Vocab Malone has put up his first post arguing for the position that “the unborn human embryo is a full person at the moment of conception and should be afforded the full rights due human beings by their very essence." Criteria of Personhood or Humanity He starts by looking at the question of what it is to be human or to be a person, citing a few historical references of individual characteristics–being rational, being “in relationship,” and “the capacity for self-objectification.” He expresses doubt that any single characteristic is appropriate, on the grounds that human beings undergo changes of state such as being asleep or being drugged, or not thinking. I agree with him that the characteristics he has listed won’t do the trick, and I also agree with him that features that go away when we sleep are inadequate. But it doesn’t follow that there is no single feature that can do the trick–if the feature is a capacity that we have, for example, that capacity doesn’t cease to exist when it’s not being used. He goes on to note that lack of personhood doesn’t entail that any treatment is morally permissible, pointing out animals as examples of nonpersons that deserve humane treatment. Again, I agree with him–and observe the converse, that possession of personhood doesn’t mean that there are no cases where it can be moral to kill a person–cases of self-defense, euthanasia, capital punishment, or war come to mind as possibilities. But what makes animals deserve humane treatment is that they have certain capacities and interests, such as an inner mental life that includes at the very least the ability to feel sensations–and note that humane treatment doesn’t necessarily entail a right to life on the part of an animal, or a duty on our part not to kill them. Vocab appears to want to lay the groundwork for rejecting the use of a criterion of personhood in favor of a criterion of humanity as his standard for arguing against abortion, but here he only offers a promissory note and doesn’t provide an argument to that effect. I think this is a mistake, however, because ethical distinctions should be based on morally relevant features, and I don’t believe species membership is any more relevant in and of itself to being the holder of rights or of being the object of duties than is race or gender. If a member of an intelligent alien species capable of language were to make contact with us, my intuition is that we would attribute personhood to that entity and give it the same consideration as a human being. Likewise if we manage to build artificially intelligent, self-directed machines with beliefs, desires, and intentions, though the intuition is not as strong there unless I imagine them to have mental lives similar to our own. Conception: Fertilization Even though Vocab hasn’t yet given a reason to reject a personhood criterion in favor of a human being criterion, the rest of his case is solely about human life rather than personhood, which I think is the wrong issue for the reasons I just gave. He argues that human life begins at conception, and clarifies that he means fertilization rather than implantation. This choice means that 30-50% of human lives are spontaneously aborted due to the failure of the fertilized ova to implant in the uterine wall. If Vocab thinks that this loss of human life is the loss of beings with rights and interests to whom we owe a duty to enable them to live out normal lives, then he has some explaining to do. First of all, why would a loving God create a human reproductive system that resulted in such a Holocaust of lives lost before they get a chance to start? Second, why has no one considered this to be a serious ethical problem that we need to urgently devote medical resources to address? We can call this the problem of natural abortion, which has both a natural evil and human evil component that requires justification. Complete at Fertilization? Vocab says that at conception (by which he means fertilization), “every human is complete and alive.” I agree that a fertilized human ovum is alive–as life is a continuous process, arising from living components, at least until synthetic biology gets to the point of creating life from entirely nonliving components. Sperm and ova are also alive. But it is certainly not complete–zygotes have no brains, no central nervous systems, no organs, no body parts other than undifferentiated, identical cells. An Individual at Fertilization? Vocab also says that at fertilization and pre-implantation, “it is not merely a collection of cells lumped together but an actual individual.” This also need not be the case. At fertilization, a zygote is an undifferentiated cell that undergoes a process of division without changing size for several days, to become a blastocyst by about the fifth day. During this period each of its cells is totipotent, meaning that each individual cell has the potential to become a full human being. Sometimes more than one of the cells does become a separate human being, as in the case of identical twins. In the case of identical twins, if they don’t split completely, they may become conjoined twins or parasitic twins, or one twin may be completely absorbed into the other or otherwise fail to develop and become a vanishing twin. Where a vanishing twin occurs with fraternal twins, the resulting individual can be a chimera, with two sets of DNA. Should we also grieve for those twins who fail to develop, either due to failure to split off or failure to develop? The science fiction scenarios of teleportation that create interesting philosophical puzzles for the notion of personal identity are real puzzles for a view that attributes personhood to zygotes, though without the additional problem of memories and experiences, since zygotes are undifferentiated cells. Blastocysts Once the zygote becomes a blastocyst, it forms into an outer layer of cells, which later becomes the placenta, and an inner cell mass of pluripotent embryonic stem cells, each of which is capable of differentiating into any kind of human cell. Only after this stage does the blastocyst implant in the wall of the uterus, about a week after fertilization, and begin taking nutrients directly from the blood of the mother–a dependency that can itself be of moral significance, as Judith Jarvis Thomson’s violinist argument shows. As already mentioned above, a great many fertilized ova do not reach this stage. Further, the percentages of implant failure are higher for in vitro fertilization (IVF), a procedure which Vocab’s criteria would have to declare unethical, even though it is the only way that many couples can have their own biological offspring. It should also be noted that the process of therapeutic cloning involves taking a female ovum (which Vocab doesn’t seem to indicate he considers to be a bearer of rights on its own), removing its haploid DNA, inserting the nucleus from a (diploid) human somatic cell (this is called somatic cell nuclear transfer), and giving it a shock to cause it to start dividing just like a fertilized egg. This occurs without fertilization by a human sperm. Once it reaches the blastocyst stage, its inner cell mass is harvested for embryonic stem cells, which destroys the blastocyst in the process. The natural process of fertilization never takes place, but there’s little doubt that reproductive human cloning is possible via this process. Vocab’s choice of fertilization as key suggests that there is no moral issue with this process, even though it also has some potential to become a human being. Further, if fertilization is a necessary, not just a sufficient, condition for rights, Vocab’s view suggests that human clones would have no rights. Fully Programmed? Vocab goes on to say that “the embryo is already ‘fully programmed’ (to use computer language). This means the pre-implanted embryo needs no more information input at any further point in its development.” While this was formerly believed to be the case about the individual embryo’s biology, we now know that the environment of development can play a role in the characteristics that will come to be exhibited, such as from mRNA supplied from the mother to a developing embryo after fertilization and prior to zygote formation. But in any case, I would maintain that it’s not our cellular biology that gives us moral value, as opposed to our capacities to have interests, desires, intentions, plans, sensations, and so forth–all capacities that zygotes lack. Vocab ends this piece with some anthropomorphizing of zygotes, which appears to me to be a highly misleading form of argument–his analogies cannot be taken literally, since zygotes have no mental processes. Human and Living = Human Being? I agree with Vocab that a fertilized human ovum is living, that it’s human, and that, if all goes well, it will become one (or more) individual human beings. I don’t agree that it’s yet a person or a “human being,” since it lacks the requisite parts and capacities. To sum up: ...

