A trial to see if it is possible to regenerate brains in patients that have been declared clinically dead has been approved. Reanima Advanced Biosciences aims at using stem cells, injections of peptides, and nerve stimulation to cause regeneration in brain dead patients. The primary outcome measure is “reversal of brain death as noted in clinical examination or EEG”, which at least scores high on ambition. The study accepts healthy volunteers, but they need to be brain dead due to traumatic brain injury, which might discourage most people.
Is there any problem with this? Continue reading
I am a bitter opponent of private education. All my political hackles rise whenever the subject is mentioned.
Yet of my four currently school-aged children, one (‘A’) is educated privately (at a specialist choir school), and another (‘B’, who is dyslexic) will shortly be in private education (at a hip, Indian-cotton swathed, high-fibre, bongo-drumming, holistic school). The two others (‘C’ and ‘D’) are currently in state primary schools. There are two older children too (‘E’ and ‘F’) They were both educated privately, at a fairly traditional school.
How can I live with myself?
One way would be to avert my eyes from the apparently plain discrepancy between my actions and my political convictions. That’s often been my strategy. But I want to attempt some kind of defence – at least in relation to A and B, and lay the ground for a potential defence in relation to C and D, should we choose to educate them privately.

Everyone I know thinks it’s obscene, and that the suffering of the dogs cannot possibly be outweighed by the sensual satisfaction of the diners, the desirability of not interfering, colonially, with practices acceptable in another culture, or by any other consideration. It’s just wrong.
‘It’s just wrong’ is the observation that moral philosophers exist to denounce. They draw their salaries for interrogating this observation, exploding its naivety, and showing that the unexamined observation is the observation not worth making.
But what can the moral philosophers bring to the discussion about the Chinese dogs? Alone, and unaided by science, not much. The philosophy turns out to be either (a) reheated science or (b) a description of our intuitions, together with more or less bare assertions that those intuitions are either good or bad.

Science and medicine have done a lot for the world. Diseases have been eradicated, rockets have been sent to the moon, and convincing, causal explanations have been given for a whole range of formerly inscrutable phenomena. Notwithstanding recent concerns about sloppy research, small sample sizes, and challenges in replicating major findings—concerns I share and which I have written about at length — I still believe that the scientific method is the best available tool for getting at empirical truth. Or to put it a slightly different way (if I may paraphrase Winston Churchill’s famous remark about democracy): it is perhaps the worst tool, except for all the rest.
Scientists are people too
In other words, science is flawed. And scientists are people too. While it is true that most scientists — at least the ones I know and work with — are hell-bent on getting things right, they are not therefore immune from human foibles. If they want to keep their jobs, at least, they must contend with a perverse “publish or perish” incentive structure that tends to reward flashy findings and high-volume “productivity” over painstaking, reliable research. On top of that, they have reputations to defend, egos to protect, and grants to pursue. They get tired. They get overwhelmed. They don’t always check their references, or even read what they cite. They have cognitive and emotional limitations, not to mention biases, like everyone else.
At the same time, as the psychologist Gary Marcus has recently put it, “it is facile to dismiss science itself. The most careful scientists, and the best science journalists, realize that all science is provisional. There will always be things that we haven’t figured out yet, and even some that we get wrong.” But science is not just about conclusions, he argues, which are occasionally (or even frequently) incorrect. Instead, “It’s about a methodology for investigation, which includes, at its core, a relentless drive towards questioning that which came before.” You can both “love science,” he concludes, “and question it.”
I agree with Marcus. In fact, I agree with him so much that I would like to go a step further: if you love science, you had better question it, and question it well, so it can live up to its potential.
And it is with that in mind that I bring up the subject of bullshit.

This is a cross-post of an article which was originally published in The Conversation
Effective altruism is a philosophy and social movement which aims not only to increase charitable donations of time and money (and indeed more broadly to encourage leading a lifestyle which does good in the world), but also encourage the most effective use of these resources, usually by looking for measurable impacts such as lives saved per dollar.
For an effective altruist, the core question is: “Of all the possible ways to make a difference, how can I make the greatest difference?” It might be argued, for example, that charity work isn’t the best use of time; a talented financier may be better off working for a bank, and use their earnings to pay for others to work for charities instead.

Every day, for about thirty-five minutes, I sit cross-legged on a cushion with my eyes shut. I regulate my breath, titrating its speed against numbers in my head; I watch my breath surging and trickling in and out of my chest; I feel the air at the point of entry and exit; I export my mind to a point just beyond my nose and pour the breath into that point. When my mind wanders off, I tug it back.
The practice is systematic and arduous. In some ways it is complex: it involves 16 distinct stages. When I am tired, and the errant mind won’t come quietly back on track, I find it helpful to summarise the injunctions to myself as:
- I am here
- This is it
I alternate the emphases: ‘I am here’: ‘I am here’; ‘I am here’; ‘This is it’; ‘This is it’; ‘This is it.’
I note (although not usually, and not ideally, when I’m in the middle of the practice) that each of these connotations presumes something about the existence of an ‘I’. This is less obvious with the second proposition, but clearly there: ‘This’ is something that requires a subject. Continue reading
Scott Alexander has a thoughtful piece about who gets to set the default in disagreements about what is reasonable. He describes a couple therapy session where one member is bored with his sex life and goes kinky clubbing, to the anger of his strongly monogamous partner. Yet both want to stay together at least for the sake of the kids. Assuming the answer is an either-or situation where one has to give up on their demand (likely not the ideal response in an actual couple therapy setting), the issue seems to boil down to who has the unreasonable demand.
It resonated with another article I came across in my news flow today: What It’s Like to Be Chemically Castrated. This article is an interview with a man who wanted to be chemically castrated in order to manage his sex addiction and save his 45-year marriage. Is this an unreasonable intervention?
Marriage is not well served by its defenders. The loudest and best reported of them are often fundamentalist bigots. It’s a shame, for marriage has a lot going for it.
Even if you think that marriage is an anachronistic/bourgeois/theologically contaminated institution, you’ll probably agree that the breakdown of marriages is best avoided. Of course incurably dysfunctional marriages should be ended, but most people aspire to enduring relationships, and the wrench of marital dislocation is emotionally and financially traumatic. If there are children, marriage breakup is painful for the parents and can be enduringly damaging for the children. There are, in short and quite uncontroversially, some significant harms associated with the breakdown of marriages.
How can marriage breakdown – and hence those harms – be avoided? Continue reading
