The taboo restrictions are different from religious or moral prohibitions. They are not traced to a commandment of a god but really they themselves impose their own prohibitions; they are differentiated from moral prohibitions by failing to be included in a system which declares abstinences in general to be necessary and gives reasons for this necessity. The taboo prohibitions lack all justification and are of unknown origin. Though incomprehensible to us they are taken as a matter of course by those who are under their dominance.