Local Christian hip-hop artist and slam poet Vocab Malone, who I’ve interacted with online and met when Daniel Dennett spoke at ASU early this year, asked me in January for my thoughts on abortion and personhood. He’s now written a paper on the subject which he’s asked me to critique, and we thought it would be interesting to see how it would work out to do it in a public manner via our respective blogs. The plan is that he will post successive sections of his paper on his blog, and I’ll respond here, with cross-links to share some traffic and discussion. Both of us allow blog comments; it probably makes the most sense to post your comments at the blog for the person you’d like to see a response from. Vocab has posted an introduction and the comments that I originally sent to him on the subject at his blog, Backpack Apologetics. He’s taking a position that I think is very difficult to justify, that full personhood and human rights are acquired at the moment of conception–we’ll have to see which definition of conception he chooses, fertilization or implantation. Just to throw out a little issue I raised this semester in one of my classes–some have argued that climate change raises the ethical issue of a duty to future generations. If we can have moral duties now to people who don’t exist at all yet, what does that imply about duties to embryos? ...

SkeptiCamp founder Reed Esau has finally taken the plunge and started blogging at “an illustrative account”–check out his interesting post on “Taking Ownership in Skepticism." Historical Comments Anonymous (2009-12-09): Thanks for the mention, Jim. Some of the fallout that I hinted-at can be found at Why Skeptics Don’t Have to be Atheists with a response by De Dora on Thursday.

While past studies have shown religious believers to be happier than nonbelievers, some new analysis shows that it’s not quite so simple. Luke Galen has found that the convinced non-religious are also quite happy, but people who are uncertain are the ones who are dissatisfied. Adam Okulicz-Kozaryn has analyzed data from the World Values Survey and found some more interesting details: Religious people are both happier and unhappier. While a higher percentage of religious people report themselves as extremely happy than convinced nonbelievers, a higher percentage of religious people also report themselves as extremely unhappy.Those who attend religious services and belong to religious organizations tend to be happier. And that’s whether or not they believe–in fact among that group, those with the stronger belief tend to be unhappier. So it’s the social aspect, not the doctrine, that promotes happiness. And this is further supported by:The more religious a country is, the happier believers are, and vice versa. In religious countries, believers are happier; in nonreligious countries, nonbelievers are happier. See more at the Epiphenom blog. (Cross-posted to the Secular Outpost.)

