The opportunity for young Engels to investigate national economics and its inspirations
National economy is one of the important parts of Marxist theory,and one of the necessary conditions for Marx and Engels to construct historical materialism.The previous studies have not fully explained the opportunity and significance of Engels'first study of national economics.Based on reviewing the previous theoretical achievements,and taking The Outline of the Criticism of National Economics as the research focus,this article,by analyzing the young Engels'study,business and political activities,clarifies that Engels has drawn inspirations of integrating German philosophy,French socialist thoughts and national economics from the works by socialist Ricardo.Only by experiencing the opportunity to solve the British social problems,did Engels have to temporarily give up the unique German way of thinking,turn to the national economy instead,realize the importance of the transformation of philosophical methodology and research paradigm,and then discover the fundamental force to promote the historical process.
