Translation: religion is to civilization as adolescence is to indivdual development. It is a necessary stage civilization goes through to get from immaturity to adulthood. Immaturity being tribal and superstitious and maturity being rationality?
I don’t agree with Freud if the sense of what he is saying is something like the above. Religion and rationalty are wrapped around one another like strands of DNA and are not either/or propositions, rather they enhance and play off of one another, each necessary for the existence of the other.
