Another lottery tragedy

From CNN:
A Florida woman has been charged with first-degree murder in connection with the death of a lottery millionaire whose body was found buried under fresh concrete, authorities said.

Dorice Donegan Moore, 37, was arrested last week on charges of accessory after the fact regarding a first-degree murder in the death of Abraham Shakespeare, 43, said Hillsborough County Sheriff David Gee. She remains in the Hillsborough County Jail, he said.

Moore befriended Shakespeare after he won a $31 million Florida lottery prize in 2006 and was named a person of interest in the case after Shakespeare disappeared, authorities said.

Where is the global climate model without AGW?

One of the regular critics of creationism on the Usenet talk.origins newsgroup (where the wonderful Talk Origins Archive FAQs were originally developed) was a guy who posted under the name "Dr. Pepper." His posts would always include the same request--"Please state the scientific theory of creationism." It was a request that was rarely responded to, and never adequately answered, because there is no scientific theory of creationism.

A parallel question for those who are skeptical about anthropogenic climate change is to ask for a global climate model that more accurately reflects temperature changes over the last century than those used by the IPCC, without including the effect of human emissions of greenhouse gases. For comparison, here's a review of the 23 models which contributed to the IPCC AR4 assessment. While these models are clearly not perfect, shouldn't those who deny anthropogenic global warming be able to do better?

A few comments on the nature and scope of skepticism

Of late there has been a lot of debate about the nature, scope, and role of skepticism. Does skepticism imply atheism? Are "climate change skeptics" skeptics? Must skeptics defer to scientific consensus or experts? Should skepticism as a movement or skeptical organizations restrict themselves to paranormal claims, or avoid religious or political claims?

I think "skepticism" can refer to multiple different things, and my answers to the above questions differ in some cases depending on how the term is being used. It can refer to philosophical skepticism, to scientific skepticism, to "skeptical inquiry," to "doubt" broadly speaking, to the "skeptical movement," to skeptical organizations, and to members of the class of people who identify themselves as skeptics.

My quick answers to the above questions, then, are:

Does skepticism imply atheism? No, regardless of which definition you choose. It is reasonable to argue that proper application of philosophical skepticism should lead to atheism, and to argue that scientific skepticism should include methodological naturalism, but I prefer to identify skepticism with a commitment to a methodology rather than its outputs. That still involves a set of beliefs--which are themselves subject to reflection, criticism, and evaluation--but it is both a more minimal set than the outputs of skepticism and involves commitment to values as well as what is scientifically testable. My main opposition to defining skepticism by its outputs is that that is a set of beliefs that can change over time with access to new and better information, and shouldn't be held dogmatically.

Are "climate change skeptics" skeptics? I would say that some are, and some aren't--some are outright "deniers" who are allowing ideology to trump science and failing to dig into the evidence. Others are digging into the evidence and just coming to (in my opinion) erroneous conclusions, but that doesn't preclude them from being skeptics so long as they're still willing to engage and look at contrary evidence, as well as admit to mistakes and errors when they make them--like relying on organizations and individuals who are demonstrably not reliable. As you'll see below, I agree we should to try to save the term "skeptic" from being equated with denial.

Must skeptics defer to scientific consensus or experts? I think skeptical organizations and their leaders should defer to experts on topics outside of their own fields of expertise on pragmatic and ethical grounds, but individual skeptics need not necessarily do so.

Should skepticism as a movement or skeptical organizations restrict themselves to paranormal claims, or avoid religious or political claims? I think skepticism as a movement, broadly speaking, is centered on organizations that promote scientific skepticism and focus on paranormal claims, but also promote science and critical thinking, including with some overlap with religious and public policy claims, where the scientific evidence is relevant. At its fringes, though, it also includes some atheist and rationalist groups that take a broader view of skeptical inquiry. I think those central groups (like CSI, JREF, and the Skeptics Society) should keep their focus, but not as narrowly as Daniel Loxton suggests in his "Where Do We Go From Here?" (PDF) essay.

