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 ...
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 .
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.
Revelation may be defined as truth emanating from God. Many religions fundamentally rely on revelation as a test of truth. This criterion is subject to the same criticisms as intuition. It may be a valid reference of truth for an individual, but it is inadequate for providing a coherent proof of the knowledge to others. [14]
By using the schema one can give an inductive definition for the truth of compound sentences. Atomic sentences are assigned truth values disquotationally.For example, the sentence "'Snow is white' is true" becomes materially equivalent with the sentence "snow is white", i.e. 'snow is white' is true if and only if snow is white.
Ground truth is information that is known to be real or true, provided by direct observation and measurement (i.e. empirical evidence) as opposed to information provided by inference. Etymology [ edit ]
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.
