Confucianism is humanistic and focused on human concerns. That humans are innately good.
We progress and regress and always have. There have been enlightened ages, and these ages often prove later to be mixed blessings if not outright misguided. The legalist schools of Confucianism did practice book burnings. They felt that many Taoist texts and more “arcane” knowledge encourages public disharmony.
“The superior man cannot be known in little matters, but he may be entrusted with great concerns. The small man may not be entrusted with great concerns, but he may be known in little matters.”
“When a man’s knowledge is sufficient to attain, and his virtue is not sufficient to enable him to hold, whatever he may have gained, he will lose again.”
Confucius, The Confucian Analects
