In Discussing Manifestation Of Inexpressible Thing In Tractatus Logico-philosophicus

In order to get access to what can not be said, this paper firstly deals with the concepts of the world, fact, and object in Tractatus Logico-philosophicus. Tractatus Logico-philosophicus starts from the concept of the world, so does this paper. The world is the totality of facts, which are combinations of objects, and the possibilities of the combinations have been contained within objects themselves. After giving the structure of the world, we turn into the picture theory, which deals with the relationship between language and the world. According to Wittgenstein, language is a picture of the world, and there is a kind of isomorphic relationship between language and reality. The elements of language and those of reality are corresponded one by one with each other, and they are respectively combined in the same structural form.The world determines a picture with regard to what the picture is about, and the picture, with regard to how the picture does, is independent of the world, because it depicts the world based upon what it is. And from those two perspectives, a picture has both intentionality and internality, and the former is even more important. Taken as a kind of intentional behavior, a picture must have non-reflexivity, which means its intentional behavior can not be regard as its intentional object. Due to its non-reflexivity, a picture can not present its own intentional behavior. Proposition,being a kind of pictures, also can not present its own intentional behavior. Therefore,we can draw the conclusion that the necessary condition for a propositional behavior is what can not speak about. So far, we get access to what can not be said in Tractatus Logico-philosophicus. What we cannot speak about we must pass over in silence, but it makes itself manifest. It is precisely in the process of using proposition that the necessary condition for propositional behavior show itself forth, since it has all along been the precondition. Many things that can not be said are mentioned in Tractatus Logico-philosophicus, but among them only logical form is clearly articulated, so this paper also focuses on the concept of logical form. Logic is the regularity and constraint of a propositional behavior, which is established spontaneously by the behavior on its own purpose. Logic does not have any external objective. It is our willthat initially brings us into logic. For Wittgenstein, Logico-philosophicus is a work of ethics, and he aims at reaching a settlement between human beings and the world by setting limits for human knowledge. In the view of Wittgenstein, what can not be said is far more important than what can be put into words. This view is of far-reaching significance.
