Abstract

This paper discusses the meaning of expressed preference statements. A holistic explanation of preferences is proposed: preference relations between propositions are explained by preference relations over worlds. Only those world-preferences function as explanans which are maximally similar to the actual world, and which are maximally similar to each other. The concept of similarity as intuitive is rejected, and is interpreted instead with reference to causal structure: 'closest to the actual world' is interpreted as compatible with the causal structure of the actual world, and 'most similar to each other' as sharing the same causal background conditions.
