"Conscience draws the Picture of the Crime in Apparition just before him, and the Reflection, not the injur'd Soul, is the Spectre that haunts him: Nor can he need a worse Tormenter in this Life; whether there is a worse hereafter, or no, I do not pretend to determine. This is certainly 'a Worm that never dies'; 'tis always gnawing the Vitals, not of the Body, but of the very Soul—But I say, here was no Apparition all this while of any kind, no Spectre, no Ghost, no not to detect a Murtherer."
— Defoe, Daniel (1660?-1731)
