A science-based conversation about the current state of rural areas, prospects for rural human capital and trends in rural differentiation is impossible without the conceptual approaches and futuristic projects of great Russian agrarian scien-tists. The article presents an attempt of comparing such ideas of two outstanding social thinkers of the early 20th century — Alexander Bogdanov and Alexander Chayanov, fo-cusing on their utopias as representing the essential features (proletarian and peas-ant) of their social-economic and cultural-ethical views. Bogdanov and Chayanov had extensive encyclopedic knowledge and brilliant organizational skills; they wrote original works on social philosophy and political economy; both were prominent leaders of al-ternative social-political directions of the Russian Revolution. Moreover, Bogdanov and Chayanov wrote several famous utopias: Bogdanov’s utopia develops Marxist ideas of proletarian revolution and construction of socialism not only on earth but also in space; Chayanov’s utopia of moderate cooperative socialism defends the new revolutionary significance of the peasantry. The proletarian ideologist Bogdanov was skeptical about the political potential of the peasantry, arguing that opponents of proletarian revolution would use peasant conservatism against socialist revolution. The peasant ideologist Chayanov was skeptical about the creative potential of the working class, predicting that in the coming social revolution it would be used to build authoritarian-bureau-cratic socialism. However, both thinkers sought prospects for rural-urban development through the analysis of possible ways of interaction between man and nature. Despite the ignorance of the positive revolutionary potential of the proletariat (Chayanov) and the peasantry (Bogdanov), both thinkers made huge contributions to the theory and practice of the Russian Revolution, and their utopian ideas still inspire the search for a new just, humane and happy world. © 2023, Russian Presidential Academy of National Economy and Public Administration.