I’ve posted comments about the reasons to be skeptical about Rom Houben’s facilitated communication at a number of blogs, where the response of some seems to be that there is no point of such testing. The reasons for not testing have included (1) that the videos are a “straw man”; (2) that criticisms from a stage magician and a philosopher/bioethicist are not worthy of attention; and (3) the testimony from Dr. Laureys, the facilitator Mrs. Wouters, and Houben’s family is much stronger evidence than what we can see in the videos, and that Dr. Laureys says he already conducted a single-blind test which showed that the communication came from Houben, not the facilitator, and to reject that is irrational hyper-skepticism that assumes they are lying. The first argument makes no sense to me. The videos clearly show the facilitator rapidly typing away with Houben’s finger even while he’s looking away or has his eyes closed, which is by itself a very strong reason to be skeptical, especially in light of the past record of facilitated communication. The second argument is not only ad hominem, but further refuted by similar analysis by a neuroscientist. The last argument is a bit better, but wrongly assumes that the only alternative is that the doctor and family are lying. Facilitated communication isn’t a matter of conscious fraud, it’s a matter of self-deception of the facilitator (enhanced by the expectations and reactions of the family). Given the possibility of unconscious cuing of the facilitator by the doctor, as well as his own vested interest in a positive result, the test he described doing is still far from sufficient to overcome the evidence plainly displayed in the videos. Unfortunately, there is a very strong incentive to believe on the part of the doctor, the facilitator, and the family. To find that the communications are coming from the facilitator would be emotionally devastating, and detrimental to the doctor’s credibility. To test further is to risk a huge potential loss of what has apparently been gained, and I suspect it’s unlikely that we’ll see it happen. But look at it from Houben’s own perspective–further testing is absolutely in his own best interests. For if the facilitator is the one doing the communicating, not him, then he is being further exploited for the satisfaction of his doctor, facilitator, and family, not for his own benefit. He’s not being treated respectfully or as an end, rather than as a means. If he is, in fact, minimally conscious as the brain scans suggest, then speaking on his behalf without his genuine input is doing him even greater harm. If you reject the idea that an hour or so of Houben’s time should be used to do a conclusive, double-blind test to see whether the communications are coming from him or from the facilitator, is it because you want to believe, rather than to know? There is clear possible harm to Hoeben from not doing such a test. There is no harm to Hoeben from such a test, though there’s clearly the risk of painfully dissolving an illusion for the doctor, facilitator, and family. But Hoeben’s interests should be placed above that risk. (Previously on Houben, a post with many links and references.) UPDATE (February 15, 2010): Houben has been put to the test, and it turns out the communications were, in fact, coming from the facilitator. UPDATE (February 20, 2010): David Gorski at the Science-Based Medicine blog has a bit more from the Belgian Skeptics, who were involved in the test. ...

Dana Perino says, “We did not have a terrorist attack on our country during President Bush’s term." Sean Hannity ignores it. Terrorism is a strategy used by a militarily weak group against a militarily strong one, to create fear, dread, and uncertainty among the general population toward some political or ideological end, such as ending military actions by the strong group against the weak. It’s not clear to me that Major Hasan’s attack at Fort Hood meets the criteria of a terrorist attack, or even a religiously motivated one, though that’s somewhat more plausible. His action did share the element of being an attack by the weak against the strong, but he also appears to have had mental issues and an ongoing battle with the military over his desire to get out and not be sent to Afghanistan. There were clear warning signs that were missed or ignored, but it doesn’t appear that he was part of a broader plot. The Fort Hood shootings were a tragedy, and possibly one that could have been avoided. But it certainly isn’t an event that provides justification for torture, warrantless wiretapping, the revocation of habeas corpus, and the expansion of “homeland security” to the detriment of our civil liberties. Perino and Hannity want to argue that the Obama administration has made us less safe on the basis of this incident, which makes about as much sense as blaming the Bush administration for the Virginia Tech shootings. UPDATE (November 27, 2009): As a couple people have correctly noted, I should also have mentioned the post-9/11 anthrax attacks as another terrorist act Perino forgot about. Richard Reid, the shoe bomber, was another. UPDATE: Hume’s Ghost notes that Perino has said via Twitter that she meant “since 9/11," and correctly points out how absurd it is to discount 9/11 for Bush (as well as these other subsequent events she’s ignored), while blaming Obama for Hasan’s shooting: “…while there were warning signs about Hasan’s fitness for duty that could have been noticed by those around him, this is hardly something that would have been on the President’s radar. No one was briefing President Obama that Major Hasan was determined to strike a military base; however, President Bush was briefed that Bin Laden was determined to strike in the United States prior to the 9/11 attacks.” ...

