As part of the "Selected Works" of the head of the "critical direction" in Russian Marxism P.B. Struve (1870-1944), for the first time in such a full volume and on a strictly scientific basis, works are published that cover almost his entire career (from 1901 to 1938) and show the development of the central ideas of the thinker: the need for religious justification of the social ideal, intelligentsia and revolution, "Great Russia," "spiritually-based patriotism." In addition, three unincarnated ideas of the philosopher were reconstructed - the books "Culture and Freedom" (1905), "State, Intelligentsia, Revolution" (1908) and "Fundamentals of Political Economy" (1923). The publication is equipped with a preface and scientific commentary.
