‘There must therefore be another answer to the conundrum. I claim my own solution as original, though without the help of Sir James Frazer and the great Ibn Warraq I might not have hit upon it. According to many ancient authorities, the attitude of early Semites to swine was one of reverence as much as disgust. The eating of pig flesh was considered as something special, even privileged and ritualistic. (This mad confusion between the sacred and the profane is found in all faiths at all times.) The simultaneous attraction and repulsion derived from an anthropomorphic root: the look of the pig, and the taste of the pig, and the dying yells of the pig, and the evident intelligence of the pig, were too uncomfortably reminiscent of the human.
Porcophobia—and porcophilia—thus probably originate in a night-time of human sacrifice and even cannibalism at which the “holy” texts often do more than hint. Nothing optional—from homosexuality to adultery—is ever made punishable unless those who do the prohibiting (and exact the fierce punishments) have a repressed desire to participate. As Shakespeare put it in King Lear, the policeman who lashes the whore has a hot need to use her for the very offense for which he plies the lash.
Porcophilia can also be used for oppressive and repressive purposes. In medieval Spain, where Jews and Muslims were compelled on pain of death and torture to convert to Christianity, the religious authorities quite rightly suspected that many of the conversions were not sincere. Indeed, the Inquisition arose partly from the holy dread that secret infidels were attending Mass—where of course, and even more disgustingly, they were pretending to eat human flesh and drink human blood, in the person of Christ himself. Among the customs that arose in consequence was the offering, at most events formal and informal, of a plate of charcuterie. Those who have been fortunate enough to visit Spain, or any good Spanish restaurant, will be familiar with the gesture of hospitality: literally dozens of pieces of differently cured, differently sliced pig. But the grim origin of this lies in a constant effort to sniff out heresy, and to be unsmilingly watchful for giveaway expressions of distaste. In the hands of eager Christian fanatics, even the toothsome jamón Ibérico could be pressed into service as a form of torture.’
