ONE OF THE MOST REMARKABLE DEVELOPMENTS IN the world of scholarly letters in the last generation, and especially since the end of the late War, has been the growth of the study of the history of science both as a professional historical discipline and among the interests of the general reader. Considering how science has quietly come to take a central position in our culture this is perhaps not surprising; some knowledge of the history of science has become unavoidably part of the acquisition of historical awareness. It is precisely the period covered by this book that has attracted perhaps the most attention, and it is because of the interest shown in the original edition that it is now being re-issued.
