From: The Book of Rites, c. 4^th – 2^nd century BCE, translated based on James Legge's version

Yù bù zhuó, bù chéng qì; rén bù xué, bù zhī dào. Shìgù gǔ zhī wáng zhě jiàn guó jūn mín, jiào xué wèi xiān. [Pinyin]

The jade uncut will not form a vessel for use; and if men do not learn, they do not know the way (in which they should go). On this account the ancient kings, when establishing states and governing the people, made instruction and schools a primary object.
