Does study of animals help us to learn human nature?(2007.10.27) Human nature is defined as a set of characteristics, including ways of thinking, feeling and acting, that are shared by all normal human beings. Two connotations are contained in this definition. First, human nature is shared by all normal people. Second, no other species have the characteristics that define human nature. In other words, the characteristics considered as human nature are not possessed by other species. Therefore, to understand human nature, we have to make clear in what aspects we human beings are unique. Compare and contrast human beings with other species, largely animals are effective ways to understand this question. So study of animals helps us to learn human nature. Communicating with language and making use of tools are regarded as one characteristic included in human nature. There was once a debte(debate) in academic circle whether these the characteristics of human beings' are unique comparing to other animals. It is found that some birds can also speak "language" through training. For example, parrots can imitate human voice and utter simple phrases like "Good morning, master" if trained in a proper way. Besides, bees communicate within group through a special dance. They dance to tell other bees where and how far away the flowers are. These findings casted doubts to the assertion that only human beings can speak language, thus questioning whether communicating through language is human nature. The doubts were cleared in the furhter study of these animals. Close study of parrots shows that although parrots can pronounce certain words, phrases or even short sentences. They have no idea of the meanings conveyed. The act of uttering language-like sounds is simply a mechanical imitation, through which communication can not be achieved. As a result, what parrots say is not language. Language is an endowment that only human beings have. As for bees' dancing, scientists, after long time observation, find the patterns of their dances. Although bees' dancing do serve as a kind of communication, this communication is quite limited. Except for telling others the whereabout of foods, bees cannot communicate other information. Humans use language to communicate various things in life, including events, people, animals, feelings, etc. Compared to human language system, the limited communicative function of bees' dancing makes it impossible to be called "language". From the above discussion, we can see clearly that in order to understand human nature, we have to study animals. Careful examination of the similarities between other species and human beings help to obtain more sophifisticated(sophisticated) understanding of the unique properties of humans. |
