Yeah, I'd have to agree with 'greynotreal' up there, in general.

Also I don't think is necessarily art/science split of the snow-type, or an artist/scientist division but that's besides the point. I just think there's a distinction between between the Prince-narcissism and the personality disorder called 'malignant narcissism.' As much as a Prince revels in himself or herself, there's also a separtion from the self by carefully creating an image, and maybe that's what the narcissist you're describing is doing. On the other hand, being beguiled by that image might be 'narcissistic,' but that might only be true if the narcissist confuses the difference.

Also, the person who displays what a psychologist would call narcissistic personality deisorder isn't necessarily concerned with anything of that nature. Or anything creative at all. As has been said in comments before mine, its (according to psychology) rooted in self-loathing and seems, to me, to have more to do with taking whatever the person wants, in excess, while devaluing anybody who gets in the way of this whatsoever. It seems closer to the spousal-abuser personality, with a huge appetite, and a shitty attitude extended to the entire world.
