Matthew Arnold was a 19th century British poet and cultural critic. In his work Culture and Anarchy, he defines culture as the study of perfection - a harmonious perfection that develops all sides of humanity. Arnold believes culture brings about a perfection in which both beauty and intelligence are present, uniting "the two noblest things" - sweetness and light. He connects these ideas of sweetness and light to the Greek words "aphros" and "euphuia". For Arnold, culture is not about having or resting, but about growing and becoming perfect.
