Seneca · On the relativity of fame
Letters 43.4
I shall mention a fact by which you may weigh the worth of a man’s character: you will scarcely find anyone who can live with his door wide open. It is our conscience, not our pride, that has put doorkeepers at our doors; we live in such a fashion that being suddenly disclosed to view is equivalent to being caught in the act. What profits it, however, to hide ourselves away, and to avoid the eyes and ears of men?
Seneca, Letters to Lucilius 43.4, translated by Richard Mott Gummere
