Multiple and iterated contraction reduced to single-step single-sentence contraction

Multiple contraction (simultaneous contraction by several sentences) and iterated contraction are investigated in the framework of specified meet contraction (s.m.c.) that is extended for this purpose. Multiple contraction is axiomatized, and so is finitely multiple contraction (contraction by a finite set of sentences). Two ways to reduce finitely multiple contraction to contraction by single sentences are introduced. The reduced operations are axiomatically characterized and their properties are investigated. Furthermore, it is shown how iterated contraction can be reduced to single-step, single-sentence contraction. However, in this framework the outcome of iterated contraction depends unavoidably on the order in which the inputs are received. This order-dependence makes it impossible to treat two inputs on an equal footing. Therefore it is often preferable to perform changes involving several pieces of information as multiple rather than iterated change.     

Coherence in Epistemology and Belief Revision*

A general theory of coherence is proposed, in which systemic and relational coherence are shown to be interdefinable. When this theory is applied to sets of sentences, it turns out that logical closure obscures the distinctions that are needed for a meaningful analysis of coherence. It is concluded that references to “all beliefs” in coherentist phrases such as “all beliefs support each other” have to be modified so that merely derived beliefs are excluded. Therefore, in order to avoid absurd conclusions, coherentists have to accept a weak version of epistemic priority, that sorts out merely derived beliefs. Furthermore, it is shown that in belief revision theory, coherence cannot be adequately represented by logical closure, but has to be represented separately. *Contribution to “Seven Bridges”     

Prospects for Epistemic Compatibilism

This paper argues that Sosa’s virtue perspectivism fails to combine satisfactorily internalist and externalist features in a single theory. Internalism and externalism are reconciled at the price of creating a Gettier problem at the level of “reflective” or second-order knowledge. The general lesson to be learned from the critique of virtue perspectivism is that internalism and externalism cannot be combined by bifurcating justification and knowledge into an object-level and a meta-level and assigning externalism and internalism to different levels.     

When “different” means “worse”: In-group prototypicality in changing intergroup contexts

An experiment with 213 participants provided evidence for in-group projection—the generalization of distinctive in-group attributes to a superordinate category. The frame of reference for in-group (German) judgments was manipulated by presenting either Italians or the British as an out-group. Results showed that attributes on which Germans differed from each out-group were accentuated not only in in-group judgments but also when judging Europeans. By adapting features of the superordinate category to those of the in-group, the in-group's similarity to, and the out-group's deviation from, the prototype of the superordinate category were maintained, if not emphasized. Further, higher in-group prototypicality—compared to out-group prototypicality—for the superordinate category was related to negative out-group attitudes. In-group projection was reduced when a complex representation of the superordinate category was primed.