Wikileaks is releasing over 500,000 U.S. national text pager intercepts from September 11, 2001, over the next two days: From 3AM on Wednesday November 25, 2009, until 3AM the following day (New York Time), WikiLeaks will release over half a million US national text pager intercepts. The intercepts cover a 24 hour period surrounding the September 11, 2001 terrorist attacks in New York and Washington. The first message, corresponding to 3AM September 11, 2001, five hours before the first attack, will be released at 3AM November 25, 2009 and the last, corresponding to 3AM September 12, 2001 at 3AM November 26, 2009. Text pagers are mostly carried by persons operating in an official capacity. Messages in the collection range from Pentagon and New York Police Department exchanges, to computers reporting faults to their operators as the World Trade Center collapsed. This is a significant and completely objective record of the defining moment of our time. We hope that its entry into the historical record will lead to a deeper and more nuanced understanding of how this tragedy and its aftermath may have been prevented. While we are obligated by to protect our sources, it is clear that the information comes from an organization which has been intercepting and archiving national US telecommunications since prior to 9/11.The Transparent Society getting closer, it appears…

Numerous mass media outlets and blogs are reporting on the misdiagnosis of Rom Houben of being comatose for 23 years when he was really conscious, according to Belgian neurologist Steven Laureys, who has claimed for years to be able to treat patients allegedly in a persistent vegetative state with electric shocks and find that they were really in a minimally conscious state. Videos of Houben show him allegedly communicating via a keyboard which is pressed by a single finger on one hand–but his hand is being held by a facilitator, and he’s not even looking at the keyboard. Some still photos show the facilitator looking intently at the keyboard, while Houben’s eyes are closed. James Randi observes that this looks just like the self-deception of Facilitated Communication that was promoted as a way to communicate with severely autistic people, and Marshall Brain at How Stuff Works seconds that conclusion. I think it’s a bit too fast to conclude that Houben’s not conscious–brain scans could indeed have provided good evidence that he is. But what would be worse than having “locked-in syndrome”? Having somebody else purporting to speak for you with ideomotor-driven Facilitated Communication, while you were helpless to do anything about it. I’d like to see some double-blind tests of Houben, where he’s asked questions about events that occur when the facilitator isn’t present, as well as fMRI results during the process of facilitation (since there are brain activation differences between active and passive activities, which have been used to study such things as the perception of involuntariness during hypnosis–it shows features of both active and passive movement). I’d also like to see further opinion on Laureys methodology and diagnosis–it seems he has significant self-interest in promoting this case. UPDATE: Brandon Keim at Wired Science has finally asked the questions that those who have reported this in the mainstream media should have been asking. Here’s a 2001 review of the scientific literature on facilitated communication. UPDATE: The video on this story shows the facilitator typing for him while his eyes are closed and he appears to be asleep. UPDATE: A Times Online story claims that Houben’s facilitator, Linda Wouters, spent the last three years working with Houben to learn to feel tiny muscle movements in his finger, and that Dr. Laureys did tests to validate the technique: ...

