In connection with this question of being in love we have always been struck by the phenomenon of sexual over-estimation--the fact that the loved object enjoys a certain amount of freedom from criticism, and that all its characteristics are valued more highly than those of people who are not loved, or than its own were at a time when it itself was not loved. If the sensual tendencies are somewhat more effectively repressed or set aside, the illusion is produced that the object has come to be sensually loved on account of its spiritual merits, whereas on the contrary these merits may really only have been lent to it by its sensual charm. The tendency which falsifies judgement in this respect is that of _idealisation_. But this makes it easier for us to find our way about. We see that the object is being treated in the same way as our own ego, so that when we are in love a considerable amount of narcissistic libido overflows on to the object. It is even obvious, in many forms of love choice, that the object serves as a substitute for some unattained ego ideal of our own. We love it on account of the perfections which we have striven to reach for our own ego, and which we should now like to procure in this roundabout way as a means of satisfying our narcissism. If the sexual over-estimation and the being in love increase even further, then the interpretation of the picture becomes still more unmistakable. The tendencies whose trend is towards directly sexual satisfaction may now be pushed back entirely, as regularly happens, for instance, with the young man's sentimental passion; the ego becomes more and more unassuming and modest, and the object more and more sublime and precious, until at last it gets possession of the entire self-love of the ego, whose self-sacrifice thus follows as a natural consequence. The object has, so to speak, consumed the ego. Traits of humility, of the limitation of narcissism, and of self-injury occur in every case of being in love; in the extreme case they are only intensified, and as a result of the withdrawal of the sensual claims they remain in solitary supremacy. This happens especially easily with love that is unhappy and cannot be satisfied; for in spite of everything each sexual satisfaction always involves a reduction in sexual over-estimation. Contemporaneously with this 'devotion' of the ego to the object, which is no longer to be distinguished from a sublimated devotion to an abstract idea, the functions allotted to the ego ideal entirely cease to operate. The criticism exercised by that faculty is silent; everything that the object does and asks for is right and blameless. Conscience has no application to anything that is done for the sake of the object; in the blindness of love remorselessness is carried to the pitch of crime. The whole situation can be completely summarised in a formula: _The object has taken the place of the ego ideal._
