力是什么?《墨经·经上》说“:刑之所以奋也”。“刑”即形体。“奋”原指鸟张开翅膀从田野起飞。从春秋时期起,“奋”字大多用于描述物质的、精神的或运动的状态改变,所谓“奋飞”、“振奋”、“奋发”等都是这个意思。如果保守某种状态就谈不上“奋”。《墨经》还以举重为例,说明重物的状态在被举的刹那间发生了改变,人体因之需要付出力。可见,《墨经》的定义是颇有科学见地的。中世纪欧洲的哲学家和工艺学者都错误地以为力是维持运动的原因。伽利 What is the power? “The scriptures by the” said “: the reason why the penalty Fen”. “Criminal ” is the body. “Fen ” originally refers to the bird open wings take off from the field. Since the Spring and Autumn Period, most of the words “Fen” are used to describe the change of state of material, mental or sports. The so-called “Fenfei”, “Excitement”, “Fengying”, etc. all mean this. If you keep some kind of state, you will not be able to talk about it. “Mojing” also take weight lifting as an example, indicating the state of heavy objects in the lifting of the moment has changed, the human body need to pay for it. Can be seen that the definition of “Mohist” is quite scientific insight. Middle Eastern European philosophers and craftsmen mistakenly thought that power was the reason for maintaining the movement.
