The classic work Homo ludens [Man the Player] is devoted to the all-encompassing essence of the phenomenon of play and its universal significance for human civilization. The articles The Task of the History of Culture, On the Historical Ideals of Human Life, and the Political and Military Significance of Chivalric Ideas in the Late Middle Ages thoroughly consider philosophic and methodological issues that remain relevant to this day in the field of history and cultural studies. They reveal the theoretical and moral foundations of I. Huizinga’s approach to history and culture. The published works, with their analysis of fundamental problems of the theory and history of culture, are marked by high scholarly value, clarity and persuasiveness of exposition, vividness and diversity of factual material, and broad coverage—along with undeniable artistic merits.
