In this article, we present three necessary conditions for morally responsible animal research that we believe people on both sides of this debate can accept. Specifically, we argue that, even if human beings have higher moral status than nonhuman animals, animal research is morally permissible only if it satisfies (1) an expectation of sufficient net benefit, (2) a worthwhile-life condition, and (3) a no-unnecessary-harm/qualified-basic-needs condition. We then claim that, whether or not these necessary conditions are jointly sufficient for justified animal research, they are relatively demanding, with the consequence that many animal experiments may fail to satisfy them.

In this paper I ask how we should treat other beings in cases of uncertainty about sentience. I evaluate three options: (1) an incautionary principle that permits us to treat other beings as non-sentient, (2) a precautionary principle that requires us to treat other beings as sentient, and (3) an expected value principle that requires us to multiply our subjective probability that other beings are sentient by the amount of moral value they would have if they were. I then draw three conclusions. First, the precautionary and expected value principles are more plausible than the incautionary principle. Second, if we accept a precautionary or expected value principle, then we morally ought to treat many beings as having at least partial moral status. Third, if we morally ought to treat many beings as having at least partial moral status, then morality involves more cluelessness and demandingness than we might have thought.

This chapter discusses the relationship between animals, pandemics, and climate change. In the Anthropocene, human activity is increasingly responsible for harm in the world. For example, factory farming, deforestation, and the wildlife trade are all killing trillions of animals per year unnecessarily. They are also contributing to global threats such as pandemics and climate change. These global threats are, in turn, contributing to biodiversity loss, ecosystem collapse, and animal suffering, both directly and indirectly. In light of these impacts, we should reduce our use of animals as part of our pandemic and climate change mitigation efforts and increase our support for animals as part of our pandemic and climate change adaptation efforts, and we should do so holistically, structurally, and comprehensively.

According to our traditional conception of agency, most human beings are agents and most, if not all, nonhuman animals are not. However, recent developments in philosophy and psychology have made it clear that we need more than one conception of agency, since human and nonhuman animals are capable of thinking and acting in more than one kind of way. In this paper, I make a distinction between perceptual and propositional agency, and I argue that many nonhuman animals are perceptual agents and that many human beings are both kinds of agent. I then argue that, insofar as human and nonhuman animals exercise the same kind of agency, they have the same kind of moral status, and I explore some of the moral implications of this idea.

In this paper I examine several of the moral and political questions raised by new kinds of meat. I begin by discussing the risks and harms associated with industrial animal agriculture, and I argue that plant-based meat and cultured meat are promising alternatives to conventional meat. I then explore the moral, conceptual, social, political, economic, and technical challenges that stand in the way of widespread adoption of these alternatives. For example, whether or not we achieve widespread adoption will depend on whether or not we can persuade business and political leaders to see plant-based and cultured meat as an opportunity rather than as a threat. Finally, I consider several ways of meeting these challenges, and I argue that we must be very careful if we want to avoid the kinds of problems that other, similar technological innovations such as GMOs have faced.
