Abstract

The temptation to look for the “purely normative essence” of argument stems from the understandable ambition to distinguish rational persuasion from mere persuasion. But in seeking a purely normative notion of argument it is easy to overlook—or actually deny—that rational persuasion is a kind of persuasion. The burden of this essay is to show that the concept of reason from which our interest in argument derives can only exist and have normative force as a kind of persuasion, that is, as something causal.
