“不具备足够的根据,没有一个命题和没有一个理论是可以接受的。”这是科学研究的一条基本原则。所谓足够的根据,应当像公认的亚里士多德那样,对一个命题的提出,要进行连续性的追问其学理根据何在,一直追问到像数学中的那种无须证明的公认之理,即公理为止。文学理论的创新之论也该如此。本文就人物性格的模糊性这一重要的文字问题为例,对它的科学原理,以及原理背后的数学性的公理分别加以解析。 “There is no sufficient basis, no proposition and no theory is acceptable.” "This is a basic principle of scientific research. The so-called sufficient basis should be as recognized as Aristotle, put forward a proposition, it is necessary to carry out a continuous questioning its basis for the theory, has been asking like mathematics in the kind of unconfirmed recognized reason that Axiom so far. The same goes for the theory of innovation in literary theory. This article, on the important textual issue of the character’s vagueness as an example, analyzes its scientific principle and the mathematical axioms behind the principle respectively.
