REALISMO, NOMINALISMO E CARTESIANISMO: SENTIDO E NATUREZA DAS IDEIAS COMO REPRESENTAÇÕES DO MUNDO.

The approach about the ideas, understood as metal representations, has practically bookmarked the whole Philosophy History, since the ancient Greece to the contemporary period. A lot of interpretations have been given to the meaning and to the nature of the ideas by many schools, among them lots of Realism slopes. This paper aims to present, from a historical and epistemological fragment, some theoretical perpectives, with emphasis in the realistic, nominalist and Cartesian proposals in relation to the formation and nature of the ideas.
