文章以远古西亚地区计数方式的演变为例来分析抽象能力的发展。陶筹表明人类计数方式最初是通过具体的一一对应的方式实现的。公元前7500年的西亚陶筹表现其所代表物品的方式却是抽象的,比如以锥形陶筹表示谷物量器。公元前3300年,人们开始用空心泥球来保存有计数功能的陶筹,以更为抽象的符号刻画在其表面来记录其内封存的陶筹。这个过程发展到最高阶段便产生了具有抽象意义的数字,随后文字也就应运而生。
The article analyzes the evolution of abstraction ability by taking the evolution of counting methods in ancient West Asia as an example. Pottery chips show that the way human counting was originally achieved through concrete one-to-one correspondence. The way in which Western Asia Pottery raised its representations in 75 BC is abstract, such as the use of conical pots to represent grain measurers. In 3300 BC, hollow clay balls were used to preserve the pottery with counting functions, and the more abstract symbols were portrayed on the surface to record the sealed pottery. As the process progressed to the highest stage, abstract figures were produced, and the texts came into being.
