A Summary of My Paper

By R.N. Carmona

I have submitted a paper to Philosophical Studies addressing Dustin Crummett and Philip Swenson’s paper. Admittedly, this is my first attempt at publishing in a philosophy journal. I took a swing with no guidance, no co-author, and no funding. There is of course a chance it gets rejected, but I am hoping for the best. In any case, I think my paper provides heuristics for anyone looking to refute Evolutionary Moral Debunking Arguments like Crummet and Swenson’s. Let us turn to how I dissect their argument.

They claim that their Evolutionary Moral Debunking Argument Against Naturalism (EMDAAN) stems from Street’s and Korman and Locke’s EMDAs. The latter EMDAs target moral realism while Crummett and Swenson’s targets naturalism. The issue with theirs is that they grossly overlook the fact that both Street and Korman & Locke do not argue that naturalism is threatened by EMDAs. Street argues that her practical standpoint characterization of constructivism sidesteps any issues her EMDA might have presented for her naturalism. Korman and Locke target the minimalist response and in a separate paper, not cited by Crummett, relativism. They do not target naturalism either.

At first glance, I compared Crummett and Swenson’s argument to Lewis’ long-defeated Argument Against Atheism. They state: “The problem for the naturalist here is that, if naturalism is true, it seems that the faculties responsible for our intuitions were formed through purely natural processes that didn’t aim at producing true beliefs” (Crummett & Swenson, 37). One can easily see how they paraphrase Lewis who says:

Supposing there was no intelligence behind the universe, no creative mind. In that case, nobody designed my brain for the purpose of thinking. It is merely that when the atoms inside my skull happen, for physical or chemical reasons, to arrange themselves in a certain way, this gives me, as a by-product, the sensation I call thought. But, if so, how can I trust my own thinking to be true? It’s like upsetting a milk jug and hoping that the way it splashes itself will give you a map of London. But if I can’t trust my own thinking, of course I can’t trust the arguments leading to Atheism, and therefore have no reason to be an Atheist, or anything else. Unless I believe in God, I cannot believe in thought: so I can never use thought to disbelieve in God.

This is a known predecessor of Plantinga’s Evolutionary Argument Against Naturalism (EAAN). Therefore, the first angle I take in the paper is to show how Crummett and Swenson did not understand Street’s paper. Perhaps it is the sheer length of her excellent paper (over 50 pages) or perhaps they were so intent on addressing New Atheists that they overlooked her more robust approach to showing how anti-realism fares against EMDAs. I think her paper makes a lot more sense when read in conjunction with her overview of constructivism (see here). Bearing that in mind, I attempt to divorce Crummet and Swenson’s EMDAAN from Street’s EMDA against moral realism. Korman and Locke’s project is markedly different, but their work does not help Crummett and Swenson’s argument either.

With the EAAN now in focus, I show how Crummett and Swenson’s EMDAAN just is an iteration of the EAAN. The EAAN applies to general truths. Put simply, Plantinga argues that if we take seriously the low probability of evolution and naturalism being true despite the fact that that our cognitive faculties formed from accidental evolutionary pressures, then we have a defeater for all of our beliefs, most notably among them, naturalism. Crummett and Swenson make the same exact argument, the difference being that they apply it to specific beliefs, moral beliefs. Given that moral beliefs are a sub-category within the domain of all beliefs, their EMDAAN is an iteration of the EAAN. Here is an example I did not pursue in my paper, call it the Evolutionary Scientific Debunking Argument.

RC1 P(Sm/E&S)  is low (The probability that our faculties generate basic scientific beliefs, given that evolution and science are true, is low.)

RC2 If one accepts that P(Sm/E&S) is low, then one possesses a defeater for the notion that our faculties generate basic scientific beliefs.

RCC Therefore, one possesses a defeater for one’s belief in science.

Perhaps I would be called upon to specify a philosophical view of science, be it realism or something else, but the basic gist is the same as Crummett and Swenson’s EMDA. I am, like them, targeting a specific area of our beliefs, namely our beliefs resulting from science. My argument is still in the vein of Plantinga’s EAAN and is a mere subsidiary of it.

After I establish the genealogy of Crummett and Swenson’s argument, I turn the EAAN on its head and offer an Evolutionary Argument Against Theism. If Plantinga’s argument holds sway and the Theist believes that evolution is true, he is in no better epistemic shape than the naturalist. Therefore, Plantinga’s conditionalization problem, which offers that P(R/N&E) is high iff there exists a belief B that conditionalizes on N&E, is an issue for Theists as well. In other words, perhaps the probability that our cognitive faculties are reliable given that evolution and naturalism are true increases iff there is an added clause in the conjunction. Put another way, the probability that our cognitive faculties are reliable, granting that evolution and naturalism and (a successful philosophy of mind), is high. This successful philosophy of mind will have to show precisely how a brain that resulted from naturalistic evolutionary processes can generate the sort of consciousness capable of acquiring true beliefs. The theist who says P(R/T&E) is high is begging the question because merely asserting that “God ensured that there would be some degree of alignment between our intuitions and moral truth” ((Crummett & Swenson, 44) does not help the Theist avoid the conditionalization problem.

