Whatever the child's initial reaction, though, the point to notice is that we eat animal flesh long before we are capable of understanding that what we are eating is the dead body of an animal. Thus we never make a conscious, informed decision, free from the bias that accompanies any long-established habit, reinforced by all the pressures of social conformity to eat animal flesh. At the same time, children have a natural love of animals, and our society encourages them to be affectionate toward animals such as dogs and cats and toward cuddly, stuffed animals. These facts help to explain that most distinctive characteristic of the attitudes of children in our society to animals - namely, that rather than having one unified attitude to animals, the child has two conflicting attitudes that coexists, carefully segregated so that the inherent contradiction between them rarely causes trouble.
