He admires the English monarchy and the balance of power between the king, the parliament, and the judiciary. One of the central themes of the book is religious tolerance in England. Voltaire contrasts the more tolerant English society with the religious persecution he witnessed in France. He praises the English for allowing different religious denominations to coexist peacefully and for promoting religious freedom and freedom of conscience. Voltaire's work also explores the intellectual and cultural life in England. He discusses the scientific advancements, such as Isaac Newton's theories, and the progress in education and learning. Voltaire is impressed by the English universities and the level of intellectual discourse and debate in the country. "Letters on England" provides an outsider's perspective on English society and serves as a reflection on the Enlightenment ideals of reason, tolerance, and individual freedom.
