Should minimally conscious patients be allowed to end their lives?

Two recent articles by neurobiologist and science writer Mo Costandi raise ethical quesions about the treatment of brain-damaged patients in the light of new research. Doctors distinguish between patients in a vegetative state, who are completely unresponsive and assumed to lack conscious awareness, and patients in a minimally conscious state, who some degree of responsiveness and are assumed to have some awareness – although it is unclear what their experiences are like and what mental abilities they have. A third category of patients are those in a “locked-in” state. These people are fully aware and awake, but paralysed and unable to communicate except through eye movements. Patients in a persistent vegetative state are highly unlikely to recover from it, and in most countries the law allows, under certain conditions, passive euthanasia for this group, for example by disconnecting a feeding tube that provides life support. But is this policy ethically defensible, and should we also allow euthanasia for patients with the other diagnoses?

Love drugs and science reporting in the media: Setting the record straight 

By Brian D. Earp, Julian Savulescu, and Anders Sandberg

Love. It makes the world go round. It is the reason we have survived as a species. It is the subject of our art, literature, and music—and it is largely the product of chemical reactions within the brain.

No wonder science is starting to unravel the ways in which we can influence it, and perhaps even control it.

Just as Darwin’s finding that we are descended from apes shocked people in the nineteenth century, so people will be shocked to find that our most lofty social ideal is something we share with our mammalian cousins and which is the subject of scientific scrutiny and even chemistry-book manipulation.

In 2008, two of us (Julian Savulescu and Anders Sandberg) published an article in the journal Neuroethics on the topic of “love drugs” – a term we use to refer to pharmacological interventions based on existing and future bio-technologies that could work to strengthen the bond between romantic partners. All three of us have an article just published in the journal Philosophy & Technology in which we build upon that earlier work. Interested readers will take the time to study those papers in full, but we have a feeling that much of the population will stop at a handful of media reports that have recently summarized our ideas, including at least one article that we think has the potential to mislead. Let us set the record straight.

‘Marriage is ONLY between a Man and a Woman’

A series of events have brought the issue of gay marriage to the fore. Nudged by the Vice President, Barak Obama came out in support. North Carolina, by contrast, voted to prohibit it. Closer to home, Mayor Boris Johnson recently put his foot down to prevent a religious group running the slogan ‘Not gay! Ex-gay, post-gay and proud. Get over it!’ on London buses. This was in response to an earlier ad from Stonewall which read ‘Some people are gay. Get over it.’ These events, of course, have triggered rekindling of the debate. What strikes me most about opposition to gay marriage is how bad many of the arguments against it seem to be.Read More »‘Marriage is ONLY between a Man and a Woman’

Bold Private John Smith, VC, modified ‘t’ allele of TPH1 SNP rs2108977

By Charles Foster

There’s a significant association of PTSD symptoms with a particular allele, according to a recently published study from UCLA and Duke. Some of the ethical consequences are already being discussed.  One consequence might be military. One might be able to detect and filter out PTSD-vulnerable recruits. Perhaps that’s a kindness. It would certainly seem militarily prudent. There might be legitimate qualms about creating a biologically callous warrior-class, but you’re not creating its components – you’re just collecting them together. You might not want to go to their parties, and you might wonder about the mutually brutalizing effect of corralling them in a barracks, but the exercise is really only a scientifically more informed version of the selection that goes on in any event. It’s not very interesting ethically.
But what if a gene for PTSD-resistance could be inserted or artificially switched on? It doesn’t seem fanciful. Should the military be permitted (or perhaps even required) to PTSD-proof their personnel?Read More »Bold Private John Smith, VC, modified ‘t’ allele of TPH1 SNP rs2108977

When the Law Should Ignore Incest

Worldwide media have been all over a case at the Strasbourg human rights court this week as it dismissed a man’s complaint over convictions for incest with his sister. Faced with a delicate moral question, the court ducked the issue, saying it fell within the ‘margin of appreciation’  (ie the area of discretion that the court leaves to member states in some areas of law). I think the law’s involvement in this case is a problem.

