國立臺灣大學哲學論評

Abstract /

This paper will do two things. First to argue that the logical connectives are used to express mental acts, to do speech acts and prepositional acts. They are used to expiree prepositional ties. Second, from the first things to say that every sentence or proposition must contain at least one logical connective, and every relation must intrinsically contain a direction. Several relevant theories are also examined.
