Who is the main expositor of Confucian philosophy?

The main expositor of Confucian philosophy is indeed Confucius. He lived during the 5th century BCE in ancient China and is considered the founder of Confucianism, a system of thought that emphasizes morality, social relationships, and justice. Confucius’ teachings and ideas, which were compiled by his followers in works such as the Analects, focus on the cultivation of virtue and the importance of filial piety, respect for elders, and proper conduct in various social roles. His influence on Chinese culture, government, and education has been profound and lasting, shaping the moral framework of East Asian societies for centuries.

The other figures listed have significant philosophical contributions but do not relate directly to Confucian philosophy. Laotzu is associated with Daoism, which emphasizes harmony with the Dao, or "the Way." Buddha, the founder of Buddhism, focused on the nature of suffering and the path to enlightenment. Socrates, a classical Greek philosopher, is known for his contributions to Western philosophy, mainly concerning ethics and epistemology, but he does not align with the teachings or philosophy that defines Confucianism.
