How the Validity of the Parallel Inference is Possible: From the Ancient Mohist Diagnose to a Modern Logical Treatment of Its Semantic-Syntactic Structure

摘要

The purpose of this paper is to explore the issue of how the validity of the parallel inference (as a type of deductive reasoning) is possible in view of its deep semantic-syntactic structure. I first present a philosophical interpretation of the ancient Mohist treatment of the parallel inference concerning its semantic-syntactic structure. Then, to formally and accurately capture the later Mohist point in this connection for the sake of giving a general condition for the validity of the parallel inference, I suggest a modern logical treatment via an expanded predicate logic account.
