Confucius: Look into your own heart
If you look into your own heart, and you find nothing wrong there, what is there to worry about? What is there to fear?
Confucius (Qufu, 28 september 551, Qufu, 479 BC) was a Chinese teacher, editor, politician, and philosopher of the Spring and Autumn period of Chinese history. The philosophy of Confucius emphasized personal and governmental morality, correctness of social relationships, justice and sincerity. His followers competed successfully with many other schools during the Hundred Schools of Thought era only to be suppressed in favor of the Legalists during the Qin Dynasty. Following the victory of Han over Chu after the collapse of Qin, Confucius's thoughts received official sanction and were further developed into a system known as Confucianism.
