The author elaborates on methodological issues of current tendencies in neoclassical theory and demonstrates the necessity of an alternative model of science, which he calls "realist". According to this perspective, constant and regular conjunctions of economic life events should not be the main object of analysis. Rather, the author proposes to consider structures and mechanisms governing events in question. Instead of deductivism, which, as Lawson believes, is a fundamental feature of orthodox economics, the abductive method of economic explanation is proposed that entails investigation of major powers, on which any social phenomenon depends. Society is thereby regarded not as a closed, but rather as an open system.
