对象、可能世界与必然性 —《逻辑哲学论》的本体论分析

This article focuses on several important but obscure concepts in Tractatus Logico-Philosophicus. In order to clarify the concept of “object”, I compare it with “atom”. The analysis of the two concepts explains two important questions which have confused Wittgenstein’s reviewers for long: why is the world not the totality of things? Is object substance? “Logical space” is an important concept in Tractatus Logico-Philosophicus, although it only appears several times. If a proposition serves as the coordinates in the logical space, what are the coordinate axes? Is a possible world a point in the logical space, or a set of points in it? Based on symbolic transformations, I suggest that possible worlds serve as coordinate axes in the logical space. The concept of “possible worlds” contradicts with “necessity”. In Wittgenstein’s theory, all possible worlds are “accessible” to one another. This is why Wittgenstein fails to cope with the conflict between “possibility” and “necessity”.
