  Truth - Wikipedia, the free encyclopedia
Truth is a property, just as red is a property predicated of a barn in the sentence in "The barn is red." The task for such theories is to explain the nature of this property.
Social constructivism holds that truth is constructed by social processes, is historically and culturally specific, and that it is in part shaped through the power struggles within a community.
The Indefinability theory of truth views the concept of truth along the same lines as a correspondence theorist, but it holds that truth cannot be defined in terms of simpler concepts.

On the one hand, there is truth as a broad, abstract concept that is applied to propositions, thoughts, beliefs, etc. On the other hand, there is truth as a body of important, profound, perhaps spiritual belief--Truth with a capital "T".
The original version of this bare-bones theory was called "the redundancy theory of truth", and it is due to F. Ramsey and Alfred Ayer, English philosophers who wrote their works in the 1920s and 1930s.
Truth, since it is knowable, is whatever the perfect science would tell us in the ideal limit of inquiry[?].

 Truth Tables for compound statements and arguments   (Site not responding. Last check: 2007-10-07)
If all of the truth values under the main connective (the conditional) are true (if the statement is a tautology) then the argument is VALID since it will not be possible for all of the premises to be true and the conclusion false.
If any of the truth values under the main connective are false, then the argument is INVALID since is is possible for the premises to all be true and the conclusion false (this is the only situation in which a conditional is false.
Notice that in the final row of the truth table for Modus Ponens, the truth value of the conditional is always true (a tautology if it were a statement), while in the final row of the truth table for Affirming the Consequent, there is one row where the conditional is false.

 Truth [Internet Encyclopedia of Philosophy]
The truth of the proposition that Saturn is the sixth planet from the Sun depends only on the physics of the solar system, and not in any obvious way on human convention.
The truth of noncontingent propositions comes about, they say — not through their correctly describing the way the world is — but as a matter of the definitions of terms occurring in the sentences expressing those propositions.
In this alternative theory, truth for a certain class of propositions, namely the class of noncontingent propositions, is to be accounted for — not in their describing the way the world is, but rather — because of certain features of our human linguistic constructs.

 Truth of Open Sentences
Sometimes it is difficult to determine the truth value of a sentence.
An even worse situation is the case where it is impossible to determine the truth value of a sentence due to a lack of information.
A variable is simply a spot waiting for a value.

 four valued logic   (Site not responding. Last check: 2007-10-07)
THE most important truth value of this logic is the third value "Paradox".
This third truth value is the truth value of the paradoxical proposition logically, for instance, the paradox, the possible propositions, the idea propositions, reflexive propositions.
Because this fourth valued proposition have actually time and space in our communication, this proposition that only imply the 4th truth value, have a form denying itself.

 The Truth Value of Statements Containing Names of Literary Characters as Subjects
Traditionally, the truth value of statements containing names of fictional, or literary, entities as subjects has posed a problem in the philosophy of language.
This is an odd implication, because the same statement seems to have a truth value in one instance and not have a truth value in another.
Had he taken my statement at face value (treated the subject as a singular referential term) and had a similar presupposition as mine (that "there exists in the actual world Jay Gatsby, and he is affluent"), then his statement would be false, as he affirmed as true a statement that lacked a truth value.

 Truth Tables for Compound Statements   (Site not responding. Last check: 2007-10-07)
The most difficult parts of constructing truth tables are the initial set-up of the table, and remembering the truth tables for the different logical connectives.
Notice that the pattern of the combinations of truth and falsity from the table for two simple statements appears in the columns under Q and R for the first four rows, and then repeats itself for the second four rows (5-8).
The conditions of truth and falsity for conditionals is the hardest of all the compound statements to understand.

 Truth_value   (Site not responding. Last check: 2007-10-07)
In logic, a '''truth value''', or '''truth-value''', is a value indicating to what extent a statement is true.
A simple intuitionistic logic has truth values of true, false, and unknown; fuzzy logic and other forms of multi-valued logic also use more truth values than simply true and false.
Other Boolean algebras may be used as sets of truth values in multi-valued logic, while intuitionistic logic generalises Boolean algebras to Heyting algebras.

