The relation between a sign to its intended meaning can be known as the theory of meaning. It is in this essay that we'll be discussing the problems with truth conditional theories of meaning, Grice's theory of speaker-meaning and his semantic theory of truth. We will also look at evidence against Tarski's theories of truth.
Arguments against truth-based theories of meaning
Truth-conditional theories of Meaning claim that meaning is a function from the principles of truth. This theory, however, limits meaning to the linguistic phenomena. In Davidson's argument, he argues that truth-values are not always true. Therefore, we must be able to distinguish between truth-values as opposed to a flat assertion.
Epistemic Determination Argument Epistemic Determination Argument is a method to defend truth-conditional theories of meaning. It relies on two fundamental assumption: the omniscience of non-linguistic facts and understanding of the truth-condition. However, Daniel Cohnitz has argued against these assumptions. Thus, the argument is devoid of merit.
Another major concern associated with these theories is the lack of a sense of meaning. However, this issue is addressed through mentalist analysis. In this way, the meaning is analyzed in way of representations of the brain, instead of the meaning intended. For instance there are people who be able to have different meanings for the identical word when the same person is using the same word in the context of two distinct contexts but the meanings behind those words could be identical for a person who uses the same phrase in the context of two distinct situations.
Though the vast majority of theories that are based on the foundation of meaning try to explain the significance in the terms of content in mentality, non-mentalist theories are sometimes explored. This could be due some skepticism about mentalist theories. They could also be pursued with the view mental representations should be studied in terms of the representation of language.
Another significant defender of this idea An additional defender Robert Brandom. This philosopher believes that the meaning of a sentence dependent on its social context and that the speech actions involving a sentence are appropriate in what context in which they're utilized. Therefore, he has created a pragmatics model to explain sentence meanings by using socio-cultural norms and normative positions.
Issues with Grice's analysis of speaker-meaning
Grice's analysis based on speaker-meaning puts an emphasis on the speaker's intention , and its connection to the significance of the sentence. He believes that intention is an abstract mental state which must be understood in an attempt to interpret the meaning of the sentence. However, this approach violates the principle of speaker centrism, which is to analyze U-meaning without considering M-intentions. Furthermore, Grice fails to account for the reality that M-intentions can be restricted to just one or two.
In addition, the analysis of Grice doesn't account for important instances of intuitive communications. For instance, in the photograph example that was mentioned earlier, the subject cannot be clear on whether it was Bob or his wife. This is problematic because Andy's photograph doesn't indicate whether Bob is faithful or if his wife is unfaithful , or faithful.
While Grice believes that speaker-meaning has more significance than sentence-meaning, there is still room for debate. In reality, the difference is essential to the naturalistic reliability of non-natural meaning. In the end, Grice's mission is to provide naturalistic explanations to explain this type of meaning.
To understand a message one must comprehend the intent of the speaker, which is a complex embedding of intentions and beliefs. However, we seldom make profound inferences concerning mental states in regular exchanges of communication. Therefore, Grice's interpretation of meaning-of-the-speaker is not in accordance to the actual psychological processes involved in understanding language.
Although Grice's explanation for speaker-meaning is a plausible description in the context of speaker-meaning, it is still far from being complete. Others, like Bennett, Loar, and Schiffer, have created more detailed explanations. These explanations are likely to undermine the validity that is the Gricean theory since they regard communication as an activity rational. In essence, people trust what a speaker has to say due to the fact that they understand the speaker's motives.
Furthermore, it doesn't reflect all varieties of speech act. Grice's model also fails be aware of the fact speech acts are usually used to clarify the meaning of a sentence. The result is that the value of a phrase is reduced to its speaker's meaning.
Issues with Tarski's semantic theory of truth
While Tarski believes that sentences are truth-bearing but this doesn't mean a sentence must always be accurate. He instead attempted to define what constitutes "true" in a specific context. His theory has become a central part of modern logic and is classified as a correspondence or deflationary theory.
The problem with the concept for truth is it is unable to be applied to a natural language. This is due to Tarski's undefinability theorem, which states that no bivalent language is able to have its own truth predicate. While English might seem to be an a case-in-point and this may be the case, it does not contradict in Tarski's opinion that natural languages are semantically closed.
However, Tarski leaves many implicit limits on his theory. For example the theory should not include false sentences or instances of form T. This means that it is necessary to avoid the Liar paradox. Another flaw in Tarski's philosophy is that it's not as logical as the work of traditional philosophers. Furthermore, it's not able explain every single instance of truth in traditional sense. This is a major issue with any theory of truth.
The second issue is that Tarski's definition demands the use of concepts which are drawn from syntax and set theory. They are not suitable when looking at infinite languages. Henkin's style for language is well-established, but it doesn't support Tarski's concept of truth.
The definition given by Tarski of the word "truth" is also unsatisfactory because it does not explain the complexity of the truth. In particular, truth is not able to serve as an axiom in language theory, and Tarski's axioms do not provide a rational explanation for the meaning of primitives. Furthermore, his definition for truth is not in line with the concept of truth in sense theories.
But, these issues can not stop Tarski from using an understanding of truth that he has developed, and it does not fall into the'satisfaction' definition. In reality, the real definition of truth is less clear and is dependent on peculiarities of object language. If you're interested in knowing more, take a look at Thoralf's 1919 paper.
Problems with Grice's analysis of sentence-meaning
The issues with Grice's analysis of the meaning of sentences can be summarized in two main areas. The first is that the motive of the speaker must be understood. Second, the speaker's utterance must be supported with evidence that creates the intended outcome. However, these conditions aren't met in every case.
This problem can be solved by changing the analysis of Grice's sentence-meaning to include the meaning of sentences that do not have intention. This analysis is also based on the idea that sentences are highly complex and contain a variety of fundamental elements. So, the Gricean analysis is not able to capture examples that are counterexamples.
This critique is especially problematic with regard to Grice's distinctions between speaker-meaning and sentence-meaning. This distinction is fundamental to any naturalistically sound account of sentence-meaning. This is also essential in the theory of conversational implicature. The year was 1957. Grice gave a foundational theory for meaning, which was elaborated in later works. The core concept behind significance in Grice's work is to examine the speaker's intent in determining what message the speaker intends to convey.
Another problem with Grice's analysis is that it does not consider intuitive communication. For example, in Grice's example, it's not clear what Andy means by saying that Bob is not faithful and unfaithful to wife. However, there are plenty of counterexamples of intuitive communication that cannot be explained by Grice's argument.
The central claim of Grice's research is that the speaker must intend to evoke an effect in the audience. But this claim is not philosophically rigorous. Grice defines the cutoff with respect to contingent cognitive capabilities of the communicator and the nature communication.
Grice's theory of sentence-meaning isn't particularly plausible, although it's a plausible account. Other researchers have come up with deeper explanations of meaning, however, they appear less plausible. In addition, Grice views communication as a rational activity. Audiences justify their beliefs by observing the speaker's intent.
