signs and the kinds of things they
mean (intend, express or signify)'. One term in the relation of meaning necessarily causes something else to come to the mind in consequence. In other words: 'a sign is defined as an
entityAn entity is something that has a distinct, separate existence, though it need not be a material existence. In particular, abstractions and legal fictions are usually regarded as entities. In general, there is also no presumption that an entity is animate...
that indicates another entity to some agent for some purpose'.
The types of meanings vary according to the types of the thing that is being represented. Namely:
- There are the things in the world, which might have meaning;
- There are things in the world that are also signs of other things in the world, and so, are always meaningful (i.e., natural signs of the physical world and ideas within the mind);
- There are things that are always necessarily meaningful, such as words, and other nonverbal symbols.
All subsequent inquiries emphasize some particular perspectives within the general AAA framework.
The major contemporary positions of meaning come under the following partial definitions of meaning:

s, or to mental activity in general. Those who seek an explanation for meaning in the former sort of account endorse a stronger sort of idea theory of mind than the latter.
Each idea is understood to be necessarily
about something external and/or internal, real or imaginary. For example, in contrast to the abstract meaning of the
universalIn metaphysics, a universal is what particular things have in common, namely characteristics or qualities. In other words, universals are repeatable or recurrent entities that can be instantiated or exemplified by many particular things. For example, suppose there are two chairs in a room, each of...
"dog", the referent "this dog" may mean a particular real life chihuahua. In both cases, the word is about something, but in the former it is about the class of dogs as generally understood, while in the latter it is about a very real and particular dog in the real world.

held however that ideas alone are unable to account for the different variations within a general meaning. For example, any hypothetical image of the meaning of "dog" has to include such varied images as a chihuahua, a pug, and a Black Lab; and this seems impossible to imagine, all of those particular breeds looking very different from one another. Another way to see this point is to question why it is that, if we have an image of a specific type of dog (say of a chihuahua), it should be entitled to represent the entire concept.
Another criticism is that some meaningful words, known as non-lexical items, don't have any meaningfully associated image. For example, the word "the" has a meaning, but one would be hard-pressed to find a mental representation that fits it. Still another objection lies in the observation that certain linguistic items name something in the real world, and are meaningful, yet which we have no mental representations to deal with. For instance, it is not known what Bismarck's mother looked like, yet the phrase
"Bismarck's mother" still has meaning.
Another problem is that of composition - that it is difficult to explain how words and phrases combine into sentences if only ideas were involved in meaning.

advanced the the theory of prototypes, which suggests that many lexical categories, at least on the face of things, have "radial structures". That is to say, there are some ideal member(s) in the category that seem to represent the category better than other members. For example, the category of "birds" may feature the
robin as the prototype, or the ideal kind of bird. With experience, subjects might come to evaluate membership in the category of "bird" by comparing candidate members to the prototype and evaluating for similarities. So, for example, a penguin or an ostrich would sit at the fringe of the meaning of "bird", because a penguin is unlike a robin.
Intimately related to these researches is the notion of a
psychologically basic level, which is both the first level named and understood by children, and "the highest level at which a single mental image can reflect the entire category". (Lakoff 1987:46) The "basic level" of cognition is understood by Lakoff as crucially drawing upon "image-schemas" along with various other cognitive processes.

On Sense and Reference),

As a philosopher, he is generally considered to be the father of analytic philosophy, for his...
argued that proper names present at least two problems in explaining meaning.
- Suppose the meaning of a name is the thing it refers to. Sam, then, means a person in the world who is named Sam. But if the object referred to by the name did not exist -- i.e., Pegasus -- then, according to that theory, it would be meaningless.
- Suppose two different names refer to the same object. Hesperus and Phosphorus were the names given to what were considered distinct celestial bodies. It was later shown that they were the same thing (the planet Venus). If the words meant the same thing, then substituting one for the other in a sentence would not result in a sentence that differs in meaning from the original. But in that case, "Hesperus is Phosphorus" would mean the same thing as "Hesperus is Hesperus". This is clearly absurd, since we learn something new and unobvious by the former statement, but not by the latter.
Frege can be interpreted as arguing that it was therefore a mistake to think that the meaning of a name is the thing it refers to. Instead, the meaning must be something else—the "sense" of the word. Two names for the same person, then, can have different senses (or meanings): one referent might be picked out by more than one sense. This sort of theory is called a
mediated reference theoryThe mediated reference theory is a semantic theory that posits that words refer to something in the external world, but insists that there is more to the meaning of a name than simply the object to which it refers. It thus stands opposed to the theory of direct reference. Its most famous advocate...

Frege argued that, ultimately, the same bifurcation of meaning must apply to most or all linguistic categories, such as to quantificational expressions like "All boats float". Ironically enough, it is now accepted by many philosophers as applying to all expressions
but proper names.