Here are a few of my comments, on these same topics, from other blogs.

Comment
on Michael De Dora, "Why Skeptics Should be Atheists," at the Gotham Skeptic blog:

Scientific skepticism (as opposed to philosophical skepticism) no more necessitates atheism than it does amoralism. Your argument would seem to suggest that skeptics shouldn’t hold any positions that can’t be established by empirical science, which would seem to limit skeptics to descriptive, rather than normative, positions on morality and basic (as opposed to instrumental) values.

“Skepticism” does have the sort of inherent ambiguity that “science” does, in that it can refer to process, product, or institution. I favor a methodological view of skepticism as a process, rather than defining it by its outputs. Organizations, however, seem to coalesce around sets of agreed-upon beliefs that are outputs of methodology, not just beliefs about appropriate/effective methodology; historically that set of agreed-upon beliefs has been that there is no good scientific support for paranormal and fringe science claims. As the scope of skeptical inquiry that skeptical organizations address has broadened, that leads to more conflict over issues in the sphere of politics and religion, where empirical science yields less conclusive results.

I’d rather see skeptical organizations share some basic epistemic and ethical values that are supportive of the use of science than a commitment to a set of beliefs about the outputs of skeptical methodology. The latter seems more likely to result in dogmatism.

Comment on Daniel Loxton, "What, If Anything, Can Skeptics Say About Science?" at SkepticBlog:

While I think the picture Daniel presents offers some good heuristics, I can’t help but note that this is really proffered normative advice about the proper relationship between the layman and the expert, which is a question that is itself a subject of research in multiple domains of expertise including philosophy of science, science and technology studies, and the law. A picture much like the one argued for here is defended by some, such as philosopher John Hardwig (”Epistemic Dependence,” Journal of Philosophy 82(1985):335-349), but criticized by others, such as philosopher Don Ihde (”Why Not Science Critics?”, International Studies in Philosophy 29(1997):45-54). There are epistemological, ethical, and political issues regarding deference to experts that are sidestepped by the above discussion. Not only is there a possibility of meta-expertise about evaluating experts, there are cases of what Harry Collins and Robert Evans call “interactional expertise” (”The Third Wave of Science Studies: Studies of Expertise and Experience,” Social Studies of Science 32:2(2002):235-196) where non-certified experts attain sufficient knowledge to interact at a deep level with certified experts, and challenge their practices and results (this is discussed in Evan Selanger and John Mix, “On Interactional Expertise: Pragmatic and Ontological Considerations,” Phenomenology and the Cognitive Sciences 3:2(2004):145-163); Steven Epstein’s book Impure Science: AIDS, Activism, and the Politics of Knowledge, 1996, Berkeley: Univ. of California Press, discusses how AIDS activists developed such expertise and successfully made changes to AIDS drug research and approval processes.

The above discussion also doesn’t discuss context–are these proposed normative rules for skeptics in any circumstance, or only for those speaking on behalf of skeptical organizations? I don’t think it’s reasonable to suggest that skeptics, speaking for themselves, should be limited about questioning anything. The legal system is an example of a case where experts should be challenged and questioned–it’s a responsibility of the judge, under both the Frye and Daubert rules, to make judgments about the relevance and admissibility of expert testimony, and of laymen on the jury to decide who is more credible. (This itself raises enormous issues, which are discussed at some length by philosopher and law professor Scott Brewer, “Scientific Expert Testimony and Intellectual Due Process,” The Yale Law Journal vol. 107, 1535-1681.) Similar considerations apply to the realm of politics in a democratic society (cf. Ihde’s article).

All of the papers I’ve cited are reprinted in the volume The Philosophy of Expertise, edited by Evan Selinger and Robert P. Crease, 2006, N.Y.: Columbia University Press.

