Informative Counterfactuals

چکیده
A single counterfactual conditional can have a multitude of interpretations that differ, intuitively, in the connection between antecedent and consequent. Using structural equation models (SEMs) to represent event dependencies, we illustrate various types of explanation compatible with a given counterfactual. We then formalize in the SEM framework the notion of an acceptable explanation, identifying the class of event dependencies compatible with a given counterfactual. Finally, by incorporating SEMs into possible worlds, we provide an update semantics with the enriched structure necessary for the evaluation of counterfactual conditionals.

Free Choice for Simplification
The fact that counterfactuals in general license simplification of disjunctive antecedents is a familiar problem for the traditional Lewis-Stalnaker variably strict analysis of counterfactuals. This paper demonstrates that the data are well explained by a dynamic strict analysis of counterfactuals that uses ideas from the inquisitive semantic tradition to provide a satisfying semantic explanati...
متن کاملWhich Counterfactuals Matter? A Response to Beck
In our article (Weisberg & Gopnik, 2013), we construct a unifying theory of imaginative processes, in which counterfactuals and pretend games share an underlying cognitive capacity. This theory allows us to explain why children pretend, why they create fantastical pretend worlds, and how pretend play and counterfactual reasoning can help children to learn about the causal structure of reality. ...
متن کاملTime-Symmetrized Counterfactuals in Quantum Theory
Counterfactuals in quantum theory are briefly reviewed and it is argued that they are very different from counterfactuals considered in the general philosophical literature. The issue of time symmetry of quantum counterfactuals is considered and a novel time-symmetric definition of quantum counterfactuals is proposed. This definition is applied for analyzing several controversies related to qua...
متن کاملWhat-If at Waterloo. Carl von Clausewitz’s use of historical counterfactuals in his history of the Campaign of 1815
In this article, I analyze the use of historical counterfactuals in the Campaign of 1815 by Carl von Clausewitz (1780–1831). Such is the importance of counterfactuals in this work that its gist can be given in a series of 25 counterfactuals. I claim that a central role is played by evaluative counterfactuals. This specific form of counterfactuals is part of a didactic method that allows Clausew...
متن کاملThe day after an electoral defeat: counterfactuals and collective action.
An intriguing question for scholars of collective action is how participants of unsuccessful actions become re-engaged in future collective activities. At an individual level, previous research has shown that after negative outcomes counterfactual thoughts ('if only … ') may serve to prepare for future action. In the current research, we investigated whether counterfactuals may also prepare for...
