EU social policy - its development and perspectives
From the point of víew of historical development, human society functioned and functions as a structurally and functionally complex rational auto-regulating or regulated open system that is composed of people and institutions. The surroundings of the social system are always formed by the system of nature, which provides the material sources for it. In such form and symbiosis with nature the human society exists and develops, from the auto-regulating systems to the systems regulated by the state.
