The rules of the rationality of practical discourse in the light of ethics of discourse: An analysis of Robert Alexy’s proposal

The author discusses the rational argumentation of the values from a proposal defended by the legal philosopher Robert Alexy. The paper shows that discourse for Alexy is essentially a regulated activity. A model of certain rules ensure the rationality and correctness of practical discourse oriented towards resolving conflicts of value. Firstly, the types of rules responsible for the rationality of practical argumentation are described. Secondly, some open problems relating to the claim to correctness of reasoned practical discourse are posed, namely problems derived from the idea of consensus and that of a single correct answer to certain practical issues that include conflicts of values and raise basic disagreements.