, which attempted to produce a formal language with which the truth of all mathematical statements could be demonstrated from first principles.
Russell differed from Frege greatly on many points, however. He rejected (or perhaps misunderstood) Frege's sense-reference distinction. He also disagreed that language was of fundamental significance to philosophy, and saw the project of developing formal logic as a way of eliminating all of the confusions caused by ordinary language, and hence at creating a perfectly transparent medium in which to conduct traditional philosophical argument. He hoped, ultimately, to extend the proofs of the
Principia to all possible true statements, a scheme he called

most of which was derived (albeit very distantly) from the work of Hegel. In response Moore developed an approach ("Common Sense Philosophy") which sought to examine philosophical difficulties by a close analysis of the language used in order to determine its meaning. In this way Moore sought to expunge philosophical absurdities such as "time is unreal". Moore's work would have significant, if oblique, influence (largely mediated by Wittgenstein) on

Other truth theories
The Vienna Circle, a famous group of logical positivists from the early 20th century (closely allied with Russell and Frege), adopted the verificationist theory of meaning. The verificationist theory of meaning (in at least one of its forms) states that to say that an expression is meaningful is to say that there are some conditions of experience that could exist to show that the expression is true. As noted, Frege and Russell were two proponents of this way of thinking.

Donald DavidsonDonald Herbert Davidson was an American philosopher who served as Slusser Professor of Philosophy at the University of California, Berkeley from 1981 to 2003 after having also held substantive teaching appointments at Stanford University, Rockefeller University, Princeton University, and the...
in his introduction to the collection of essays
Truth and Meaning in 1967. There he argued for the following two theses:
- Any learnable language must be statable in a finite form, even if it is capable of a theoretically infinite number of expressions--as we may assume that natural human languages are, at least in principle. If it could not be stated in a finite way then it could not be learned through a finite, empirical method such as the way humans learn their languages. It follows that it must be possible to give a theoretical semantics for any natural language which could give the meanings of an infinite number of sentences on the basis of a finite system of axioms.
- Giving the meaning of a sentence, he further argued, was equivalent to stating its truth conditions. He proposed that it must be possible to account for language as a set of distinct grammatical features together with a lexicon, and for each of them explain its workings in such a way as to generate trivial (obviously correct) statements of the truth conditions of all the (infinitely many) sentences built up from these.
The result is a theory of meaning that rather resembles, by no accident, Tarski's account.
Davidson's account, though brief, constitutes the first systematic presentation of

was that the reference of a proper name is
necessarily linked to its referent, but that the sense is not. So for instance "Hesperus" necessarily refers to Hesperus, even in those imaginary cases and worlds in which perhaps Hesperus is not the evening star. That is, Hesperus is necessarily Hesperus, but only contingently the morning star.
This results in the curious situation that part of the meaning of a name - that it refers to some particular thing - is a necessary fact about that name, but another part - that it is used in some particular way or situation - is not.

. The speaker's meaning is what the speaker intends to refer to by saying something; the semantic meaning is what the words uttered by the speaker mean according to the language.
In some cases, people do not say what they mean; in other cases, they say something that is in error. In both these cases, the speaker's meaning and the semantic meaning seem to be different. Sometimes words do not actually express what the speaker wants them to express; so words will mean one thing, and what people intend to convey by them might mean another. The meaning of the expression, in such cases, is ambiguous.
Critiques of truth-theories of meaning
W.V. Quine attacked both verificationism and the very notion of meaning in his famous essay, "
Two Dogmas of EmpiricismW. V. O. Quine's paper "Two Dogmas of Empiricism", published in 1951, is one of the most celebrated papers of twentieth century philosophy in the analytic tradition. According to Harvard professor of philosophy Peter Godfrey-Smith, this "paper [is] sometimes regarded as the most important in all...
". In it, he suggested that meaning was nothing more than a vague and dispensable notion. Instead, he asserted, what was more interesting to study was the synonymy between signs. He also pointed out that verificationism was tied to the distinction between analytic and synthetic statements, and asserted that such a divide was defended ambiguously. He also suggested that the unit of analysis for any potential investigation into the world (and, perhaps, meaning) would be the entire body of statements taken as a collective, not just individual statements on their own.
Other criticisms can be raised on the basis of the limitations that truth-conditional theorists themselves admit to. Tarski, for instance, recognized that truth-conditional theories of meaning only make sense of statements, but fail to explain the meanings of the lexical parts that make up statements. Rather, the meaning of the parts of statements is presupposed by an understanding of the truth-conditions of a whole statement, and explained in terms of what he called "satisfaction conditions".
Still another objection (noted by Frege and others) was that some kinds of statements don't seem to have any truth-conditions at all. For instance, "Hello!" has no truth-conditions, because it doesn't even attempt to tell the listener anything about the
state of affairsThe state of affairs is that combination of circumstances applying within a society or group at a particular time.

