Christian Apologists Ignore the Best Objections to the Moral Argument

To be precise, there are many kinds of moral arguments for theism. The question in the title is really talking about what we might call "ontological" or "metaphysical" moral arguments, the kind which claim that we need God in order to have an "ontological foundation" for objective or absolute morality.People who defend a version of this kind of argument include a veritable "Who's Who?" of contemporary Christian apologists: C.S. Lewis (see here and here), Alvin Plantinga (see here and here), W … [Read more...]

Can Atheism Support Ethical Absolutes? A Reply to Roger Olson

Roger Olson, a fellow Patheos blogger who can be found in the Evangelical channel on Patheos, has recently written a post entitled, "Can Atheism Support Ethical Absolutes? Is Ethics without Absolutes Enough?" In that post, he appeals to what has been called "Karamazov's Thesis," which is the claim (attributed to Dostoyevsky), that "If God does not exist, then everything is permitted."For readers who are interested in academic refutations of Karamazov's thesis, see refutations by Christian p … [Read more...]

Why I am Not Concerned about Christian Theist Philosophers of Religion

One reason I am not concerned about the prevalence of Christian theists in the field of philosophy of religion is that they do a nice job of arguing against each other.William Lane Craig's favorite argument for the existence of God is the Kalam cosmological argument. I'm happy that there are some atheist philosophers who challenge this argument, but there are good objections raised against this argument by Christian theist philosophers.For example, Richard Swinburne rejects this … [Read more...]

Hard-Hitting Critique of WLC’s Moral Argument by John Danaher “Necessary Moral Truths and Theistic Metaethics”

To be precise, this paper applies to WLC's moral argument for God's existence as follows.1. WLC argues that God exists because objective moral values and duties exist.2. Critics (theist, agnostic, and atheist) of WLC's moral argument have pointed out that, according to one version of moral realism, moral truths are necessary truths. Necessary truths neither have nor need an explanation. Therefore, God isn't needed to explain necessary moral truths and, hence, isn't needed to explain o … [Read more...]

Does Evolution “Explain” Objective Morality? A Reply to Jerry Coyne

Evolutionary biologist Jerry Coyne recently wrote about Leah Libresco's conversion from atheism to Catholicism based on a moral argument for God's existence. In his article, Coyne promotes the idea, which he has done many times before, that biological evolution somehow "explains" objective morality. While there is a sense in which Coyne is correct, that has nothing whatsoever to do with the kind of moral argument which Libresco finds persuasive. So while I join Coyne in rejecting Libresco's … [Read more...]

Amoral Atheism Part 2

Physics cannot justify why anything is morally right or wrong. No one says that is a defect of physics because that's not what physics is about.Like physics, atheism is also not about morality. So why should it be a defect of atheism that it cannot justify why anything is morally right or wrong? … [Read more...]

Are Norm Geisler and Frank Turek Dishonest?

Those of you have been following my writing for years know that I am very cautious about questioning another person's integrity. (If you're not familiar with, do a search on Jeff Lowder, William Lane Craig, and dishonesty or lying.) But this time I have stumbled across something so egregious I am having a very hard time coming up with a charitable explanation. In their book, I Don't Have Enough Faith to be an Atheist, Christian apologists Norman Geisler and Frank Turek write the following about t … [Read more...]

An F-Inductive Moral Argument for Theism

Here is an F-inductive argument for theism based on ontologically objective moral values. Note that this argument assumes that such things exist. If you don't think they exist, then you may want to skip reading this post.As usual, let B be our background information; E be the evidence to be explained (in this case, the existence of ontologically objective moral values); T be theism; and N be naturalism. Here is the explanatory argument.1. E is known to be true, i.e., Pr(E) is close to 1. … [Read more...]
