[14] In young children, for instance, ambivalent emotional attitudes towards those who are nearest to them exist side by side for a long time, without either of them interfering with the expression of the other and contrary one. If eventually a conflict breaks out between the two, it often settled by the child making a change of object and displacing one of the ambivalent emotions on to a substitute. The history of the development of a neurosis in an adult will also show that a suppressed emotion may frequently persist for a long time in unconscious or even in conscious phantasies, the content of which naturally runs directly counter to some predominant tendency, and yet that this antagonism does not result in any proceedings on the part of the ego against what it has repudiated. The phantasy is tolerated for quite a long time, until suddenly one day, usually as a result of an increase in the affective cathexis [see footnote page 48] of the phantasy, a conflict breaks out between it and the ego with all the usual consequences. In the process of a child's development into a mature adult there is a more and more extensive integration of its personality, a co-ordination of the separate instinctive feelings and desires which have grown up in him independently of one another. The analogous process in the domain of sexual life has long been known to us as the co-ordination of all the sexual instincts into a definitive genital organisation.

[_Three Contributions to the Sexual Theory._ Nervous and Mental Disease Monograph Series, No. 7, 1910.]) Moreover, that the unification of the ego is liable to the same interferences as that of the libido is shown by numerous familiar instances, such as that of men of science who have preserved their faith in the Bible, and the like.
