Abstract

According to Autumn Fiester, the Presumption of Restraint—the thesis that an application of biotechnology to an animal is unethical unless backed by morally compelling reasons—is justified by five ethical claims. In this commentary, I explore the relevance of what Derek Parfit has dubbed the Non-Identity Problem for the implications of one of these claims, the Animal Welfare Claim. I conclude that while the Animal Welfare Claim condemns the alteration of founder animals in ways that are bad for them when there is no important human or animal health benefit in the offing, it fails to condemn the alteration of animals in the context of important research projects, even if the alteration causes some animal suffering, and, given the Non-Identity Problem, it fails to condemn the subsequent creation of animals bred from the founders, so long as the subsequent animals have a life worth living.
