 Such a view immediately raises a worry about false propositions (discussed below in connection with Russell’s POM account of propositions). For one might argue as follows. Suppose Ed doesn’t run. Then Ed doesn’t plug/saturate the one argument place in the property of running (i.e. doesn’t possess this property). But Ed possessing the running property just is the proposition that Ed runs. Thus there is no proposition that Ed runs. Similar reasoning shows that any other false proposition fails to exist. So there are no false propositions.
