Abstract
The Rhetoric to Alexander (second half of the fourth century B.C.) is among the oldest contributions to the study of argumentation. From antiquity on, this treatise, which abounds in opportunistic advice, has come under heavy criticism on normative grounds. And yet, as I shall maintain here, it clearly takes into account the requirements of rational argumentation which are still in use today. Moreover, it contains the seeds of a whole series of doctrines found in modern normative argumentation theory. There are reasonable grounds for maintaining that some of these modern doctrines stem indirectly from the tradition to which the Rhetoric to Alexander belongs
