To Craig: I am an atheist and I have meaning in life. You have stated that life is meaningless for the atheist. How can this be?
Craig: My statement is that life is objectively meaningless for the atheist. There is no ultimate purpose - we are all heading toward emptiness and death. You may hold to atheism and feel you have meaning in life, but you cannot point to some ultimate good that you accomplish, since all of reality will eventually die a heat death and there will be nothing more.
Hitchens: What gives meaning to my life is the fact that I am free of false beliefs. I have real liberty. Those "primates" who think they can tell me what to do on the basis of their beliefs. I am free of implausible beliefs. If you ask them really which world they care about, you will find it will be this one because they know this is the only real world there is.
