In the course of a controversy with donald davidson, Professor chisholm, In several papers, Presents and defends an argument (in support of his views on events) whose conclusion is that nixon's becoming president (n) and johnson's becoming president (j) are distinct events, Despite nixon's being johnson's successor. The argument hangs on the claim that n, But not j, Would have failed to have occurred, If humphrey had won the election. I argue, However, That chisholm's argument seems to work only if (...) 'j' is construed as a rigid designator, And that such a construal begs the question at issue. Moreover, If 'j' is taken as a non-Rigid designator, Then his argument is irrelevant. Thus, Chisholm's "counterfactual argument," I conclude, Cannot be used in favor of chisholm's view of events as a species of states of affairs. (shrink)
