Full Idea
One theory accepts the reality of the present and the past, but holds that the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world.
Gist of Idea
We could say present and past exist, but not future, so that each event adds to the total history
