What Is Truth Condition Theory in Semantics

. A definition of truth determines the condition of truth for each sentence – that is, the necessary and sufficient conditions for its truth. The meaning of a sentence is then identified with its condition of truth because, as Carnap wrote: . A theory that would attribute conditions of truth (the conditions under which a particular sentence is true) to any sentence in the language, without using semantic terms, especially including truth, in that language. States of truth were identified by means of “T-phrases”. For example, the English T-phrase for the. Truth-based semantics is an approach to natural language semantics that sees meaning (or at least the meaning of assertions) as equal or reducible to their conditions of truth. This approach to semantics is mainly related to Donald Davidson and attempts to execute for natural language semantics what Tarski`s semantic theory of truth achieves for the semantics of logic. [1] In semantics, the truth condition of a sentence is almost generally considered different from its meaning. The meaning of a sentence is conveyed when the truth conditions of the sentence are understood. In addition, many sentences are understood, although their state of truth is uncertain. A popular argument in favor of this view is that some sentences are necessarily true, that is, they are true, no matter what.

All these sentences have the same conditions of truth, but probably do not have the same meaning. Similarly, the sets {x: x is alive} and {x: x is alive and x is not a rock} are identical – they have exactly the same members – but presumably the phrases “Nixon is alive” and “Nixon is alive and is not a rock” have different meanings. Some authors working in the field of pragmatics have argued that linguistic meaning, understood as the result of a purely formal analysis of a sentence type, underlies the conditions of truth. [3] [4] These authors, sometimes called “contextualists”[5], argue that the role of pragmatic processes is not only pre-semantic (disambiguation or assignment of reference) or post-semantic (drawing of implications, determination of speech acts), but also the key to determining the conditions of truth of a statement. For this reason, some contextualists prefer to speak of “truth-based pragmatics” rather than semantics. [6] [7] The first truth-based semantics was developed by Donald Davidson in Truth and Meaning (1967). She applied Tarski`s semantic theory of truth to a problem she was not supposed to solve, which was to give the meaning of a sentence. Scott Soames has sharply criticized truth-based semantics because it is either false or unnecessarily circular.

More formally, a condition of truth makes the truth of a sentence in an inductive definition of truth (for more details, see the semantic theory of truth). Understood in this way, the conditions of truth are theoretical entities. To illustrate with an example, suppose that in a particular theory of truth,[2] which is a theory of truth in which truth is made as acceptable as possible despite semantic terms, the word “Nixon” refers to Richard M. Nixon and “lives” is associated with all the things that are currently going on. One way to represent the truth condition of “Nixon is alive” is to represent the ordered pair . And we say that “Nixon lives” is true if and only if the speaker (or speaker of) “Nixon” belongs to the crowd associated with “is alive,” that is, if and only when Nixon is alive. Soames further argues that reformulations that attempt to explain this problem must raise the issue. If one specifies exactly which of the conditions of infinite truth of a sentence counts as its meaning, one must orient oneself on the meaning of the sentence. However, we wanted to specify meaning with conditions of truth, whereas now we specify conditions of truth with meaning, making the whole process fruitless.

[2] Faced with Quine`s skepticism, his student Donald Davidson made considerable efforts in the 1960s and 70s to revive its meaning.[2] Davidson tried to explain the meaning not in terms of behavior, but on the basis of the truth that was at that time. According to its traditional formulation, truth-based semantics gives exactly the same meaning to all necessary truths, because all are true under exactly the same conditions (i.e. all). And since the truth conditions of an unnecessarily true sentence correspond to the connection of these conditions of truth and any necessary truth, each sentence means the same as its meaning plus a necessary truth. For example, if “snow is white” is true, if and only if snow is white, then it is trivial that “snow is white” is true if and only if snow is white and 2 + 2 = 4, so “snow is white” under condition of semantic truth means that the geometry both snow is white and 2 + 2 = 4. Michael Dummett (1975) rejected Davidson`s program on the grounds that such a theory of meaning will not explain what a speaker needs to know to understand a sentence. Dummett believes that a speaker must know three components of a sentence in order to understand its meaning: a theory of meaning that specifies the part of the meaning that the speaker captures; A reference theory that specifies what claims about the world are made through the sentence, and a theory of force that specifies what kind of act of speech the expression performs. Dummett further argues that a theory based on inference, such as the semantics of proof theory, provides a better basis for this model than truth-based semantics. Truth-based semantic theories attempt to define the meaning of a given sentence by explaining when the sentence is true. For example, because “snow is white” is true, if and only when snow is white, the meaning of “snow is white” snow is white. In semantics and pragmatics, a condition of truth is the condition under which a sentence is true. For example, “It Snows in Nebraska” is true exactly when it snows in Nebraska.

The truth conditions of a sentence do not necessarily reflect the current reality. These are only the conditions under which the statement would be true. [1]. . . . . .
