The distinction between argument and persuasion has some historical significance insofar as it is the basis of the distinction between logic and rhetoric as they are traditionally understood — logic choosing argument as its focus, rhetoric choosing persuasion. This being said, the distinction between persuasion and argument remains an elusive one when one considers the arguments one finds in informal discourse. Certainly it must be said that appeals to emotion and character play a significant role in ordinary arguments that occur in social, moral and political contexts.
Within informal logic, the key argument schemes discussed include arguments from authority, causal reasoning, arguments by analogy, and various forms of moral argument.
In looking for ways to account for the features of argument that are not captured by traditional logical conceptions, informal logicians have turned to rhetorical traditions.
The relevance of rhetorical analysis to informal logic is emphasized by Tindale (1999, 2004, 2010), who advocates an approach to informal logic that incorporates traditional rhetoric.
