Derek Parfit, who died in 2017, is widely believed to have been the best moral philosopher in well over a century. The twenty new essays in this book were written in his honour and have all been inspired by his work - in particular, his work in an area of moral philosophy known as 'population ethics', which is concerned with moral issues raised by causing people to exist. Until Parfit began writing about these issues in the 1970s, there was almost (...) no discussion of them in the entire history of philosophy. But his monumental book 'Reasons and Persons' (1984) revealed that population ethics abounds in deep and intractable problems and paradoxes that not only challenge all the major moral theories but also threaten to undermine many important common-sense moral beliefs.

Many of us believe that if some acts wrongly out of culpably ignorance, they are morally blameworthy to some degree. I offer a defense of this view against the powerful "Liberal Challenge" to the position. My defense proceeds by arguing that facts about a given agent's quality of will can play a different explanatory role in the larger theory of blameworthiness and the structure of exculpation than is often assumed.

It's been argued that better- than is non-transitive – that there are some value bearers for which better- than fails to generate an acyclic ordering. Michael Huemer has offered a powerful objection to this view, which he dubs ‘The Dominance Argument’. In what follows, I consider the extent to which there is a plausible response to be made on behalf of those who hold that better- than is non-transitive. I conclude that there is.

The phenotypic variation found in domesticated plants and animals is striking, so much so that Darwin used it to illustrate the power of selection to effect change. Recent developments in genomics technologies are leading to dramatic progress in elucidating the genetic changes that occur during domestication. The Genetics Society Autumn Meeting on the genetics of domestication took place in November 2004 at the Royal Society in London, and was organised by Helen Sang (Roslin Institute, UK) and Jonathan Jones (John Innes (...) Centre, UK). The meeting brought together many of the leading researchers on livestock and crop domestication and provided a timely and exciting account of recent progress in the field.
