Moritz Schulz explores counterfactual thought and language: what would have happened if things had gone a different way. Counterfactual questions may concern large scale derivations (what would have happened if Nixon had launched a nuclear attack) or small scale evaluations of minor derivations (what would have happened if I had decided to join a different profession). A common impression, which receives a thorough defence in the book, is that oftentimes we find it impossible to know what would have happened. However, this does not mean that we are completely at a loss: we are typically capable of evaluating counterfactual questions probabilistically: we can say what would have been likely or unlikely to happen. Schulz describes these probabilistic ways of evaluating counterfactual questions and turns the data into a novel account of the workings of counterfactual thought.

This volume contains fifteen essays in honour of Wolfgang K nne. The essays deal with issues from the philosophy of language and logic, broadly conceived. They cover topics ranging from truth, reference, and the ontology of abstract objects, to action, intentionality, and speech acts. By taking into account the works of early analytic philosophers-including Bolzano, Frege, Peirce, Husserl, and Wittgenstein-they foster our understanding of the history of the ideas discussed, while at the same time contributing to the systematic debate. The collection also includes an up-to-date bibliography of K nne's published work.
