Answer:
The purpose of persuasion in writing is to convince, motivate, or move readers toward a certain point of view, or opinion. The act of trying to persuade automatically implies more than one opinion on the subject can be argued.
The idea of an argument often conjures up images of two people yelling and screaming in anger. In writing, however, an argument is very different. An argument is a reasoned opinion supported and explained by evidence. To argue in writing is to advance knowledge and ideas in a positive way. Written arguments often fail when they employ ranting rather than reasoning.
Most people have strong views on controversial topics (ones that inspire extreme points of view or opinions) and are often very willing to share those strong views. However, imagine you are having a discussion with someone who is only willing to share a particular point of view, ignoring yours, which may be in opposition. The ideas presented by that person would be very narrow, almost as if the person has tunnel vision and is merely expressing a personal opinion. If that person does provide you with facts, they may often be skewed or not from a credible source. After the discussion, there is only a slight chance you would be convinced of the other person’s point of view. You may have new ideas you had not considered before or a new perspective, but you would probably not be thoroughly convinced because that person has not made any attempt to present a well-rounded, fact-based point of view. This is why it is essential for you to not only provide your reader with strong, substantiated evidenced, but also to ensure you present an argument that looks at the topic
