Confucianism was founded by the ancient Chinese philosopher and educator Confucius around 500BC. The core teaching is about cultivation of virtue and moral of the individual.
After the influence of Taoism and Buddhism around Song Dynasty, a new branch of Confucianism was found: Neo-Confucianism. The key element of Neo-Confucianism is that they beleive universe could be understood through human reason, a harmonious relationship between the universe and the individual can be cultivated.
Around early 20th century and after post-Mao era, another new school of Confucianism was found: New Confucianism. It is a political, ethical, and social philosophy using metaphysical ideas adopted from both Western Philosophy and ancient Confucianism.
Lately, there is a scholar who proposed "Post-New-Confucianism" which based on the foundation of adopting concepts from both New-Confucianism and Marxism.
I guess very soon, a "Confucianism 4.0" might be surfaced by some other scholars.
It is not a bad idea to adopt Confucianism and tailor it to suit contemporary suitation. However, the evolved Confucianism teachings seem to be getting further and further away from the original teachings by Confucius.
To what extent should we keep to the ancient teachings? Should we continue to evolve Confucianism by adopting contemporary teachings?
