 Belnap et al. have argued that it is implausible to assume that there could be some property which could “justify treating some maximal chains as real possibilities and others as not” (Belnap et al. 2001, p. 205). On the other hand, Nishimura’s example is in fact a rather remarkable argument suggesting that not all maximal chains have to be accepted as chronicles in the semantics for future contingents. The example also speaks in favor of the view that the Leibnizian theory is more plausible than Prior’s Ockhamistic theory, see (Øhrstrøm and Hasle 1995, p. 268).
