“There are different kinds of logical fallacies that people make in presenting their positions. Below is a list of some of the major fallacies. It is a good idea to be familiar with them, so you can point them out in a discussion, thereby focusing the issues where they belong while exposing error.
“It is true that during a debate on an issue if you simply point out to your “opponent” a logical fallacy that he/she has just made, it generally gives you the upper hand. But then, merely having the upper hand is not the goal: truth is. Nevertheless, logical fallacies hide the truth, so pointing them out is very useful.”
