与从事美德伦理学研究的熟知印象不同，麦金太尔早期是一名激进的马克思主义者，其早期思想阶段经历了一个复杂的发展过程。本文分为五个部分，展现了麦金太尔从早期接触马克思主义萌生社会主义人道主义思想到以人道主义解释马克思主义遇到困难最终离开马克思主义的过程。

文章的第一部分从思想因素、政治因素和文化氛围三个方面来介绍麦金太尔社会主义人道主义思想诞生的背景；文章的第二部分将具体介绍麦金太尔是如何寻找到马克思主义和基督教之间的契合点的，由此奠定了麦金太尔早期思想的基调；文章的第三部分将结合麦金太尔在新左派运动中的创作灵感，从两方面展开论述麦金太尔的社会主义人道主义思想，一是批判机械化的斯大林主义和缺乏确定道德基础的自由主义，二是探讨麦金太尔如何找到弥合道德、欲望与历史的途径；文章的第四部分，将遵循麦金太尔的思想发展顺序，探讨人性的观点在革命理论的发挥，并进一步论述麦金太尔关于革命的组织问题、工人阶级的革命潜力问题以及社会主义与民主自由之间的辩证关系问题的看法；文章的第五部分，重点介绍了麦金太尔早期思想的转变。通过分析麦金太尔对马克思革命思想的反思以及在人性理论的新观点，我们得出观点即麦金太尔认为马克思的革命实践观存在道德缺场，未能充分发掘实践内在善和目的的意义，促使其远离马克思主义。

毫无疑问，麦金太尔的思想受益于马克思，他远离马克思主义在某种意义上是要沿着马克思实践的道路继续前进。

Contrary to the familiar impression of engaging in the study of virtue ethics, McIntyre was a radical Marxist in his early years, and his early ideological stage underwent a complicated process of development. This paper is divided into five parts, showing the process from McIntyre's early contact with Marxism to the emergence of socialist humanitarian thought, to explain Marxism with humanitarian difficulties and finally left Marxism.

The first part of the article introduces the background of the birth of McIntyre's socialist humanitarianism thought from three aspects: ideological factors, political factors and cultural atmosphere. The second part of the article will specifically introduce how McIntyre found the meeting point between Marxism and Christianity, which laid the keynote of his early thought; The third part of the article will combine McIntyre in the new left movement of creative inspiration, from two aspects McIntyre socialist humanitarian thought, one is the moral foundation to determine critical mechanization stalinism and lack of liberalism, the second is to explore how McIntyre to find ways of moral, desire and history; The fourth part of the article will follow the development order of MacIntyre's thought, explore the development of human nature in revolutionary theory, and further discuss MacIntyre's views on the organization of revolution, the revolutionary potential of the working class, and the dialectical relationship between socialism and democracy and freedom. The fifth part of the article focuses on the transformation of MacIntyre's early thought. By analyzing MacIntyre's reflection on Marx's revolutionary thought and his new point of view on the theory of human nature, we conclude that MacIntyre thinks that there is a moral deficiency in Marx's revolutionary practice view, and that he fails to fully explore the intrinsic goodness and purpose of practice, so as to push it away from Marxism.

There is no doubt that MacIntyre's thought benefited from Marx, and his departure from Marxism in a sense is to continue along the path of Marx's practice.
