The aim is to understand if, how and what linguistic means was are used in the posts through Aristotle’s triangle of rhetoric. His theory consists of the three appeals: ethos, logos and pathos. These three appeals all holds a number of individual features.  with a perspective from classic rhetoric, namely Aristotle’s triangle of rhetoric. The persuasion was examined using Aristotle’s triangle of rhetoric and its appeals ethos, logos, and pathos. The research was carried out by classifying the posts by the three appeals and their features. These defined what linguistic means were used and how. All three appeals are equally important when persuading an audience  public through a text as they are necessary to raise an understanding and interest to the text’s focus. Aristotle argued that when including all three appeals, the text has reached its full extent potential of persuasion. The appeals have their unique attributes and may also persuade when used individually. The An author’s credibility and trust applies to the appeal ethos, logic and reasoning in a of the text applies to logos, and a text that moves its reader’s emotions applies to pathos.

Cette thèse a pour objectif d’étudier la tragédie du XVIIe siècle en France avec la notion de faute tragique, hamartia, et de montrer l’originalité et la diversité des tragédies classiques. Commentée dans la Poétique d’Aristote, l’hamartia se définit comme une notion médiane entre un délit volontaire et une malchance. Coupable d’une hamartia, le héros n’en est pas pour autant entièrement responsable malgré sa prise d’initiative, dans la mesure où la faute n’est pas due à l’intention perverse. Parce que le malheur déclenché par une hamartia, apparaît disproportionné à l’intention du coupable, les spectateurs éprouvent de la compassion envers le héros infortuné. Dans la mesure où la compassion est une des émotions essentielles de la tragédie au même titre que la terreur – en effet, la catharsis consiste en l’épuration de ces émotions –, la faute tragique constitue à cet égard un des composants sine qua non de la tragédie. Mais arrivée au XVIIe siècle en France, la faute garde-t-elle le même statut ? Pour répondre à cette question, nous examinons les tragédies de sept dramaturges, Alexandre Hardy, Pierre Du Ryer, Jean Rotrou, Tristan L’Hermite, Pierre Corneille, Jean Racine et Jean-Galbert de Campistron, ce qui permet d’étudier le XVIIe siècle en entier. Le premier chapitre sera consacré à l’examen de la notion de faute dans les écrits théoriques. Dans le deuxième chapitre, nous nous intéresserons à la fabrique du héros coupable. Le troisième chapitre portera sur la nature de la faute. Et nous étudierons, dans le quatrième chapitre, le statut de la faute sur le plan dramaturgique, avant d’examiner, dans le dernier chapitre, les problèmes moraux. Ce travail révèlera l’importance de la Poétique d’Aristote dans la tragédie du XVIIe siècle en France. / The purpose of this doctoral thesis is to study the French tragedy in the seventeenth century researching into the notion of tragic flaw, hamartia, and to show the originality and the diversity of the French classical tragedy. This notion, commented by Aristotle in "Poetics" originally differs from either an intentional crime or an accidental one. The tragic flaw presupposes the participation of an agent without denying the presence of fortuity. Although a tragic hero is responsible for his misfortune, as it proceeded from his fault, the result exceeds his intention. And this disparity between intention and misfortune makes the audience feel compassion for the hero suffering from his misfortune. If this compassion is one of the emotions caused only by tragedies, the tragic flaw constitutes in this respect an essential element of tragedy. But is the concept of fault identical in the Christendom society of the seventeenth century? To answer this question, I deal with the tragedies of seven dramaturges, Alexandre Hardy, Pierre Du Ryer, Jean Rotrou, Tristan L’Hermite, Pierre Corneille, Jean Racine and Jean-Galbert de Campistron, to cover the seventeenth century. In the first section of this work, I examine the notion of fault in the theoretical texts. The second section consists in studying the tragic figure. The third section is about the nature of the fault, the private fault and the politic fault. The fourth section concerns the status of fault on the dramaturgical level, before examining moral questions in the final section. This work reveals the importance of Aristotle’s Poetics in the French tragedy of the seventeenth century.
