If the point of argument is to produce conviction, an argument tor a foregone conclusion is pointless. I maintain, however, that an argument makes a variety of cognitive contributions, even when its conclusion is already believed. It exhibits warrant. It affords reasons that we can impart to others. It identifies bases tor agreement among parties who otherwise disagree. It underwrites confidence, by showing how vulnerable warrant is under changes in background assumptions. Multiple arguments for the same conclusion show how our beliefs hang together.

Cognitive advancement is not always a matter of acquiring new information. It often consists in reconfiguration--in reorganizing a domain so that hitherto overlooked or underemphasized features, patterns, opportunities, and resources come to light. Several modes of reconfiguration prominent in the arts--metaphor, fiction, exemplification, and perspective--play important roles in science as well. They do not perform the same roles as literal, descriptive, perspectiveless scientific truths. But to understand how science advances understanding, we need to appreciate the ineliminable cognitive contributions of non-literal, non-descriptive symbols.
