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. In the first place, the totem is the common ancestor of the clan; at the same time it is their guardian spirit and helper, which sends them oracles and, if dangerous to others, recognizes and spares its own children.
Sigmund FreudIn the development of mankind as a whole, just as in individuals, love alone acts as the civilizing factor in the sense that it brings a change from egoism to altruism.
