早期馬克思的思想，尤其是對人的存在與問題，受到黑格爾與費爾巴哈很大的影響。但是馬克思並不侷限於兩位先哲的理論框架，而是將自己的理論深深紮根在人這個實際的個體上，馬克思真正關注的是人在現實社會中的處境，並致力於將理論化為實際行動。 身處在資本主義社會與現代性的洪流裡，「異化」的感受深深地衝擊我們，馬克思從異化的角度，試圖去建構一個沒有異化的自由人聯合體。自由人聯合體是馬克思運用啟蒙以來的主體理性與分析資本主義的歷史走向，所建構出來的理想社會。針對資本主義中異化人的處境，馬克思企圖將資本主義社會中的原子式個人轉為聯合起來的自由人，並且打造一個聯合勞動、彼此互助的自由人聯合體。雖然許多人對他的理論有褒有貶，但是卻不能否認，馬克思理論的啟發性與影響力。 關鍵字：馬克思、費爾巴哈、黑格爾、異化、類存在、自由人聯合體 / In the early thoughts of Marx, especially for human existence and problems, are effected by Hegel and Feuerbach very much. However, Marx didn’t limit himself to the theory frame of these two philosophers but rooted his theory in human being individual deeply.
