The concept of guilt is found most powerfully developed even in the most primitive communal forms which we know... the man is guilty who violates one of the original laws which dominate the society and which are mostly derived from a divine founder; the boy who is accepted into the tribal community and learns its laws, which bind him thenceforth, learns to promise; this promise is often given under the sign of death, which is symbolically carried out on the boy, with a symbolical rebirth.
