I was raised Catholic, although I was never deeply religious. Now, many years later, a friend is showing me Ayn Rand's philosophy of Objectivism. I can see its benefits, but my religious upbringing still lingers in the back of my head. So part of me still thinks that God exists, even though I don't really believe that any longer. It was just engrained in me from such a young age that I can't seem to let it go. Can I change that? If so, how?
