人类构建知识体系,最初是因为人们在对抗大自然过程中感到力不从心。他们一方面开始学着制造物质工具,同时也开始有意或无意积累与自然抗争的经验,总结出一些带有规律性的东西。不同时代的人们,通过对自己身边现象的认识、概括、归纳与整理,总结出在当时社会放之四海而皆准的规律,其中很多一直保留到今天并成为“公理”,即被公认是“本来就存在”的或“先验”的。 Humankind builds a system of knowledge initially because people feel powerless in the fight against nature. On the one hand, they began to learn to make material tools, and at the same time, they began to experience the struggle against nature, intentionally or unintentionally, and summed up some regularities. Through the cognition, generalization, induction and collation of the phenomenon around themselves, people of different ages summed up the law universally accepted by society at that time. Many of them have been retained today and become “axioms”, which are generally recognized as “ Inherently ”or“ a priori. ”
