This book is devoted to the history of the Stoic school and its teachings (from the moment it appeared at the turn of the 4th - 3rd centuries BC until its disappearance at the end of the 2nd century AD), as well as the history of Stoicism. The school doctrine as it existed during this period, the author calls the teachings of Stoya in the proper sense. Stoicism is a broader concept. By it, the author understands the peculiar style of reflection that has developed over the course of one and a half thousand years over the content of stoic dogmas and, mainly, the style of practical moral instructions. The real study of Stoya is just beginning. The author defines the task of his book as follows: "I saw the main goal in offering a fairly complete history of the school, in the sense that it should not ignore any noticeable representative of Stoya, not a single term or an essential moment of this teaching."
