人类认识世界的历史,就是由特殊到一般,再由一般到特殊,从而从相对走向绝对的历史。在历史发展的不同时期,因生产的需要而产生并伴随着生产的发展和自身的矛盾运动而发展的各门学科,都是人类对世界的认识从相对走向绝对这一矛盾双方转化过程的各个阶段的不同表现。几何学的发展,因平行公理的不同而先后产生的三种几何体系就是其中的一例。 The history of mankind’s cognition of the world is from the special to the general, from the general to the special, and thus from relative to absolute history. In different periods of historical development, the various disciplines developed due to the needs of production and accompanied by the development of production and their own contradictions and movements are all aspects of the human understanding of the world from the relative to absolute transformation of both contradictions Different stages of the performance. The development of geometry, three kinds of geometrical systems produced successively due to the parallel axioms are one of them.
