English: A book by Phạm Quang Sán (1874–1932) introducing new forms of learning based on French philosophy while discussing Confucian texts used in the Imperial Examination system.

At the beginning of the book Phạm Quang Sán writes that the purpose of this book is as follows:

『今當學界一新之日，而民間講習，猶多株守舊套。蓋以我國千餘年來，漢文傳習久已，印於國民之腦中，而國語新學汗漫難通，進化之阻力，實根於此。』

(“At present in this new age of scholarship, teaching among the people still follows the stale old ways. This is because in our kingdom for more than a thousand years now Chinese characters have been passed down and are imprinted in people’s brains, so it is difficult for the spread of quốc ngữ new scholarship to break through. The force obstructing progress has its roots in this.” - Translated by Lê Minh Khải.)

Indicating that it's a revolutionary new work reforming the ways that the Vietnamese elites learn.