Comment on jdc325's "The Trouble With Skeptics" at the Stuff And Nonsense blog:
@AndyD I’d say that it’s possible for a skeptic to believe individual items on your list (though not the ones phrased like “the entirety of CAM”), so long as they do so because they have legitimately studied them in some depth and think that the weight of the scientific evidence supports them, or if they admit that it’s something they buy into irrationally, perhaps for the entertainment it brings or to be part of a social group. If, however, they believe in a whole bunch of such things, that’s probably evidence that they’re not quite getting the point of critical thinking and skepticism somewhere. Being a skeptic doesn’t mean that you’re always correct (as per the above comment on Skeptic Fail #7), and I don’t think it necessarily means you’re always in accord with mainstream science, either.

Skeptic fail #6 is a pretty common one. For example, I don’t think most skeptics have a sufficient knowledge of the parapsychology literature to offer a qualified opinion, as opposed to simply repeat the positions of some of the few skeptics (like Ray Hyman and Susan Blackmore) who do.
Comments (one and two) on "Open Thread #17" at Tamino's Open Mind blog:

Ray Ladbury: I think you’re in a similar position as those who want to preserve “hacker” for those who aren’t engaged in criminal activity. I understand and appreciate the sentiment, but I think “skeptic” already has (and, unlike “hacker,” has actually always had) common currency in a much broader sense as one who doubts, for whatever reason.

I also think that there are many skeptics involved in the organized and disorganized skeptical movement in the U.S. (the one started by CSICOP) who don’t meet your criteria of “sufficiently knowledgeable about the evidence and theory to render an educated opinion” even with respect to many paranormal and pseudoscience claims, let alone with respect to climate science. There’s an unfortunately large subset of “skeptics” in the CSICOP/JREF/Skeptics Society sense who are also climate change skeptics or deniers, as can be seen from the comments on James Randi’s brief-but-retracted semi-endorsement of the Oregon Petition Project at the JREF Swift Blog and on the posts about climate science at SkepticBlog.org.

Ray: You make a persuasive argument for attempting to preserve “skeptic.” Since I’ve just been defending against the colloquial misuse of “begs the question,” I think I can likewise endorse a defense of “skeptic” against “pseudoskeptic.” However, I think I will continue to be about as reserved in my use of “denier” as I am in my use of “liar.” I don’t make accusations of lying unless I have evidence not just that a person is uttering falsehoods, but that they’ve been presented with good evidence that they are uttering falsehoods, and continue to do so anyway.

On another subject, I’d love to see an equivalent of the Talk Origins Archive (http://www.talkorigins.org/), and in particular Mark Isaak’s “Index to Creationist Claims” (http://www.talkorigins.org/indexcc/list.html) for climate science (and its denial). Do they already exist?

Some previous posts at this blog on this subject may be found under the "skepticism" label, including:

"Massimo Pigliucci on the scope of skeptical inquiry"
(October 21, 2009)
"Skepticism, belief revision, and science" (October 21, 2009)

Also, back in 1993 I wrote a post to the sci.skeptic Usenet group that gave a somewhat oversimplified view of "the proper role of skeptical organizations" which was subsequently summarized in Michael Epstein's "The Skeptical Viewpoint," Journal of Scientific Exploration, vol. 7, no. 3, Fall 1993, pp. 311-315.

UPDATE (January 7, 2010): Skepdude has taken issue with a couple of points above, and offers his contrary arguments at his blog. First, he says that skeptics need to defer to scientific consensus with the "possible exception" of cases where "the person is also an expert on said field." I think that case is a definite, rather than a possible exception, but would go farther--it's possible to be an expert (or even just a well-informed amateur) in a field that has direct bearing on premises or inferences used by experts in another field where one is not expert. That can give a foothold for challenging a consensus in a field where one is not expert. For example, philosophers, mathematicians, and statisticians can spot errors of conceptual confusion, fallacious reasoning, invalid inferences, mathematical errors, and misuse of statistics. It's possible for an entire field to have an erroneous consensus, such as that rocks cannot fall from the sky or continents cannot move. I suspect an argument can be made that erroneous consensus is more likely to occur in a field with a high degree of specialization that doesn't have good input from generalists and related fields.

