试谈同形与递归

Lexically Identical Elements in the Clause: With Particular Reference to Recursion

本文讨论出现于同一小句之中的同形形式,着重探讨与递归相关的现象。文章通过小句中的同形形式特别说明:上古汉语反映有当时的抽象思维,尤其一些体现充足理由律的句子反映出当时的抽象推理。但是,抽象推理并不是一味的无穷后退,有循环才是好的形式,即要体现"正—反—合"的辩证法。此外,本文还说明:这类同形递归形式有的涉及认知与言说,反映出不同程度的怀疑主义。

Repetition of a lexical element in one clause is normally avoided. Nevertheless, lexically identical elements in one clause are indeed attested in classical Chinese texts, and sometimes related to recursion. This kind of clause, including both lexically identical elements and recursion, shows that there already existed abstract reasoning as reflected in classical Chinese. But abstract reasoning is not equal to infinite regression, and only that with cyclicity could be a good one, that is, it should represent the thesis-antithesis-synthesis dialectics. The clause with recursive lexically identical elements may involve cognition and speaking, and even display scepticism of various degrees.
