This is a very good question from Chuks. The primary functions of creative writers are to inform, educate, entertain. Writers are the sharpest sensors that create the idea, while "critics are like brushes of noblemen's clothes," said Matthew Arnold. They refine work of art.
Even as Coleridge opined that "critics are creative artists who have failed," I am of the opinion that objective critics are teachers of creators of literary work.
So, I can arguably say that critics and writers are equal and important in literary field.