I also am uncomfortable with talk of "deference" to experts without scope or context, as it can be taken to imply the illegitimacy of questioning or demanding evidence and explanation in support of the consensus, which to my mind should always be legitimate.

The second point is one which Skepdude and I have gone back and forth on before, both at his blog (here, here, and here -- I could have used these comments as well in the above post) and via Twitter, which is about whether skepticism implies (or inevitably leads) to atheism. It's a position which I addressed above in my comments on Michael De Dora and on the "Stuff and Nonsense" blog, though he doesn't directly respond to those. He writes:
I fail to see the distinction between skepticism implying atheism and proper application of skepticism leading to atheism. I regard the two as saying the same thing, that skepticism, if consistently applied should lead to atheism. I am not sure what Jim means by philosophical skepticism, and maybe that’s where he draws the difference, but I refrain from using qualifiers in front of the word skepticism, be it philosophical or scientific. Skepticism is skepticism, we evaluate if a given claim is supported by the evidence.
There is most definitely a distinction between "skepticism implies atheism" and "proper application of skepticism leads to atheism." The former is a logical claim that says atheism is derivable from skepticism, or that it's necessarily the case that the use of skepticism (regardless of inputs?) yields atheism. The latter is a contingent claim that's dependent upon the inputs and the result of the inquiry. If skepticism is defined as a method, the former claim would mean in essence that the game is rigged to produce a particular result for an existence claim necessarily, which would seem to me to be a serious flaw in the method, unless you thought that atheism was logically necessary. But I'm not aware of any atheists who hold that, and I know that Skepdude doesn't, since he prefers to define atheism as mere lack of belief and has argued that there is no case to be made for positive atheism/strong atheism.

If we take skepticism defined as a product, as a set of output beliefs, there's the question of which output beliefs we use. Some idealized set of beliefs that would be output from the application of skeptical processes? If so, based on which set of inputs? In what historical context? The sets of inputs, the methods, and the outputs all have changed over time, and there is also disagreement about what counts as appropriately well-established inputs and the scope of the methods. The advocate of scientific skepticism is going to place more constraints on what is available as input to the process and the scope of what the process can deal with (in such a way that the process cannot be used even to fully evaluate reasons for being a skeptic, which likely involve values and commitments that are axiomatic or a priori). Methodological naturalism is likely to be part of the definition of the process, which means that theism cannot be an output belief--I think this is probably what Skepdude means when he says that atheism defined as a lack of belief is a product of skepticism. But note that the set of output beliefs from this process is a subset of what it is reasonable to believe, unless the advocate of this view wants to assert that the commitment to skepticism itself is not reasonable to believe--in virtue of the fact that it is not subject to a complete evaluation by the process. (As an aside, I think that it is possible for the process of skepticism thus defined to yield a conclusion of its own inadequacy to address certain questions, and in fact, that if we were to observe certain things, to yield the conclusion that methodological naturalism should be rejected.)

If we look at skepticism more broadly, where philosophical arguments more generally are acceptable as input or method, atheism (in the positive or strong form) then becomes a possible output. As an atheist, I think that use of the best available evidence and arguments and the best available methodology does lead to a conclusion of atheism (and 69.7% of philosophy faculty and Ph.D.s agree), that still doesn't mean that everyone's going to get there (as 69.3% of philosophy faculty and Ph.D.s specializing in philosophy of religion don't) or that anyone who doesn't has necessarily done anything irrational in the process, but for a different reason than in the prior case. That reason is that we don't function by embodying this skeptical process, taking all of our input data, running it through the process, and believing only what comes out the other side. That's not consistent with how we engage in initial learning or can practically proceed in our daily lives. Rather, we have a vast web of beliefs that we accumulate over our lifetimes, and selectively focus our attention and use skeptical processes on subsets of our beliefs. The practical demands of our daily lives, of our professions, of our social communities, and so forth place constraints on us (see my answers to questions in "Skepticism, belief revision, and science"). And even with unlimited resources, I think there are reasons that we wouldn't want everyone to apply skeptical methods to everything they believed--there is value to false belief in generating new hypotheses, avoiding Type I errors, keeping true beliefs from becoming "dead dogma," and so forth (which I discussed in my SkeptiCamp Phoenix presentation last year, "Positive side-effects of misinformation").

