Sobre a concepção de ciência natural do Tractatus

Abstract

The objective of this paper is to elucidate Wittgenstein’s conception of natural science, according to Tractatus Logico-philosophicus. In the first place, we will deal with the concepts of picture and proposition, in order to clarify the bases of the language logical analysis, as presented in this book. According to analysis of language as picture, every proposition has a meaning, or, in other words, can be either true or false. Language radicalization, as a logical model through which reality is presented, substantiates the concept of natural science as a model that serves as a hypothesis to describe the world. In order to do so, natural science should be in the field of what can be said, in the field of meaning. Therefore, its laws and principles should be in accordance with logical rules that guarantees internal logical coherence to the system and its generality but they should also permit the construction of propositions that represent the facts. This work intends to explain that the language of natural science, according to the Tractatus theory, is the result of the language theory concept as picture.
