Evidence and conceptual change

Abstract

In this paper we shall formulate a rule of evidence that is based on subjective probabilities and is sensitive to conceptual change. Whether a sentence is selected as evidence on our account will be determined by the subjective probability of the sentence and of the sentences with which it competes for evidential status. Both the subjective probability of a sentence and what sentences it competes with will depend on the conceptual and semantic relations among sentences of the language. When these relations are altered, new sentences may be added to evidence and old ones deleted.
