Purposiveness cannot, logically, be the mainspring for language development. 目的性在逻辑上不能当成语言发展的主要动力。
In this junction I do wish to point out that we do wish to recognize the subjectivity and its purposiveness of one system in interpreting the other system. 文至此际，笔者希望指出的一点是，我们确实希望在一个系统诠释另一系统时能认识到其主体性及目的性。
