How do I write a descriptive essay?The essay should be from three points of view and one should be from an objective view.
This is a very interesting question. The most important point that you need to address is you need to define what is "objective." Also you need to define how a person gets to know something objectively. In my opinion, there is no such thing as objective knowledge. All knowledge is condition by the one who possess that knowledge. This is to say that all knowledge is colored and influenced by the person's experiences, point of view, culture, and history. This is one of the reasons why all people have their own take on an issue or event.
In light of this, I can understand the first part of your paper. You are giving three different points of view. The second part, like I said, above will be tricky.
With that theoretical point stated, if you were going to write a descriptive essay on three different points and then an objective point, then it would be interesting to lay out the three points and then compare them to what you call objective. This approach has the benefit of being straightforward. Finally, you can draw some conclusions as to why there are so many different points of view.
