Resumen:
Abstract. We compare two conditional logics for defeasible inference: Alchourróns defeasible logic DFT and Boutiliers CO logic. The two logics share the distinguishable characteristics common to most logics for defeasible inference. Namely, their conditional connective defeat the rules of Modus Ponens, Strengthening the Antecedent, Transitivity, and Contraposition. Although both logics have possible worlds semantics, Boutiliers is relational while Alchourróns is non-relational. In this note we reveal the connection between the two, concluding that the conditional sentences validated by both logics are precisely the same.
