The role of possible worlds in philosophy is hard to overestimate. Nevertheless, their nature and existence is very controversial. This is particularly serious, since their standard applications depend on there being sufficiently many of them. The paper develops an account of possible worlds on which it is particularly easy to believe in their existence: an account of possible worlds as pleonastic entities. Pleonastic entities are entities whose existence can be validly inferred from statements that neither refer to nor quantify over (...) them as a matter of conceptual necessity. Definitions are proposed that ensure that this is the case for possible worlds. (shrink)

The article is an extended comment on Strawson’s neglected paper ‘Maybes and Might Have Beens’, in which he suggests that both statements about what may be the case and statements about what might have been the case can be understood epistemically. We argue that Strawson is right about the first sort of statements but wrong about the second. Finally, we discuss some of Strawson’s claims which are related to positions of Origin Essentialism.

As philosophers are keen to say, there is a possible world where Socrates is a carpenter. Plausibly, truths about what might or could not be the case are not basic but grounded in more fundamental features of reality. Steinberg develops this insight into a novel account of the supervenience structure of the modal realm. This study was awardedthe 2012 GAP/ontos award.".

ABSTRACTIn the target article, Stephen Yablo appeals crucially to the notion of surplus content. But when he does so, it is by appeal to the notion of mathematical addition and subtraction. In this commentary, I argue that the analogy with mathematical subtraction is underdeveloped and potentially misleading.

In his recent book 'Pleonastische Propositionen' Matthias Schürmann presents and defends an account of propositions as pleonastic entities. In this paper I challenge one of his main claims, namely that pleonastic propositions are ontologically dependent on thinkers. I argue that Schürmann's dependence claim is in tension with core tenets of a pleonastic account and, hence, unavailable for an elaboration of what it means that pleonastic entities are ontologically lightweight.
