Skeptical of drinking from The Fountainhead

I'm researching Ayn Rand's novel, The Fountainhead. I read the voluminous work back in college, and found it preachy and philosophically disturbing. Rand uses the story to explain objectivism, which holds a radically autonomous view of the human person and proclaims the virtue of selfishness. Since college, I've talked to countless people who have were profoundly influenced by the novel, including Christians. I've struggled to articulate to them the intellectual discord between objectivism and Christianity, because, to some extent, Rand's philosophy describes human nature as we find it and, thus, resonates with reality. But this essay contrasting George Bailey with Rand's hero, Howard Roark, does the job well.
