Since science is the defining intellectual enterprise of our age, it would seem worth understanding who the scientist is. This is the task Steven Shapin takes on in his latest book, The Scientific Life. Shapin’s book represents something of a departure from his previous efforts. The Franklin L. Ford Professor of the History of Science at Harvard University, Shapin is perhaps best known for two works on seventeenth-century science, A Social History of Truth (1994) and The Scientific Revolution (1996). He is also coauthor, with Simon Schaffer, of Leviathan and the Air-Pump (1985), a fascinating account of debates between Robert Boyle and Thomas Hobbes over the legitimacy and proper interpretation of experimental manipulation in science. In his new book, Shapin ventures beyond the strict boundaries of the history of science. While he spends some time on the evolution of the scientific vocation, he’s also concerned with how scientists live and work now.
