This study aims to evaluate the ideas on the scope and method of economics of Joseph Schumpeter who is one of the important economists of the 20th century. The study consists of four sections: In the first section we underline the interesting points of his life to understand the roots, background, or 'vision' of his thought system. In the second section, we will examine his methodological views that he asserted in his first (but translated into English only in 2010) book. Third section will be concerned with his 'analysis of economics' which refers to his critics of Leon Walras's general equilibrium analysis (as static) and his own alternative (dynamics analysis of capitalist economies) about the central subject matter of economics. In the fourth section we will treat his approach about the development/evolution process of economic thought in time. The study concludes with a brief assessment: Schumpeter is one of the rare economists who can build his own thought system in the history of economics, and he embraced a pluralist perspective in the field of the methodology of economics.
