The Arguments on Fatalism: Riddles Ch. 2

What fatalism is: ________________________________________________________

Below are valid arguments: the reasoning is fine.

Are they sound? What can be said for and against the premises? Are any of the premises unreasonable to accept because there are good reasons to think they are false?

Arguments from Predications and (Past) Propositions: The Sea Battle

A1. Either the prediction that the battle will happen is true, or the prediction that the battle will not happen is true. (Or, either of the propositions is true).

Why? LEM (p. 27). Objections re. settled facts and future truth makers.

Doubts from vagueness!

A2. If any statement is true, then it has to be true.


It has to be true that: if any statement is true, then it’s true.

If any statement is true, then it has to be true.

C1. Whatever predication (or proposition) is true has to be true.

C2. Whether the battle will happen or not is necessary.

Same argument can be given about every event.

Past Predications

A1. For any way that things will be in the future, there existed in the past a true proposition to the effect that things would be that way. (p. 32).

A2. Every aspect of the past is accidentally necessary, i.e., ________________.

C1. The truth in the past of each true predictive proposition is accidentally necessary.

C2. Therefore, the future in every detail is accidentally necessary.

Necessary Conditions (p. 35)

A1. If something has/is an open alternative/possibility, then all that is needed for the alternative to exist is present. (Something is fixed/unalterable/not an open alternative/possibility if any necessary condition for not having the thing is absent).

A2. Any condition is a necessary condition for itself.

C. Therefore, all actual entities, events and circumstances – past, present and future – are fixed and unalterable down to the last detail.

God Knows (p. 39)

A1. If God knows everything, then God knows in advance (or in eternity) all truths about the whole future.

A2. If God knows any given truth about the future, then any potential for that truth to be untrue would be a potential for God to be mistaken about it.

A3. It’s impossible for God to be mistaken about anything.

C. If God knows everything, then the whole future is fixed and unalterable.
