Use "unbefool" in a sentence
"A man's way out of error lies through the paths of conviction; and he that recovers a fool must first unbefool him to that degree, as to persuade him of his folly: for it is a thing against nature and reason for a man to think of amendment, who at the same time thinks himself perfect."
