I was half mad with beauty on that day...
~ William Morris, "The Defence of Guenevere"I've noticed that beautiful people, and people who create beautiful things, are often a little mad. (By "beautiful people," I mean people who have beautiful souls or minds, not attractive exteriors.) There's a sort of fragile beauty, the sort where you can hear the madness vibrating under the surface, like an impossibly light glass orb that might shatter if you touch it. It's the wildness of it, the thrill of unpredictability. It's the beauty of the endangered predator, the tiger that doesn't know it's one of the last of its kind, that can still kill you where you stand.
Madness itself can be beautiful, in its own way (hence the Gothic novel). There's a certain purity to madness, in that everything that affects a lunatic ultimately comes from within her own head (much of it is exhibited as response to stimuli, but the response is atypical -- i.e. not socially dictated). The greater part of the significance that literature assigns to madness is the uniqueness of its perspective.
Western culture idealizes individualism to an extent unmatched in other societies -- and that applies to Western intellectual culture as well. I think of it, sometimes, as the "genius in a box" phenomenon. People are attracted to the image of great ideas springing fully formed from the aether, like Athena from Zeus's head. They like thinking that geniuses are born, not made, and that they achieve their success purely through their own inscrutable methods. Of course, this construct doesn't quite reflect reality; as Newton once said, "If I have seen a little further it is by standing on the shoulders of giants." (His expression of the sentiment is the most famous, but not the first; the earliest known attribution is to Bernard of Chartres.) I actually just read, for a history of science class, an interesting book by Peter Galison entitled Einstein's Clocks, Poincaré's Maps, which argues (perhaps a tad overzealously) that Einstein, the quintessential representation of genius in modern Western culture, was inspired in the formation of his theories of relativity by the mathematician Henri Poincaré. One can't be a pioneer in one's field without having a good grasp of the work that preceded one's own. Genius is hardly ever as isolated as the romantic ideal would have it.
The thing is, genius is isolating only insofar as society renders it so. There were plenty of intellectuals throughout history who, in addition to being brilliant, were also scintillating conversationalists, consummate socialites and courtiers, and infamous Lotharios -- Renaissance men, as it were. It's terribly unfortunate that in the modern day, intelligence is seen as a social liability (that's probably a reflection on the state of American society, but we'll not go there tonight). But it's that isolation that makes it seem mysterious, unattainable -- and therefore beautiful.
A bit of a digression, I suppose. Perhaps not quite what Morris was going for, but that's how I read it.
