Discussion: Is WLC’s Moral Argument Sound?

Today I’ll be hosting an exciting live discussion between Jeffery Jay Lowder and Wade Tisthammer on whether William Lane Craig’s moral argument (or one like it) is sound. William Lane Craig is known for giving a moral argument for God’s existence (see below). Jeff will be taking the position that it is not sound, while Wade will arguing that it is. Should be a really interesting exchange!

The discussion goes live at 3pm CST on Saturday, September 30, 2017. Here’s the link to view live (and watch later):

WLC’s Moral Argument

William Lane Craig’s version of the moral argument takes the following form:

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

(2) Objective moral values and duties exist.

(3) God exists.

The argument itself is logically valid. That is to say, if the premises are true, then the conclusion follows necessarily. Faulting the argument on the basis of logical invalidity is not an option.
