QUOTE : This new view, that the instincts fall into two groups, seems to explode the earlier construction of the successive stages of libidinal organization. But we do not have to break fresh ground in order to find a way out of the difficulty. The solution has been at hand for a long time and lies in the fact that what we are concerned with are scarcely ever pure instinctual impulses but mixtures in various proportions of the two groups of instincts. If this is so, there is no need to revise our view of the organizations of the libido. A sadistic cathexis of an object may also legitimately claim to be treated as a libidinal one; and an aggressive impulse against the father can just as well be subjected to repression as a tender impulse towards the mother.
