Chisholm recognizes that we sometimes use intentional sentences to describe nonpsychological facts. For example, consider the sentence ‘This weapon, suitably placed, is capable of making it be the case that Boston is destroyed.’ Neither that sentence nor its negation entails either that Boston is destroyed or that Boston is not destroyed. So it carries the second mark of intentionality. But it seems not to be psychological. Chisholm claims that we can rephrase the sentence nonintentionally: ‘If this weapon were suitably placed, then Boston would be destroyed.’ This is a compound sentence. Reflection will reveal that neither component carries any of the marks of intentionality. (The critic may wonder whether this reply is entirely satisfactory, since it may seem that the paraphrase does not mean precisely what the original meant.)
