"Is an animal used in scientific research an 'it' or a 'who'? This is the core theme of this gentle but powerful book. Gluck, a former primate researcher trained by Harry Harlow at the University of Wisconsin in the 1970s, who later transitioned to a career in clinical psychology at the University of New Mexico, offers a brief in favor of a massive reduction in our use of animals in experimental research, especially in psychology (though details on how precisely this is to be done are scant). . . . This brief, however, does not come in the form of a sustained philosophical argument a la Peter Singer or Tom Regan. It is not a work of formal ethics leading to a battery of 'shoulds.' Instead, the book is a memoir. . . . Artfully crafted insights. . . . An engaging narrative. The memoir format makes an important contribution to the history of psychology, offering firsthand recollections of Harry Harlow and other researchers at the University of Wisconsin. Gluck, like Browne, also has an eye--trained by scholarship in science studies--for how institutions, personalities, facilities, and other 'external' factors shape scientific knowledge production. . . . A brilliant, forceful meditation, generous in its self-reflexivity, compassionate toward animals and scientists alike, and profound in its insights."
