In vitro meat, new technologies, and the “yuck factor”

In vitro meat, recently discussed on this blog by Julian Savulescu, is gradually becoming a reality. It holds great promise, notably considering that billons of animals are slaughtered for food every year, often after spending miserable lives in factory farms, and that the current production of meat contributes significantly to the emission of greenhouse gases. In spite of those facts, it seems highly unlikely that most meat-eaters will agree to give up meat anytime soon (though the success of the “meat-free Mondays” initiative in a number of different places should be saluted), yet they might well prove more willing to switch from traditionally produced meat to in vitro meat, if the latter were as healthy (or even healthier), reasonably priced, and tasted the same as the former.

 

Discussions of in vitro meat in the media most often cite the so-called “yuck factor” as a major obstacle to its general acceptance: i.e. the instinctive revulsion that many people feel at the idea of eating “unnatural” meat grown in a petri dish. I am inclined to be cautiously optimistic about the prospects of overcoming that obstacle: “unnatural” meat substitutes have already become popular among vegetarians, and some meat-eaters do consume them as well occasionally. Although in vitro meat should bear even more of an uncanny resemblance to the real thing than those substitutes (which might be why some people are revulsed by the idea), I would expect it to find success if issues of health and taste can be adequately dealt with. Now what if the yuck factor were to prove more of an issue than I anticipate? I believe the following points deserve to be emphasized:

Rick Santorum, birth control, and “playing God”

Rick Santorum thinks that birth control is immoral. Santorum, a former Senator from Pennsylvania, is one of two human beings – if the polls have it right – likeliest to become the Republication nominee for President of the United States this election cycle.

“Liberals Are Disgusting”: In Defence of the Publication of “After-Birth Abortion”

Editorial note: John Harris has responded to this post to clarify his position on infanticide. You can find the relevant post here.

The Journal of Medical Ethics prepublished electronically an article by Alberto Giubilini and Francesca Minerva entitled “After-birth abortion: why should the baby live?”

This article has elicited personally abusive correspondence to the authors, threatening their lives and personal safety. The Journal has received a string abusive emails for its decision to publish this article. This abuse is typically anonymous.

I am not sure about the legality of publishing abusive threatening anonymous correspondence, so I won’t repeat it here. But fortunately there is plenty on the web to choose from. Here are some responses:

“These people are evil. Pure evil. That they feel safe in putting their twisted thoughts into words reveals how far we have fallen as a society.”

“Right now I think these two devils in human skin need to be delivered for immediate execution under their code of ‘after birth abortions’ they want to commit murder – that is all it is! MURDER!!!”

“I don‘t believe I’ve ever heard anything as vile as what these “people” are advocating. Truly, truly scary.”

“The fact that the Journal of Medical Ethics published this outrageous and immoral piece of work is even scarier”

(Comments selected from The Blaze, which features the article as a news item )

As Editor of the Journal, I would like to defend its publication. The arguments presented, in fact, are largely not new and have been presented repeatedly in the academic literature and public fora by the most eminent philosophers and bioethicists in the world, including Peter Singer, Michael Tooley and John Harris in defence of infanticide, which the authors call after-birth abortion.

Love and other drugs, or why parents should chemically enhance their marriages

Love and other drugs, or why parents should chemically enhance their marriages

Valentine’s day has passed, and along with it the usual rush of articles on “the neuroscience of love” – such as this one from Parade magazine. The penner of this particular piece, Judith Newman, sums up the relevant research like this:

It turns out that love truly is a chemical reaction. Researchers using MRIs to look at the brain activity of the smitten have found that an interplay of hormones and neurotransmitters create the state we call love.

My humble reckoning is that there’s more to “the state we call love” than hormones and neurotransmitters, but it’s true that brain chemistry is heavily involved in shaping our experience of amour. In fact, we’re beginning to understand quite a bit about the cerebral circuitry involved in love, lust, and human attachment—so much so that a couple of Oxford philosophers have been inspired to suggest something pretty radical.

