Neurosis is the inability to tolerate ambiguity.

Religion is comparable to a childhood neurosis

In so doing, the idea forces itself upon him that religion is comparable to a childhood neurosis, and he is optimistic enough to suppose that mankind will surmount this neurotic phase, just as so many children grow out of their similar neurosis.

Neurotics complain of their illness, but they make the most of it, and when it comes to taking it away from them they will defend it like a lioness her young.

We can postulate that there must be diseases founded on a conflict between ego and super-ego. Analysis gives us the right to infer that melancholia is the model of this group, and then we should put in a claim for the name of "narcissistic psychoneuroses" for these disorders.

Religion is an attempt to get control over the sensory world, in which we are placed, by means of the wish-world, which we have developed inside us as a result of biological and psychological necessities. But it cannot achieve its end. Its doctrines carry with them the stamp of the times in which they originated, the ignorant childhood days of the human race. Its consolations deserve no trust. Experience teaches us that the world is not a nursery. The ethical commands, to which religion seeks to lend its weight, require some other foundations instead, for human society cannot do without them, and it is dangerous to link up obedience to them with religious belief. If one attempts to assign to religion its place in man’s evolution, it seems not so much to be a lasting acquisition, as a parallel to the neurosis which the civilized individual must pass through on his way from childhood to maturity.
