Quoting from here:
Your question caught my eye, Jon, because I have been preparing for my debate with Alex Rosenberg, who describes himself as a “disenchanted naturalist.” He provides the following summary of atheism’s answers to some of life’s most persistent questions:
Is there a God? No.
What is the nature of reality? What physics says it is.
What is the purpose of the universe? There is none.
What is the meaning of life? Ditto.
Why am I here? Just dumb luck.
Is there a soul? Are you kidding?
Is there free will? Not a chance!
What is the difference between right/wrong, good/bad? There is no moral difference between them.
He concludes, “So much for the meaning of history, and everything else we care about.”
I agree with you that such a view of life is pretty unsatisfying. As Rosenberg says, if you’re going to be atheistic, “you will have to be comfortable with a certain amount of nihilism . . . . And just in case there’s always Prozac.”
