In semantics and pragmatics, a truth condition is the condition under which a sentence is true. For example, "It is snowing in Nebraska" is true precisely when it is snowing in Nebraska. Truth conditions of a sentence do not necessarily reflect current reality. They are merely the conditions under which the statement would be true. [1]
Truth-conditional semantics is an approach to semantics of natural language that sees meaning (or at least the meaning of assertions) as being the same as, or reducible to, their truth conditions. This approach to semantics is principally associated with Donald Davidson , and attempts to carry out for the semantics of natural language what ...
The truth conditions for quantified formulas are given purely in terms of truth with no appeal to domains whatsoever (and hence its name truth-value semantics). Game semantics or game-theoretical semantics made a resurgence mainly due to Jaakko Hintikka for logics of (finite) partially ordered quantification , which were originally investigated ...
A contemporary semantic definition of truth would define truth for the atomic sentences as follows: An atomic sentence F ( x 1 ,..., x n ) is true (relative to an assignment of values to the variables x 1 , ..., x n )) if the corresponding values of variables bear the relation expressed by the predicate F .
Truth or verity is the property of being in accord with fact or reality. [1] In everyday language, it is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.
Tarski's material adequacy condition, or Convention T, is: a definition of truth for an object language implies all instances of the sentential form (T) S is true if and only if P. where S is replaced by a name of a sentence (in the object language) and P is replaced by a translation of that sentence in the metalanguage.
A condition that must be satisfied for a statement to be true but is not sufficient on its own to guarantee the statement's truth. necessitation rule In modal logic , a rule stating that if a proposition is a theorem, then its necessity is also a theorem.
Or the conditions under which the consensus is conceived to be possible may be formulated as idealizations of actual conditions. A very common type of ideal consensus theory refers to a community that is an idealization of actual communities in one or more respects.
