Logical Fatalism and The Argument From Bivalence
Another famous argument for fatalism that goes back to antiquity is one that depends not on causation or physical circumstances but rather is based on presumed logical truths. There are numerous versions of this argument, including those by Aristotle and Richard Taylor. These have been objected to and elaborated on but do not enjoy mainstream support.
The key idea of logical fatalism is that there is a body of true propositions (statements) about what is going to happen, and these are true regardless of when they are made. So, for example, if it is true today that tomorrow there will be a sea battle, then there cannot fail to be a sea battle tomorrow, since otherwise it would not be true today that such a battle will take place tomorrow.
The argument relies heavily on the principle of bivalence: the idea that any proposition is either true or false. As a result of this principle, if it is not false that there will be a sea battle, then it is true; there is no in-between. However, rejecting the principle of bivalence—perhaps by saying that the truth of a proposition regarding the future is indeterminate—is a controversial view since the principle is an accepted part of classical logic.
Another criticism of logical fatalism is that it assumes a timeless set of all propositions which exist without being proposed by anyone in particular. Constructivists (a school of thought in logic and mathematics) argue that this is not the case and that propositions only exist when they are constructed or expressed.
