Anarchism.

 Aleksey Alekseevich Borovoy (1875-1935) - philosopher, anarchist, and encyclopedist in Russia. He was known, loved, and respected by many great figures of the early 20th century, here are just a few names: P. Struve, I. Ilyin, P. Kropotkin, E. Goldman,... M. Voloshin, A. Bely, V. Mayakovsky, and many, many others. "Many anarchists will find this book heretical" - thus begins the book "Anarchism" (1918), dedicated to P. Kropotkin. Why heretical? The matter is that A. Borovoy became one of the first ideologists of anarcho-individualism in Russia. "Anarchism" is a general characterization and revision of the main provisions of "traditional anarchism" of the 19th-20th centuries, a reflection on his own experience and the legacy of Stirner, Nietzsche, Bakunin, Kropotkin, and many others.
