The Rejection of Continental Drift: Theory and Method in American Earth Science / Edition 1

by Naomi Oreskes

Overview

In the early twentieth century, American earth scientists were united in their opposition to the new—and highly radical—notion of continental drift, even going so far as to label the theory "unscientific." Some fifty years later, however, continental drift was heralded as a major scientific breakthrough and today it is accepted as scientific fact. Why did American geologists reject so adamantly an idea that is now considered a cornerstone of the discipline? And why were their European colleagues receptive to it so much earlier? This book, based on extensive archival research on three continents, provides important new answers while giving the first detailed account of the American geological community in the first half of the century. Challenging previous historical work on this episode, Naomi Oreskes shows that continental drift was not rejected for the lack of a causal mechanism, but because it seemed to conflict with the basic standards of practice in American geology. This account provides a compelling look at how scientific ideas are made and unmade.

Editorial Reviews

"Oreskes (Univ. of California, San Diego) argues that 'science is about how belief gets formulated,' and that the criteria used in the formulation of belief are historically contingent and play a significant role in constraining the boundaries of scientific knowledge in a cultural and social context. Using the history of evolution of the continental drift theory, she discusses how US earth scientists came to reject this theory in the 1920s and '30s because accepting the ideas supporting it would have forced them to change their methodological beliefs and valued forms of scientific practice. Oreskes utilizes the case of the history of continental drift to show that scientific methodology is diverse and evolves through time, and that the mechanics of scientific research and the context of discovery are important, just as the context of justification is important in evaluating the generation of scientific knowledge. . . . An exemplary resource. Recommended. All levels."—Choice

"With all their resources, American geoscientists do much of the world's best geology. Thus some of them may be embarrassed that their predecessors were so slow to embrace continental drift or convection currents in the mantle and were initially so resistant to the doctrines of plate tectonics. Although there must be historical reasons for this reluctance to accept mobilist doctrines, hitherto they have not been examined in detail. Now Naomi Oreskes has accomplished the task in The Rejection of Continental Drift. Based on extensive archival research and Oreskes's studies over the past 20 years, her admirably clear and well-illustrated account is scientifically, philosophically, historically, and sociologically well-informed. All is achieved without recourse to esoteric detail or any mathematics: she is after concepts."—Science

"During the 1920s and '30s, prominent American geologists were generally opposed, sometimes virulently so, to continental drift, a new theory proposed by Alfred Wegener. On the opposite side of a furtively widening transatlantic schism, earth scientists were inclined to explore the idea, or at least to regard it with more muted skepticism. Wegener's original 'theory' was incomplete and mechanically unsound, and some of his European colleagues actually bent their effort toward developing physical models in support of drift. After all, the theory did summarize a set of observations that hinted at a broader vision of geological mapping than was currently in vogue. However, Americans appear to have been committed to demonstrating the impossibility of drift. Naomi Oreskes has carefully sifted the archival ashes of the early stages of this conflagration, producing an analysis of scientific practice that challenges previous accounts of the drift controversy."—American Scientist

"On April 7, 1998, there was a note in Eos by David Stern that included a perceptive and amusing quotation from Teddy Bullard on the question, which has been recently reached something of a culmination in an important new book, The Rejection of Continental Drift, by Naomi Oreskes and published by Oxford in 1999."—EOS
