Counting the Minds of Split-Brain Patients
Gert-Jan C. Lokhorst, Logic & Analysis, September–December 1996, 39, 315–324.
Abstract: Using Fagin’s and Halpern’s local reasoning models and an epistemic variant of Jennings’s and Schotch’s semantics of weakly aggregative modal logic, we argue that the hypothesis that split-brain patients have two coherent minds is preferable to the hypothesis that they have one incoherent mind.
