在馬克思第二階段經濟學研究中,他第一次具體遭遇近代資產階級工業生產實際和機器化大生產的現實,這促使他徹底放棄抽象的哲學話語,而從哲學意味的實踐活動和社會關系,直接進入到工業文明的物質生產與再生產的構序和塑形活動,人與自然、人與人的關系賦型和動態的生產方式筑模。由此,再以歷史唯物主義和歷史認識論的科學方法,歷史地、現實地全面分析和批判了資產階級社會的歷史發生和現實統治。在《布魯塞爾筆記》和《曼徹斯特筆記》中,馬克思獲得比傳統哲學話語更貼近現實生活的東西,這就是人們現實生產資料的物質生產。物質生產活動是比物質實踐中階級斗爭一類政治活動更基始性的方面。這既可能是《關于費爾巴哈的提綱》中物質實踐概念的基礎,也會是馬克思后來從實踐的哲學概念走向社會歷史深處的基始性的物質生產之思的緣起。

In the second stage of Marx’s economic research,he encountered the reality of industrial production driven by the modern capitalist class and mechanized mass production for the first time,which made him completely abandon the abstract philosophical discourse; left behind the philosophical understanding of practice and social relationships,and directly entered into the forming and shaping activities of the material production and reproduction of industrial civilization; re-figured the relationship of man and nature,and man and man; and modeled the dynamic mode of production. Therefore,with the scientific methods of historical materialism and historical epistemology,Marx comprehensively analyzed and criticized the historical genesis and actual dominance of the capitalist society. In The Brussels Notebooks and The Manchester Notebooks,Marx found something closer to real life than traditional philosophical discourse,namely the material production of people’s real means of production. Material production is more fundamental than political activities such as class struggle. This idea may not only be the basis of the concept of material practice in Theses on Feuerbach,but also the origin of the later Marx’s basic idea of material production from the philosophical concept of practice to the depths of social history.
