Ideas of Peter Forrest, by Text

[American, fl. 2009, At the University of New England.]

1986 Ways Worlds Could Be
p.78 Structural universals might serve as possible worlds
     Full Idea: Forrest proposed that structural universals should serve as ersatz possible worlds.
     From: report of Peter Forrest (Ways Worlds Could Be [1986]) by David Lewis - Against Structural Universals 'Intro'
     A reaction: I prefer powers to property universals. Perhaps a possible world is a maximal set of co-existing dispositions?
2006 General Facts,Phys Necessity, and Metaph of Time
1 p.137 The truth-maker principle is that every truth has a sufficient truth-maker
     Full Idea: Item x is said to be a sufficient truth-maker for truth-bearer p just in case necessarily if x exists then p is true. ...Every truth has a sufficient truth-maker. Hence, I take it, the sum of all sufficient truth-makers is a universal truth-maker.
     From: Peter Forrest (General Facts,Phys Necessity, and Metaph of Time [2006], 1)
     A reaction: Note that it is not 'necessary', because something else might make p true instead.
