Seneca · On darkness as a veil for wickedness
Letters 122.18
The chief cause, however, of this disease seems to me to be a squeamish revolt from the normal existence. Just as such persons mark themselves off from others in their dress, or in the elaborate arrangement of their dinners, or in the elegance of their carriages; even so they desire to make themselves peculiar by their way of dividing up the hours of their day. They are unwilling to be wicked in the conventional way, because notoriety is the reward of their sort of wickedness. Notoriety is what all such men seek—men who are, so to speak, living backwards.
Seneca, Letters to Lucilius 122.18, translated by Richard Mott Gummere
