Argument, also called judgment, is the author's point of view. Logically, argument is a judgment whose truth needs to be confirmed. It is the author's views, opinions and attitudes on the issues discussed. It is the center of the whole argumentation process, shouldering the task of answering "what to demonstrate" and clearly indicating what the author is in favor of and against. It is a statement with clear meaning.

In a long article, arguments are divided into central arguments and sub-arguments.

The central argument is the author's most basic view of the problem under discussion. It is the most important ideological viewpoint put forward by the author in the article, and it is a high generalization and concentration of all arguments. The full text should focus on this point.

Sub-arguments are some ideological viewpoints subordinate to and used to elaborate the central argument. Every argument also needs to be demonstrated. The relationship between the central argument and the sub-argument is the relationship between proof and proof. Any argument that is proved to be effective becomes a powerful argument at the center of the argument.
