Why is a written argument a good way to defend(support) an opinion?

Writing an argument imply more than one point of view from different sources to communicate a main idea, nor a battle of thinkers who impose their thesis. Arguments differ from debates in the simple fact that all of the participants are winners. The goal is information through investigation. Sometimes is a good exercise to have a one on one correspondence to gather pros and cons of the thesis we are discussing or simply sharing what we think about without getting into a hectic situation.

It is two directions that an argument can follow; implicit or explicit. Based on chapter 1 on Writing Arguments is easy to describe what it is understood from the differences between them.

When we use another source to influence the audience towards an idea through a personal essay, an illustration, etc, for example the Medias used to advertise a new product that offers better results than competitors, this is a sample of implicit argument, and we are creating some emotional bound. Like advertisements based in please an specific desired or need of specific market group.

An explicit argument is when we support our thesis with some evidence, with strong facts, in this case media also used but we are looking for rationality. This case we can use as example journalism, the articles of the news papers, or even a book.

As we notice in both explicit and explicit, an argument needs to have some reasoning with solid proof. At the same time is works in progression where every single stage of it have a valuable meaning until the final result are visible. Thus the process is constantly evolving and sometimes brings us back to the roots of our investigation
