This apparently how philosophers prove fatalism, ie that whatever will happen in the future is already unavoidable:

(1) There exist now propositions about everything that might happen in the future.[1]
(2) Every proposition is either true or else false.
(3) If (1) and (2), then there exists now a set of true propositions that, taken together, correctly predict everything that will happen in the future.
(4) If there exists now a set of true propositions that, taken together, correctly predict everything that will happen in the future, then whatever will happen in the future is already unavoidable.
∴ (5) Whatever will happen in the future is already unavoidable.

Are these people for real? I mean, how can you not see a glaring hole in this argument?
