Scripture is clear—Proverbs in particular—that there are such things as fools and these individuals are nothing but trouble. We shouldn’t be in their company more than necessary—much less, put important responsibilities in their hands.
Though the English word “fool” appears 60 to 65 times in most English versions of Proverbs, the book doesn’t offer a concise definition. That leaves us with some ambiguity. How many of the traits of fools does someone have to have to be rightly classified as a fool? Are we supposed to take the qualities of fools only as way to gauge the degree of foolishness?
Though we’re all foolish at times, the fool is consistently spoken of in Proverbs as belonging to a distinct category. There may be degrees of severity, but either someone is a fool, or he isn’t.
It’s probably best to approach the question of who’s a fool sort of like a disease: how many symptoms do you have to have in order to be diagnosed as having, say, rabies? Though I’m often a little photo-phobic, cranky, and confused, the probability remains low that I’m rabid. On the other hand, if somebody has six of the usual symptoms of rabies but is not oversensitive to light, probability remains high that they’re infected.
The more symptoms, the more confident the diagnosis, and you don’t need all of them to be pronounced a fool.
