“I see them so well that they almost blind me. TRI. I believed hitherto that it was ignorance which made fools, and not knowledge. CLI. You made a great mistake; and I assure you that a learned fool is more of a fool than an ignorant one. TRI. Common sense is against your maxims, since an ignorant man and a fool are synonymous. CLI. If you cling to the strict uses of words, there is a greater connection between pedant and fool. TRI. Folly in the one shows itself openly. CLI. And study adds to nature in the other. TRI. Knowledge has always its intrinsic value.” source
