The relationship between a sign and its meaning is known as the theory of meaning. It is in this essay that we will discuss the problems with truth-conditional theories regarding meaning, Grice's assessment of the meaning of the speaker and his semantic theory of truth. In addition, we will examine the arguments that Tarski's theory of truth.
Arguments against the truth-based theories of significance
Truth-conditional theories of Meaning claim that meaning is a function from the principles of truth. But, this theory restricts interpretation to the linguistic phenomenon. Davidson's argument essentially argues that truth-values are not always accurate. So, we need to be able to distinguish between truth-values and a flat statement.
Epistemic Determination Argument Epistemic Determination Argument is a method to establish truth-conditional theories for meaning. It relies on two fundamental foundational assumptions: omniscience over nonlinguistic facts as well as knowledge of the truth-condition. However, Daniel Cohnitz has argued against these premises. This argument therefore is not valid.
Another major concern associated with these theories is the lack of a sense of meaning. But, this issue is tackled by a mentalist study. The meaning is considered in the terms of mental representation rather than the intended meaning. For example one person could use different meanings of the term when the same person uses the exact word in both contexts, but the meanings behind those words may be identical even if the person is using the same phrase in two different contexts.
While the major theories of meaning attempt to explain interpretation in mind-based content non-mentalist theories are occasionally pursued. This could be because of the skepticism towards mentalist theories. It is also possible that they are pursued with the view that mental representation should be assessed in terms of linguistic representation.
Another important advocate for this idea A further defender Robert Brandom. This philosopher believes that value of a sentence in its social context in addition to the fact that speech events which involve sentences are appropriate in their context in the context in which they are utilized. He has therefore developed an argumentation theory of pragmatics that can explain sentence meanings by using rules of engagement and normative status.
Probleme with Grice's approach to speaker-meaning
Grice's analysis on speaker-meaning places an emphasis on the speaker's intention , and its connection to the significance of the sentence. Grice argues that intention is an abstract mental state which must be considered in order to determine the meaning of an expression. But, this method of analysis is in violation of the concept of speaker centrism when it examines U-meaning without considering M-intentions. In addition, Grice fails to account for the notion that M-intentions cannot be limited to one or two.
Moreover, Grice's analysis fails to account for some critical instances of intuitive communication. For example, in the photograph example from earlier, the person speaking isn't able to clearly state whether it was Bob either his wife. This is a problem since Andy's photograph does not show the fact that Bob or wife is unfaithful or faithful.
While Grice believes the speaker's meaning is more fundamental than sentence-meaning, there's still room for debate. In actual fact, this distinction is crucial to the naturalistic integrity of nonnatural meaning. Indeed, Grice's purpose is to offer naturalistic explanations for the non-natural meaning.
In order to comprehend a communicative action one must comprehend the speaker's intention, and that intention is a complex embedding of intentions and beliefs. But, we seldom draw complex inferences about mental states in the course of everyday communication. Therefore, Grice's interpretation of meaning of the speaker is not compatible to the actual psychological processes that are involved in language comprehension.
Although Grice's explanation of speaker-meaning is a plausible explanation for the process it is still far from being complete. Others, such as Bennett, Loar, and Schiffer, have created more elaborate explanations. These explanations, however, tend to diminish the plausibility for the Gricean theory, as they regard communication as an act that can be rationalized. In essence, the audience is able to believe what a speaker means as they comprehend the speaker's intention.
Moreover, it does not provide a comprehensive account of all types of speech act. Grice's analysis fails to take into account the fact that speech acts are often used to clarify the meaning of sentences. This means that the value of a phrase is reduced to the speaker's interpretation.
Issues with Tarski's semantic theory of truth
Although Tarski said that sentences are truth bearers However, this doesn't mean any sentence is always accurate. Instead, he aimed to define what constitutes "true" in a specific context. His theory has since become an integral component of modern logic, and is classified as a deflationary theory, also known as correspondence theory.
One problem with the theory to be true is that the concept is unable to be applied to a natural language. This is because of Tarski's undefinability thesis, which says that no bivalent language can be able to contain its own predicate. Although English might seem to be an an exception to this rule but it does not go along with Tarski's view that all natural languages are closed semantically.
However, Tarski leaves many implicit restrictions on his theory. For example, a theory must not contain false sentences or instances of the form T. This means that a theory must avoid this Liar paradox. Another problem with Tarski's theories is that it isn't in line with the work of traditional philosophers. Furthermore, it's not able explain the truth of every situation in ways that are common sense. This is a major issue for any theory that claims to be truthful.
The other issue is that Tarski's definitions of truth is based on notions in set theory and syntax. These are not appropriate when considering endless languages. Henkin's approach to language is well-established, but it does not fit with Tarski's definition of truth.
Truth as defined by Tarski is also controversial because it fails provide a comprehensive explanation for the truth. Truth for instance cannot serve as a predicate in the interpretation theories as Tarski's axioms don't help explain the nature of primitives. In addition, his definition of truth does not fit with the concept of truth in meaning theories.
These issues, however, should not hinder Tarski from using his definition of truth, and it does not have to be classified as a satisfaction definition. The actual notion of truth is not so straightforward and depends on the particularities of object languages. If your interest is to learn more about it, read Thoralf's 1919 paper.
The problems with Grice's approach to sentence-meaning
The problems with Grice's understanding regarding the meaning of sentences could be summarized in two primary points. One, the intent of the speaker has to be recognized. In addition, the speech must be supported by evidence demonstrating the intended result. But these conditions are not satisfied in every instance.
This issue can be fixed through a change in Grice's approach to sentences to incorporate the meaning of sentences which do not possess intentionality. This analysis is also based on the notion sentence meanings are complicated entities that are composed of several elements. This is why the Gricean analysis fails to recognize any counterexamples.
This is particularly problematic when considering Grice's distinction between meaning of the speaker and sentence. This distinction is essential to any naturalistically based account of sentence-meaning. This theory is also necessary to the notion of conversational implicature. It was in 1957 that Grice developed a simple theory about meaning, which he elaborated in later writings. The principle idea behind the concept of meaning in Grice's work is to think about the speaker's intent in determining what the speaker is trying to communicate.
Another problem with Grice's study is that it doesn't make allowance for intuitive communication. For example, in Grice's example, it's not entirely clear what Andy uses to say that Bob is unfaithful toward his wife. But, there are numerous instances of intuitive communication that cannot be explained by Grice's research.
The main claim of Grice's model is that a speaker must aim to provoke an effect in audiences. This isn't intellectually rigorous. Grice decides on the cutoff in the context of indeterminate cognitive capacities of the interlocutor as well as the nature of communication.
The sentence-meaning explanation proposed by Grice isn't very convincing, though it's a plausible version. Different researchers have produced more thorough explanations of the meaning, but they're less plausible. In addition, Grice views communication as an activity that is rational. Audiences form their opinions because they are aware of the message being communicated by the speaker.
