The point of view in Walker's essay is first person narrative.  In this mode of narration, the use of "I" and "We" is dominant as the narrator is also a character of the work.  Walker's writing fits this characterization because she is the primary character in the essay, as it is a reflection of her life and her association with the concept of beauty.  It is through the first person that we, as the reader, fully understand what is happening in the minds of both the main character and the other characters.   As the reader, we understand what is happening through the narrator and through the first person.  It makes sense that Walker would use first person narration because the story is about her experiences with the concept of being beautiful.  In showing that beauty can exist on both physical and emotional levels, there has to be a delving of the concept.  This is best done through Walker's first person narration as it allows us to examine the concept as she examined it.
