You: That is true, but I can't see how it makes any difference to my argument.

Aaron: It is an inner knowledge of God which allows one to identify that which is truly good.

You: Let's assume, for a moment that you are correct. What if the God that I have an inner knowledge of doesn't exist? Couldn't I still use him as my goodness ruler?

Aaron: How could you possibly use a non-existent thing in any way? If something does not exist, it does not exist.

You: Are you going to argue that the perfect sunset exists because I could not judge sunsets without it? How about the perfect woman? The perfect ear of corn?

Aaron: You are losing sight of my point. Even if you were able to say that a thing is good or bad without God — and I'm not ready to agree that that is truly possible — I must insist that there would be no good in the world without God's example. Man is lost without God's guidance.

You: I have done very well, thank you. Shall we change the subject before you get any more personal?

Aaron: Very well.
