Take Li Zhengdao's "lifestyle" as an example. Everyone has their own way of life, each with its own strengths and characteristics, which cannot be unified. However, these different lifestyles do have their own advantages and disadvantages. Being drunk is a way of life, selfless work, selfless dedication, and also a way of life.
Inaction, muddleheaded, is a way of life, self-improvement, forge ahead, but also a way of life; Being old before you get old is a way of life, and getting stronger when you get old is also a way of life, keeping pace with the times. There is no doubt that Li Zhengdao's "lifestyle" is positive, noble, admirable and worthy of emulation.
The role of comparative argument:
Everything in the world often exists in comparison. "Only contrast can distinguish". Once two things are compared, we can tell the difference between them.
Therefore, in argumentative writing, the method of comparative argument is often used to compare two contradictory or opposing things and reasons from both positive and negative aspects, so as to reveal the essence of things and make the things expounded more profound and convincing. Contrast between true and false, you can go from false to true; The contrast between good and evil can suppress evil and promote good; Contrast between right and wrong can set things right.
Therefore, the use of positive and negative contrast argument is more powerful and clearer than just reasoning from the front. Especially for topics with comparative factors, for example, it is suitable to write in this way.
