What is the central theme of Sir Thomas More's "Utopia"?

The central theme of Sir Thomas More's "Utopia" is indeed the pursuit of an ideal society. In the book, More presents a fictional island where social, political, and economic systems are designed to promote equality, happiness, and a harmonious way of life, contrasting sharply with the societal issues of his time. The description of Utopia serves as a critique of contemporary European societies, and More uses this setting to explore philosophical questions about the ideal human community. By presenting a society where resources are shared, education is valued, and property is held in common, More invites readers to consider what an ideal society might look like and challenges them to reflect on the flaws of their own social structures. This theme resonates throughout the text, making the pursuit of an ideal society the cornerstone of More's arguments and ideas, which is why this option is the correct answer.
