I agree with Dis. Any philosophy that leaves God out of the picture is flawed.
Coming up on prayer time. 3:15.
Join together to pray for our nation and each other.
When times are good, be happy; but when times are bad, consider: God has made the one as well as the other.
Ecc.7:14
I don’t see Rand’s philosophy as flawed as much as incomplete. She based the entire bedrock on the notion of 5 senses - objective reality. If you read Galt’s speech, there is nothing philosophically that can be refuted. It is all logically provable not unlike a geometric proof. And by proof I mean a series of arguments, starting from an original assumption and steps to show that a given assertion is true.
