The book of Leonid Luks is devoted to the disputes of thinkers of the Russian Diaspora about the causes and consequences of the Russian revolution, as well as about the causes of the European crisis of the first half of the 20th century. The author's focus is on three groups of emigrants who played a significant role in these discussions: firstly, the authors of the Milestones collection published in 1909, and secondly, the publishers of the Novy Grad magazine created in 1931, which continues in many respects the ideas of Vekh. In addition, the articles of the collection are devoted to the ideological opponents of "Vekhovtsy" and "Novogradtsy" - the movement of Eurasians that arose in 1921, which many authors considered the most interesting ideological trend of Russian emigration.
