(b) Moralists disagree on the question whether certain forms of defamation are distinct sub-species or only degrees of one lowest species. Some hold that detraction and calumny are distinct species, because calumny adds mendacity to defamation; others say that detractions about specifically different sins are distinct kinds of detraction (e.g., that it is one species of sin to say that a neighbor is a drunkard, and another species to say that he is a thief, and the reason is that the reputation for temperance is a different thing from the reputation for honesty, etc.); still others hold that defamation of parents and other immediate relations is a special form of defamation, as being contrary to piety. There are, on the contrary, theologians who reject all these distinctions and hold that the difference between defamations is only one of more or less, since all of them have the characteristic note of attack on reputation, which is one right. Hence, just as the stealing of a cow and the stealing of a cat are only greater and lesser forms of the sin of theft, so likewise calumny and detraction, etc., are only major and minor degrees of the sin of defamation (see 2012, 2013, 2115).
2040. Species of Sins of Defamation.—Since the species of sins must be particularized in confessions, the question of the distinction between defamations has practical importance. The common opinion on the line of action to be observed seems to be as follows:
(a) the penitent is obliged as a rule in serious matters to tell whether his defamation was simple detraction or calumny. The reason for this, according to some, is the specific difference between these two sins; according to others, the reason is that otherwise the confessor cannot know whether the sin was mortal or venial, or what restitution is to be imposed. As to detraction of parents or superiors, it seems that the quality of the person detracted should be mentioned, if there was any incitement to disrespect or disobedience;
(b) the penitent is not obliged to mention the sins or defects he ascribed to the person he defamed. Nor should the confessor inquire about this unless it is necessary in order to know what was the gravity of the sin or what kind of reparation should be enjoined (cfr. 2013). Moreover, questions about what was said might easily lead to a disclosure of the name of the person defamed, and thus the confessional would be turned into a place of defamation.
2041. The Numerical Multiplication of Defamations.—(a) They are multiplied when there are many sinful acts about distinct objects; for example, when Balbus calumniates Caius today as a thief and Claudius tomorrow as another thief, there are two calumnies (see 209).
(b) Defamations are multiplied when there are many sinful acts about the same object; for example, when Balbus calumniates Caius today as a thief and repeats the same calumny tomorrow, there are two calumnies. But if Balbus begins his story today and does not finish it till tomorrow, there is one calumny (see 214, 215).
(c) Defamations are multiplied when there is one sinful act about many distinct objects; for example, when Balbus calumniates by saying that the two worst thieves he knows are Caius and Claudius, there are two sins. But if Caius and Claudius are regarded as a unit (e.g., if they are the firm of Caius and Claudius), there is one sin. A like calumny would be that Caius came from a dishonest family (see 216-219). If Balbus calumniates Caius before ten persons, he does not commit ten defamations, it seems, but ten scandals, since the ten form a body in the matter of fame, but are individuals in the matter of example. If Balbus calumniates by saying that Caius has broken all of the ten commandments, there may be ten calumnies or but one calumny, according to the intention and the effect (see 217, 218).
2042. The Theological Species of Defamation.—(a) From its nature defamation is a mortal sin, and hence the Apostle declares (Rom, i. 29, 30) that detractors are hateful to God. In the first place, it inflicts an atrocious injury on the public welfare, sowing everywhere hatreds, dissensions and disorders—so much so that detractors are rightly called an abomination to mankind (Prov., xxiv. 9).
(b) From the smallness of the matter or the imperfection of the act defamation may be only a venial sin. Criticism of others is a vice so widespread that almost all mankind (even pious persons) would be involved in continual mortal sins, were it not for the fact that sins of speech are frequently the result of ignorance, thoughtlessness, or sudden passion (James, iii. 2 sqq.), and that the things said are frequently of no great harm to the person criticized.
2043. The gravity of the harm done by defamation is well expressed by St. Bernard when he says that defamation at one blow inflicts a mortal Wound on the person defamed, on the defamer himself, and on the listener.
