Charity for moral reasons? – A defense of the principle of charity in argumentation

Abstract In this paper I argue for a pro tanto moral duty to be charitable in argument. Further, I argue that the amount of charitable effort required varies depending on the type of dialogue arguers are engaged in. In non-institutionalized contexts, arguers have influence over the type of dialogue that will be adopted. Arguers are therefore responsible with respect to charity on two levels: First, they need to take reasons for charity into account when determining the dialogue-type. Second, they need to invest the amount of effort towards charity required by the dialogue-type.
