As a Christian, it is interesting to note how intelligent Pollitt must think that she is since she (like Eve) arrogates to herself the prerogative to think that she can decide better than God when it comes to moral issues.
What is even more amazing is that she (and by implication you also, since you sent this e-mail), assumes some fixed standard of morality whereby Yahweh's laws as given in historical time can be weighed and judged over and against some moral standard that Yahweh has supposedly violated.
Since both you and she would take umbrage with the validity of the existence of Yahweh and His 10 commandments as given to the ancient Israelites , and assuming that you hold to one of the three major brands of atheistic materialism, I challenge you to answer the following questions:
(1) An Epistemological Question:
What non-arbitrary epistemological basis do you have to say that is it wrong for Yahweh not to forbid war, tyranny, invasion, slavery, exploitation of workers, cruelty to children, wife-beating, stoning and treating women like chattel since on the assumption of naturalistic materialism, you couldn't know it was wrong in the first place given the lack of reliability of your cognitive faculties?
In other words, assuming the truthfulness of your position, God doesn't exist and we are the products of naturalistic evolutionary theory. Given that proposition, consider what Charles Darwin had to say,
"With me, the horrid doubt always arises, whether the convictions of a man's mind, which have been developed from the minds of lower animals, are of any value or at all trustworthy. Why would anyone trust the convictions of a monkey's mind, if there were any convictions in such a mind?" [Darwin, C. 1881. Letter to W. Graham. In F. Darwin, ed., The Life and Letters of Charles Darwin. New York, D. Appleton & Co., 1905.]
Also, Richard Vitzhum, who wrote a definitive work titled 'Materialism: An Affirmative History and Definition' also commented in like manner,
And so, given naturalism and evolution, the probability that you have reliable cognitive faculties is low or inscrutable. This means you have a defeater for your belief that your cognitive faculties are reliably aimed at producing true beliefs (whatever "belief" is in your worldview).
On this assumption, atheistic materialist physicalist philosopher Patricia Churchland has also noted that given evolution, "truth, whatever that is, takes the hindmost." And, materialist Richard Rorty has noted that the belief that your beliefs are aimed at truth is "unDarwinian." (Now, you don't want to be "unDarwinian" do you?)
Worse yet, Darwin himself noted that he has "horrid doubt[s]" when he reflects on the assumption that his mind has evolved from the mind of lower animals. He rightly says that he wouldn't trust the convictions of a monkey's mind, and so assuming evolution and naturalism, why should he trust the convictions of his own mind?
And so, to sum it up, upon what epistemological basis can you know that moral realism exists (i.e., objective, absolute, universal, moral laws) assuming the conjunction of naturalism and evolution?
And to offer a related follow-up question: If what Pollitt says is true, how can you can figure out solutions to these perceived problems since the very cognitive faculties you use to problem solve are called into question by the very process they supposedly arose from?
(2) A Metaphysical Question:
Assuming Pollitt's argument is correct for the sake of argument, it would then follow that her argument against the supposed inferior nature of the decalogue is "true". But given the assumption of the truthfulness of that statement, how do you account for immaterial, abstract concepts of "truth" assuming only the existence of concrete particulars?
1. Concepts are immaterial.
2. But some versions of materialism (like yours) hold that anything that exists is material.
3. Our concepts are not material things.
4. Therefore, concepts do not exist.
5. Our concept of "truth" is immaterial.
6. In some versions of materialism (like yours), "truth" does not exist.
1. Material things are extended in space.
2. Our concept of "truth" is not extended in space.
3. Therefore, our concepts of "truth" are non-material.
4. Some versions of materialism (like yours) posit that no non-material entities exist.
5. Therefore, assuming some versions of materialism (like yours), concepts of "truth" do not exist.
Those questions should suffice for now. We'll see if your worldview has any money in its philosophical bank account to support the checks you are trying to write.
