This first configuration of the child's love, which in typical cases is co-ordinated with the Oedipus complex, succumbs, as we know, from the beginning of the period of latency onwards to a wave of repression. Such of it as is left over shows itself as a purely tender emotional tie, which relates to the same people, but is no longer to be described as 'sexual'. Psycho-analysis, which illuminates the depths of mental life, has no difficulty in showing that the sexual ties of the earliest years of childhood also persist, though repressed and unconscious. It gives us courage to assert that wherever we come across a tender feeling it is the successor to a completely 'sensual' object tie with the person in question or rather with that person's prototype (or _imago_). It cannot indeed disclose to us without a special investigation whether in a given case this former complete sexual current still exists under repression or whether it has already been exhausted. To put it still more precisely: it is quite certain that it is still there as a form and possibility, and can always be charged with cathectic energy and put into activity again by means of regression; the only question is (and it cannot always be answered) what degree of cathexis and operative force it still has at the present moment. Equal care must be taken in this connection to avoid two sources of error--the Scylla of under-estimating the importance of the repressed unconscious, and the Charybdis of judging the normal entirely by the standards of the pathological. A psychology which will not or cannot penetrate the depths of what is repressed regards tender emotional ties as being invariably the expression of tendencies which have no sexual aim, even though they are derived from tendencies which have such an aim.[71]
