Gottlob Frege: os sentidos lógicos e psicológicos nas sentenças da linguagem natural

The main purpose of this article is to analyze Frege's semantic theory for natural language sentences and the mental processes associated with their meaning. Frege's main support is the analysis of language to distinguish in the human mind the logical elements and the psychological aspects. Therefore, our investigation aims to present in Frege's writings the presence of a semantic theory related to the aesthetic charm of poetic art and another logic or associated with scientific investigations.
