Restating an interlocutor’s position in an incredulous tone of voice can sometimes serve legitimate dialectical ends. However, there are cases in which incredulous restatement is out of bounds. This article provides an analysis of one common instance of the inappropriate use of incredulous restatement, which the authors call “modus tonens.” The authors argue that modus tonens is vicious because it pragmatically implicates the view that one’s interlocutor is one’s cognitive subordinate and provides a cue to like-minded onlookers that dialectical opponents (...) are not to be treated as epistemic peers.

There is a tension with regard to regulative norms of inquiry. One’s commitments must survive critical scrutiny, and if they do not survive, they should be revised. Alternately, for views to be adequately articulated and defended, their proponents must maintain a strong commitment to the views in question. A solution is proposed with the notion of holding one’s own as the virtue of being reason-responsive with the prospects of improving the view in question.

Virtue theories of argumentation (VTA) emphasize the roles arguers play in the conduct and evaluation of arguments, and lay particular stress on arguers’ acquired dispositions of character, that is, virtues and vices. The inspiration for VTA lies in virtue epistemology and virtue ethics, the latter being a modern revival of Aristotle’s ethics. Aristotle is also, of course, the father of Western logic and argumentation. This paper asks to what degree Aristotle may thereby be claimed as a forefather by VTA.
