The relation between chance and actuality gives rise to a puzzle. On the one hand, it may be a chancy matter what will actually happen. On the other hand, the standard semantics for ‘actually’ implies that sentences beginning with ‘actually’ are never contingent. To elucidate the puzzle, I defend a kind of objective semantic indeterminacy: in a chancy world, it may be a chancy matter which proposition is expressed by sentences containing ‘actually’. I bring this thesis to bear on certain counter-examples, proposed by Hawthorne and Lasonen-Aarnio, to Lewis' ‘principal principle’

This paper explores the possibility of supplementing the suppositional view of indicative conditionals with a corresponding view of epistemic modals. The most striking feature of the suppositional view consists in its claim that indicative conditionals are to be evaluated by conditional probabilities. On the basis of a natural link between indicative conditionals and epistemic modals, a corresponding thesis about the probabilities of statements governed by epistemic modals can be derived. The paper proceeds by deriving further consequences of this thesis, in particular, the logic of epistemic modals and their logical interaction with indicative conditionals are studied.

The current debate about peer disagreement has so far mainly focused on the question of whether peer disagreements provide genuine counterevidence to which we should respond by revising our credences. By contrast, comparatively little attention has been devoted to the question by which process, if any, such revision should be brought about. The standard assumption is that we update our credences by conditionalizing on the evidence that peer disagreements provide. In this paper, we argue that non-dogmatist views have good reasons to reject conditionalization. Instead, peer disagreements should be understood to call for a revision of our prior conditional probabilities: rather than merely adding to our original evidence, they pose a challenge to the thought that we have properly assessed the probative force of our original evidence
