劳和逸的对立就一,构成了工作波浪式的发展,构成了工作的节奏。只有劳没有逸,就破坏了这种节奏,违反了事物发展的规律.最后必然使工作效率降低,造成工作上的损失,甚至导致事业的失败。劳和逸是工作发展的两个环节,它们是矛盾统一体,休息不等于工作,但休息为了工作,工作劳累了必须休息,借以克服疲劳,积蓄力量,然后继续工作。劳和逸向自己的对立面转化,就推动了工作的发展,这一过程不是简单的重复,而是在原有基础上的提高和发展,不是直线发展,而是螺旋式的上升,因此工作中包涵了休息。在这一意义上,劳和逸是统一的。列宁说不懂得休息的人也不懂得工作,是因为他们把劳和逸孤立起来,把它们看作互不相关的东西,他们认为休息妨碍工作,工作就不能休息,必须日夜突击,才能求得工作的发展。他们不承认事物发展的内部规律,他们以为事物的发展可以依靠外力的推动来完成,可以借助于精神和物质的刺激,依靠某种压力去完成。唯物辩证法认为:事物内部的这种矛盾性 Lao Yi and the opposition on the one, constitutes a wave of development of the work, constitute the rhythm of work. Only if labor does not escape, it will undermine the rhythm and violate the law of the development of things, which inevitably reduces the efficiency of work, causes losses in work, and even causes the failure of undertakings. Lao Yi is the work of the two links, they are the unity of the contradictions, rest does not mean work, but rest in order to work, tired work must rest in order to overcome fatigue, accumulate strength, and then continue to work. Labor and Yat to their own opposites, it promoted the development of the work, this process is not a simple repetition, but on the basis of the original improvement and development, not a straight line, but the spiral rise, so the work includes Rest In this sense, Lao Yi is unified. Lenin said people who do not know how to rest do not know how to work because they isolate Labor and Yat and regard them as unrelated things. They think rest breaks work and work can not rest, and must be raided day and night in order to obtain The development of work. They do not recognize the internal laws governing the development of things. They think that the development of things can be accomplished by the promotion of external forces and can be accomplished by some kind of pressure with the aid of spiritual and material stimuli. Materialist dialectics think: this kind of internal contradictions
