Ben Wallis’s counter-apologetics blog

Christian philosopher William Lane Craig has developed and defended an increasingly popular forumlation of the moral argument for the existence of God: (1) If God does not exist, objective moral values and duties do not exist. (2) Objective moral values and duties do exist. (3) Therefore, God exists. ( Reasonable Faith , p172.) His principal defense for premise (2) consists in pointing to our moral experience, where he thinks we apprehend the objectivity of morality. However I will argue that while there may be a semantic sense in which our moral experience does offer evidence for the objectivity of morality, nevertheless Craig has in mind a different, specialized sense of objectivity which involves the existence of a concrete exemplar, and which is unsupported by experience.

Recall that Joshua Rasmussen in his "New Argument for a Necessary Being" (2011), argues that (1) Normally, for any intrinsic property p that (i) can begin to be exemplified and (ii) can be exemplified by something that has a cause, there can be a cause of p's beginning to be exemplified. (p1) When I expressed concerns with his published defense of (1), he (first privately, and later publicly ) offered the following supplement (my paraphrase): Consider mundane intrinsic properties of the form being an apple , or being aluminum , etc., which can begin to be exemplified. Clearly such properties possibly have a cause for their exemplification, and so inductively we infer (1).
