The author has particular interest in studying the last views of the anarchist Peter Kropotkin. They are considered controversial, weak studied and never had been put together in any system. Despite an incomprehension, and sometimes open rejection to violations of established in the historic community of traditional approaches to the radical views in the classical anarchism of P. Kropotkin, the author tried to find a system-making idea in the last anarchical views of Kropotkin and logically to link them into one united theory. In any case this task was extremely interesting. This book presents the most significant provisions of the philosophical and political views of prominent Russian and English anarchist Peter Alexeyevich Kropotkin. The author divided them into philosophical, anarcho-reformist and federalistic. He aspired to explain the last views of Kropotkin in the frame of the theory of the anarcho-reformism of the great anarchist and to outline his transition from the classical anarchical position into the non-classical one.
