Chisholm’s Paradox, presented in Chisholm (1967), begins innocuously enough. Suppose that individuals are identical across possible worlds such that de re modal claims like “Fred could have been taller” are true only in case there is some possible world where the very same individual, in this case, Fred, is taller than he is in the actual world. Now, consider that two actual individuals, Adam and Noah, could have had slightly different qualitative properties. For example, Adam, instead of dying at age 930, could have died at age 931. Similarly, Noah, instead of dying at age 950, could have died at age 949. If Adam and Noah can tolerate these incremental “changes” to each of their qualitative profiles, it seems that had they been a different way than they actually are, they could have tolerated even further incremental changes.
