Ending Child Marriage in the UK

On 16 June 2021, Sajid Javid MP introduced a Private Members’ Bill into the UK Parliament to raise the minimum age of marriage in England, Wales and Northern Ireland to 18. This follows earlier attempts by Pauline Latham MP to criminalise child marriage. Currently, teenagers aged 16-18 may marry with their parent’s consent (in Scotland, they can already marry without parental consent). From an international law perspective, this Bill would end child marriage in the UK (which the international community has pledged to stop by 2030). Philosophically, it raises interesting questions about what decisions people should be permitted to make at 16; and the balance between maximising people’s options, and protecting a small number from significant harm.

We have a duty to pay for kidneys

In this post, Aksel Sterri discusses their recent article in Journal of Applied Philosophy on the ethics of a government-monopsony market in kidneys.


Two million people suffer from kidney failure worldwide. They either die or live difficult lives on dialysis while waiting for kidneys to become available for transplant, from dead or living donors. Our failure to meet the need for kidney transplants is a moral failure that calls for a change in how we procure kidneys. In a recent paper, I argue members of nation states have a collective duty to pay kidney donors to ensure that people in need receive a new kidney.

A Criminal Law for Semi-Citizens

In this post, Cristián Irarrázaval Zaldívar and Ivó Coca-Vila discuss their recent article in Journal of Applied Philosophy on how to legitimate punishment in the context of varying forms of citizenship.


Ask yourself why an English court can legitimately punish an Indonesian who committed an offence in Japan but now lives in the UK, or a Spanish judge can punish a young Senegalese criminal offender who, after months crossing through Africa, enters Spain illegally and subsists in absolute hardship hidden from state authorities. Probably your answer would be something along the lines that punishment is necessary to prevent harm. Indeed, that is how most criminal law scholars respond. However, among contemporary authors, it is increasingly common to assert that the criminal law of a given state should be applicable only to those who, at the time of the commission of the offence, had some kind of political bond with it, namely, to those who belonged to the polity as “citizens”. In our recent article, we explain why the advantages of this approach outweigh the downsides, at least as long as we take seriously the fact that citizenship is not all-or-nothing, but comes in degrees.

On our special relationship with future generations

In this post, Charlotte Unruh discusses their recent article in Journal of Applied Philosophy on the basis of our duties to future generations.


Do you sometimes picture future generations as strangers in a faraway galaxy? Strangers who we know little about, aside from the fact that our actions can affect their lives?  In a recent paper, I argue that there is a crucial difference between (very) remotely living strangers and future generations. There is a special relationship that obtains between present and future people. We bring future generations into existence. I suggest that this gives rise to special responsibilities to embed long-term thinking in politics, business, and society.

What Epistemic Profiles Should We (Not) Foster?

It is often said that the main task of teachers is to foster learning. But what kind of learning? What knowledge can we hope to attain through such learning? And what kinds of people should children aspire to become in the process? We imagine that fostering learning in the right way would ensure not only that adults lead flourishing lives, but that they can help others in acquiring knowledge. As epistemologists show, some intellectual virtues are other-regarding, meaning that individuals can and should affect others in their knowledge acquisition and intellectual flourishing; such is, for instance, the drive to discover socially relevant findings, or honesty and integrity in communicating information (Turri and Alfano, 2017).
