The Utility of Time-Symmetric Quantum Counterfactuals: A Response to Kastner
U. Mohrhoff
TL;DR
This paper defends the use of time-symmetric quantum counterfactuals against recent objections, arguing that the criticisms are unfounded and do not undermine their validity or usefulness.
Contribution
It provides a rebuttal to Kastner's objections, clarifying the validity and significance of time-symmetric quantum counterfactuals in quantum theory.
Findings
Objections to time-symmetric quantum counterfactuals are unfounded.
The Aharonov-Bergmann-Lebowitz rule remains valid for counterfactual reasoning.
Time-symmetric quantum counterfactuals are not vacuous or invalid.
Abstract
Kastner's (Philosophy of Science 70, 2003, pp. 145--163) recent objections to the counterfactual usage of the time-symmetric Aharonov-Bergmann-Lebowitz rule by the author, especially her claims that the resulting time-symmetric quantum counterfactuals are vacuous or invalid, are examined and shown to be unfounded or beside the point.
