“全部社会生活在本质上是实践的”这一光辉论断是马克思于一八四五年春在《关于费尔巴哈的提纲》中提出来的。这是马克思运用唯物主义观察社会历史得出的重要结论。本文着重从实践入手,得出实践是社会得以形成的基础、实践构成了社会生活的基本领域、实践推动社会的发展、实践也决定着人类的意识的发展等论断。同时,探讨我国在发展社会主义强国过程中也应该坚持实践第一的原则,坚持科学发展观。 The glorious assertion that “all social life is practically essential” was put forward by Marx in the “Outline of Feuerbach in the Spring of 1845”. This is an important conclusion drawn by Marx in using materialism to observe social history. This article focuses on practice, and draws the conclusion that practice is the basis for the formation of society, practice constitutes the basic field of social life, practice promotes the development of society, and practice also determines the development of human consciousness. At the same time, explore the principle that our country should adhere to the principle of “first” in the course of developing the socialist strong nation and adhere to the scientific concept of development.
