Matt Dillahunty, David Baggett Discuss an Abductive Moral Argument

On Thursday, March 22, 2018 I’ll be hosting a new live discussion between Matt Dillahunty and David Baggett on the Abductive Moral Argument. We’ve had a few discussions on the moral argument already, but this one will be different. David, a professional philosopher and expert on the moral argument, thinks abductive versions are more promising than traditional deductive versions (like those proffered by William Lane Craig). For more, see the section below on Abductive Moral Arguments.

The discussion goes live at 8pm Central (6pm Pacific/9pm Eastern) on Thursday, March 22, 2018. Here’s the link to view live (and watch later):

An Abductive Moral Argument

William Lane Craig has made famous a deductive version of the moral argument. It goes like this:

(1) If God does not exist, objective moral values and duties do not exist.
(2) Objective moral values and duties exist.
(3) God exists.

This is a valid argument. That is to say, if the premises are true, the conclusion follows necessarily. The question is, are the premises true? Many philosophers and theologians have noted that (1) is actually a pretty strong claim and thus requires a significant line of defense. In essence, one must argue that there are no successful competing naturalistic theories. David Baggett contends there’s a better way of going about defending a moral argument.

Abductive versions of the argument seek to show that God is the best or most reasonable explanation of objective morality. Note, this doesn’t require annihilating every alternative, instead all that’s required is that God is the best or most reasonable alternative. Perhaps the naturalist has some moral theory that (for them) grounds moral realism. The abductivist can say, “Okay, that’s fine, but God better explains these various aspects of morality and so is still the better, more reasonable explanation.”

In the discussion, David will mention at least four aspects of morality he thinks God explains better than the alternatives. They are: moral facts (like objective moral values and duties), moral knowledge, moral transformation, and what David calls moral rationality.
