This book has not been republished in our country since the 20s: it was believed that it was written under the influence of the reactionary ideas of F. Nietzsche. At the same time, Spengler spoke about the inevitable dehumanization of European culture, about growing technicalism as a new source of power. He can rightfully be called a successor to the traditions of N.Ya. Danilevsky and K.N. Leontyev, who acutely posed and deeply comprehended pan-European and global problems.
