@de Silentio,
I just met Ragner Danneskjold for the first time, so no I'm about half way through. As somebody who has typically sympathized with the left, this book is opening some new perspectives.
You're right, it's a massive book and Ayn Rand is playing with a lot of issues. It's been hard to keep all of her positions straight but I realize that it's a work of fiction, not a philosophical treatise. Oh, and the fact that I'm only half way through (but it's been a swift read).
