Abstract. When reformulated as a modal logic for conditional belief, the main properties of adaptive logics can be captured as properties of the resulting modal operators. The purpose of the present paper is to give a broadly epistemic interpretation to these modalities, and use these to bring out the distinctive epistemic character of adaptive logics. Concretely, I want to do three things: (a) give a brief description of a modal logic for conditional belief based on the semantics of adaptive consequence; (b) investigate the role of logical and epistemic or doxastic possibilities in this logic; and (c) show how these modalities can be used to elucidate the relevance of logic for deductive reasoning.
