The article analyzes the meaning and role of justice as the foundation of social systems of security. It aims to present justice as a formal and axiological principle shaping interpersonal relations, the intersubjectivity of law and morality, and the state of social equilibrium (isoropia). The central hypothesis asserts that justice functions as a regulatory criterion for evaluating actions and decisions influencing collective security. Drawing on classical and modern legal thought (Aristotle, Cicero, Ingarden, Kant), the author explores links between the distribution of goods, individual claims, and the preservation of social order. Key research problems include whether justice relies on independent arbitration, how guilt and intent affect its assessment, how law and morality jointly shape security norms, and whether communities can endure without equilibrium between these control systems. The article contends that justice, rooted in conscience and selflessness, is essential to communal cohesion and underpins the legitimacy of legal systems that safeguard social values.
