物竞天择是自然现象,优胜劣汰是竟与择的结果。现象与结果的必然联系,被称之为自然法则。然而,社会现象不同于自然现象,经过人类选择的优与劣,倘若相互竞争,谁胜谁汰,是很难说的。 在一块肥沃的土地上,春天撤下了种子,不再耕耘,让嘉禾与杂草竞长,秋天去收获,一定会空手而回。嘉禾竞争不过杂草,任其自然,必然颗粒无收。在一座荒芜的海岛上,放进一群野猪、一群良种猪,过些年去看,野猪会繁殖成群,良种猪也许早死光了。
Natural selection is a natural phenomenon, the survival of the fittest is the result of choice and. The inevitable connection between the phenomenon and the result is called the law of nature. However, social phenomena are different from natural phenomena. After the superiority and inferiority of human choice, it is hard to say who will win the competition if they compete with each other. On a fertile land, the seeds were removed from the spring and no hard work was done. In this way, Golden Harvest competed with weeds for long and autumn to harvest, and it would surely go back empty-handed. Golden Harvest but competition weeds, let it be natural, inevitable particles confiscated. On a barren island, a group of wild boar, a group of breeding pigs, after years to see, the wild boar will multiply, the breeding pig may die early.
