Free Will and Intensional Operators

Arguments challenging the existence of free will frequently share a common structure, relying on variants of a principle we call C losure , according to which having no choice about a truth is preserved under entailment. We show that, under plausible assumptions, C losure is valid if and only if the ‘no choice’ operator is intensional. By framing the debate in terms of the intensionality of this operator, this paper illuminates previously underappreciated constraints on defenses of C losure -based arguments against the existence of free will.
