For over 2000 years, we've only known about 3 of the "100 Schools of Thought," but the recovery of nearly 2400 bamboo slips is changing that. Though the vast majority of these slips remain to decipher, a diversity of thought is emerging. Western skepticism over the antiquity of key texts in China's received canon has also lost a foothold. There's even an exchange between Confucius and one of his disciples, wherein Confucius, counter to all we've known of him, embraces the roles of magic and spiritualism. The importance of the find won't be understood for decades, but the Tsinghua slips join two previous recoveries of China's past from Qin Shi Huang's purges. This was the most recent article I've found. Here's an extract:
The newly discovered texts challenge long-held certainties about this era. Chinese political thought as exemplified by Confucius allowed for meritocracy among officials, eventually leading to the famous examination system on which China’s imperial bureaucracy was founded. But the texts show that some philosophers believed that rulers should also be chosen on merit, not birth—radically different from the hereditary dynasties that came to dominate Chinese history. The texts also show a world in which magic and divination, even in the supposedly secular world of Confucius, played a much larger part than has been realized. And instead of an age in which sages neatly espoused discrete schools of philosophy, we now see a more fluid, dynamic world of vigorously competing views—the sort of robust exchange of ideas rarely prominent in subsequent eras.
