Abstract

In an appendix entitled ‘How Indeterminateness Becomes Determinateness’, Nuel Belnap calls attention to one feature of the version of indeterminism presented in his paper ‘Branching Space-Time.’ According to this theory, “a causal origin has always ‘a last point of indeterminateness’ … and never ‘a first point of determinateness’.” Belnap remarks: “I find the matter puzzling since it's neither clear to me how an alternate theory would work nor clear what difference it makes.”
