Fatalism is a family of related philosophical doctrines that stress the subjugation of all events or actions to fate or destiny, and is commonly associated with the consequent attitude of resignation in the face of future events which are thought to be inevitable.
The term "fatalism" can refer to any of the following ideas:
While the terms are sometimes used interchangeably, fatalism, determinism, and predeterminism are distinct, as each emphasizes a different aspect of the futility of human will or the foreordination of destiny. However, all these doctrines share common ground.
Determinists generally agree that human actions affect the future but that human action is itself determined by a causal chain of prior events. Their view does not accentuate a "submission" to fate or destiny, whereas fatalists stress an acceptance of future events as inevitable. Determinists believe the future is fixed specifically due to causality; fatalists and predeterminists believe that some or all aspects of the future are inescapable but, for fatalists, not necessarily due to causality.
Fatalism is a looser term than determinism. The presence of historical "indeterminisms" or chances, i.e. events that could not be predicted by sole knowledge of other events, is an idea still compatible with fatalism. Necessity (such as a law of nature) will happen just as inevitably as a chance--both can be imagined as sovereign. This idea has roots in Aristotle's work, "De interpretatione".
Theological fatalism is the thesis that infallible foreknowledge of a human act makes the act necessary and hence unfree. If there is a being who knows the entire future infallibly, then no human act is free. The philosopher Al Farabi makes the case that if God does in fact know all human actions and choices, then Aristotle's original solution to this dilemma stands.
One famous ancient argument regarding fatalism was the so-called Idle Argument. It argues that if something is fated, then it would be pointless or futile to make any effort to bring it about. The Idle Argument was described by Origen and Cicero and it went like this:
The Idle Argument was anticipated by Aristotle in his De Interpretatione chapter 9. The Stoics considered it to be a sophism and the Stoic Chrysippus attempted to refute it by pointing out that consulting the doctor would be as much fated as recovering. He seems to have introduced the idea that in cases like that at issue two events can be co-fated, so that one cannot occur without the other.
The main argument for logical fatalism goes back to antiquity. This is an argument 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 arguments have been objected to and elaborated on with some effect.
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.
One criticism comes from the novelist David Foster Wallace, who in a 1985 paper "Richard Taylor's Fatalism and the Semantics of Physical Modality" suggests that Taylor reached his conclusion of fatalism only because his argument involved two different and inconsistent notions of impossibility. Wallace did not reject fatalism per se, as he wrote in his closing passage, "if Taylor and the fatalists want to force upon us a metaphysical conclusion, they must do metaphysics, not semantics. And this seems entirely appropriate." Willem deVries and Jay Garfield, both of whom were advisers on Wallace's thesis, expressed regret that Wallace never published his argument. In 2010, the thesis was, however, published posthumously as Time, Fate, and Language: An Essay on Free Will.
