This book presents the methodological and theoretical foundations for economic personalism through a detailed investigation of human action from two different, yet complimentary perspectives: from the personalist perspective of Karol Wojtyla in the "Acting Person" (1961), and the free-market perspective of Ludwig von Mises in "Human Action" (1963). Both Wojtyla and Mises approach their subjects with a well-developed praxeology (i.e., a theory of human action). By comparing and contrasting the viewpoints of Wojtyla and Mises, the authors develop a comprehensive praxeology capable of analyzing human action from moral and economic perspectives. "Beyond Self-Interest" illustrates how a unified praxeology could encourage more sustained analysis of the moral dimensions of economic activity while simultaneously softening the utilitarian prejudice of contemporary economic analysis.
