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]
Avicenna elaborated on his definition of truth later in Book VIII, Chapter 6: The truth of a thing is the property of the being of each thing which has been established in it. [75] This definition is but a rendering of the medieval Latin translation of the work by Simone van Riet. [76] A modern translation of the original Arabic text states:
Warburton says that one reason for the unreliability of the consensus theory of truth, is that people are gullible, easily misled, and prone to wishful thinking—they believe an assertion and espouse it as truth in the face of overwhelming evidence and facts to the contrary, simply because they wish that things were so. [1]: 135
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.
