Matthew Arnold defined the role and qualities of an ideal critic in his essay "The Function of Criticism at the Present Time". According to Arnold, a critic should disseminate the best ideas from literature in a disinterested manner without interference from their own beliefs. A critic must have extensive knowledge of classical and contemporary literature. Their role is to spread noble ideas and establish a flow of fresh thought to benefit society and prepare the ground for future creative works. Arnold's conception of the critic was one of objectivity, broad learning, and an educator of the public.
