53.什么是思维?思维是人脑对客观事物的间接的概括的反映。它反映事物的本质和内部规律性,是借助于词来实现的。例如,对于“什么是球”这个问题,我们动脑筋思考,抛开那些非球所必备的如颜色、大小、表面质地等属性,指出:“球是指由中心到表面各点距离都相等的立体。”这样就把球跟某个具体的皮球、乒乓球、足球和篮球区别开来,找到了球的本质。这种认识事物的本质属性和内部规律的过程就是思维。
53. What is thinking? Thinking is the brain's indirect reflection of objective things. It reflects the essence of things and internal regularities, is by means of words to achieve. For example, we think about the issue of “what is a ball” and put aside the necessary attributes such as color, size and surface texture of the non-sphere and point out that “the sphere is the distance from the center to each point of the surface . ”This distinguishes the ball from a specific ball, table tennis, football, and basketball and finds the essence of the ball. This process of understanding the essential attributes and internal laws of things is thinking.
