The construction of a collectively suitable persona means a formidable concession to the external world, a genuine self-sacrifice which drives the ego straight into identification with the persona, so that people really do exist who believe they are what they pretend to be. The “soullessness” of such an attitude is, however, only apparent, for under no circumstances will the unconscious tolerate this shifting of the centre of gravity. When we examine such cases critically, we find that the excellence of the mask is compensated by the ‘private life’ going on behind it. The pious Drummond once lamented that “bad temper is the vice of the virtuous.” Whoever builds up too good a persona for himself naturally has to pay for it with irritability. Bismarck had hysterical weeping fits, Wagner indulged in correspondence about the belts of silk dressing-gowns, Nietzsche wrote letters to his “dear lama,” Goethe held conversations with Eckermann, etc. But there are subtler things than the banal lapses of heroes. I once made the acquaintance of a very venerable personage – in fact, one might easily call him a saint. I stalked around him for three whole days, but never a mortal failing did I find in him. My feeling of inferiority grew ominous, and I was beginning to think seriously of how I might better myself. Then, on the fourth day, his wife came to consult me… Well, nothing of the sort has ever happened to me since. But this I did learn: that any man who becomes one with his persona can cheerfully let all disturbances manifest themselves through his wife without her noticing it, though she pays for her self-sacrifice with a bad neurosis.
These identifications with a social role are a very fruitful source of neuroses. A man cannot get rid of himself in favour of an artificial personality without punishment. Even the attempt to do so brings on, in all ordinary cases, unconscious reactions in the form of bad moods, affects, phobias, compulsive ideas, backslidings, vices, etc. the socially “strong man” is in his private life often a mere child where his own states of feeling are concerned; his public discipline (which he demands quite particularly of others) goes miserably to pieces in private. His “happiness in his work” assumes a woeful countenance at home; his “spotless” public morality looks very strange indeed behind the mask – we will not mention deeds, but only fantasies, and the wives of such men would have a pretty tale to tell. As to his selfless altruism, his children have decided views about that.
