Here libido and ego-interest share the same fate and have once more become indistinguishable from each other. The familiar egoism of the sick person … - Sigmund Freud

The behavior of a human being in sexual matters is often a prototype for the whole of his other modes of reaction in life.

The sexual wishes in regard to the mother become more intense and the father is perceived as an obstacle to the mother; this gives rise to the Oedipus complex.

The ordinary man cannot imagine this Providence in any other form but that of a greatly exalted father, for only such a one could understand the needs of the sons of men, or be softened by their prayers and placated by the signs of their remorse. The whole thing is so patently infantile, so incongruous with reality, that to one whose attitude to humanity is friendly it is painful to think that the great majority of mortals will never be able to rise above this view of life. It is even more humiliating to discover what a large number of those alive today, who must see that this religion is not tenable, yet try to defend it inch by inch, as if with a series of pitiable rearguard actions.
