Cross-disciplinary influences
Artificial intelligence
Since reasoning with defeasible arguments seems to lead to successful behavior of people, artificial intelligence researchers try to capture its essence (e.g., Nute, 1988; Geffner and Pearl, 1992; Simari and Loui, 1992).
Epistemology
Questions about justification and support of beliefs have resulted in formal epistemological theories (e.g., Loui, 1987, 1991; Pollock, 1987-1995).
