 It turns out that MacFarlane’s theory implies an acceptance of the principle of future excluded middle, (P5), and a rejection of the principle of the necessity of the past, (P3). An advocate of the theory (i.e., a relativist) will clearly also agree with supervaluationism in allowing for truth-value gaps. However, in addition a relativist will accept the view that future contingents can be true as assessed from a future context. For criticism of MacFarlane’s position see Heck 2006.
