I have argued that argumentation theorists should concern themselves with scientific argument as a source for images of epistemic virtue in argument. In this paper I will contrast the lessons learned from this endeavour with their counterpart in the evaluation of political arguments. Despite obvious differences, fundamental symmetries between the two argumentation cultures point to the need for a more serious engagement with rigorous disciplinary arguments in argument theory.

This paper looks at the attack on scientific racism in the 20th century by a group of social and biological scientists. I will utilize the apparatus of my model of emerging truth to show how even in complex socially conditioned argumentation the ultimate virtue is seeking the truth through increasingly powerful logical connections and deeply embedded warrants.
