Well, I think Ayn Rand did a nice job of showing a line of atheism taken to its logical conclusion, and it was not communism. Remember, we are all born atheists.
Any Rands little fantasy left out one of the most critical if not the most critical component of man and that is his depravity.
Men are born in rebellion, if you have had children you know you did not have to teach them to do bad things and be selfish. You had to teach them to be “good”.
I’m assuming you have a conscience. What governs a man (or a lady)’s conscience?
BTW many professing “Christians” in the USA are themselves practical atheists, meaning in their every day practice they behave like atheists.
I would submit if there is no set standard of right and wrong, no absolute authority the logical end is communism, real communism with a very few absolute power and the rest treated as a number.
If you are a pure atheist what gives mankind dignity?
Since you cannot read my body language and demeanor on a electronic device I want you to know I’m not trying to belittle you I’m really curious as to your thoughts and appreciate the exchange of ideas.
