人比其他动物高明,在于人有抽象思维的能力。有人做过一个试验,点燃一排蜡烛,然后从水缸中舀水将其浇灭。猩猩反复看了几次以后,居然也能模仿。但是,如果河边着起火来,猩猩绝不可能从河里舀水把火浇灭,只能眼巴巴地看着大火把一切烧个精光。这是因为猩猩没有“水”的概念,它不懂得河里的水与缸里的水是一样的水。 People smarter than other animals, is that people have the ability to abstract thinking. Someone had done an experiment, lighting a row of candles, and then bailing it out of the tank. Orangutan repeatedly read several times, actually can imitate. However, if the river was hit by a fire, orangutans would never be able to wade water from the river to extinguish the fire, only to see the fire burning everything to burnish. This is because the orangutan does not have the concept of “water” and does not know that the water in the river is the same as the water in the tank.
