Update

I’ll be at the UW-Madison metaethics workshop this weekend. If you’re attending and what to meet up at some time, shoot me a message.

Also, I’m in the process of moving over to my own domain. I like some of the wordpress devkit tools and a friend hooked me up with some servage, so I just have to decide on a domain name and I’ll be gone from this particular site.

Naturalism Defeated? Chapter 1

William Ramsey is the first to offer a rebuttal to Plantinga’s EAAN. While the bulk of his response focuses on Plantinga’s interpretation of evolutionary epistemology, he begins by offering an externalist semantics where not only is the structure of our beliefs visible to natural selection, but the content of our beliefs is visible to natural selection. You’ll remember that Plantinga’s major step in this argument is the plausibility of semantic epiphenomenalism, where SE roughly means that the content of our beliefs rides on top of the structure. Most importantly, this means that a belief’s content doesn’t stand in a causal relation with the world in such a way that could make it visible to the mechanisms of contemporary evolutionary theory (whether or not genetic drift could is another question, and probably an implausible suggestion). Ramsey suggests, though, that the content of our beliefs is just as visible to natural selection as structure is, and illustrates this with a map analogy:

Suppose ten individuals are given ten different maps, only one of which provides an accurate route to buried treasure. If we want to explain the behavior of any given individual (including the one with the right map) then all we need to appeal to are the actual directions- the instructions and arrows and such- physically displayed on that individual’s map. The intrinsic features of the map are the causally relecant properties that produce the behavior in question, and the accuracy or inaccuracy of any given map would be, by and large, irrelevant. But now suppose that instead of explaining the actual behaviors of the treasure hunters, we want to know why the behavior of one hunter is of a certain sort- namely, of the sort that actually succeeds in finding the treasure. Clearly then it would be appropriate to appeal to the further fact that the lucky hunter’s map is the accurate one. That is, if we want to explain how one hunter actually manages to find the treasure, the accuracy of his map becomes the causally salient feature- it is what makes it the case that this particular hunter succeeds while the others fail. Indeed, if finding the treasure was in some way critical for survival, it would be the feature of the map that makes it the case that this hunter survives while others do not.
ND, p. 17.

So the content of a belief can supervene on, say, the structure of the world and our brain and the relation between them. Nevertheless, such an irreducible state such as being true can indeed be relevant with respect to explanation. So in the same sense that camouflage can be visible to natural selection (where the parts, like neurons, don’t explain it’s evolutionary worthiness), content is visible to natural selection. Essentially, I take Ramsey to simply deny Plantinga the possibility of his wedge between the structure and the content of belief. He is an externalist in the sense that beliefs aren’t in the brain, or rather, neuronal, but are relations that “reach out” and grab something in the outside world.

Ramsey’s second thrust of his essay is that Plantinga simply hasn’t provided a very good defeater for evolutionary reliabilism- the view that evolutionary processes shape our cognitive mechanisms. For one, it just seems prima facie unlikely that evolution could provide faculties that got things wrong most of the time while still proving adaptive. A point here that should probably be made clear is that Ramsey doesn’t think that evolution really selects beliefs. This is the wrong level of selection, and evolutionary forces select belief-forming mechanisms instead, which allows for error but, in a generalized analysis, tends to be conducive to truth. Without an account or explanation of those mechanisms (rather than ad hoc, highly complex Paul/tiger cases), it seems that Plantinga’s point is much weaker. Further, if we generalize Paul’s behavior with the tiger and make inferences to his belief-forming capacities, then it is a clear maladaption. Over time, his belief- or rather, the cognitive structure that produces such a belief- that petting tigers will prove destructive to his fitness.

Lastly, Ramsey goes on the offensive. Everyone realizes that there are mistakes in our inferential systems. Evolutionary reliabilism has a simple account for why this is so. But can theism provide such an account?

Ling and Lee on their adventures in Crazyland (N Korea)

Whether you buy their story or not- and with the nuts level of the North Koreans pegged at ‘High’, it seems likely to be true- it’s interesting. I wish they would divulge the details of their actual detainment conditions, but they’re probably saving it for a multi-million dollar book deal.

Naturalism Defeated?