UPDATE (January 16, 2009): Skepdude responds here.

Definitions of atheism and agnosticism

I recently posted this at the Phoenix Atheists Meetup group's discussion forum in a thread titled "atheism v. agnosticism," and thought it might be worth reposting here:

There are lots of ways to define these terms, to the extent that you can't be sure how people are using them unless you ask.

The general population of English speakers understands atheism to be equivalent to what Michael Martin calls "positive atheism" and what used to be commonly known among Internet atheists as "strong atheism"--an active disbelief in the existence of gods. That's a position which does have a burden of proof over mere nonbelief, also known as weak atheism or negative atheism. George H. Smith made the same distinction using the terms explicit vs. implicit atheism. Richard Dawkins complicated matters by redefining "strong atheism" as absolute certainty that there is no God (position 7 on his scale). I wish he had chosen a different term, as I think it's a mistake to associate positive atheism/strong atheism with certainty, proof, or even knowledge.

I used to like this distinction, but am less enamored with it because "weak atheism" or "negative atheism" or atheism as mere lack of belief in gods has a few logical problems as a basis for anything. A lack of belief is not a position, it cannot be used to motivate action or to infer conclusions from. Those who say that they are only atheists in the weak sense, however, do join groups and appear to draw inferences and conclusions as though they are using the nonexistence of gods as a premise, which means either that they are really implicitly using strong atheism as a position, or they are drawing those inferences based on other meta-beliefs.

The advantage of equating atheism with weak atheism is that theism and atheism then become contradictories which cover the entire space of logical possibilities--you either have a belief in one or more gods, or you don't. Under that definition, there's no space for agnosticism except as a subset of one or both of atheism and theism.

The definition of "agnosticism" that was given earlier in this thread as pertaining to the possibility of knowledge about the existence or nonexistence of gods then gives you two dimensions, on which you can have agnostic atheists (I don't believe there are gods, and it's not possible to know), agnostic theists (I believe in at least one god, but it's not possible to know), gnostic atheists (I don't believe there are gods, and it is possible to know there aren't), and gnostic theists (I believe there's at least one god, and it's possible to know). Of those positions, I think agnostic theism is difficult to make a case for with respect to most conceptions of God, except for deism and other forms of uninvolved gods.

But most people who call themselves agnostics aren't using that definition, they're using a notion that is a particular form of weak atheism, that holds to something like there is a parity between arguments for and against the existence of gods, or that there is no way to effectively compare their evidential weight, or similar. They might agree with agnosticism regarding the possibility of knowledge for the existence or nonexistence of gods, but they go further and say that there is some parity on the case for mere belief in either direction, as well.

I'm generally in favor of allowing people to choose their own self-identifying terms and defining them as they see fit, so long as they can give a legitimate reason for their classification and it's not completely at odds with ordinary usage. One example that goes beyond ordinary usage and I think just indicates some kind of confusion is that 21% of self-identified atheists in a Pew survey reported last October said that they believe in God. Sorry, but that's not a definition of atheist that I think can get off the ground.

My own position is strong atheism/positive atheism with respect to most traditional conceptions of God, and weak atheism/agnosticism (or igtheism) with respect to certain rarefied/unempirical notions of God. I'm comfortable calling myself an atheist in general, and dispute claims that it's impossible have knowledge that at least most gods do not exist. "You can't prove a negative" is a widely expressed canard, which I argue against here:

http://www.discord.org/~lippard/debiak.html

That also contains links to a few other essays which make the same point in a way that is probably more clear, including one by Jeff Lowder which argues for the possibility of disproofs of God's existence.

