Full Idea
Mark Hinchliff distinguishes between 'Serious' Presentism (objects only have relations and properties when they exist) and 'Unrestricted' Presentism (objects can have relations and properties even when they don't exist).
Gist of Idea
Serious Presentism says things must exist to have relations and properties; Unrestricted version denies this

A Reaction
[Hinchliff 1996:124-6] Markosian votes for the Serious version, as being the only true Presentism. I think he is muddling language and reality, predicates and properties.