During my free time this semester, I will be working on a project that I hope will be turned into a paper and/or presentation. I have an interest in Plantinga’s Evolutionary Argument Against Naturalism, and for the past few years I’ve been reading up on different sub-debates within that particular discussion. This argument is a bit unwieldy in it’s current form, lacking precise and persuasive premises (where persuasive means something like ‘reasonable for a large portion of the philosophical community’). The gist of the argument might be summed up as follows:

“The conjunction evolution and naturalism leaves the existence of our purportedly rational cognitive faculties unexplained or very improbable.”

You can find full expositions of the argument all over the internet, and I have no intention of adding another string of bits to the collection. Instead, if you are relatively unfamiliar with the debate then I’ll just suggest you start with Plantinga himself (here is an interesting recent presentation). With that bit said, what I’ll be doing the next [months? years?] will be a kind of review of some of the major criticisms of the argument from the volume of essays devoted to it (amz) entitled Naturalism Defeated? I have notes done on the first chapter and I’ll probably upload them piecemeal over the next week.

Sweet tubular clouds

Check this out:

I’ve never seen any clouds that look anything like that, and I’ve never seen any pictures of any clouds that look like that. Sweeeeeeet.

John Piper, heh

Christians are enamored with this guy?

The tornado in Minneapolis was a gentle but firm warning to the ELCA and all of us: Turn from the approval of sin. Turn from the promotion of behaviors that lead to destruction. Reaffirm the great Lutheran heritage of allegiance to the truth and authority of Scripture. Turn back from distorting the grace of God into sensuality. Rejoice in the pardon of the cross of Christ and its power to transform left and right wing sinners.

Where do I remember this kind of crazy-talk from…


Whoring out Jesus to the State

Jim Wallis is a partisan piece of shit. I don’t play these political games that he and his little cadre do, but I especially don’t play those games “in the name of Jesus”. Christians need to abandon Wallis and co. to the trash heap. It’s only fitting that he spews his vitriol on the Ed Show.

Should England apologize to Alan Turing?

So this story has been circulating for the past few days now:

Now Turing enthusiasts, led by John Graham-Cumming, are petitioning the government to make a formal apology for the treatment of Alan Turing. They say this would give a national recognition to the Turing’s remarkable contributions and would acknowledge the tragic consequences of a life and dazzling career cut short by prejudice.

So first the govt. forces sterilization on the man, and now it wishes to gain political points by “apologizing” to him? In what sense of the word is this “apology” meaningful? I say, to hell with British leeches (is there any other kind of political force?). Alan Turing will be remembered for his accomplishments for years after England dissipates. Great men transcend the barbaric political rituals of the earthly, temporal regimes.

An atheist tries to refute the Argument from Reason

Here is an example of missing the point:

Even though the argument from reason may sound good, the argument is a good example of begging the question (I.E. circular reasoning). The premise (that physical sources cannot constitute a rational source) is the conclusion (That naturalism – which says physical sources can constitute a rational source – is wrong). The reason that this is hard to see initially is due to the way in which the argument is laid out.

I think this is flatly incorrect. Saying that physical causes cannot be rational is not the same as saying naturalism is false. I think it gives a good reason to reject naturalism, but it might turn out that we are not rational and naturalism is true.

The central point of the argument is that merely physical sources cannot constitute a rational source, and therefore Lewis (and others) come to the conclusion that naturalism is self-refuting. Yet this premise is left without a proper explanation, and I don’t see why merely physical sources cannot constitute a rational source – in fact, this is one of the things that naturalism argues – that rationality can arise out of a purely physical source. A person employing the Argument from Rationality simply posits as a premise that it cannot, and then claims that this makes naturalism self-refuting. Obviously, we could refute nearly any worldview in this manner. Similarly, we could claim that any abstraction – from love to opinions to ideas to art – cannot arise out of purely physical sources and our argument would be no different. Why abstractions cannot arise out of physical sources is not explained, and I think they clearly can. It’s easy to create an imaginary solution to an imaginary problem.

No, this is a clear case of missing the point. We know that at a fundamental level physical causes don’t act for reasons. The reason an asteroid hits the Earth isn’t because it thinks colliding with our planet is the best way to achieve some end. It is acting in accordance with the laws of physics, and these laws (plus relevant physical conditions) comprehensively explains the event. So we have a prima facie case against the physical constitution of rationality. Is an emergent account possible? Perhaps. Is such an account forthcoming? Doubtful. Therefore the argument constitutes a good reason to reject naturalism.

Sophistry is a joy!

Indeed.
