“Eating and Being is a history of dietetics, and of the ideas about eating that succeeded it, all the way up to the unpoetic calorie. Shapin is an eminent historian of science whose work has taught us much about the social worlds in which scientific knowledge was created, and he argues here that thinking about food is also a way of thinking about some of the most fundamental categories of human physiology, personality, and morality. . . . Shapin traces the slow and uneven transformations in the ways people imagined their bodies to work, how food made flesh; in his telling, this isn’t a story of radical change but of ‘layered pasts, a surface through which supposedly past sentiments intermittently intrude, one in which some elements of the past were never completely submerged.’”
