There is a host of informal fallacies, so-called, that most of us commit unknowingly every day. The most common of them is the ad hominem fallacy in which a person’s claim is dismissed because of the type of person putting forth the claim. Thus, we might reject the claim made by Jones because Jones is a narrow-minded cretin. The fallacy arises because even though Jones may, in fact, be a narrow-minded cretin, his claim int this case might be well founded. Attention is drawn away from the claim to the person making the claim, Hence it is fallacious reasoning.

But there is another fallacy that is also quite common and perhaps even more insidious in its way. It’s called the fallacy of bifurcation. It rests on the fact that an argument relies on a false dichotomy to draw its conclusion. Most disjunctions are loose, non-exclusive disjunctions, as in “I will have either soup or a sandwich for lunch. ” (I might have both.) Lose disjunctions allow for the middle ground. Some disjunctions do not allow of any middle ground, as in “either you live in New York or you don’t.” You can’t have it both ways. These are called “exclusive disjunctions” and they are very rare (even in this case one could both live in New York and not live in New York if he or she had homes in both New York and Minnesota). There is seldom a situation that does not allow of a middle ground: most disjunctions are non-exclusive, as in the case with the soup or the sandwich.

What all this is leading to is the observation that we have all (or most of us) fallen for the notion put forward by the dirty energy companies that we must either have dirty energy or we must have a weak economy. It’s usually in the form “either jobs or the economy.” This is a classic example of the fallacy of bifurcation. Experience has shown — as though common sense would not — that we can have it both ways. We can have clean energy and boost the economy at the same time. This has been proven in the solar industry where thousands of jobs have been created and, as I recently argued, it has been shown in places like Chicago where 139,800 jobs have been created in the clean energy industry. And yet we will continue to hear from Big Oil, for example, that we simply must continue to destroy the earth by constructing monstrosities like the Keystone Pipeline because it creates jobs — the implication, again, is that the only industry that can provide jobs is the dirty energy industry. The argument is clearly self-serving. But it is also persuasive because, like all fallacies, it rests on an emotional appeal. People fear the loss of jobs and it is that fear (coupled with a weak critical faculty) that results in their acceptance of what is at heart a weak argument.

In addition to the appeal to emotion that rests at the heart of what amount to dozens of common fallacies which results in their being so persuasive there is the fact that we don’t teach logic to many people any more. We don’t teach many things that would help them gain control of their minds so that smiling, glad-handed thugs would not take possession of them. We don’t teach Latin much any more, despite the fact that knowing  Latin helps us gain a better grasp of our own language and since language is essential to thought, it is thought that suffers in the end. If one wonders why old-timers like myself keep going on about the demise of contemporary education it might be worth a moment to consider the fact that by focusing on what the children in the classrooms want and tossing out essential subjects like logic and Latin (and history, mathematics, economics, literature, and even English) we deprive the young today of the ability tomorrow to see the fallacies that lie at the heart of so many appeals by unconscionable agents whose only desire is to gain a profit or otherwise make life easy for themselves at our expense.

  1. It could be that the education system is more for the purpose of producing a workforce (i.e., basic literacy and numeracy) than a critical citizenry.

  2. Hugh, great post and great example. There was additional motive to why the president applauded Walmart’s solar powering initiative. As the largest employer in the world, they can make a difference in this area. IKEA, also powers 39 of its 43 US stores with its own solar energy. These are the stories that need to get out more to counter these bifurcation argument you note. Thanks, BTG
