This week’s challenge is adapted from an objection sent by Doubting Eric:
You said that objective moral values are self-evidently true. How can we know this? Why would the fact that I intuit something to be true be considered evidence that it really is true? How would we be able to tell the difference between a truly objective moral value and a genetic adaptation that encourages moral behavior? They would both “feel” the same. You would “just know” that torturing babies for fun is wrong in the same way that you would if that was an objective moral truth. (The instinctual genetic origin of such a moral intuition or conscience could be easily demonstrated with examples from the wider animal kingdom.)
I don’t think we can tell the difference by our intuition. All we can really know is that WE PERSONALLY feel like this or that is the right thing to do. There is no reliable way of determining if there are moral values and duties that are actually objective.
Any ideas about how to respond to this one? Leave your thoughts below, then stick around for Thursday when we’ll hear Brett’s response.
