Objectivism is terrific in a few ways. I still reread The Fountainhead once or twice a year. But the more you learn of it the shallower it becomes. The Fountainhead works because it's an incredibly contained world; Roark is essentially a loner. But Rand makes that out to be some ideal in and of itself. In truth, lots of brilliant people are radically social, and have had convoluted lives entirely unlike the straight path Roark takes. If you ignore that, and ignore the biological imperatives that explain it, then you're creating a fantastic type of human that doesn't really exist, and in some ways you belittle the people that Rand drew inspiration from to create Roark.
