  1. Changing the theory of theory change: Towards a computational approach.Neil Tennant - 1994 - British Journal for the Philosophy of Science 45 (3):865-897.
    The Theory of theory change has contraction and revision as its central notions. Of these, contraction is the more fundamental. The best-known theory, due to Alchourrón, Gärdenfors, and Makinson, is based on a few central postulates. The most fundamental of these is the principle of recovery: if one contracts a theory with respect to a sentence, and then adds that sentence back again, one recovers the whole theory. Recovery is demonstrably false. This paper shows why, and investigates how one can (...)

  • Iterated Belief Change and the Recovery Axiom.Samir Chopra, Aditya Ghose, Thomas Meyer & Ka-Shu Wong - 2008 - Journal of Philosophical Logic 37 (5):501-520.
    The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy. We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection between iterated belief change and the axiom of recovery. We provide a representation theorem (...)
