This paper explores a perspective that expands the scope of the "healthy" n
arcissistic function to include the narcissistic preservation of self-ident
ities during interaction between self and others. After a brief review of t
he literature from Freud to current views on the subject, the author descri
bes the mutual influence of narcissistic processing and object relation and
goes on to theorize that self-preservation is accomplished by the narcissi
stic envelope through immunization and defensive processing. Narcissistic i
mmune processing provides familiarity, cohesiveness, equilibrium, integrity
, and continuity to the self's separateness in an affective state of stabil
ity, which may make the libidinal need for object relation and interrelatio
n with the world possible without undermining the constancy and safety of t
he self. The defensive processing preserves the self from incohesiveness an
d vulnerability during exposure to the unfamiliar (by creating a false self
-identity, withdrawing into a narcissistic state, or preventing new interac
tions). The theoretical implications of this argument and their practical a
pplication are illustrated by several clinical vignettes.
