In this ambitious book the authors challenge mainstream economic theory by removing the principle of individualism from its foundation. They refer to that version which fails to recognize the existence of the interests of society as such, and does thus exclude the role of the state as an independent market player seeking to realize these interests. The outcome is a new theoretical concept called "Economic Sociodynamics". The book justifies in detail the key theses of the said concept as well as its initial postulates and basic notions, such as the sociodynamic multiplier and the rational behavior of the state.
