Kant, Chomsky e Rawls: sobre o método de "A Theory of Justice"

Resumo

The aim of this paper is to critically examine Rawls’ discussions of the method of a moral theory spread through his book A Theory of Justice. First, Kant’s reasons for rejecting the attempt to employ in philosophy a method inspired in mathematics, respectively, in geometry are considered. This provides a basis for rejecting the interpretation given by Maria Carolina and Zeljko Loparic, according to which Rawls would have allegedly followed Kant’s indications, and applied methodological developments of the Greek geometry to the solution of philosophical problems. Second, a brief analysis of some passages in Rawls’ book is given from which it becomes clear that despite his references to several methodological guidelines his real inspiration comes from Chomsky’s linguistics. The aims and method of Chomsky’s linguistics is then discussed to show the parallelism between them and Rawls’ own statements on the aims and method of his moral theory. Finally, it is argued that the purported parallelism collapses because, among other things, the data of a philosophical moral theory are completely different in nature from the data in linguistics.
