Pathological narcissism is a defense mechanism intended to isolate the narcissist from his environment and to shield him from hurt and injury, both real and imagined. Hence the False Self - an all-pervasive psychological construct which gradually displaces the narcissist's True Self. It is a work of fiction intended to elicit praise and deflect criticism.
The unintended consequence of this fictitious existence is a diminishing ability to grasp reality correctly and to cope with it effectively. Narcissistic Supply replaces genuine, veritable, and tested feedback. Analysis, disagreement, and uncomfortable facts are screened out. Layers of bias and prejudice distort the narcissist's experience.
Yet, deep inside, the narcissist is aware that his life is an artifact, a confabulated sham, a vulnerable cocoon. The world inexorably and repeatedly intrudes upon these ramshackle battlements, reminding the narcissist of the fantastic and feeble nature of his grandiosity. This is the much-dreaded Grandiosity Gap.
To avoid the agonizing realization of his failed, defeat-strewn, biography, the narcissist resorts to reality-substitutes. The dynamics are simple: as the narcissist grows older, his Sources of Supply become scarcer, and his Grandiosity Gap yawns wider. Mortified by the prospect of facing his actuality, the narcissist withdraws ever deeper into a dreamland of concocted accomplishments, feigned omnipotence and omniscience, and brattish entitlement.
The narcissist's reality substitutes fulfill two functions. They help him "rationally" ignore painful realities with impunity - and they proffer an alternative universe in which he reigns supreme and emerges triumphant.
The most common form of denial involves persecutory delusions. I described these elsewhere:
"(The narcissist) perceives slights and insults where none were intended. He becomes subject to ideas of reference (people are gossiping about him, mocking him, prying into his affairs, cracking his e-mail, etc.). He is convinced that he is the centre of malign and mal-intentioned attention. People are conspiring to humiliate him, punish him, abscond with his property, delude him, impoverish him, confine him physically or intellectually, censor him, impose on his time, force him to action (or to inaction), frighten him, coerce him, surround and besiege him, change his mind, part with his values, even murder him, and so on."
The narcissist's paranoid narrative serves as an organizing principle. It structures his here and now and gives meaning to his life. It aggrandizes him as worthy of being persecuted. The mere battle with his demons is an achievement not to be sniggered at. By overcoming his "enemies", the narcissist emerges victorious and powerful.
The narcissist's self-inflicted paranoia - projections of threatening internal objects and processes - legitimizes, justifies, and "explains" his abrupt, comprehensive, and rude withdrawal from an ominous and unappreciative world . The narcissist's pronounced misanthropy - fortified by these oppressive thoughts - renders him a schizoid, devoid of all social contact, except the most necessary.
But even as the narcissist divorces his environment, he remains aggressive, or even violent. The final phase of narcissism involves verbal, psychological, situational (and, mercifully, more rarely, physical) abuse directed at his "foes" and "inferiors". It is the culmination of a creeping mode of psychosis, the sad and unavoidable outcome of a choice made long ago to forego the real in favor of the surreal.
