We’re using the book “Handbook of Apologetics” by Peter Kreeft and Ronald Tacelli to go over the arguments for the existence of God. Dr. Kreeft teaches logic in two major universities, so his arguments tend to be clear, concise and very helpful.
Last week we looked at the Moral Argument. This week we’ll go over some questions it raises:
Question 1:
The argument has not shown that ethical subjectivism is false. What if there are no objective values?
Reply: True enough. The argument assumes that there are objective values; it aims to show that believing in them is incompatible with one picture of the world, and quite compatible with another. Those two pictures are the atheistic-materialistic one, and the (broadly speaking) religious one. Granted, if ethical subjectivism is true, then the argument does not work. However, almost no one is a consistent subjectivist. (Many think they are, and say they are—until they suffer violence or injustice.
In that case they invariably stand with the rest of us in recognizing that certain things ought never to be done.) And for the many who are not—and never will be—subjectivists, the argument can be most helpful. It can show them that to believe as they do in objective values is inconsistent with what they may also believe about the origin and destiny of the universe. If they move to correct the inconsistency, it will be a move toward the religious view and away from the atheistic one.
