Histoire croisée, or as it is sometimes known in English, “entangled history”, deals with questions of comparison, reciprocity, and asymmetry. WernerMichaelZimmermannBénédicte, “Beyond comparison: Histoire croisée and the challenge of reflexivity”, History and theory, xlv (2006), 30–50. In another formulation, “Histoire croisée … asks that historians understand their categories of analysis as well as their objects of study, as ‘entangled products’ of [trans]national [inter-]crossings”. CohenDeborahO'ConnorMaura, “Introduction: Comparative history, cross-national history, transnational history — Definitions”, in Comparison and history: Europe in cross-national perspective, ed. by CohenDeborahO'ConnorMaura (New York, 2004), pp. ix–xxiv, p. xiv. Entangled history shares at least one important element with comparative methods and research into intellectual transfers: The will to go beyond the perspective of nation-centred history.

Among many measures of the admiration may be cited use of his portrait as a frontispiece for the twenty-second volume of the exhaustive, universal guide to the academic world, Minerva, Jahrbuch der gelehrten Welt, ed. by BeugelJ.LüdtkeG.

We reject the casual indictment of the historian Eustace Dockray Phillips: ” The difference between the age in which he [Sarton] grew up and the present time appears in his relations with the famous historian Henri Pirenne, who clearly had no high opinion of Sarton's lifelong occupation, and thought that the development of science had little to do with history proper. It may be remarked that the periods of history which chiefly occupied Pirenne were not those in which science had any important effect on events.” Phillips, reviewing George Sarton: De mens en zijn werk uit brieven aan vrienden en kennissen (Brussels, 1965), by Paul van Oye, in The British journal for the history of science, iii (1967), 397.

Marc Boone has recalled the opinion of Jan Dhondt, medievalist and founder of the Ghent seminar of contemporary history, that Henri Pirenne's greatness as a historian lies in his seminal scholarly role for two generations.

From the epistemological side of modernism, Peter Wagner has suggested that modern knowledge was: (1) “effective, pragmatic and performance-oriented” (2) “more comprehensive than the ‘old’ sciences”; (3) “more widely communicable” than pre-modern knowledge. Wagner, “Introduction to Part I”, in Transnational intellectual networks: Forms of academic knowledge and the search for cultural identities, ed. by CharleChristopheSchriewerJürgenWagnerPeter (Frankfurt am Main, 2004), 17–25, p. 25. This formulation would surely have been congenial to Denis Diderot in the eighteenth century, although the large volume coedited by Wagner focuses almost exclusively on the nineteenth and twentieth centuries.

In the Belle Epoque, Sarton most admired Henri Poincaré, and he wrote favourably about Paul Tannery, neither of them positivist. He also admired both the philosopher Emile Boutroux and Emile's son the mathematician Pierre Boutroux, a successor in the Comtean chair in history of science at the Collège de France; neither father nor son was a positivist.

Sympathy, certainly, but Sarton affirmed in the letter that he was no pure positivist, for his makeup was tempered by a mystical streak.

BrownHarcourt, “The Renaissance and historians of science”, Studies in the Renaissance, vii (1960), 27–42, for Sarton's minimization of science in the Renaissance in 1929, in contrast to Panofsky's views about the significance of Renaissance artists for science. George Sarton, “Science in the Renaissance”, in The civilization of the Renaissance, ed. by ThompsonJames Westfall (New York, 1929), 75–95. In Sarton's view, the Renaissance was “a halfway rest between two revivals”, the first from the eleventh century to the thirteenth century, and the second in the seventeenth century. Apart from excoriating the Renaissance humanists of Italy, whom he took to be hostile to “scientific enlightenment” (p. 93), he was nevertheless clear that the Florentine artists “not only raised their art to a higher level but prepared the creation of a new branch of mathematics” (p. 84), and he emphasized significant mathematicians and mechanicians, astronomers, and anatomists, culminating in Vesalius and Copernicus. Sarton generally saw science and art as two complementary endeavours deriving from a common creative urge, and before 1925 he maintained the view that he expressed in 1910: “I am one of those who think that the enterprise of science is an enterprise of art. I do not think it only, I sense it, with all my being, all my nerves tell me that…. I know that art and science are identical, just as I know that I exist. The two, when they are beautiful enough, produce the same enthusiasm, the same frenzy, the same sacred intoxication, the same rhythms, the same thrills.” Pyenson, Passion (ref. 14), 110.
