After having listened to a number of Rationally Selfish Webcast episodes, some passing statements make it sound like Ayn Rand had a complete understand and perfect execution of Objectivism. I'm attracted to Objectivism as a rational approach to morality and philosophy but bothered by how untouchable Ayn Rand appears to be. To compare Isaac Newton did wonders for the world of physics but if we hadn't evolved his theories our world today wouldn't be as advanced as it is today. Maybe a better question would be: What progress in understanding has been made by Objectivists since Rand's death?
