. I began to see then that a splintered society might be freeing, but at what cost if we had ceased to be able to communicate effectively?

It’s not a huge leap to get from that Shakespeare class to the fragmentation of a political ideology that leaves, in the wreckage it’s produced, the door wide open to oligarchy, kleptocracy, and fascism. There are doubtless many things to blame, but surely one of them is the kind of socially irresponsible literary theory that we played around with back in the 1980s. I distinctly remember one theorist saying something to the effect that no one has ever been shot for being a deconstructionist, and while that may be true, it is not to say that deconstructionist theory, or any kind of theory that regards its work as mere play, is safe for the society it inhabits. Indeed, we may well be witnessing how very dangerous unprincipled theoretical play can turn out to be, even decades after it has held sway.
