This is a linguistic science essay on the most complex and least understood rhetorical resource, The Rhetorical Resource Irony, observes the phenomenon in its original ancient Greek form, analyzing Plato's Euthydemus as a sample of Socratic irony in its original context, and then devotes itself to a detailed examination of Candide or Optimism and the tales Memnon or Human Wisdom and History of Escarmentado's Travels Written by Himself by Voltaire.
There is an attempt to understand the semantic modifications that the rhetorical resource irony has undergone over time and how it operates in the construction of satire and refined humor.
Written from a real, traditional Catholic, non-ideological perspective, the book offers a necessary historical contextualization of Voltaire's education and a reading of his relationship with Leibniz's faith and philosophy, the target of much of his irony. It is not a generic introduction to the subject, but an authorial essay that articulates philology through synchronic, diachronic and literary analysis.
