We need to understand the impossible. Francesco Berto and Mark Jago start by considering what the concepts of meaning, information, knowledge, belief, fiction, conditionality, and counterfactual supposition have in common. They are all concepts which divide the world up more finely than logic does. Logically equivalent sentences may carry different meanings and information and may differ in how they're believed. Fictions can be inconsistent yet meaningful. We can suppose impossible things without collapsing into total incoherence. Yet for the leading philosophical (...) theories of meaning, these phenomena are an unfathomable mystery. To understand these concepts, we need a metaphysical, logical, and conceptual grasp of situations that could not possibly exist: Impossible Worlds. This book discusses the metaphysics of impossible worlds and applies the concept to a range of central topics and open issues in logic, semantics, and philosophy. It considers problems in the logic of knowledge, the meaning of alternative logics, models of imagination and mental simulation, the theory of information, truth in fiction, the meaning of conditional statements, and reasoning about the impossible. In all these cases, impossible worlds have an essential role to play. (shrink)

Brentanos 1904 vollendete Theorie, nur Reales sei vorstellbar und könne existieren, führte auch unter seinen Schülern zu Kontroversen. Dieser Band enthält eine umfangreiche Studie, die Einleitung der Herausgeber zu diesem Problemkreis, Auszüge aus dem Briefwechsel mit A. Marty und O. Kraus sowie die einschlägigen Abhandlungen Brentanos.

Public reason as a political ideal aims to reconcile reasonable disagreement; however, is public reason itself the object of reasonable disagreement? Jonathan Quong, David Estlund, Andrew Lister, and some other philosophers maintain that public reason is beyond reasonable disagreement. I argue this view is untenable. In addition, I consider briefly whether or not two main versions of the public reason principle, namely, the consensus version and the convergence version, need to satisfy their own requirements. My discussion has several important implications (...) for the debate on public reason. (shrink)

Democratic decision-making is often defended on grounds of the ‘wisdom of crowds’: decisions are more likely to be correct if they are based on many independent opinions, so a typical argument in social epistemology. But what does it mean to have independent opinions? Opinions can be probabilistically dependent (threatening the ‘wisdom of crowds’) even if individuals form their opinion in causal isolation from each other. We distinguish four probabilistic notions of opinion independence. Which of them holds depends on how individuals (...) are causally affected by environmental factors such as commonly perceived evidence. In a general theorem, we identify causal conditions guaranteeing each kind of opinion independence. These results have implications for whether and how ‘wisdom of crowds’ arguments are possible, and how truth-conducive institutions can be designed. (shrink)
