I disagree or am uncomfortable with some of what Ayn Rand has to say, but everything she says is fascinating and worth listening to. She - perhaps more than any modern thinker - pushes us to seriously question the most basic assumptions upon which we have built and perpetuate our society. Even if you disagree with everything, it will never do you harm to listen to people who think differently from yourself and to consider why it is that you think and believe differently from them.