in the world. In other words, different propositions have different grammatical moods.
DeflationistThe deflationary theory of truth is a family of theories which all have in common the claim that assertions that predicate truth of a statement do not attribute a property called truth to such a statement.-Redundancy theory:...
accounts of truth, sometimes called 'irrealist' accounts, are the staunchest source of criticism of truth-conditional theories of meaning. According to them, "truth" is a word with no serious meaning or function in discourse. For instance, for the deflationist, the sentences "It's true that Tiny Tim is trouble" and "Tiny Tim is trouble" are equivalent. In consequence, for the deflationist, any appeal to truth as an account of meaning has little explanatory power.
The sort of truth-theories presented here can also be attacked for their

both in practice and principle. The principle of formalism is challenged by the informalists, who suggest that language is largely a construction of the speaker, and so, not compatible with formalization. The practice of formalism is challenged by those who observe that formal languages (such as present-day quantificational logic) fail to capture the expressive power of natural languages (as is arguably demonstrated in the awkward character of the quantificational explanation of definite description statements, as laid out by Bertrand Russell).
Finally, over the past century, forms of logic have been developed that are not dependent exclusively on the notions of truth and falsity. Some of these types of logic have been called
modal logicA modal logic is any system of formal logic that attempts to deal with modalities. Modals qualify the truth of a judgment.

Peter Strawson
Past philosophers had understood reference to be tied to words themselves. However, Sir Peter Strawson disagreed in his seminal essay, "On Referring", where he argued that there is nothing true about statements on their own; rather, only the uses of statements could be considered to be true or false.
Indeed, one of the hallmarks of the ordinary use perspective is its insistence upon the distinctions between meaning and use.
"Meanings", for ordinary language philosophers, are the
instructions for usage of words - the common and conventional definitions of words.
Usage, on the other hand, is the actual meanings that individual speakers have - the things that an individual speaker in a particular context wants to refer to. The word "dog" is an example of a meaning, but pointing at a nearby dog and shouting "This dog smells foul!" is an example of usage. From this distinction between usage and meaning arose the divide between the fields of

Pragmatics encompasses speech act theory, conversational implicature, talk in interaction and other approaches to language behavior in philosophy, sociology, and linguistics. It studies how the...

It is often used in ordinary language to denote a problem of understanding that comes down to word selection or connotation. This problem of...

Yet another distinction is of some utility in discussing language: "mentioning".
Mention is when an expression refers to itself as a linguistic item, usually surrounded by quotation marks. For instance, in the expression "'Opopanax' is hard to spell", what is referred to is the word itself ("opopanax") and not what it means (an obscure gum resin). Frege had referred to instances of mentioning as "opaque contexts".

sought to improve upon Strawson's distinction. He pointed out that there are two uses of definite descriptions:
attributive and
referential. Attributive uses provide a description of whoever is being referred to, while referential uses point out the actual referent. Attributive uses are like mediated references, while referential uses are more directly referential.
Paul Grice
The philosopher

, working within the ordinary language tradition, understood "meaning" - in his 1957 eponymous article - to have two kinds:
natural and
non-natural.
Natural meaning had to do with cause and effect, for example with the expression "these spots mean measles".
Non-natural meaning, on the other hand, had to do with the intentions of the speaker in communicating something to the listener.
In his essay,
Logic and Conversation, Grice went on to explain and defend an explanation of how conversations work. His guiding maxim was called the
cooperative principle, which claimed that the speaker and the listener will have mutual expectations of the kind of information that will be shared. The principle is broken down into four maxims:
Quality (which demands truthfulness and honesty),
Quantity (demand for just enough information as is required),
Relation (relevance of things brought up), and
Manner (lucidity). This principle, if and when followed, lets the speaker and listener figure out the meaning of certain implications by way of inference.
The works of Grice led to an avalanche of research and interest in the field, both supportive and critical. One spinoff was called
Relevance theoryThere are two ways to conceive of how thoughts can be communicated from one person to another. The first way is through the use of strict coding and decoding, which makes explicit use of symbols, rules, and language...

", Jurgen Habermas began a program that sought to improve upon the work of the ordinary language tradition. In it, he laid out the goal of a valid conversation as a pursuit of mutual understanding.

to provide a kind of inferential role semantics, where:
- The meaning of sentences and grammatical constructs is given by their assertion conditions; and
- Such a semantics is only guaranteed to be coherent if the inferences associated with the parts of language are in logical harmony

A semantics based upon assertion conditions is called a verificationist semantics: cf. the verificationism of the Vienna Circle.
This work is closely related, though not identical, to one-factor theories of conceptual role semantics.
Critiques of use theories of meaning
Cognitive scientist

He is the State of New Jersey Professor of Philosophy at Rutgers University and is also the author of many works in the fields of philosophy of mind and cognitive science, in which he has laid the groundwork for the modularity of...
has noted that use theories (of the Wittgensteinian kind) seem to be committed to the notion that language is a public phenomenon -- that there is no such thing as a "private language". Fodor opposes such claims because he thinks it is necessary to create or describe the
language of thought, which would seemingly require the existence of a "private language".
Some philosophers of language, such as Christopher Gauker, have criticised Gricean theories of communication and meaning for their excessive focus on the efforts of a listener to discover the speaker's intentions. This, Gauker argues, is not required for linguistic communication, and so will not suffice for theory.
