Which central theme from Samuel Johnson’s other writings or 18th-century literature is most prominently reflected in his work Rasselas?
Explanation
Samuel Johnson’s Rasselas primarily explores the theme that genuine happiness is ultimately unattainable, a concept he also develops in his poem "The Vanity of Human Wishes." This contrasts with themes like linguistic precision, universal knowledge, or self-reliance found in other 18th-century works.
