The difference between narcissism and self-love is a matter of depth. Narcissus falls in love not with the self, but with an image or reflection of the self — with the persona, the mask. The narcissist sees himself through the eyes of another, changes his lifestyle to conform with what is admired by others, tailors his behavior and expression of feelings to what will please others. Narcissism is eye trouble, voluntary blindness, an agreement to keep up appearances (hence the importance of “style”) and not to look beneath the surface.
