It is well known that there are people the general colour of whose mood oscillates periodically from an excessive depression through some kind of intermediate state to an exalted sense of well-being. These oscillations appear in very different degrees of amplitude, from what is just noticeable to those extreme instances which, in the shape of melancholia and mania, make the most painful or disturbing inroads upon the life of the person concerned. In typical cases of this cyclical depression outer exciting causes do not seem to play any decisive part; as regards inner motives, nothing more (or nothing different) is to be found in these patients than in all others. It has consequently become the custom to consider these cases as not being psychogenic. We shall refer later on to those other exactly similar cases of cyclical depression which can nevertheless easily be traced back to mental traumata.
Thus the foundation of these spontaneous oscillations of mood is unknown; we are without insight into the mechanism of the displacement of a melancholia by a mania. So we are free to suppose that these patients are people in whom our conjecture might find an actual application—their ego ideal might be temporarily resolved into their ego after having previously ruled it with especial strictness.
Let us keep to what is clear: On the basis of our analysis of the ego it cannot be doubted that in cases of mania the ego and the ego ideal have fused together, so that the person, in a mood of triumph and self-satisfaction, disturbed by no self-criticism, can enjoy the abolition of his inhibitions, his feelings of consideration for others, and his self-reproaches. It is not so obvious, but nevertheless very probable, that the misery of the melancholiac is the expression of a sharp conflict between the two faculties of his ego, a conflict in which the ideal, in an excess of sensitiveness, relentlessly exhibits its condemnation of the ego in delusions of inferiority and in self-depreciation. The only question is whether we are to look for the causes of these altered relations between the ego and the ego ideal in the periodic rebellions, which we have postulated above, against the new institution, or whether we are to make other circumstances responsible for them.
A change into mania is not an indispensable feature of the symptomatology of melancholic depression. There are simple melancholias, some in single and some in recurring attacks, which never show this development. On the other hand there are melancholias in which the exciting cause clearly plays an aetiological part. They are those which occur after the loss of a loved object, whether by death or as a result of circumstances which have necessitated the withdrawal of the libido from the object. A psychogenic melancholia of this sort can end in mania, and this cycle can be repeated several times, just as easily as in a case which appears to be spontaneous. Thus the state of things is somewhat obscure, especially as only a few forms and cases of melancholia have been submitted to psycho-analytical investigation.[64] So far we only understand those cases in which the object is given up because it has shown itself unworthy of love. It is then set up again inside the ego, by means of identification, and severely condemned by the ego ideal. The reproaches and attacks directed towards the object come to light in the shape of melancholic self-reproaches.[65]
A melancholia of this kind may also end in a change to mania; so that the possibility of this happening represents a feature which is independent of the other characteristics in the symptomatology.
Nevertheless I see no difficulty in assigning to the factor of the periodical rebellion of the ego against the ego ideal a share in both kinds of melancholia, the psychogenic as well as the spontaneous. In the spontaneous kind it may be supposed that the ego ideal is inclined to display a peculiar strictness, which then results automatically in its temporary suspension. In the psychogenic kind the ego would be incited to rebellion by ill-treatment on the part of its ideal—an ill-treatment which it encounters when there has been identification with a rejected object.

POSTSCRIPT
In the course of the enquiry which has just been brought to a provisional end we came across a number of side-paths which we avoided pursuing in the first instance but in which there was much that offered us promises of insight. We propose now to take up a few of the points that have been left on one side in this way.
A. The distinction between identification of the ego with an object and replacement of the ego ideal by an object finds an interesting illustration in the two great artificial groups which we began by studying, the army and the Christian church.
It is obvious that a soldier takes his superior, that is, really, the leader of the army, as his ideal, while he identifies himself with his equals, and derives from this community of their egos the obligations for giving mutual help and for sharing possessions which comradeship implies. But he becomes ridiculous if he tries to identify himself with the general. The soldier in Wallensteins Lager laughs at the sergeant for this very reason:
