"Experience keeps a dear school," said Ben Franklin, "but fools will learn in no other." Unfortunately, experience�s curriculum is comprised almost exclusively of tests. That is why fools like me tend to have rudimentary knowledge about what to do while possessing a Pavlovian understanding of what not to do.
Because that is the case I thought I would share my insights on how not to argue. I would much prefer to write a series on the proper way to use logic and rhetoric but I haven't the faintest clue what that would entail. All I can offer is a set of heuristics, commonsense rules intended to increase the probability of solving some problem, which might help others avoid the tuition costs of experience's school for debate.
A heuristic, as Wikipedia usefully defines the term, is a way of directing your attention fruitfully. Because our cognitive abilities are finite, it often becomes necessary to find simple means of using such resources most effectively. Heuristics are not infallible, but they tend to provide suitable means of "directing our attention more fruitfully" to recurring problems we face.
An example of a rule of thumb that I find to be particularly useful in helping to avoid problems is to avoid, whenever possible, willfully stupid people. Intelligence is, of course, a relative concept and everyone (except for the World's Smartest Person) is just a little less bright than someone else. Willful stupidity, however, is distinct from IQ because it consists of a moral failing: Choosing to be dumber than you have to be.
One way to recognize a willfully stupid person is to examine the role hyperbole plays in their rhetoric. Take, for example, those who, like Pulitzer-nominated author Stephen Pizzo, say that "George Bush is the worst president of the United States of America, ever. Hands down." Whenever I encounter such people I walk the other way for fear that such stupidity might be contagious. For anyone to make such a claim would require a basic understanding of Presidential history, an objective standard for comparing other Presidents to George W, and an ability to make nuanced judgments. In other words, it requires the very skill set that would generally prevent a person from making such an inane claim in the first place.
