ABSTRACTTo some extent, the early twentieth century revival of universal languages was the work of logicians and mathematicians. Pioneers of modern logic such as Frege, Russell and Peano wanted to overcome the diversity and deficiencies of natural languages. Through the rigour of formal logic, they aimed at providing scientific thinking with a reliable medium free from the ambiguity and inconsistencies of ordinary language. This article shows some interconnections between modern logic and the search for a common tongue that would unite (...) scientists and people of all nations. The French mathematician and philosopher Louis Couturat is a key figure in understanding the interplay between these two movements. Through his work in composing the Ido language as an alternative to Esperanto, Couturat gave a new life to the Leibnizian idea of a universal characteristics. In addition, his multifaceted work provides a valuable insight into some political implications of early analytic philosophy. (shrink)

This contribution examines the scientific background of Latino sine Flexione (LSF), an international auxiliary language constructed by Peano. LSF is part of a larger linguistic movement resulting from new technologies that accelerated globalisation. Science is a major driving force behind the international auxiliary language movement, both for creating an increased need for international contacts and for lending its data and methods to language construction. With LSF, Peano attempted to realize part of Leibniz’s dream of a universal language, of which a (...) temporary simplified form of Latin would become the first step. LSF was designed following Leibniz’s fragments compiled by Couturat. By eliminating conventional features from standard Latin, Peano attempted to reduce it to its logical expression. Inspired by the same concerns that motivated the symbolism of Formulario, he aimed for a simple language that owed its fit for international use to its being stripped down to the logical core shared by all languages. To achieve this, Peano proceeded by eliminating inflections from all words and establishing an “algebra of grammar” that governed the rules of word-formation. Simplicity, non-redundancy and computability are key values of LSF inspired from Peano’s mathematical practice. (shrink)

This essay examines the impact of Baconian utilitarianism on Lancelot Thomas Hogben (1895–1975), a biologist whose view of science was heavily intertwined with his support of socialist planning. Like Bacon and Marx, Hogben considered science to be a collective tool of utmost importance for empowering people and improving life conditions through a conscious and methodical intervention on our surroundings. Convinced by the fundamentally applied nature of science, Hogben successfully used the principles of the emerging Marxist historiography of science in his (...) popular science books to teach abstract ideas through their origins in practical life. Furthermore, he extended the view of science as planning from biology and economics to linguistics by designing the international language Interglossa that would also serve to enhance scientific literacy in the lay public.
