Atlas shrugs, we the living and the Fountainhead all helped to shape who I am. I read them a zillion years ago and only recall certain small aspects about her philosophy. (A is A objectivism etc.)She was a brilliant mind and those who only get the atheistic part of it have missed much of her philosophy which is a slight variation of free market capitalism, IMHO.

Cheers!
