Naturalism, Theism, and Moral Ontology: A Reply to William Lane Craig

Abstract: This paper considers William Lane Craig’s metaethical argument for God’s existence. Roughly, the argument is that the existence of objective moral values provides strong evidence for God’s existence. I consider one by one Craig’s various reasons in support of the argument’s major premise, namely, that objective moral values and the nonexistence of God are at odds with each other. I show that Craig’s supporting arguments play fast and loose with the meaning of objectivity, and that they … [Read more...]

On Atheism and Brightness

I'm often told that atheists are really smart when it comes to religion. Then I read their replies to moral arguments for God's existence and cry out, "WTF?"Take this argument: If no G, then no O. But O. Therefore, G.Why the f&*^ would anyone think it's even relevant to bring up X, Y, or Z?!?!?Unlike some religious apologists, I don't believe the explanation is either (1) atheists are willfully repressing the truth of God's existence, or (2) atheists are stupid. Rather, my … [Read more...]

G&T Rebuttal, Part 6: Chapter 7

Metaethics

Chapter 7. Mother Theresa vs. Hitler  In this chapter, G&T present a version of the moral argument for God's existence which I call the "Moral Laws Require a Moral Lawgiver Argument," which they formulate as follows. 1. Every law has a law giver. 2. There is a Moral Law.3. Therefore, there is a Moral Law Giver. Like the earlier arguments, this argument is deductively valid. Like the earlier chapters about this argument, I plan to briefly summarize G&T's defense of … [Read more...]

Paul Copan’s Noseeum Argument Against Ethics Without God

Over the last fifteen or so years, Paul Copan has written a variety of articles, chapters, and books which argue against ethics without God. (To be precise, Copan argues against atheistic or naturalistic metaethics.) As I interpret him, Copan offers several independent arguments against ethics without God. I call one of those arguments "Copan's Noseeum Moral Argument" and that is the argument I want to discuss here.The basic idea of the argument is this. since we see no ontological … [Read more...]

An Incompatible-Properties Argument against Objective Values

In this post I want to sketch an argument against objective values (moral or otherwise).I shall first analyze the noun “value” and then the expression “moral value.” Finally, I will use these definitions to explicitly formulate an argument that objective values, so defined, have logically incompatible properties. In other words, the concept of an "objective value" is self-contradictory in the same way that "a married bachelor" or "a four-sided triangle" is self-contradictory.The Objecti … [Read more...]

More on the Arbitrariness Objection to the Divine Command Theory

I’ve been carrying on a conversation with Matthew Flannagan about the arbitrariness objection to the divine command theory. You can find my first post on the issue here and Matt’s response here. In this post I am going to continue my defense, against Flannagan’s objections, of the arbitrariness argument (AA):Either God’s commands are arbitrary or they are grounded in reasons. Arbitrary commands cannot ground moral obligations.  If God’s commands are grounded in reasons, then it is those … [Read more...]

Lewis, David Hume, and Bertrand Russell (Cambridge University Press, 2007).As you would expect … [Read more...]

Massimo Pigliucci on Metaethics, Part 1

William Lane Craig and Massimo Pigliucci debated the existence of God in 1998. (Click here to read the transcript.) In his opening statement, Craig presented his standard moral argument for God's existence. (1) If God does not exist, objective moral values do not exist. (2) Objective values do exist. (3) Therefore, God exists. In his opening statement, Pigliucci denied (2). Finally, the problem of morality, which I'm sure we'll have more to say about--oh yeah, I agree with Dr. Craig when he … [Read more...]
