This lecture considers two meanings of the term ""end."" It re-examines, from Lecture 5, how controversies begin by studying the conditions under which they end, but most of the lecture concerns ""end"" in the sense of the larger purposes that are served by the process of argumentation. Argumentation helps achieve the goals of a democratic society by cultivating the skills of critical thinking, reflective judgment, and active participation that are vital to the maintenance of a robust public sphere.
