Two concepts of equilibrium, the equation of unified knowledge and two concepts of stability

The economic science is again in a crisis and a new solution prolegomena to any future study in economics, finance and other social sciences has just been published by the International Institute of Social Economics in care of the MCB University Press in England. The roots of the major financial and economic problems of our time lie in an open conflict between theory and practice. In the 1930s and before the conflict was between classical theory and given realities. In the 1990s the conflict appears between the now prevailing modern, Keynesian theory and the actual realities. In addition during the twentieth century a great argument developed between the two schools of thought, argument which is not yet settled. In one sentence, the prolegomena tried and was successful to solve the conflict between theory and practice and the big doctrinal dispute of the twentieth century. It was a struggle of research and observation over half a century between 1947 and 1997.
