Rationality, Judgment, and Argument Assessment

Argument, Discussion and Rationality

When applying argumentation theory for purposes of what to believe or what to do, the idea is to follow a three-step process. In the first step, one starts with a particular knowledge base and determines what are the possible defeasible derivations (called arguments) one can make using this knowledge base. These derivations then become the nodes of a directed graph called an argumentation frame...

Kant on the Rationality of Moral Judgment

Judgment aggregation without full rationality

Several recent results on the aggregation of judgments over logically connected propositions show that, under certain conditions, dictatorships are the only propositionwise aggregation functions generating fully rational (i.e., complete and consistent) collective judgments. A frequently mentioned route to avoid dictatorships is to allow incomplete collective judgments. We show that this route d...

kant on the rationality of moral judgment

the paper deals with kant's conception of moral judgment. i start by criticizing a dominant interpretation of kant's practical rationality in its assertion that choosing, i.e. exercising judgment consists in adopting a maxim; and adopting a maxim is equivalent to acting on a principle, giving oneself the moral law (korsgaard). according to this view, the logical inescapability of choo...

Judgment aggregation without full rationality: a summary

Several recent results on the aggregation of judgments over logically connected propositions show that, under certain conditions, dictatorships are the only independent (i.e., propositionwise) aggregation rules generating fully rational (i.e., complete and consistent) collective judgments. A frequently mentioned route to avoid dictatorships is to allow incomplete collective judgments. We show t...
