Everyone owes nature a death. - Sigmund Freud

Thus we arrive at the singular conclusion that of all the information passed by our cultural assets it is precisely the elements which might be of the greatest importance to us and which have the task of solving the riddles of the universe and of reconciling us to the sufferings of life — it is precisely those elements that are the least well authenticated of any.

Here is yet another important consideration for
helping us to understand the individual in a group:
Moreover, by the mere fact that he forms part of
an organised group, a man descends several rungs
in the ladder of civilization. Isolated, he may be a
cultivated individual; in a crowd, he is a barbarian — that is, a creature acting by instinct. He possesses
the spontaneity, the violence, the ferocity, and also
the enthusiasm and heroism of primitive beings.
He then dwells especially upon the lowering in
intellectual ability which an individual experiences when
he becomes merged in a group.

The ego is not master in its own house.
