[filed under theme 3. Truth / B. Truthmakers / 7. Making Modal Truths ]

Full Idea

It seems reasonable to say that a truthmaker for a contingent truth is also a truthmaker for the truth that the contradictory of that truth is possible.

Gist of Idea

One truthmaker will do for a contingent truth and for its contradictory

A Reaction

The truthmaker will have to be not only some fact, but also the additional fact that it is contingent, in order to generate the possibility of the contradictory.
