The novels of Charles Dickens cover a wide range, social, moral, emotional and psychological. Thus, he is much concerned with very ordinary people but also with abnormality (e.g. eccentricity, depravity, madness, hallucinations, dream states). He is both the most imaginative and fantastic and the most topical and documentary of great novelists.
Biographers have only since
mid-20th century known enough to explorethe complexity of Dickens'
nature. Critics have always been challenged by his art, though from the
start it contained enough easily acceptable ingredients, evident skill
and gusto to ensure popularity.
