Abstract
This article investigates the role of physical and astronomical notions in the formation process of transnational political ideologies. It does so by focusing on the striking example of nineteenth-century early socialist movements, particularly Fourierism. Indeed, Fourier's bold cosmogony enabled him to connect many fields of knowledge, and soon became a powerful vehicle for his ideas on the international scale. The article likewise analyses the ideological process through which Fourierist astronomical conceptions were adopted by foreign socialists, focusing on examples of Polish thinkers such as Jan Czyński and Stanisław Bratkowski who, in drawing on Fourierist ideas and usage of scientific terms, tried to embed his vocabulary in the ongoing nineteenth-century debates about Polish history and, more generally, the burning issue of the independence of the Polish state. Our comparative analysis highlights the contextual influences which contributed to re-shaping such ideas within a new absorbing context.
