“Then what should a man do, if he has sense and lays claim to probity or truthfulness?.” In my opinion he should do what Homer suggested in his parable of the Sirens. He bids us to sail past these deadly allurements and to stop our ears ; not to hold them wide open to men prejudiced by passion, but, setting Reason as a strict doorkeeper over all that is said, to welcome and admit what deserves it, but shut out and drive off what is bad. For surely, it would be ridiculous to have doorkeepers to guard your house, but to leave your ears and your mind wide open.
