Grosseteste holds that true propositions about the present may well be contingent on this conception of contingency, since they can become false; he gives “Socrates is pale” as an example (Lewis 2017, 41).  But he holds that all true propositions about the future are necessary.  It might be thought that this is incorrect, since it is not hard to think of cases in which a true proposition about the future becomes false after the occurrence of an event it predicts. But closer inspection reveals that Grosseteste thinks that true propositions about the future are necessary because they cannot become false prior to the obtaining of the state of affairs they are about; he has a limited unchangeability of truth in mind.
