Recent scientific developments suggest that it may become possible to create viable human gametes from human stem cells. It has been suggested that this will lead to the development of a range of new fertility treatments as well as new strands of research. More speculatively, some have argued that it may

• Allow the radical enhancement of human reproductive capabilities, for example, by allowing same-sex couples or post-menopausal women to have genetically-related offspring
• Provide new means of creating ‘designer babies’, for example, by easing constraints on the number of embryos that can be produced in IVF.

In a feature article forthcoming in the Journal of Medical Ethics, Robert Sparrow discusses the possibility that stem cell technologies might be used to facilitate what he calls ‘in vitro eugenics’; the deliberate and selective breeding of multiple generations of human embryos in vitro. The Editors of the Journal of Medical Ethics now invite submissions for a special issue addressing the ethical questions raised by Sparrow’s paper and by stem cell-derived gametes more generally.

There is another case in the news where someone is making a legal bid to allow his doctors help him to die. These cases are always heartrending. It’s a cliché that hard cases make bad law. But it’s a cliché because it’s true. If we look at individual cases, there are often very strong grounds… Read More »Thoughts on assisted suicide

How strongly wedded are people to their political preferences? The received wisdom amongst political journalists and pollsters is that most people can be counted on to vote for one major party or another, and only a relatively small percentage of people swing elections. It is these people – swinging voters, as they called in Australia – who decide elections. At very least, as an election approaches most have made up their mind and can’t be persuaded to shift.

Suppose most people are committed to a major party, at least in the days preceding an election.  Is this a matter of policy agreement or of something more like identification or tribal allegiance? A recent paper casts some light on this question, and along the way suggests that people might be more open to shifting allegiances than we might have thought, at least if approached in the right way.Read More »Politics as tribal allegiance

To what extent do self-interest and altruism conflict? In my latest Quartz article, I suggest that they conflict less than you might think.

Last year, Julian Savulescu of the Uehiro Centre for Practical Ethics here at Oxford debated Robert Sparrow of Monash University on the issue of using techniques like embryo selection to ensure one’s children have the best life possible.  Savulescu has notably defended not only the permissibility but the obligation to select for the best children, while Sparrow has been more critical of enhancement via embryo selection.  The transcript of their debate is now available, and their exchange helps clarify a key source of disagreement between proponents and critics of embryo selection – whether parents should be maximizing their children’s well-being, or simply giving them a good enough life.  At its core, the debate is less about the intricacies of new technologies like preimplantation genetic diagnostics (PGD) and more about the ethics of parenting.  I’ll summarize some of the key points of the debate below, but I encourage readers to have a look at the transcript to get a sense for how the dialectic plays out as well as how each interlocutor deals with a wide array of objections.Read More »Julian Savulescu and Robert Sparrow debate the ethics of designer babies
