“All neurotics, and many others besides, take exception to the fact that 'inter urinas et faeces nascimur.”

“No neurotic harbors thoughts of suicide which are not murderous impulses against others redirected upon himself.”

“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.”

“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.”

“If we are to take it as a truth that knows no exception that everything dies for internal reasons – becomes inorganic once again – then we shall be compelled to say that ‘the aim of all life is death’ and, looking backwards, that ‘inanimate things existed before living ones’.”

“Dream's evanescence, the way in which, on awakening, our thoughts thrust it aside as something bizarre, and our reminiscences mutilating or rejecting it—all these and many other problems have for many hundred years demanded answers which up till now could never have been satisfactory.”

“The freeing of an individual, as he grows up, from the authority of his parents is one of the most necessary though one of the most painful results brought about by the course of his development. It is quite essential that that liberation should occur and it may be presumed that it has been to some extent achieved by everyone who has reached a normal state. Indeed, the whole progress of society rests upon the opposition between successive generations. On the other hand, there is a class of neurotics whose condition is recognizably determined by their having failed in this task.”
