Plausibility and Same-Sex Marriage

In philosophical discussions, we bring up the notion of plausibility a lot.  “That’s implausible” is a common form of objection, while the converse “That’s plausible” is a common way of offering a sort of cautious sympathy with an argument or claim.  But what exactly do we mean when we claim something is plausible or implausible, and what implications do such claims have?  This question was, for me, most recently prompted by a recent pair of blog posts by Justin Weinberg over at Daily Nous on same-sex marriage.  In the posts and discussion, Weinberg appears sympathetic to an interesting pedagogical principle: instructors may legitimately exclude, discount or dismiss from discussion positions they take to be implausible.*  Further, opposition same-sex marriage is taken to be such an implausible position and thus excludable/discountable/dismissable from classroom debate.  Is this a legitimate line of thought?  I’m inclined against it, and will try to explain why in this post.**  Continue reading

Risky Giving

I highly recommend Leif Wenar’s essay “Poverty Is No Pond” – especially to those not yet familiar with, but interested in, the empirical complexities involved in giving to overseas poverty-fighting charities.  Wenar’s main aim in his essay is to criticize Peter Singer’s 2009 book The Life You Can Save for (i) being overly optimistic about the quality of information available on the effects of giving to various charities, and (ii) failing to emphasize that every charitable donation also comes with some risk of harming people living in extreme poverty.  I’ll only briefly address (i), and then turn to and focus primarily on (ii).

What are the ethics of using brain stimulation technologies for ‘enhancement’ in children?

New open access publication: announcement:

In a recently published article, Hannah Maslen, Roi Cohen Kadosh, Julian Savulescu and I present an argument about the permissible (and not-so-permissible) uses of non-invasive brain stimulation technology in children. We consider both children who may be suffering from a specific neurological disorder, for whom the stimulation is intended as a ‘treatment’, and those who are otherwise healthy, for whom the stimulation is intended as ‘enhancement’. For the full article and citation, see here:

Optional whether to give, therefore optional where to give?

You might think that if it’s not wrong not to donate to charity, then it’s not wrong to give to whatever particular charity you choose (as long as no harm is done).  I’m going to argue against this view.  Very often, it is wrong to give to an ineffective charity, even when it’s not wrong not to give at all.

Saving administration costs or saving lives?

By Lucius Caviola & Nadira Faulmüller

Imagine a car company advertising as follows: “90c of any dollar you pay for your car goes directly to building cars. Only 10% of our expenses go into planning, designing, and advertising them.” Such a campaign strategy would seem patently bizarre; when buying a product few of us are interested in how much went into administration, all we care about is what we get for our money. Overhead ratio (the proportion of money going into administration) is irrelevant; only cost-effectiveness matters.

This common sense approach to purchasing goods or services does not seem to translate into the non-profit sector, however. Consider the following advertisement by the organisation CARE:  “More than 90 percent of our expended resources – among the highest of all philanthropic organisations – support our poverty-fighting projects around the world. Less than 10 percent of expended resources go toward administrative and fundraising costs.” Continue reading

People and charitable causes are importantly different things

Like Prot – the lovable character played by Kevin Spacey in the underrated movie K-PAX – you’re an intelligent benevolent extraterrestrial who has just been beamed to Earth.  Sadly, unlike Prot, you have no return ticket.  The good news for you is that just moments after hopping off of your beam of light, you found a briefcase stuffed with $3 million.  Being benevolent, and having concern for the inhabitants of Earth, you decide to give nearly all of this money to charity.  Being completely new to the planet, however, you do not yet have any special concern for anyone here – no friends, no loved ones.  Having this equal concern for everyone, you want simply to do the most good possible, and so you decide to give this money to the most cost-effective charities you can find.

Exit science fiction scenario.

One important difference between each of us and this Prot-agonist is that we do have friends and loved ones; we have rich shared histories with them, we care deeply about them, and, crucially, the level of concern we have for them is not on a par with the general concern we have for strangers.  If your fiancé were drowning in a lake to your north, and ten strangers were drowning in a lake to your south, and you could either rescue the one to your north or instead the ten to your south (but not all eleven!), you’d probably head north.  Whether this constitutes morally good behavior on your part is a matter of controversy among contemporary ethical theorists.  But let’s assume the commonsense view that it’s not wrong of you to save your fiancé over the ten others.  This degree of special partial concern is, we’ll suppose, justified.

