There is scarcely room for doubt that something in the psychological relation of a mother-in-law to a son-in-law breeds hostility between them and makes it hard for them to live together.

What is a totem? It is as a rule an animal (whether edible and harmless or dangerous and feared) and more rarely a plant or a natural phenomenon (such as rain or water), which stands in a peculiar relation to the whole clan.
