Esquerda e Direita no Brasil: uma análise conceitual

"After having a central role, during a great part of the XX century, as an explanatory system for political parties, the right/left scale is going through a revaluation of its explanative potential in the last 20 years. However, this tendency towards a weakening (or reconfiguration?) of this scale does not have the same causes in all countries. Besides having had a great variation throughout history, the definition of left and right also varies according to the historical and cultural context of each country. The aim of this paper is to describe the main elements constituting these concepts on national and international bibliography. The applicability of the Manifestos Research Group`s scale to the Brazilian political parties is also discussed, and more fruitful categories to analyse this party system are debated."
