On the other hand, one finds a mental sensitivity equally pronounced. People who are always in fear lest somebody should find fault with them, with their mode of behaviour, with their manner of dress, even with their habit of thought. Unconsciously, to themselves they are the acme of perfection, they are the centre of importance, and they are inclined to think that people are paying very much more attention to them than is actually the case. They may consciously realise that they are not important at all, that other people do not give them a thought; but their unconscious Narcissism will not accept this slight upon their importance, and they remain miserably self-conscious in all their acts, reacting with exaggerated feeling whenever some slight criticism of their thoughts and actions appear even to be implied. Pride, vanity, and self importance are other manifestations of this temperament. The person who feels slighted, or whose feelings are hurt when other persons think too little of his opinions, or pay too little attention to his actions, or, in fact, whose feelings are hurt easily by anything whatsoever, is for the most part a Narcissist, in whom once again the infantile omnipotence has been disturbed. Jealousy very often represents the Narcissistic idea. The “dog-in-the-manger” attitude, which finding it cannot possess for itself, cannot bear anybody else to possess, is largely the attitude of unconscious phantasy, in which the individual cannot relinquish the idea that somehow he will succeed by means of his omnipotent mind in possessing the desired object, and his unconscious mind retains this idea so long as the object has not become the property of somebody else in such a definite and irrefutable manner as to prove in spite of his unconscious phantasy that he cannot possibly possess it himself. The “dog-in-the-manger” attitude is one which simply refuses to recognise the impossibility of possessing something, although the desire for possession in any particular case may unconsciously mean nothing except the desire to prove to oneself one’s own omnipotence. And many a case of jealousy in love-affairs is nothing but this unconscious desire to prove to oneself the possession of power; it is the hatred of acknowledging the fact that one has not control where one desires to have it most. Curious as it may seem jealousy is bred mostly out of self-love rather than out of love for the other person, although, of course, except in extreme cases, love for the other person may also exist.
