  Truth condition - Wikipedia, the free encyclopedia
To illustrate with an example: suppose that, in a particular truth theory, the word "Nixon" refers to Richard M. Nixon, and "is alive" is associated with the set of currently living things.
Then one way of representing the truth condition of "Nixon is alive" is as the ordered pair .
In semantics, the truth condition of a sentence is almost universally considered to be distinct from its meaning.

 Conditionals
If we knew the truth conditions of conditionals, we would handle uncertainty about conditionals in terms of a general theory of what it is to be uncertain of the truth of a proposition.
Conditional desires appear to be like conditional beliefs: to desire that B is to prefer B to ~B; to desire that B if A is to prefer AandB to Aand~B; there is no proposition X such that one prefers X to ~X just to the extent that one prefers AandB to Aand~B.
Extending Jackson's account to conditional commands, the doctor said "Make it the case that either the patient is not alive in the morning, or you change the dressing", and indicated that she would still command this if she knew that the patient would be alive.

 20th WCP: In Spite of Davidson's Arguments for "The Folly of Trying to Define Truth," Truth Can Be Defined
If Davidson abandoned the coherent theory of truth, as he concedes, and still retains the function of truth conditions in determining the truth and the meaning of our propositional beliefs, then the question is whether these truth conditions are themselves beliefs or not (Davidson, 1996:273, 1990:320).
Truth conditions cannot be elements of external reality to which we do not have direct access, but they cannot be just any cognitive states because then we would be in a vicious circle of holism.
The truth conditions of the perceptual judgments are the most rudimentary, they are feelings of duality of the indexical relation in the perceptual process and they are the indication of our confrontation with external reality.

It remains, though, apparently, that the thought lacks truth conditions of the sort intended by Kripke: conditions that determine whether a (possibly counterfactual) world is correctly described by the thought.
If the truth conditions of my thought are not terribly taxonomical, then that would seem to be an important fact about their nature -- the kind of fact that, according to absolutism, someone who knows what the truth conditions are ought to be cognizant of.
I know what the truth conditions of Goldbach's conjecture are and yet I am ignorant of as basic a fact as this about them: whether they are necessary or impossible.

 A QUESTION FOR EXPRESSIVISTS
Paul Horwich argues, drawing on his minimalist view of truth, that it follows from the point, granted by expressivists and their foes alike, that ethical sentences are meaningful, grammatically declarative ones, that they are truth apt, are truth assessable, or have truth conditions (for our purposes we need not distinguish these three notions).
It would, that is, be too quick to point out that indicative conditionals are sentences we produce as a result of our learned mastery of a natural language, and then conclude without further ado that they have truth conditions on the ground that they must, being convention-governed, express beliefs.
Incidentally, it might be argued that the reason `boo' and `hurrah' lack truth conditions is not that the conventions governing their use are not `good' enough, but rather that they belong with commands and recommendations.

 The Coherence Theory of Truth
The correspondence theory, in contrast, states that the truth conditions of propositions are not (in general) propositions, but rather objective features of the world.
Realism about truth involves acceptance of the principle of bivalence (according to which every proposition is either true or false) and the principle of transcendence (which says that a proposition may be true even though it cannot be known to be true).
One way to decide which account of truth conditions is correct is to pay attention to the process by which propositions are assigned truth conditions.

 Peter Suber, "Truth Trees for Propositional Logic"
Truth trees have all the virtues, and none of the vices, of all the known methods of testing validity.
They have the virtues that truth tables possess over derivations in that they are effective (dumb, mechanical, infallible); they test both validity and invalidity; they produce counterexamples in case of invalidity; and they may test validity directly on the argument or by testing its corresponding conditional for tautology.
Trees are superior to truth tables, and have the virtues of derivations, by remaining economical even with a very large number of variables, and by applying to both propositional and predicate logic.

 Semantics of logic - Open Encyclopedia   (Site not responding. Last check: 2007-10-09)
The truth conditions of various sentences we may encounter in arguments will depend upon their meaning, and so conscientious logicians cannot completely avoid the need to provide some treatment of the meaning of these sentences.
The semantics of logic refers to the approaches that logicians have introduced to understand and determine that part of meaning in which they are interested; the logician traditionally is not interested in the sentence as uttered but in the proposition, an idealised sentence suitable for logical manipulation.
Model-theoretic, of which the archetype is Alfred Tarski's semantic theory of truth, based on his T-schema, and is one of the founding concepts of model theory.

 UNIVERSALS
The standard style explanation is in terms of truth conditions: an argument is logically valid if and only if wholly general semantical considerations, based entirely the truth conditions of the premises and conclusion, insure that the premises cannot be true unless the conclusion is also true.
According to the standard conception of logical truth, a sentence is logically true if its truth is guaranteed by wholly general semantical considerations concerning the canonical truth conditions of it and its constituents.
Thus, a necessary condition for the truth of nominalism or conceptualism is not only that God exist but also that God have ideas of a kind that in principle we could not have and, indeed, that we could not know what it is like to have.

