 The first book of the Rhetoric treats these three genres in succession. Rhetoric I.4–8 deals with the deliberative, I.9 with the epideictic, I.10–14 with the judicial genre. These chapters are understood as contributing to the argumentative mode of persuasion (logos) or — more precisely — to that part of argumentative persuasion that is specific to the respective genre of speech. The second part of the treatment of argumentative persuasion (logos) that is common to all three genres of rhetorical speech is treated in chapters II.19–26. The second means of persuasion, the one that works by evoking the emotions of the audience (pathos), is described in chapters II.2–11. Although the following chapters II.12–17 treat different types of character (êthos), these chapters do not, as one might infer, develop the first means of persuasion, i.e. the one that depends on the character of the speaker. The underlying theory of this means of persuasion is rather unfolded in a few lines of chapter II.1. The aforementioned chapters II.12–17 rather account for different types of character and their disposition to emotional response, which can be useful for speakers who want to arouse the emotions of the audience. Why the chapters on the specific (in the first book) and the common (in the second book) argumentative means of persuasion (logos) are separated by the treatment of emotions and character (in II.2–17) remains a riddle, especially since the chapter II.18 tries to give a link between the specific and the common aspects of argumentative persuasion — as though this chapter follows directly upon the end of Rhetoric I. Rhetoric III.1–12 discusses several questions of style (see below  § 8.1)  while Rhetoric III.13–19 is dedicated to the various parts of a speech and their arrangement.
