ENThe aim of this paper is to show the academic links inherent in the idea of ethnographical-statistical studies of Lithuania conceived by the Latvian ethnographer Eduards Volters (1856–1941). In as early as the end of the nineteenth century, the Latvian linguist and ethnographer was working at the Imperial Russian Geographical Society and was developing ethnographical-statistical studies to determine the “tribal” composition of the population. In an original way the theory integrated the concepts of the history of ideas and ethnographical statistics. In 1930 Volters engaged in the activities of the Lithuanian Scientific Society and introduced the concept of “the soul of a nation” in his ethnographical-statistical studies. The author of this article tests the hypothesis that the beginnings of “the soul of a nation” concept in relation to the Lithuanians are connected with the historical anthropological perspective. The author theoretically analyses the rhetoric of Volters’ idea of ethnographical statistics from the following points of view: (1) ethnographical-statistical studies of Lithuania, (2) a romantic nation, and (3) the idea of science and education. Keywords: Eduards Volters, ethnographic-statistical studies of Lithuania, Johann Gottfried Herder, romantic nation, soul of a nation. [From the publication]