Either the truth conditions on moral judgments are objective--as in (1)--or there simply are no truth conditions on moral judgments--as in (3)--so that moral judgments are not properly judgments at all.
Either truth conditions on moral judgments are objective or truth conditions on moral judgments are subjective or there are no truth conditions on moral judgments.
Therefore, it is not the case that truth conditions on moral judgments are objective.

For the truth value of a sentence is fully determined by its truth condition and the relevant worldly facts.
A vindication of the deflationary conception of truth, worthwhile as it is, is clearly beyond the scope of this paper.
In accordance with his view of truth, he would presumably regard such a fact as the truth conditions of «lying is wrong».

 Philosophy Department - Proceedings of the Heraclitean Society
Anna's existence cannot be a truth condition for tokens of A (at least not one the two sides can agree upon, since any kind of agreement would require them to concede the conclusion each hopes to prove).
On the other hand, the presence of Anna and her reading material are not necessarily truth conditions of R according to the B-theorist.
Not assuming a tenseless ontology would have prevented him from justifiably claiming that the necessary and sufficient truth conditions merely include the tenseless fact that 1980 was occurring simultaneously with the occurrence of the token.

If the truth conditions of S and those of Q are both about an object, it seems that those of Sor Q will be about that object, so those of P3 are about Peter.
It seems that if the truth conditions of S are about an object, those of Q and S will be about that object, so those of P4 are about Peter.

 The Coherence Theory of Truth
The competing theories give conflicting accounts of the relation between propositions and their truth conditions.
Even though this fact obtains, however, the truth conditions of propositions, including propositions about which sets of propositions are believed, are the conditions under which they cohere with a set of propositions.

 20th WCP: A Neo-Formalist Approach to Mathematical Truth
The key idea is to distinguish the sense of a sentence from its explanatory truth conditions.
However it is not essential that the syntactic string named in the provability claim- the claim which forms part of the explanatory truth conditions- be distinct from the sentence which expresses the mathematical assertion.
Mathematical truth is thus linked, though not as part of the meaning of mathematical assertions, with provability in formal calculi, as the formalists thought, and in such a way as to be perfectly compatible with the claim that all that exists in mind-dependent reality are (perhaps finitely many) concrete objects together with their physical properties.

What we do know for free is that truth conditions can specify content, so much is enshrined in (TM); but this is not what Davidson is after, for (TM) is not informative in the right way, i.e., it is not the application of a truth predicate that makes content transparent where otherwise it is not.
A truth theory should do this precisely because it amounts to a test against the intuitive data that the theory records the information relevant to the understanding of the sentence in a way that explains how a sentence's meaning is composed from the meaning of its parts.
We can state a truth theory for a speaker (idiolect) in ways that satisfy constraints of novelty, compositionality, etc., and also offer intuitive tests of its correctness in the form of the demand that it entails articulations of the content of the speaker's sentences.

If there is truth that stands solidly against non-truth, there must be real consequences for every human being and every human situation regarding a person's refusal to examine that which is true against that which is not true.
To that reader who feels that an article regarding Christian truth and its implications to what is true in life (against what is not true) cannot possibly say anything to him or her, the author can only suggest that the reader give it a chance to do just that.
As Myths gather momentum, the whirling debris of the false viewpoint, rush into the wider world at large, bringing devastating consequences to the people who accept these myths, (within Christianity they are false doctrines) and attempt to live their lives as though they were true.

 What Truth Tables Do,   (Site not responding. Last check: 2007-10-09)
This is simple: the conditions under which the sentence is true (and, one might add, the conditions under which it is false).
Truth tables display these truth conditions by displaying the truth-values of complex sentences as determined ultimately by the truth-values of the simple sentences that are their components.
Truth tables can be applied to sets of sentences—in this case one can survey how each of the sentences truth-values vary with the combinations of truth-values of the components out of which they are constructed.

 PH38D Meaning as truth-conditions: Davidson
Frege's views that a declarative sentence expresses a Thought and denotes a truth-value, and that the meaning of expressions is to be given by stating their contributions to the meaning of the sentences in which they occur, together give his approach to meaning/sense a central concern with the conditions under which sentences are true.
Russell's analysis of definite descriptions is again a matter of spelling out how such expressions relate to the truth conditions of the sentences in which they occur.

 UH CogSci Lexicon: Truth Conditions   (Site not responding. Last check: 2007-10-09)
Truth-conditions of a sentence are those conditions which would make it true.
'Oedipus believed that he married his mother.' This is false, even though the sentence 'Oedipus believed that he married Jocasta' is true and the truth conditions for 'he married his mother' and 'he married Jocasta' are the same (since 'Jocasta' and 'Oedipus's mother' are coreferential).
In such contexts, the theory of meaning as truth-conditions fails to explain how the individual parts of a sentence contribute to the meaning of the sentence as a whole.
