Abstract

Frey sets the challenge for the other authors: to explain why, morally, no humans can be subject to the kinds of experiments that animals are subject to and to explain how researchers can reliablyuse animal models to understand and cure human disease. He thinks that the first challenge has not been met; the second challenge is, unfortunately, not directly addressed in this book. Adrian Morrison states that he “abhors” positions like Frey’s, Peter Singer’s and Tom Regan’s. He asserts that all “human beings stand apart in a moral sense from all other species” and that all are worthy of “special consideration”. Regrettably he fails to defend his view by identifying the morally-relevant characteristics that all humans possess and all animals lack that might make his claim true. That omission prevents him from rationally criticizing opposing views