They think that it’s time we shifted from merely describing this circuitry, and actually intervened in it directly—by altering our brains pharmacologically, through the use of what they call “love drugs.”

Obligatory Ventilation: why Elective Ventilation should not be elective

On the BBC’s Moral Maze this evening, the question of elective ventilation was discussed at some length. (For those who missed it, the program is still available here). There were several striking features of that discussion, but one argument that stood out was the argument against elective ventilation based on the importance of respecting the autonomy of patients, and the absence of consent, This has been the basis of previous ethical concerns about Elective Ventilation.

But actually, it seems to me that the consent/autonomy argument is completely upside down.* Patient autonomy provides one of the strongest arguments in favour of elective ventilation. So strong, in fact, that the proposed form of Elective Ventilation should arguably not be ‘elective’. It is morally obligatory that we embrace Elective Ventilation.Read More »Obligatory Ventilation: why Elective Ventilation should not be elective

Back from the grave: Should we allow Elective Ventilation?

Mary is 62 years old. She is brought to hospital after she collapsed suddenly at home. Her neighbour found her unconscious, and called the ambulance. When they arrived she was deeply unconscious and at risk of choking on her own secretions. They put a breathing tube in her airway, and transported her urgently to hospital.

When Mary arrives she is found to have suffered a massive stroke. A brain scan shows very severe bleeding inside her brain. In fact the picture on the scan and her clinical state is described by the x-ray specialist as ‘devastating’. She is not clinically brain dead, but there is no hope. The emergency department doctors have contacted the neurosurgical team, but they have decided not to proceed with surgery as her chance of recovery is so poor.

In Mary’s situation, the usual course of events is to contact family members urgently, to explain to them that there is nothing more that can be done, and to remove her breathing tube in the emergency department. She would be likely to die within minutes or hours. She would not be admitted to the intensive care unit – if called, the ICU team would be likely to say that she is not a “candidate” for intensive care. However, new guidance from the National Institute of Clinical Effectiveness, released late last year, and endorsed in a new British Medical Association working paper, has proposed a radical change to this usual course of events.Read More »Back from the grave: Should we allow Elective Ventilation?

Is Drug Addiction a Lifestyle Choice?

According to BBC News this week, the brains of some people “may be wired for addiction.” A study has come out in the journal Science that presents evidence of abnormal brain structures that were found in drug addicts and their non-addicted siblings. The lead researcher, Dr Karen Ersche, was quoted by the BBC as saying that the study “shows that drug addiction is not a choice of lifestyle, it is a disorder of the brain and we need to recognize this.”

Has the Ersche et al study in fact shown that drug addiction is not a lifestyle choice? Has it proven that drug addicts should be treated as innocent patients with medical problems rather than being subject to moral censure for their failure to exert self-control, and for their irresponsible and often deeply anti-social behaviour? No! In fact, it is likely that no possible neuroscientific evidence could show such a thing.

Health warning: You may find brain scan images like these confusing!

Nothing to lose? Killing is disabling

In a provocative article forthcoming in the Journal of Medical Ethics (one of a new series of feature articles in the journal) philosophers Walter Sinnott Armstrong and Franklin Miller ask ‘what makes killing wrong?’ Their simple and intuitively appealing answer is that killing is wrong because it strips an individual of all of their abilities – acting, moving, communicating, thinking and feeling.

So what, you might ask? If this is right, say Sinnott-Armstrong and Miller, it means that it would be just as bad to commit an act that caused someone to be in a permanent vegetative state, as it would to kill them.Read More »Nothing to lose? Killing is disabling

Practical Ethics Given Moral Uncertainty

Practical ethics aims to offer advice to decision-makers embedded in the real world.  In order to make the advice practical, it typically takes empirical uncertainty into account.  For example, we don’t currently know exactly to what extent the earth’s temperature will rise, if we are to continue to emit CO2 at the rate we have… Read More »Practical Ethics Given Moral Uncertainty
