Abstract

Conditional credence is an important concept in many areas of philosophy. However, little consensus has been achieved regarding its semantics and ontology. In this thesis I shall sketch a contextualist suppositional account of conditional credence by drawing insights from two seemingly disjoint debates: the foundational debate on the relationship between conditional and unconditional probabilities, and the semantic debate on the relationship between conditional probability and probabilities of conditionals. I argue that, for a given pair of propositions A and B, the conditional credence one ought to have for B given that A - P(B|A) - may depend on contextual parameters like the way in which we mentally represent the extensions of as well as the stochastic relationships between A and B.
