The main purpose of the introduction in an argumentative essay is to establish the writer's claim or his viewpoint. <em>A claim is a statement that something is true or a fact,</em> although other people might not believe it, and it is used when the <em>writer wants to prove an argument or use as a primary point to support it</em>. Also, many other different reasons are presented to prove that a certain idea should be accepted as logical.
