Mark Aldanov - Russian prose writer, publicist, author of essays on historical topics, philosopher and chemist. Aldanov sought to show the key role of chance in events that change the face of the world and affect the fate of entire generations. The event, according to Aldanov, arises as if spontaneously, contrary to the logic of things and regardless of the subjective motives of its participants, however, even repeating itself, it does not become an instructive experience: from century to century, humanity makes the same mistakes.