With that established, and I cannot give too much away here because this is the novelty in my paper, I argue that the only recourse the Theist has, especially given that they have no intention of disavowing Theism, is to abandon their belief in evolution. They would have to opt, instead, for a belief in creationism or a close variant like intelligent design. In either case, they would then be left asserting that a Creationary Moral Confirming Argument in Favor of Theism is the case. I explore the litany of issues that arises if the Theist abandons evolution and claims that God’s act of creating us makes moral realism the case. Again, the Theist ends up between a rock and a hard place. Theism simply has far less explanatory power because, unlike naturalism, it does not account for our propensity to make evaluative errors and our inclination toward moral deviancy. If God did, in fact, ensure that our moral intuitions align with transcendent moral truths, why do we commit errors when making moral decisions and why do we behave immorally? Naturalism can explain both of these problems, especially given the role of reason under the moral anti-realist paradigm. Evaluative errors are therefore, necessary to improve our evaluative judgments; reason is the engine by which we identify these errors and improve our moral outlook. The Theist would be back at square one, perhaps deploying the patently mythical idea of a Fall to account for the fact that humans are far from embodying the moral perfection God is said to have.

With Crummett and Swenson’s argument now thoroughly in Plantinga’s territory, I explore whether the anti-realist can solve the conditionalization problem. I suggest that evolution accounts for moral rudiments and then introduce the notion that cultural evolution accounts for reliable moral beliefs. Cooperation and altruism feature heavily into why I draw this conclusion. So P(Rm/E&MAR) (if evolution and moral anti-realism are true, the probability that our faculties generate evaluative truths) is high given that cooperation and/or altruism conditionalize on our belief that evolution and moral anti-realism are the case. We are left with P[(Rm/E&MAR) & (C v A)] or P[(Rm/E&MAR) & (C&A)]. In other words, if evolution and moral anti-realism are true, and cooperation and/or altruism conditionalize on our beliefs that evolution and moral anti-realism are the case, the probability that our faculties generate evaluative truths/reliable moral beliefs is high.

Ultimately, like Moon, I think my paper will provide fertile ground for further discussion on the conditionalization problem. The jury is still out on whether the naturalist’s belief that evolution and naturalism are true even requires a clause to conditionalize on that belief. In any case, much can be learned about EMDAs against naturalism from the vast literature discussing Plantinga’s EAAN. I think that my arguments go a long way in dispensing with EMDAs in the philosophy of religion that target naturalism. When one considers that the Theist cannot account for moral truths without unsubstantiated assertions about God, it is easy to see how they are on less secure ground than the naturalist. If the Theist is a Christian or a Muslim, then they ought to be reminded that their scriptures communicate things about their gods that are not befitting of moral perfection. If the choice is between naturalism and the belief that a god who made parents eat their children is, despite all evidence to the contrary, morally perfect, I will take my chances with naturalism!

      Not much to go on given just the abstract, but I have expressed issues with necessitism before, and will add here that occasionalism is incompatible with Christian Theism. There is also the issue of a timeless god occasionally interfering with a temporal domain. Naturalists are owed a causal principle that allows an immaterial being to influence material objects. Those are just first impressions from what I can gather from the abstract. I would need to read the paper.

      Ultimately, the reason I side with Nielsen, Keith Augustine, Parsons, and others with respect to moving on from these Christian-centric arguments for Theism is because, by simple induction and in light of Theism’s track record, if the vast number of arguments they came up with failed, it is reasonable to hold that current and future arguments will also fail; if Christian Theism is a bag of beans and all the beans thus far have been spoiled, do I have any obligation to check the rest? It really is telling that so many Christian Theists have pretty much abandoned the evidentialist post and are now retreating to fideist, existentialist, and modalist posts. The former two are easily addressed. Whether Kierkegaard or someone like David Bentley Hart, a sort of Christian existentialism or even humanism doesn’t do much to move their case in the right direction.

      In any case, I don’t know if I will get around to addressing this particular argument. I have my plate full with a number of other things at the moment. Time will tell. When and if I do though, I’ll be sure to circle back and let you know! If you have a link to the actual paper, please share and I’ll archive it for a later time.