On the Supposed Importance of Cultural Traditions for Whaling Practice

Today is the first day of the 65th meeting of the International Whaling Commission (IWC). The commission, set up in 1946 to ensure the proper conservation of whale stocks and assist in the orderly development of the whaling industry, determines how many, which, and for what purpose, whales can be killed. The meeting beginning today is important because it will re-open discussion about Japan’s right to whale for the purposes of conducting scientific research. This past March, Japan lost this right because its findings were deemed to be of little use, and it was clear that the “scientific” nature of the killings were only a ruse. The IWC imposed a moratorium on commercial whaling in 1982, but still allows that the meat of whales killed for scientific purposes could be sold for profit. The Japanese whaling industry exploited this fact in order to sustain what was effectively a commercial whaling industry. Whales were killed in the name of scientific research, and then the meat was sold commercially. The International Court of Justice (ICJ) ruled that this violated the requirement imposed by the IWC that the killing of whales be only “for the purposes of scientific research.”

Of the many arguments deployed by the Japanese authorities concerning their right to whale, one is of particular interest to me; namely, that whaling constitutes an important aspect of Japanese culture, and thus ought to be permitted to continue.[1] In what follows, I claim that arguments based on cultural tradition alone are insufficient to generate a right to whale. In cases where the species of whale being killed is not endangered, then (on the condition that the method of whaling used is sustainable) no further reasons need be given in order to defend the practice. Whaling will be just like eating meat,[2] and arguments from cultural tradition will be superfluous. However, if the species of whale is endangered, then whaling is permissible only in cases of practical necessity. Continue reading

Taking Rape Allegations Seriously: How Should We Treat the Accused?

Last week, the Crown Prosecution Service announced that it would not pursue further action against Oxford Union president Ben Sullivan, due to insufficient evidence arising from an investigation into the two accusations of rape and attempted rape made against him. In early May, Sullivan was arrested and released on bail, prompting a chaotic six-week period for the Union as the Thames Valley Police investigated the claims made against him. After Sullivan refused to resign, a number of high-profile speakers, including the UK director of Human Rights Watch, the Interpol secretary-general, and a Nobel Peace prize winner, pulled out of their speaking commitments as part of a larger boycott of Union events.

In an open letter (which has since been taken down) calling for the boycott, students Sarah Pine, who is Oxford University Student Union’s Vice President for Women, and Helena Dollimor wrote, “Remaining in his presidency continues to offer prestige and power to someone who is being investigated for rape. This undermines the severe nature of allegations of sexual offences.” In contrast, Oxford professor A.C. Grayling penned a response to the letter refusing to cancel his scheduled talk at the Union, noting, “I simply cannot, in all conscience, allow myself to act only on the basis of allegations and suspicions, or of conviction by the kangaroo court of opinion, or trial by press…” In this post, I look at the spectrum of responses in the wake of Sullivan’s arrest, of which these two examples represent the poles. More broadly, I consider how we ought to respond – both as individuals and a society – when those in positions of power are accused of rape or other sexual offences. Continue reading

When the poison is the antidote: risky disaster research

A recent report by Lipsitch and Galvani warns that some virus experiments risk unleashing global pandemic. In particular, there are the controversial “gain of function” experiments seeking to test how likely bird flu is to go from a form that cannot be transmitted between humans to a form that can – by trying to create such a form. But one can also consider geoengineering experiments: while current experiments are very small-scale and might at most have local effects, any serious attempt to test climate engineering will have to influence the climate measurably, worldwide. When is it acceptable to do research that threatens to cause the disaster it seeks to limit?

“The Medicalization of Love” – call for peer commentaries – DUE SEPT 1


The paper, “The Medicalization of Love” by Brian D. Earp, Anders Sandberg, and Julian Savulescu, has been accepted for publication at the Cambridge Quarterly of Healthcare Ethics. Scholars interested in submitting a short reply paper or peer commentary are encouraged to contact the editor, Tomi Kushner, at

The final deadline for commentaries/ papers is September 1st. The abstract for the paper is below; the accepted manuscript is available at this link. Inquiries to the editor should be sent as soon as possible.


Pharmaceuticals or other emerging technologies could be used to enhance (or diminish) feelings of lust, attraction, and attachment in adult romantic partnerships. While such interventions could conceivably be used to promote individual (and couple) well-being, their widespread development and/or adoption might lead to “medicalization” of human love and heartache—for some, a source of serious concern. In this essay, we argue that the “medicalization of love” need not necessarily be problematic, on balance, but could plausibly be expected to have either good or bad consequences depending upon how it unfolds. By anticipating some of the specific ways in which these technologies could yield unwanted outcomes, bioethicists and others can help direct the course of love’s “medicalization”—should it happen to occur—more toward the “good” side than the “bad.”

Here is the link to the accepted manuscript.
