Comparative Study On Wittgenstein And Jin Yuelin’s Logical Truth Thoughts

The“Tractatus Logico-Philosophicus”represents wittgenstein’s early philosophythoughts. He used two chapters(in total seven chapters) discussed the theory of truthfunction in details. It contains the inevitable logical truth thought of tautologies. JinYuelin’s early thought is mainly reflected in the On Dao, Logic and The theory ofknowledge. Among them, the Logic is devoted to the logic of his research, including asummary overview of traditional logic and a pioneering exploration of modern logic. Thefourth part of the book is about the logic of the system research, this part is the bestembodies his "exhaustive possible" inevitable logic of truth thought. This paper mainlycompares the two logical truth thought.Their thoughts on logical truths have similarities and differences. They all started outas a demonstration about the fundamental propositions. They considered a logical truth is"disjunctive arranged all possible," after exhaustive all these "possible", is "inevitable",must be true.Their researches of logic truth consists mainly in the two-valued logic system,they think a fundamental proposition have true or false. By fundamental propositionsconstitute a complex proposition, there are2npossibilities, one of which must betautologies, one of which is the contradiction, the propositions that the arrangementconstitutes tautologies extract obtained is inevitable true.Their thoughts on logical truths also has a lot of different. For example, Wittgensteinconstructed truth table, using it can visually display proposition as true or false. Hislogical truth contains the optimal paradigm of thought in modern logic. While Jin Yuelinwidened the "exhaustive possible" logical truth thought. He thought it not only applies totwo-valued logic system, but also applies to some other logic systems. Unfortunately, hedid not conduct a detailed discussion in this aspect. In addition, their logic truth thoughtsis closely related with their philosophy. Studied their philosophy benefit we understandtheir logic truth of thought. Conversely, we can also understand their philosophy of logicaltruth from their Philosophy thought. So this paper also compares their philosophy in orderto better understand the differences in their thoughts on logical truths.
