James Frazer quotes - page 2
In primitive society the rules of ceremonial purity observed by divine kings, chiefs, and priests agree in many respects with the rules observed by homicides, mourners, women in childbed, girls at puberty, hunters and fishermen, and so on. To us these various classes of persons appear to differ totally in character and condition; some of them we should call holy, others we might pronounce unclean and polluted. But the savage makes no such moral distinction between them; the conceptions of holiness and pollution are not yet differentiated in his mind. To him the common feature of all these persons is that they are dangerous and in danger, and the danger in which they stand and to which they expose others is what we should call spiritual or ghostly, and therefore imaginary. The danger, however, is not less real because it is imaginary; imagination acts upon man as really does gravitation, and may kill him as certainly as a dose of prussic acid.
