如何理解费尔巴哈伦理学的性质是伦理学研究和教学中的一个难点问题。本文着重阐明了费尔巴哈伦理学在自然观上的“唯物主义”与在社会历史观上典型唯心主义的关系以及费尔巴哈伦理学在一系列根本问题上的唯心主义表现 ,说明在伦理学中由自然观上的唯物主义向唯物史观的跨跃是一个艰苦的质变和飞跃过程。由于主客观方面的种种原因 ,费尔巴哈没有实现这一飞跃。 How to understand the nature of Feuerbach’s ethics is a difficult issue in ethics research and teaching. This article emphasizes the relationship between the “materialism” of Feuerbach’s ethics in the view of nature and the typical idealism in the view of social history, as well as the idealistic performance of Feuerbach’s ethics on a series of fundamental issues. In the ethics, the leap from the materialism of the concept of nature to the historical materialism is a difficult process of qualitative change and leap. Due to various reasons in the subjective and objective aspects, Feuerbach did not achieve this leap forward.
