学有师承,是进行教学的一个基本条件。古語说:“学无师承,終难求益也。”人类从劳动中积累经验,又从劳动中傳授經验。就传授经驗来说,是“为人所师承”,就接受經驗来说,是“师承于人”。教师对学生傳授书本知識也同是如此,既“为人所师承”,也仍需“师承于人”。 Learning from teachers is a basic condition for teaching. As the old saying goes: “Learning without a teacher means that it will be hard to seek benefits.” Humanity gains experience from work and teaches experience from work. In terms of imparting experience, it is “for the sake of the people”. In terms of accepting experience, it is “a division of the people”. The same is true for teachers in imparting knowledge of books to students. It is not only “for the sake of the people” but also “for the sake of teachers.”
