World·Language·Unspeakable

This is the interpretation of Tractatus Logico-Philosophicus which is the early important works of Wittgenstein. Follow the logical order of Wittgenstein’s writing a book, it attains step by step to his last proposition, "What we cannot speak about we must pass over in silence.(7) ". But before this, we should begin with his opinion about the world firstly. The opinion means ontology about the World. He discusses how the nature ontology of the physical world constitute the entire real world through the object gradually build state of affairs; After then he discusses his cognition about the logic forms of the whole world, the relationship that the fact can depicts another and the picture theory which means the pictorial form is the same to logical. we can undstanding the true concept of the pictorial form form the perspective of the potential or possibility; In the final of the first part, there is a review refer to his opinion about the world from the perspective of philosophy history in the part which is about illustration of the world ontology. Especially we discuss the issue of the logical completeness and certain feature through the comparison his philosophy and other thinkers highlights which is in history of philosophy. In the second part we further forward to the ideas and propositions, through discussion the propositions and exploration of of elementary propositions we can understand the general form of propositions which based on the truth-operations of elementary propositions. Ultimately elementary propositions depend on its unique truth-operation to achieve the general form of a proposition, and are gradually accumulated to explain the whole reality of the world. From this he conclude the boundaries of language and the boundaries of the whole world simultaneously. The last part we will illustrate the mysterious domain which is outside the boundaries of the language or the world.This is the purpose of Wittgenstein. But he illustrates this issue through his own unique way. the seventh propositions can be said "finishing touch",it is the destination of all propositions before. He is not directly draw boundaries through the world, but through the demarcation of language. This is another important feature of his philosophy and is the one of this paper’s highlights.
