In the conflict with which we are here concerned, those motives of a relatively social or ethical character which we have already considered in this chapter, act as the repressing force; while the original primitive tendencies of love and hate, with which we were concerned in the last chapter, suffer the repression. As regards the degree to which the repression is carried, it would appear that in a considerable number of cases the more strongly tabooed among the socially and ethically objectionable elements become forced out of consciousness without producing any immediate conscious equivalents. This, perhaps, is liable to take place more especially as regards some of the more directly sexual aspects of the child's attitude towards its parents. As Freud has pointed out[19] there occurs at some time in the early period of childhood--perhaps most usually at about the sixth year, a relatively latent sexual period, during which all sexual manifestations are more or less in abeyance. The existence of this period would seem to imply a temporary general sexual repression, in which the erotic aspects in the affection of the child to its parents suffer, together with all other sexual elements. This initial period of repression seems to play an important part in the production of a permanent dissociation between the sexual desires and the feelings experienced in relation to the parents, so that sexual emotion and filial affection are thereafter seldom permitted to enter consciousness together. Indeed it would appear that this general repression of sexual activity is to some extent removed only in so far as this dissociation has taken place; for on the reappearance of a more vigorous sexuality at the close of the latent period, the erotic tendencies would seem normally to have undergone a process of displacement so that they are no longer so intimately connected with the parent-love as on their first appearance.
