Abstract

Thomas Kuhn was not only the greatest historian of science but also one of the most influential philosophers of the twentieth century. Faced with such a significant character, Giuseppe Giordano has decided to focus on Kuhn “the philosopher,” touching on the historian only indirectly. The book is roughly divided into two parts. The first one is devoted to a reconstruction of the genesis of Kuhn's most important ideas, focusing in particular on the essay “The Essential Tension” and on The Structure of Scientific Revolutions. In the second part Giordano considers the reception of Kuhn's work within the philosophy of science community. Since the philosophical debate is almost entirely a post‐Structure phenomenon, the narrative proceeds more or less in chronological order, covering Kuhn's career from the beginning to the end. The story unfolds almost entirely in the realm of ideas, ignoring institutional matters such as Kuhn's role in the creation of a community of professional historians of science or his time as president of the Philosophy of Science Association.The better part of the book is the first. Here Giordano tells us how Kuhn turned from physics to the history of science and, most important, how the concept of “paradigm” evolved from a pedagogic device to a pathbreaking philosophical idea. He also sketches the intellectual background to Kuhn's work, especially the received views on science and on the role of history embodied in the logical positivism of the 1950s. Unfortunately, the author does not make use of recent work on Kuhn, Carnap, and the neopositivists by Peter Galison, Michael Friedman, and others. As a result, the contraposition between the “old” and the “new” philosophy of science is a fairly conventional and dated one. Developments in the historiography of science in the last two decades are also ignored: one would have liked to read something on Kuhn's influence on the new sociology of science, the birth of the micro history of science as a reaction to Kuhn's macro approach, and so forth.But of course no author can discuss everything, and Giordano has explicitly decided to focus on the relationship between Kuhn and the philosophers of his time. Chapter 3 deals with the controversy between Kuhn and Karl Popper. Giordano argues that whereas Popper never really questioned his own theses, Kuhn benefited from the debate, which prompted some significant changes in his position. In this chapter and the following one , Kuhn's thought is presented in its dynamic evolution, as he adjusted and reacted to criticism. In both chapters Kuhn is set at center stage, with the other characters playing supporting roles.The last chapter discusses Kuhn's “mature” views on theory change and scientific progress. It is a pity that nowhere in the book are we provided with a rigorous formulation of crucial concepts such as “progress” and “scientific rationality.” This is the main defect of the book, the philosophical depth and rigor of which is sometimes less than satisfactory. Other examples are a confusion between scientific realism and the correspondence theory of truth , a sloppy formulation of the problem of induction , and the lack of a serious discussion of the Duhem‐Quine problem . Because of these problems, Giordano's book is valuable chiefly as a concise summary and discussion of the overall significance of Kuhn's philosophical work. The commentary is frequently interrupted by long quotations from Kuhn's texts, and the footnotes also quote widely from the secondary literature . This makes Giordano's book a peculiar piece of work, rather like a conflation of a textbook and a Kuhnian anthology.It must be recognized that to write yet another book on Kuhn is a challenging task. Kuhn's work has been dissected, criticized, and interpreted a number of times, and a truly novel analysis would require a truly novel approach. Other scholars have stretched the interpretation of known texts and facts until they have become “new” texts and facts. Giordano does not aim to be controversial and admirably abstains from such flamboyant exercises. However, he does not pursue the other route either: that of digging deeper into the past in order to discover something genuinely novel. A new book on Kuhn should be based, at the very least, on serious archival research in Kuhn's papers at MIT, and Giordano has not done that. Furthermore, he relies on a relatively small fraction of Kuhn's published writings, invariably the most widely known and celebrated ones. It is not surprising, then, that he ends up with a very familiar picture of Thomas Kuhn and his place in twentieth‐century philosophy of science
