What is Logical Pragmatics
From “Argument as Reasoned Dialogue¨ in Informal Logic
Logical theory traditionally has tended to emphasize semantic relationships, that is, relationships between sets of true or false propositions […]. Logical pragmatics has to do with the use of these propositions by an arguer to carry out a goal of dialogue in reasoning with a second participant in the dialogue. One common and important type of goal is to successfully convince or persuade another arguer with whom the first arguer is engaged in reasoned dialogue.
Logical theory, if it is semantic logical theory, analyzes the relationships between true or false propositions; whereas logical pragmatics analyzes, evaluates or examines the utility of given propositions for some goal in a dialogue. In other words (Walton 2008, 2-3):
From “Argument as Reasoned Dialogue¨ in Informal Logic
Logical semantics then, is centrally concerned with the propositions that make up an argument. Logical pragmatics is concerned with the reasoned use of those propositions in dialogue to carry out a goal, for example, to build or refute a case to support one’s side of a contentious issue in a context of dialogue.
