Ayn Rand

I am reading Atlas Shrugged. Currently I'm in the middle of the 60 page monologue. In many ways it appeals to me; then I glimpse the uglier side of Rand's libertarian utopia, and I am shocked and somehow disappointed. I think that's her mistake. She denies original sin and assumes that some sort of utopia can be attained through libertarian capitalism on the basis of reason. But what is the reason based on? Ultimately it must be subjective. I love her picture of a man unhampered by guilt, seeking and finding joy in truly living, but I can't accept her premise. And I wonder, if she truly understood justification and the radical freedom from guilt found in Christ, would her view of Christianity have been any different? I feel suspended in the antithesis between her morality of the hero and that of the servant she despises.
