Chassenée endeavours to clinch his argument as usual by quoting biblical texts and adducing incidents from legendary literature. The province of zoö-psychology, which would have furnished him with better material for the elucidation of his subject, he leaves untouched, simply because it was unknown to him. If crime consists in the commission of deeds hurtful to other sentient beings, knowing such actions to be wrong, then the lower animals are certainly guilty of criminal offences. It is a well-established fact, that birds, beasts and insects, living together in communities, have certain laws, which are designed to promote the general welfare of the herd, the flock or the swarm, and the violation of which by individual members they punish corporally or capitally as the case may require. It is likewise undeniable, that domestic animals often commit crimes against man and betray a consciousness of the nature of their acts by showing fear of detection or by trying to conceal what they have done. Man, too, recognizes their moral responsibility by inflicting chastisement upon them, and sometimes feels justified in putting incorrigible offenders, a vicious bull, a thievish cat or a sheep-killing dog, summarily to death. Of course this kind of punishment is chiefly preventive, nevertheless it is provoked by acts already perpetrated and is not wholly free from the element of retributive justice. Such a proceeding, however, is arbitrary and autocratic, and if systematically applied to human beings would be denounced as intolerable tyranny. Chassenée insists that under no circumstances is a penalty to be imposed except by judicial decision--_nam poena nunquam imponitur, nisi lex expresse dicat_--and in support of this principle refers to the apostle Paul, who declares that “sin is not imputed when there is no law.” He appears to think that any technical error would vitiate the whole procedure and reduce the ban of the Church to mere _brutum fulmen_. If he lays so great stress upon the observance of legal forms, which in the criminal prosecution of brute beasts strike us as the caricature and farce of justice, it is because he deems them essential to the effectiveness of an excommunication. The slightest mispronunciation of a word, an incorrect accentuation or false intonation in uttering a spell suffices to dissolve the charm and nullify the occult workings of the magic. The lack of a single link breaks the connection and destroys the binding force of the chain; everything must be “well-thought, well-said and well-done,” not ethically, but ritually, as prescribed in the old Avestan formula: _humata hûkhta huvarshta_. All the mutterings and posturings, which accompany the performance of a Brahmanical sacrifice, or a Catholic mass, or any other kind of incantation have their significance, and none of them can be omitted without marring the perfection of the ceremonial and impairing its power.
