Noções preliminares para uma classificação lógica em linguagem natural

Abstract

Establishing rules and chains between objects and properties is a necessary condition for a logical classification. The first step to rationalize classification instruments, based on logic, is understood as preliminary notions present both in Aristotelian logic and in Philosophy. In this sense, the current article reviews the three pairs of fundamental terms: i) particular and universal and their divergences about the world of things and the world of language; ii) genera and species; iii) extension and intension, through critical reading in Philosophy texts. It highlights the importance of the realist doctrine in the construction of ontological instruments in Natural Language.
