It is superfluous to refer to Socrates, misrepresented to the Athenians as an impious plotter, to Themistocles or Miltiades, suspected after all their victories of betraying Greece; such examples are innumerable, and most of them familiar. What, then, should a man of sense do, when he finds one friend’s virtue pitted against another’s truth? Why, surely, learn from Homer’s parable of the Sirens; he advises sailing past these ear-charmers; we should stuff up our ears; we should not open them freely to the prejudiced, but station there a competent hall-porter in the shape of Judgement, who shall inspect every vocal visitor, and take it on himself to admit the worthy, but shut the door in the face of others. How absurd to have such an official at our house door, and leave our ears and understandings open to intrusion!
