To Preference via Entrenchment

TL;DR

The paper introduces partial entrenchment, a generalization of epistemic entrenchment, and demonstrates how preferential inference can be derived as its skeptical counterpart, offering a new perspective on inference mechanisms.

Contribution

It proposes partial entrenchment as a novel generalization and links it to preferential inference, expanding the theoretical framework of epistemic reasoning.

Findings

Partial entrenchment generalizes epistemic entrenchment.

Preferential inference can be derived from partial entrenchment.

The approach offers a new perspective on inference mechanisms.

Abstract

We introduce a simple generalization of Gardenfors and Makinson's epistemic entrenchment called partial entrenchment. We show that preferential inference can be generated as the sceptical counterpart of an inference mechanism defined directly on partial entrenchment.