UPDATE (November 22, 2010): Also see the Internet Infidels' Atheist Web definition page.  I now suspect that "empirical agnosticism" and "weak atheism" are indistinguishable.

UPDATE (November 24, 2011): Also see Jeff Lowder's January 4, 2006 post at Naturalistic Atheism, "Disagreement Among Self-Described Atheists about the Meaning of 'Atheism'" and Ted Drange's 1998 article at the Secular Web, "Atheism, Agnosticism, and Noncognitivism." Drange's distinctions seem to me to be well worth using.  Maverick Philosopher's "Against Terminological Mischief: 'Negative Atheism' and 'Negative Nominalism'" is also good.

UPDATE (January 20, 2012): Jeff Lowder has written further on this subject at the Secular Outpost, in "The Definition of Atheism, the Anal-Retentive Defense of Etymological Purism, and Linguistic Relativism."

Sixth stay dog of 2009


We found this little dog, Max, while on our way to do a RESCUE volunteer shift, running around loose in a vacant lot near a school. He was very bedraggled and thirsty, and had apparently been loose for a while (days, at least). Fortunately, he had tags, so I left messages at the number on his personalized tag and at the different number associated with his county tag, which it's easy to look up at Pets911.com. An hour or two later, I got a call from the dog's previous owner (to whom the dog is still registered), who sent her husband out to pick him up. They didn't know what had happened to the current owner or why the dog was loose.

Vocab Malone on abortion and personhood, part 5

Vocab has put up the fifth and final part of his essay on abortion and personhood up at his blog, devoted to Thomson's violinist argument. I don't really have much to say about it--we didn't coordinate our posts in advance, and I've already discussed Thomson's argument myself in my response to part 4. I disagree with Vocab's claim that Thomson's argument proves too much and would allow infanticide--her argument only addresses a physically dependent fetus. And, as I already pointed out in my prior response, the argument doesn't prove as much as it purports to. The violinist case isn't exactly analogous to pregnancy and abortion in a number of ways, and Vocab is right to point out the differences. I agree that if a pregnancy is allowed to go to term (as well as to some earlier point at which there is plausible evidence for personhood on my standard), then that entails at least tacit consent and a moral duty of care. I would still argue, however, that abortion would be legitimate beyond that point for medically justifiable reasons (e.g., endangered health and life of the mother). This position--like the current position of the courts, which I think is approximately correct despite being based on viability--points out that there are more than two polar opposite positions in this debate.

In Vocab's final part, he talks a bit about the work that he and his wife do in caring for foster children. I commend him for that work, which is all-too-rare among opponents of abortion.

Thanks, Vocab, for the debate--and I still would like to hear a response from you in the comments on some of the issues that have been left hanging (e.g., in the comments on part 3).

UPDATE: It would probably be better to end this discussion with a summary that I already made in the comments on part 3:
We don't disagree that there is continuity of organism (just as there is continuity of a population of organisms over time)--all life on this planet is connected in that way. But just as we don't count every species as human, even in our own genetic lineage, we don't count every life stage of individual human organisms as persons. There's a sense in which "I" was once a zygote that had my same DNA, but at that stage there was no "me" there yet--there was nothing that it was like to be a zygote, to use Thomas Nagel's expression. In that same sense that "I" was a zygote, "I" will be a dead body in the future, even though there will at that point be nothing that it is like to be me, and the person that I am will be gone from the world though my body will briefly remain.

I think we understand each other's positions. You think that being a human organism is the same thing as to be a person, while I think personhood is a feature that comes into existence and persists for a subset of the life of an organism, that requires capacities of sentience or self-awareness.

But I think I can give reasons to support why my view makes moral, legal, and practical sense, and why human cultures and practices are more consistent with my view than yours. I don't think you can give such reasons, other than the brute assertion that human organisms are persons from start to finish. Your view has no need of the notion of person, yet it seems to me that there are all sorts of practical, moral, and legal reasons why we do need and use such a notion.

