Enno Heeren Dirksen (1788–1850) was one of several mathematicians originating from Eastern Frisia at the end of the eighteenth century to acquire prominence in neohumanist reformed Prussia. While striving—like so many of his contemporaries—for more rigour in the foundations of calculus, his work is significant due to his unusual emphasis on the semiotic aspects of the basic concepts. As a clear-sighted propagator of Cauchy's conceptual innovations in Germany, his achievements in improving sign expressions of such concepts enabled him to (...) clarify hitherto not differentiated multiple limit processes—although less successfully in constructive concept formation itself. The contribution is based on the analysis of Dirksen's published texts and on the numerous texts which remained drafts for his projected voluminousOrganon der gesamten Analysis. (shrink)

SummaryThe foundations of modern international thought were constructed out of diverse idioms and disciplines. In his impressive book, Foundations of Modern International Thought, David Armitage focuses on the normative idioms of natural law and political philosophy from the Anglophone world, from Hobbes and Locke to Burke and Bentham. I focus on parallel developments in the empirically-oriented disciplines of history and historiography to trace the emergence of histories of the states-system in the Italian- and German-speaking worlds, from Bruni and Sarpi to (...) Pufendorf and Heeren. Taking seriously Armitage's remark that ‘the pivotal moments in the formation of modern international thought were often points of retrospective reconstruction’, I argue that the historical disciplines supplied another significant intellectual context in which the modern world could be imagined as ‘a world of states’.
