Fallacy, What Is It?

In the Monday's ARW class, we continued to learn about argumentation. And in that class, we focused on fallacies. Do you know what fallacy mean? Fallacy is a mistake when people make an argument. I didn't know that mistakes in an argument are named special names, so at first, I didn't understand what thing I was going to learn. Moreover, I was very sleepy during the class, so I still don't know much about it (Sorry Dan......). So, I have to recheck the material and know what it is.