Psychiatric drugs to enhance conformity to religious norms, and conscientious objection

An article in the Israeli newspaper Haaretz reports on the (alleged) frequent use of psychiatric drugs within the Haredi community, at the request of the religious leaders, in order to help members conform with religious norms. Haredi Judaism is the most conservative form of Orthodox Judaism. It is sometimes referred to by outsiders as ultra-Orthodox. Haredim typically live in communities that have limited contact with the outside world. Their lives revolve around Torah study, prayer and family.

In December 2011, the Israel Psychiatric Association held a symposium entitled “The Haredi Community as a Consumer of Mental-Health Services”.  One of the speakers was Professor Omer Bonne, director of the psychiatry department at Hadassah University Hospital. Professor Bonne is claimed to have said that sometimes yeshiva students (yeshiva is a religious school) and married men should be given antidepressants even if they do not suffer from depression, because these drugs also suppress sex drive.

A moral argument against the war on drugs

By Julian Savulescu and Bennett Foddy 

Former Brazilian President, Fernando Henrique Cardoso, has argued that the war on drugs has failed and cannabis should be decriminalised. He argued that the hardline approach has brought “disastrous” consequences for Latin America. Having just returned from Rio, one can only agree. One of us was staying with an eminent professor of philosophy. We were returning to her house with her 11 year old daughter, only to have our way blocked by police with machine guns. They were hunting a drug lord in the local favela – this road was the only escape route and they were preparing for possible altercation.

Cardoso highlights the practical failure of a zero-tolerance approach. A zero tolerance approach to a crime like taking drugs must always fail, in the same way as a zero-tolerance approach to alcohol, prostitution or drugs in sport will always fail. Paradoxically, the worst thing you could do to the drug lords in Rio is not to wage a war on them, but to decriminalise cocaine and marijuana. They would be out of business in one day. Supplies could be monitored, controlled and regulated – the harm to users and third parties significantly reduced.

The case for legalizing drugs has been made often, most recently by Cardoso and by Australia’s foreign minister, Bob Carr, who this week co-signed a report declaring that ‘the war on drugs has failed’. The argument is nearly always put forward in terms of the burdens that the drug war has imposed on us in terms of crime and public health. And it is true that these things give us good reason to abandon Nixon’s war on drugs. But we so rarely hear a moral argument in favour of liberalizing drug laws. This is a mistake. Although experts have told us time and time again that things would be better without the drug war, politicians have ignored the expert advice because voters do not want drugs laws to be loosened. And voters feel this way not because they think they know better than the experts, but because they have moral objections to drug use. There is a hidden moral debate driving the war on drugs that we never seem to bring out in the open.

New Study Detects Free Will in the Prefrontal Cortex (UPDATED)

An impressive study to be released in the journal Science on Monday uses new imaging techniques to reveal exercises of free will occurring in the brain. The authors scanned participants in their experiments who were choosing a playing card from a freshly shuffled deck. One group of subjects were asked to: “Pick a card, any card” (using their free choice), whereas a control group were asked to select various specific cards (simply obeying a command). The explanation of how precisely free will was detected is somewhat technical, but it can be roughly understood this way: by subtracting the brain activity of the control group from those in the free will group, the experimenters were able to observe free will in the differences. They found numerous traces of free will occurring in the prefrontal cortex, which has traditionally been thought to be the seat of executive control.

Kony 2012 and Saying What You Mean

Kony 2012 has become the highest profile issue of international justice on social media by far. For those without a Facebook account, Kony 2012 is a slick 30-minute YouTube film about Joseph Kony, leader of the Lords Resistance Army. The video explicitly seeks to mobilise support for efforts to arrest Kony, who has been indicted by the International Criminal Court for crimes against humanity, particularly against children. As I type, the video, released Monday, is approaching 70 million views. The video has also attracted a fair share of criticism, much of which I’m not sure is honest.
