It is like the Greek fire used in ancient warfare, which burnt unquenched beneath the water; or like the weeds which, when you have extirpated them in one place, are sprouting forth vigorously in another spot, at the distance of many hundred yards; or, to use the metaphor of St. James, it is like the wheel which catches fire as it goes, and burns with fiercer conflagration as its own speed increases. [ F. W. Robertson ]

Calumny is a monstrous vice: for, where parties indulge in it, there are always two that are actively engaged in doing wrong, and one who is subject to injury. The calumniator inflicts wrong by slandering the absent; he who gives credit to the calumny before he has investigated the truth is equally implicated. The person traduced is doubly injured - first by him who propagates, and secondly by him who credits the calumny. [ Heroidotus ]
