Wild animal reproduction poses an important moral problem for animal rights theorists. Many wild animals give birth to large numbers of uncared-for offspring, and thus child mortality rates are far higher in nature than they are among human beings. In light of this reproductive strategy – traditionally referred to as the ‘r-strategy’ – does concern for the interests of wild animals require us to intervene in nature? In this paper, I argue that animal rights theorists should embrace fallibility-constrained interventionism: the view that intervention in nature is desirable but should be constrained by our ignorance of the inner workings of ecosystems. Though authors sometimes assume that large-scale intervention requires turning nature into an enormous zoo, I suggest an alternative. With sufficient research, a new form of gene editing called CRISPR promises to one day give us the capacity to intervene without perpetually interfering with wild animals’ liberties.

G. A. Cohen’s claim that fundamental principles are ‘fact-insensitive’ has not received an especially warm welcome from the philosophical community. While some philosophers have expressed doubts about the plausibility of his claim, others have complained that even if his thesis is true, it is also relatively insignificant. In my paper, I argue that the fact-insensitivity thesis, if true, provides considerable support for value pluralism, and is thus of interest for that reason. Though Cohen himself assumes a plurality of fundamental principles, he never argues that the fact-insensitivity thesis supports this assumption. One of my paper’s aims, then, is to fill an argumentative gap in Cohen’s meta-ethical framework.

G.A. Cohen is well known within contemporary political philosophy for claiming that the scope of principles of justice extends beyond the design of institutions to citizens’ personal choices. More recently, he’s also received attention for claiming that principles of justice are normatively ultimate, i.e., that they’re necessary for the justification of action guiding principles but are unsuitable to guide political practice themselves. The purpose of this paper is to explore the relationship between these claims as they’re applied in criticism of John Rawls. It argues that ascribing normative ultimacy to justice entails its application to personal choice. However, it also argues that if Cohen’s right about Rawls’s difference principle being regulatory rather than ultimate, then his earlier claim that Rawls must extend it to personal choice on pain of inconsistency is refuted
