马克思在《提纲》的第二条中指出：“人的思维是否具有客观的真理性，这不是一个理论的问题，而是一个实践的问题。人应该在实践中证明自己思维的真理性。”马克思的这断话表明了人们在只有实践中才可以检验自己认识的真理性。说到这里很有必要谈谈什么是真理，真理是人们对客观存在物及其历史发展的规律的正确反映。所谓检验真理，就是指检验人的主观认识与客观事物的本性及其历史发展的规律相符合。众所周知，实践是人们通过工具和手段来认识事物和改造客观事物，满足自身需求的活动，具有直接现实性的特点。判断我们的认识是否真理，必须通过实践的检验才能得到最终的结果，在检验真理的过程中必须把人的主观能动性和事物的客观实在性相结合起来，这样才能明白或判断是否真理。人的主观意识通常就是以自我为中心，它不能作为检验真理的标准，离开了实践去探索人的思维是否正确是一个毫无意义的事情，而真正能够检验真理的是“实践”，因此，只有通过实践的检验才能证明思维的真理性，才能成功地获得真理。

In the second article of the outline, Marx pointed out: "whether people's thinking has objective truth is not a theoretical problem, but a practical problem. People should prove the truth of their thinking in practice." Marx's conclusion shows that people can test the truth of their understanding only in practice. At this point, it is necessary to talk about what is truth. Truth is the correct reflection of people's objective existence and the law of its historical development. The so-called test of truth refers to the test that people's subjective understanding is consistent with the nature of objective things and the law of historical development. As we all know, practice is an activity that people understand things and transform objective things through tools and means to meet their own needs. It has the characteristics of direct reality. To judge whether our cognition is true or not, we must pass the test of practice to get the final result. In the process of testing the truth, we must combine people's subjective initiative with the objective reality of things, so as to understand or judge whether it is true or not. People's subjective consciousness is usually self-centered. It can not be used as the standard to test the truth. It is meaningless to explore whether people's thinking is correct without practice, and what can really test the truth is "practice". Therefore, only through the test of practice can we prove the truth of thinking and successfully obtain the truth.
