Letter 45 — On Sophistical Argumentation (§8)

“Then, too, the man who is asked whether he has horns on his head is not such a fool as to feel for them on his forehead, nor again so silly or dense that you can persuade him by means of argumentation, no matter how subtle, that he does not know the facts. Such quibbles are just as harmlessly deceptive as the juggler’s cup and dice, in which it is the very trickery that pleases me. But show me how the trick is done, and I have lost my interest therein. And I hold the same opinion about these tricky word-plays; for by what other name can one call such sophistries? Not to know them does no harm, and mastering them does no good.”
