Full Idea
There are events of which it is neither definitely true nor definitely false that those events are lives. I do not see how we can deny this.
Gist of Idea
Some events are only borderline cases of lives

A Reaction
Very frustrating, since this is my main objection to Van Inwagen's distinction between unified lives and mere collections of simples. Some boundaries are real enough, despite their vagueness, and others indicate that there is no real distinction.