Hackers got access to a trove of private emails from the University of East Anglia’s Climate Research Unit that is being trumpeted by those who disbelieve in anthropogenic global warming as proof of scandal. I’ve looked through the data a bit myself–you can find a searchable archive of the emails here. I suspect this collection of emails may end up being put to good research use as the Enron email corpus was. While I found a few embarrassing things, I found no evidence of outright data fabrication or fakery. The main email that has been cited as such evidence is an email from Phil Jones that says: I’ve just completed Mike’s Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) and from 1961 for Keith’s to hide the decline.Gavin Schmidt at RealClimate explains: The paper in question is the Mann, Bradley and Hughes (1998) Nature paper on the original multiproxy temperature reconstruction, and the ‘trick’ is just to plot the instrumental records along with reconstruction so that the context of the recent warming is clear. Scientists often use the term “trick” to refer to a “a good way to deal with a problem”, rather than something that is “secret”, and so there is nothing problematic in this at all. As for the ‘decline’, it is well known that Keith Briffa’s maximum latewood tree ring density proxy diverges from the temperature records after 1960 (this is more commonly known as the “divergence problem”–see e.g. the recent discussion in this paper) and has been discussed in the literature since Briffa et al in Nature in 1998 (Nature, 391, 678-682). Those authors have always recommend not using the post 1960 part of their reconstruction, and so while ‘hiding’ is probably a poor choice of words (since it is ‘hidden’ in plain sight), not using the data in the plot is completely appropriate, as is further research to understand why this happens.In other words, “hiding” in this case is using temperature measurement records instead of tree rings as a proxy for temperature records for a period of time where the tree rings are known not to be an accurate proxy, for whatever reason. It’s also claimed that these emails show a concerted effort to subvert the peer review process and stop publications by climate change skeptics, but most of those emails seem to center around an issue where the scandal was actually from the skeptics–the publication of a 2003 paper by Willie Soon and Sallie Baliunas in the journal Climate Research that was considered by 13 authors of papers cited to have misrepresented their work. Subsequently, half of the editorial staff of the journal resigned in protest at what they saw as a failure of peer review, and the managing director of the journal’s parent company issued an apology (see Wikipedia’s summary). The emails show that these scientists were upset by Climate Research’s publication of bad science and encouraged protest and those resignations. A few blog posts that seem to have good overviews of the issues: Skeptical Science, “What do the hacked CRU emails tell us?"Real Climate, “The CRU Hack” (followed by over 1,000 comments)Real Climate, “The CRU Hack: Context” (gives background on some of the issues, including the above Climate Research issue). Greenfyre’s, “Climate change Deniers hoax themselves… again."Millard Fillmore’s Bathtub, “Smoking guns in the CRU stolen emails: A real tale of real ethics in science” (what the CRU emails show about treatment of an erroneous climate science paper) An interesting comparison to past scientific controversy is: Carbon Fixated, “Newtongate: the final nail in the coffin of Renaissance and Enlightenment ’thinking’"And, to compare to the climate change skeptics: Bishop Hill, “Climate cuttings 33” (summary of the apparent worst issues)Essex County Conservative Examiner, “Hadley [sic] CRU hacked with release of hundreds of docs and emails”Climate Audit, “CRU Correspondence”Watt’s Up With That, “Mike’s Nature Trick”Watt’s Up With That, “CRU Emails ‘may’ be open to interpretation, but commented code by the programmer tells the real story”Watt’s Up With That, “Spencer on elitism in the IPCC climate machine”The last of these posts, from Univ. of Alabama climate scientist and skeptic Roy W. Spencer, notes that: If all of this sounds incompatible with the process of scientific investigation, it shouldn’t. One of the biggest misconceptions the public has about science is that research is a straightforward process of making measurements, and then seeing whether the data support hypothesis A or B. The truth is that the interpretation of data is seldom that simple. ...

Yesterday I heard Joel Garreau speak again at ASU, as part of a workshop on Plausibility put on by the Consortium for Science, Policy, and Outcomes (CSPO). I previously posted a summary of his talk back in August on the future of cities. This talk was based on his book, Radical Evolution: The Promise and Peril of Enhancing Our Minds, Our Bodies–and What It Means to Be Human. Garreau was introduced by Paul Berman, Dean of the Sandra Day O’Connor School of Law at ASU, who also announced that Garreau will be joining the law school faculty beginning this spring, as the Lincoln Professor for Law, Culture, and Values. He began by saying that we’re at a turning point in history [has there ever been a time when we haven’t thought that, though?], and he’s going to present some possible scenarios for the next 2, 3, 5, 10, or 20 years, and that his book is a roadmap. The main feature of this turning point is that rather than transforming our environment, we’ll be increasingly transforming ourselves, and we’re the first species to take control of its own evolution, and it’s happening now. At some point in the not-too-distant future, he said, your kid may come home from school in tears about how he can’t compete with the other kids who are more intelligent, more athletic, more attractive, more attentive, and so forth–because you haven’t invested in the human enhancement technologies coming on the market. Your possible reactions will be to suck it up [somebody’s still gotta do the dirty jobs in society?], remortgage the house again to make your kid competitive, or try to get the enhanced kids thrown out of school. What you can’t do is ignore it. He then asked people to raise their hands who could remember when things were still prevalent: ...
