Grigory Wyruboff (1843–1913) was a Russian positivist philosopher whose major works remain little-known and largely inaccessible in Russia. As he spent most of his life in France his philosophical, sociological, and methodological writings, written primarily in French, were never translated or published in Russian. This volume, edited by N. D. Lobanov-Rostovsky and E. S. Fedorova, introduces Wyruboff’s Russian-language literary heritage, presenting his memoirs and archival articles with detailed commentary — the first such publication in Russia. Wyruboff’s writings are marked by an original and temperamental style: vivid, engaged, and abundant in historical detail. His memoirs are particularly valuable for their broad depiction of the social life of his era. He offers a thorough account of the education system at the Alexander Lyceum in the late 1850s and at Moscow University in the early 1860s, reflecting on his experiences and proposing potential improvements. As both an observer and participant, Wyruboff provides firsthand descriptions of major historical events, including the Paris Commune of 1871, the Second Carlist War in Spain, and the Russian-Turkish war of 1876–1877. The collection also includes Wyruboff’s articles from French newspapers of the late 1860s, which form a series of sociocultural essays — a journalistic approach novel to Russian periodicals of the time. Through these essays, he systematically analyzes the sociopolitical dynamics of French society and speculates on its developmental trends. Notably, this edition is the first to publish Wyruboff’s sociological analyses based on press materials. The volume is well-organized and encompasses a wide range of Wyruboff’s works, including his early article Russia and Positivism. It also features memoirs by his contemporaries, which offer justified insight into his influence on the moral and scientific outlook of young intellectuals. A distinctive aspect of the publication is its commentary, compiled with the assistance of Wyruboff’s relatives, adding a personal dimension to the scholarly apparatus. This edition represents a significant step in reclaiming Wyruboff’s overlooked legacy, making his Russian-language works available to a broader audience. It will be of interest to scholars of positivism, 19th-century intellectual history, and Russian-French cultural exchange.
