唯物辩证法的基本范畴之一,形式与内容这对范畴告诉我们,任何事物都有它的内容,也有它的形式,任何事物都是形式和内容的统一体。在形式与内容的辩证关系中,内容是决定的,起主导作用的因素,而形式是从属于内容的。一定的内容要求一定的与之相适应的形式,而形式又不是消极的因素,在一定的条件下它又反作用于内容,这个基本原理是我们讨论标记符号和类目体系关系的理论基础。用这个观点正确地认识标记符号和类目体系的关 One of the basic categories of materialist dialectics, form and content This category tells us that everything has its content, its form, and everything is a unity of form and content. In the dialectical relationship between form and content, content is the decisive and dominant factor, and the form is subordinate to the content. A certain content requires a certain form of adaptation, and the form is not a negative factor. Under certain conditions, it reacts to the content. This basic principle is the theoretical basis for our discussion of the relationship between the symbol and the category system. Use this view to correctly understand the relationship between the markup and the category system
