More than once I’ve found Andrew Hong’s Chinese Culture category to be a good source for easy introductions to basic, relevant Confucianism. Here’s the latest:
Confucianism has a strong focus on the leader as the chief means for bringing about peace and harmony. And one important dynamic that shapes the Confucian leaders’ understanding of their place in all things is the concept of the Mandate of Heaven (tianming, 天命). And this concept continues to influence how Chinese leaders understand their role today. . .
I assume Confucianists would find plenty to pick at in these brief introductions – heck, I don’t even agree with some of his theology and exegesis – but if you know next to nothing about Confucianism, this is a handy place to start.
