Abstract

In the Cratylus, Plato criticizes the traditional rendering of Hades’ name as the ‘in-visible’ while in the Phaedo he endorses it. Despite this conflict, in both cases, the etymologies are used to oppose the negative characterization of this god by the tradition, just as prescribed in the Republic. Furthermore, both dialogues convey a similar description of Hades as an intellectual realm. Thus, there is an underlying conceptual coherence and a use of conflicting etymologies serving the same practical prescription. This article will verify if this scenario constitutes an instance of the serviceable lies presented in the Republic. Taking Hades’ different etymologizations as a case study, we will be able to better understand the justification for the pedagogical use of lies based on the complex interaction between souls with true and false beliefs. Two types of pedagogical lies emerge. Syrup lies characterize situations in which some true information is conveyed through an illegitimate but attractive cover such as etymologization or tales. In this way, they can capture the attention of souls who are hostage to false beliefs. Moreover, there is also the case for vaccine lies in which the illegitimate method used to convey some information has in itself a self-eroding element. Thus, those who receive the information are also encouraged to question the method in due course. After these determinations, it will be possible to evaluate how such a conception of lying scores morally.
