Regarding fallacies, one might think: “What’s the big deal? Who cares about ’em?”
Here’s why you should care. In short, a fallacy is like an error in arithmetic.
Suppose you are balancing your budget, and you bungle your calculation. Your results will be mistaken. You might even bounce a check. Not good.
Similarly, if one commits an error in reasoning (i.e., a fallacy), one’s conclusion will bounce. Not good.
You might be living on bounced beliefs.