Vocab Malone on abortion and personhood, part 4

Vocab Malone has posted the fourth part of his essay on abortion and personhood, addressing the arguments from viability and wantedness. These are two more arguments that I don't place a whole lot of stock in, though perhaps some commenters will want to say more about.

The viability criterion is significant in that it's the basis of current federal case law on abortion since Roe v. Wade, but Vocab correctly notes that viability changes with the availability of technology, and that doesn't seem like a feature that should be relevant to whether one is a person. On the other hand, it is relevant to the notion of dependence--pre-viability is a time where, if you do grant that a fetus is a person, it's a person that is dependent for its existence upon another person. This raises questions of when it is morally permissible for a person upon whom another is dependent for their life to sever that dependence. Judith Jarvis Thomson's argument on abortion, which I referred to earlier in my response to part 1 of Vocab's essay, presents the following scenario:
You wake up in the morning and find yourself back to back in bed with an unconscious violinist. A famous unconscious violinist. He has been found to have a fatal kidney ailment, and the Society of Music Lovers has canvassed all the available medical records and found that you alone have the right blood type to help. They have therefore kidnapped you, and last night the violinist's circulatory system was plugged into yours, so that your kidneys can be used to extract poisons from his blood as well as your own. The director of the hospital now tells you, "Look, we're sorry the Society of Music Lovers did this to you--we would never have permitted it if we had known. But still, they did it, and the violinist is now plugged into you. To unplug you would be to kill him. But never mind, it's only for nine months. By then he will have recovered from his ailment, and can safely be unplugged from you." Is it morally incumbent on you to accede to this situation? No doubt it would be very nice of you if you did, a great kindness. But do you have to accede to it? What if it were not nine months, but nine years? Or longer still? What if the director of the hospital says. "Tough luck. I agree. but now you've got to stay in bed, with the violinist plugged into you, for the rest of your life. Because remember this. All persons have a right to life, and violinists are persons. Granted you have a right to decide what happens in and to your body, but a person's right to life outweighs your right to decide what happens in and to your body. So you cannot ever be unplugged from him."
My intuition is that in this scenario, it is morally supererogatory to remain connected to the violinist--it is not a moral requirement. The problem with this scenario is that it isn't quite analogous to pregnancy except in case of rape. If one gave voluntary consent to be connected to the violinist to save his life, it seems that one would have a moral duty to see it through. That raises the question of what constitutes "voluntary consent" with respect to pregnancy, which may occur accidentally or unintentionally despite use of contraception, for example. And note again that this scenario only applies in the case where personhood is taken as given, which I've been arguing is definitely not the case in early stages of a pregnancy.

The argument from wantedness, like the argument from viability, doesn't appear to be offer a criterion of personhood, but it is of course relevant to the overall abortion debate. Bringing into being persons who are not wanted and aren't going to be cared for is something that should be avoided, since the odds are not good for children in such circumstances. A controversial argument in Steven Levitt and Stephen Dubner's book Freakonomics is that there's a correlation between abortion rates and declining crime rates--i.e., the authors argued that a consequence of the unavailability of abortion is more unwanted children who become criminals. If that argument is correct (and I personally wouldn't bet on it), that's a form of evidence in favor of the availability of legal abortion, though I don't think it trumps a personhood argument. [NOTE (added Nov. 24, 2012): Levitt and Dubner's argument is thoroughly debunked in chapter 3 of Steven Pinker's The Better Angels of Our Nature: Why Violence Has Declined (pp. 119-121).  Freakonomics in general is found to be filled with errors in a review in the American Scientist by Andrew Gelman and Kaiser Fung.]

Vocab quotes from a book by abortion doctor Suzanne Poppema about her own abortion, in which she says to her embryo, "I’m very sorry that this is happening to you but there’s just no way that you can come into existence right now." He identifies this as "confused logic," since clearly the embryo already exists. I agree with Vocab that she has written this statement in an apparently confused way, but it could be made coherent if she had written of the embryo developing into a person or of a person coming into existence, which is probably what she meant to imply.
