学科的本质特性是以一驭万。具有以一驭万特性的学科可以分为两种:以类对象一般规律指导无数个别的典型学科,如数理化等;以个别对象典型意义指导无数他者的学科,如红学、莎学、敦煌学等。延安学属于后一种类型的学科。承认学科的两种分类就应承认延安学是可以成立的。 The essential characteristics of the discipline is a million. There are two kinds of disciplines that have the unique characteristics of one discipline. They guide countless individual typical disciplines in the general laws of class objects, such as mathematical physics and chemistry. They guide the innumerable subjects in typical meanings of individual objects, such as Red Learning, Shakespeare, Dunhuang Learn. Yan’an belongs to the latter type of discipline. Recognition of the two categories of disciplines should recognize that Yan’an can be established.
