The technical term direction-of-fit is used to describe the distinctions that are offered by two related sets of opposing terms:

  • The more general set of mind-to-world (i.e., mind-to-fit-world, not from-mind-to-world) vs. world-to-mind (i.e., world-to-fit-mind) used by philosophers of mind, and
  • The narrower, more specific set, word-to-world (i.e., word-to-fit-world) vs. world-to-word (i.e., world-to-fit-word) used by advocates of speech act theory.

In philosophy of mind, a belief is true when it has a mind-to-world direction of fit, and false when there is no such fit. A belief that p depicts the world as being in a state of affairs such that p is true. Beliefs, some philosophers have argued, aim at the truth and so aim to fit the world. A belief is satisfied when it fits the world.

A desire, on the other hand, normally expresses a yet to be realized state of affairs and so has a world-to-mind direction of fit. A desire that p, unlike a belief, doesn't depict the world as being in the state that rather it expresses a desire that the world be such that p is true. Desire is a state that is satisfied when the world fits it.

A way to account for the difference is that a (rational) person that holds the belief that p when confronted with evidence that not-p, will revise his belief, whereas a person that desires that p can retain his desire that p in the face of evidence that not-p.

To a philosopher of language a word-to-world fit occurs when, say, a sports journalist correctly names Jones as a goal scorer; whilst if the journalist mistakenly names Smith as the goal scorer, the printed account does not display a word-to-world fit, and must be altered such that it matches the real world. Conversely, a world-to-word fit occurs when a fan of Smith's team opines that they deserved to win the match, even though they lost. In this case, the world would have to change to make the sports fan's wish become true.

However, in the case of, say, a judge delivering a death sentence to a criminal declared guilty by a jury, the utterances of the judge alter the world, through the actual fact of that utterance; and, in this case, the judge is generating a world-to-word-to-world fit (see below). So, if the judge's opinion is upheld, the world must be altered to match the content of the judge's utterance (i.e., the criminal must be executed).

In speech act theoryEdit

Perhaps the first to speak of a "direction of fit" was the philosopher J. L. Austin. Austin did not use the distinction between differernt directions of fit to contrast commands or expressions of intention to assertions, or desires to beliefs. He rather distinguishes different ways of asserting that an item is of a certain type.

In an extensive discussion[1] of the issues involved with the differences between, say, (a) wrongly calling a triangle a square (something which, he said, was committing an act of violence to the language) and (b) wrongly describing a triangular object as being a square (something which, he said, was committing an act of violence to the facts), Austin distinguished between what he termed:

  • "the onus of match": in the case of one wanting to match X and Y, the distinction between the matching of X to Y and the matching of Y to X; and
  • "the direction of fit": in the case of naming something, the difference between the fitting of a name to an item, and the fitting of an item to a name.

The concept of direction of fit can also apply to speech acts: e.g., declarations have word-to-world direction of fit, whilst commands and promises have a world-to-word direction of fit.

John Searle and Daniel Vanderveken[2]assert that there are only four possible "directions of fit" in language:

1. The word-to-world direction of fit.
In achieving success of fit the propositional content of the utterance fits an independently existing state of affairs in the world. Eg: "We are married".
2. The world-to-word direction of fit.
To achieve success of fit the world must change to match the propositional content of the utterance. Eg: "Will you marry me?", "I want to marry him", "You'd just better marry her, buddy!", etc.
3. The double direction of fit.
To achieve success of fit the world is thereby altered to fit the propositional content by representing the world as being so altered, unlike sense 2. Eg: "I declare you man and wife". The 'doubled' direction is therefore always world-to-word-to-world. For obvious reasons, Searle calls sentences of this type 'declarations'.
4. The null or empty direction of fit.
There is no direct question of achieving success of fit between the propositional content and the world, because success of fit is presupposed by the utterance. Eg: "I'm glad I married you" presupposes that the speaker is married to the listener.

Searle used this notion of "direction of fit" to create a taxonomy of illocutionary acts.[3]

Although Elizabeth Anscombe never employed the term "the direction of fit", Searle has strongly argued[4] that the following passage from her work Intention was, by far, "the best illustration" of the distinction between the tasks of "[getting] the words (more strictly their propositional content) to match the world… [and that of getting] the world to match the words":

§32. Let us consider a man going round a town with a shopping list in his hand. Now it is clear that the relation of this list to the things he actually buys is one and the same whether his wife gave him the list or it is his own list; and that there is a different relation where a list is made by a detective following him about. If he made the list itself, it was an expression of intention; if his wife gave it him, it has the role of an order. What then is the identical relation to what happens, in the order and the intention, which is not shared by the record? It is precisely this: if the list and the things that the man actually buys do not agree, and if this and this alone constitutes a mistake, then the mistake is not in the list but in the man's performance (if his wife were to say: “Look, it says butter and you have bought margarine”, he would hardly reply: “What a mistake! we must put that right” and alter the word on the list to “margarine”); whereas if the detective's record and what the man actually buys do not agree, then the mistake is in the record.[5]

In philosophy of mindEdit

According to Velleman, when used in the domain of the philosophy of mind, the concept direction of fit represents the distinguishing feature between two types of intentional mental states:

Facta (singular factum, states that currently exist) are states with a mind-to-world direction of fit.
Examples include beliefs, perceptions, hypotheses, and fantasies. In the event of a mismatch between the mental state and the world, the mental state is in some sense false or wrong and should perhaps be changed.
Facienda (singular faciendum, states that are yet to exist) are states with a world-to-mind direction of fit.
Examples include intentions and desires. If there is a mismatch between the mental state and the world, the world is in some sense wrong and should perhaps be changed.

In some forms of mind-body dualism, a matching factum and faciendum must be present in a person's mind in order for him to act intentionally. If a person has the belief that action (A) will lead to state (S), and has the desire that state (S) obtain, then he will perform action (A). The action is directly caused by simultaneous presence of the two mental states; no further explanation is needed.

According to Velleman:

The term "direction of fit" refers to the two ways in which attitudes can relate propositions to the world.
In cognitive attitudes [such as belief], a proposition is grasped as patterned after the world; whereas in conative attitudes [such as desire], the proposition is grasped as a pattern for the world to follow.
The propositional object of desire is regarded not as fact -- not, that is, as factum, having been brought about -- but rather as faciendum, to be brought about: it's regarded not as true but as to be made true.[6]
