  1. Willem A. Labuschagne & Johannes Heidema (2005). Natural and Artificial Cognition: On the Proper Place of Reason. South African Journal of Philosophy 24 (2):137-149.score: 960.0
    We explore the psychological foundations of Logic and Artificial Intelligence, touching on representation, categorisation, heuristics, consciousness, and emotion. Specifically, we challenge Dennett's view of the brain as a syntactic engine that is limited to processing symbols according to their structural properties. We show that cognitive psychology and neurobiology support a dual-process model in which one form of cognition is essentially semantical and differs in important ways from the operation of a syntactic engine. The dual-process model illuminates two important events in (...)

    We model three examples of beliefs that agents may have about other agents’ beliefs, and provide motivation for this conceptualization from the theory of mind literature. We assume a modal logical framework for modelling degrees of belief by partially ordered preference relations. In this setting, we describe that agents believe that other agents do not distinguish among their beliefs (‘no preferences’), that agents believe that the beliefs of other agents are in part as their own (‘my preferences’), and the special (...)

  3. Thomas Andreas Meyer, Willem Adrian Labuschagne & Johannes Heidema (2000). Infobase Change: A First Approximation. [REVIEW] Journal of Logic, Language and Information 9 (3):353-377.score: 900.0
    Generalisations of theory change involving operations on arbitrary sets ofwffs instead of on belief sets (i.e., sets closed under a consequencerelation), have become known as base change. In one view, a base should bethought of as providing more structure to its generated belief set, whichmeans that it can be employed to determine the theory contraction operationassociated with a base contraction operation. In this paper we follow suchan approach as the first step in defining infobase change. We think of an infobase (...)

  5. Katarina Britz, Johannes Heidema & Willem Labuschagne (2009). Semantics for Dual Preferential Entailment. Journal of Philosophical Logic 38 (4):433 - 446.score: 450.0
    We introduce and explore the notion of duality for entailment relations induced by preference orderings on states. We discuss the relationship between these preferential entailment relations from the perspectives of Boolean algebra, inference rules, and modal axiomatisation. Interpreting the preference relations as accessibility relations establishes modular Gödel-Löb logic as a suitable modal framework for rational preferential reasoning.

  6. Thomas Meyer, Johannes Heidema, Willem Labuschagne & Louise Leenen (2002). Systematic Withdrawal. Journal of Philosophical Logic 31 (5):415-443.score: 450.0
    Although AGM theory contraction (Alchourrón et al., 1985; Alchourrón and Makinson, 1985) occupies a central position in the literature on belief change, there is one aspect about it that has created a fair amount of controversy. It involves the inclusion of the postulate known as Recovery. As a result, a number of alternatives to AGM theory contraction have been proposed that do not always satisfy the Recovery postulate (Levi, 1991, 1998; Hansson and Olsson, 1995; Fermé, 1998; Fermé and Rodriguez, 1998; (...)

  7. Thomas Andreas Meyer, Willem Adrian Labuschagne & Johannes Heidema (2000). Refined Epistemic Entrenchment. Journal of Logic, Language and Information 9 (2):237-259.score: 450.0
    Epistemic entrenchment, as presented by Gärdenfors and Makinson (1988) and Gärdenfors (1988), is a formalisation of the intuition that, when forced to choose between two beliefs, an agent will giveup the less entrenched one. While their formalisation satisfactorilycaptures the intuitive notion of the entrenchment of beliefs in a number ofaspects, the requirement that all wffs be comparable has drawn criticismfrom various quarters. We define a set of refined versions of theirentrenchment orderings that are not subject to the same criticism, andinvestigate (...)
