1. David Baltimore, a microbiologist who later received the Nobel prize, appeared on public television in 1974 to discuss Frederick Wiseman's controversial documentary movie on the use of primates in scientific experiments at Yerkes Primate Research Center. Other scientists and moral philosopher Robert Nozick also participated in the program. Nozick asked the scientists whether the fact than an experiment would kill hundreds of animals is ever regarded by them as a reason for not performing it.

Chapter 2). Some people find the Cartesian ring of these words chilling. Others would accept these remarks uncritically as merely descriptive of the passion of discovery. In any case, their truth reveals the all-too-real problems that investigators face in remaining always sensitive to what should be overriding humane demands. What is clear is that Bernard was sensitive to the moral issues raised by animal experimentation, that he cannot be blamed for not using anesthetics for his curare work because no one knew the action of curare at that time, and that he did use anesthetics within months of the first demonstration of the pain-killing effects of ether.

By contrast, it was not until 1963 that the first French legislation controlling animal experiments was passed. Disenchanted with the compromise, the nineteenth-century antivivisectionists immediately withdrew their support for the law. Frances Power Cobb, the leading antivivisectionist, said that the effect of the 1876 law would be to anesthetize the public, not the animals! This pattern of antivivisectionists' withdrawal of support of reform legislation has been repeated over and over again since then.
