Author and Context
Sprache und Verkehr (“Language and Traffic,” or more idiomatically “Language and Communication”) is a work by Wilhelm Ostwald (1853–1932), the German physical chemist, philosopher, and organizer of intellectual life who won the Nobel Prize in Chemistry in 1909 for his work on catalysis, chemical equilibrium, and reaction velocities. Although Ostwald’s scientific reputation rests on the foundational role he played, alongside Jacobus van ‘t Hoff and Svante Arrhenius, in establishing physical chemistry as a discipline, the second half of his life was increasingly devoted to a broad program of cultural, philosophical, and organizational reform. It is to this later, reformist phase of his career that a work with the title Sprache und Verkehr belongs.
Ostwald’s mature outlook was governed by two interlocking commitments that recur throughout his non-chemical writings. The first was “energetics” (Energetik) — his conviction that energy, rather than matter, was the fundamental category of nature, and that human culture and conduct could be analyzed and improved by attention to the efficient use of energy. From this he derived what he called the “energetic imperative”: the injunction not to waste energy but to make the most productive use of it. The second commitment was to the rationalization and organization of intellectual work on an international scale. Ostwald believed that science and civilization suffered from enormous, avoidable friction and duplication of effort, and he threw himself into projects designed to reduce that waste — among them standardized formats for paper and publications, the reform of scientific communication, and the promotion of an international auxiliary language.
The German word Verkehr in the title carries a wider meaning than the English “traffic”: it denotes intercourse, communication, exchange, and commerce between people. The pairing of Sprache (language) and Verkehr therefore signals Ostwald’s characteristic concern with language considered not as an object of aesthetic or historical contemplation but as an instrument of human exchange and cooperation — a piece of communicative infrastructure whose efficiency could be measured, criticized, and improved.
Ostwald and the Movement for an International Language
The single most important background to Sprache und Verkehr is Ostwald’s active engagement with the movement for a planned international auxiliary language. In the first decade of the twentieth century Ostwald became one of the most prominent scientific champions of the idea that the multiplicity of natural languages was a serious obstacle to the progress of science and to international understanding, and that a constructed, regular, easily learned auxiliary language could remedy it. He was associated with the efforts of the Delegation for the Adoption of an International Auxiliary Language, and after the deliberations that led, around 1907, to the reformed language known as Ido (a modified derivative of Esperanto), Ostwald lent his considerable prestige to that cause. His involvement placed him among a group of scientists and intellectuals — including the mathematician Louis Couturet and others — who saw a world language as a natural companion to the internationalization of science.
For Ostwald this was not a linguistic hobby detached from his other convictions but a direct application of his energetic and organizational philosophy. The labor expended in learning multiple foreign languages, the losses caused by mistranslation and mutual incomprehension, and the fragmentation of scholarly literature across mutually unintelligible tongues all represented, in his eyes, a colossal squandering of intellectual energy. A rational, regular auxiliary language promised to reduce that waste and to accelerate the circulation of ideas across national boundaries. Sprache und Verkehr is best understood as an expression of this program: a consideration of language precisely in its function as a medium of communication and exchange, and of how that function might be discharged more efficiently.
Ostwald’s concern with international communication was of a piece with his other standardization efforts. He founded and supported the institute known as “Die Brücke” (The Bridge), dedicated to the organization of intellectual work and the systematic ordering of knowledge, and he campaigned for uniform standards in publishing and documentation. Within this constellation of activities, the reform and standardization of language occupied a central place, since language is the primary carrier of all other intellectual exchange.
Subject and Themes
Consistent with its title and with Ostwald’s known preoccupations, Sprache und Verkehr treats language as a social and practical phenomenon oriented toward communication. Its characteristic concerns are those Ostwald returned to repeatedly in his writings on the subject: the role of language in binding a community together and enabling cooperation; the burdens and inefficiencies imposed by linguistic diversity, especially in an increasingly international scientific and commercial world; and the case for a deliberately constructed, regular, and neutral auxiliary language to serve as a common medium alongside the national tongues.
The work reflects Ostwald’s tendency to approach cultural questions with the outlook of a natural scientist and organizer. Rather than dwelling on the literary, aesthetic, or nationalist significance of particular languages, he emphasizes measurable considerations of effort, learnability, and utility — the “economy” of communication. In this respect Sprache und Verkehr aligns with the broader current of early-twentieth-century thought that treated communication as a problem of efficiency and international organization, and it shares the optimistic, technocratic confidence, typical of Ostwald, that rational reform guided by scientific principles could improve institutions that had grown up by historical accident.
Place in Ostwald’s Work and Significance
Sprache und Verkehr belongs to the large body of popular, philosophical, and reformist writing that Ostwald produced after he largely withdrew from laboratory research and academic teaching in the early years of the twentieth century. During this period he was extraordinarily prolific as an author and lecturer, publishing on the philosophy of nature, on monism (he was for a time a leading figure in the German Monist League), on the theory of color, on the organization of science, and on the psychology and biography of great scientists. His writings on international language and on the standardization of intellectual work form a coherent subset of this output, and Sprache und Verkehr takes its place among them as a contribution to his campaign for more efficient international communication.
The significance of the work lies less in any technical linguistic innovation than in the fact that a scientist of Ostwald’s international standing devoted serious attention to the question of a world auxiliary language and integrated it into a comprehensive vision of cultural rationalization. His advocacy helped lend scientific respectability to the international-language movement at a moment when it was seeking recognition beyond the circle of its original enthusiasts. At the same time, the work exemplifies the confidence — and the limits — of the pre-1914 internationalist and technocratic mentality, which held that the frictions of human intercourse could be systematically engineered away. The First World War and the subsequent history of the twentieth century dealt harshly with such hopes, and the constructed international languages that Ostwald championed never achieved the universal adoption he anticipated. Nonetheless, his engagement with language as communicative infrastructure remains a characteristic and revealing episode in the intellectual biography of one of the founders of physical chemistry, and Sprache und Verkehr is a document of that engagement.
