Let’s Be Reasonable about It

Without logic, our thought is always at risk—the risk of inconsistency, the risk that our ideas will not fit together but rather will contradict each other, the risk of becoming a mere hobgoblin of ideas like a cluttered garage. Logic is about consistency, about how things do or do not fit together. Above all, it is about what can or cannot follow from any given starting point.

Contrary to popular belief, everything is logical. Later, I will have more to say about this claim. Meanwhile, since everything follows from something else, anything is open to logical clarification.

Logic is not different from the Dialectic. It is a particular and rigorous instance of dialectical thinking. (Interestingly, math is a particular and extremely rigorous instance of logic.)

If we are going to talk about good thinking, that means that we will of necessity deal with logical thinking. Conventional wisdom says that good thinking is either logical or critical thinking. Yes, but it is more than this. We have seen that good thinking is dialectical thinking, considerate thinking. Good thinking is OTOH, BOTOH. On the other hand, logic, like bipolar thinking, is a particular form of the Dialectic. Although critical thinking—a ubiquitous but ambiguous concept, however you define it—is not what good thinking is all about, it is one part, one that we shall ignore because it is already implicit in all this book says.

The Dialectic is the only way to become a good thinker, but, on the other hand, logic is a valuable assistant. As noted earlier, in the Sears, Roebuck and Co. catalogs of the 1930s and ’40s, many items were available in three different qualities and priced accordingly: good, better, and best. For instance, we could buy a “good” shirt, or a “better one,” or their “best.” The
