Abstract
. . Tom Beauchamp and David DeGrazia's principles do improve upon the 3Rs which don’t mention the need for benefits from animal experimentation, the need to compare these benefits to animal harms, and provide no hard limits on experimentation.
However, they present their principles as “useful” for people engaged in animal research and as a “philosophically sound” (p. 4) framework for a new ethic for animal research. Regrettably, I have doubts about both these overall claims and so am pessimistic about the book.