 20th WCP: Can a truth value have causal power? A discussion of John Gibbons' "Truth in Action"
Based on such considerations, Gibbons' main claim is that the truth value somebody assigns to his or her beliefs has causal power.
This suggests that truth is causally relevant to ordinary end result types like stopping at a red light as well as their intentional counterparts."(p.6) So, B1* is not part of event E, because in E Marcia and Greg intended to ovoid getting a ticket according to aim1 and aim2.
The truth value is applied to the perceptual belief B* that by squeezing this lever, she will stop.

Another branch of normative ethics is theory of value; this looks at what things are deemed to be valuable.
Suppose we have decided that certain things are intrinsically good, or are more valuable than other things that are also intrinsically good.
These philosophers often view aesthetics and etiquette and arbitration as more fundamental, percolating 'bottom up' to imply, rather than explicitly state, theories of value or of conduct.

 Peter Suber, "The Short-Cut Method and Forking"
In the full truth table method for testing validity, we must construct all the rows of the table even if only some of them turn out to be relevant for the test of validity.
An "invalidating row" of a truth table (also called a "counterexample" to the argument) is a row in which every premise is true and the conclusion false.
The short-cut truth table method is a direct proof of invalidity, and an indirect proof of validity.

 Truth Value Assignment
HE TRUTH TABLE for a valid argument schema has no line on which the premises can be true while the conclusion is false; the truth table for an invalid argument, on the other hand, does have at least one such line.
When we construct a truth table for an argument schema, it is the absence or presence of such a line that identifies the schema as valid or invalid.
Assign numbers in sequence to the steps in which you first assign truth values to the various sentence letters, or to the steps in which you are able to narrow the possible options for the values which letters can have (e.g., if you determine that two letters must have opposite values).

 Contemporary Atheism Speaks Out In Humanist Manifesto 2000: Religion, Truth, and Value Without God
This is self-refuting, or self-contradictory: absolute truth is that there is no absolute truth; the absolute ethic is that all ethics are relative; and the objective worldview is that all worldviews are subjective.
Postmodern humanism is self-refuting: its absolute truth is that there is no absolute truth; its absolute ethic is that all ethics are relative; and its objective worldview is that all worldviews are subjective.
Despite the rejection of the existence of God based on what at first appear to be sophisticated philosophical and scientific arguments, atheism is a worldview that cannot account for the very universe in which we live, much less the immaterial aspects of reality such as minds, logic, ethics _ even numbers, concepts, and thoughts.

 Statements, truth values and truth tables
The truth value of a compound statement is determined from the truth values of its simple components under certain rules.
The lower case t and f were used to record truth values in intermediate steps.
Note that while a truth table involving statements p and q has 4 rows to cover the possibility of each statement being true or false, if we have additional information about either statement this will reduce the number of rows in the truth table.

 Ch3 Reference
A truth value assignment is an association of a single truth value with every atomic sentence.
You will have become familiar with partial truth value assignments from the tutorials even though we did not often use the name "partial": A row of a truth table represents a partial truth value assignment.
The partial truth value assignments to the atomic components of a sentence (or set of sentences) represent all possibilities for that sentence (or set of sentences).

 LESSON 03   (Site not responding. Last check: 2007-10-07)
Be able to write out the truth-tables for sentences of SL, and to determine the truth value of a sentence on a given truth-value assignment.
In the case of SL, we can get by with focussing on truth, because, in essence, we are concerned only with the meaning of the truth-functional connectives, and their meanings are given by their characteristic truth-tables (see Lesson 1).
In sentential logic, we use the concept of a truth-value assignment to play the role of a logical possibility, so that each row of a truth table is a logical possibility, and a truth table represents all logical possibilities for a given sentence or set of sentences.

Remarking that the proposition's truth is its corresponding to the fact that snow is white leads critics to request an acceptable analysis of this notion of correspondence.
Coherence Theories are valuable because they help to reveal how we arrive at our truth claims, our knowledge.
It would be circular to say that "X is consistent with Y" means "it is possible for X and Y both to be true together" because this response is presupposing the very concept of truth that it is supposed to be analyzing.

 Moments Of Truth: The Value Of The MCIF
Perhaps the value of the "MCIF" -- or Marketing Customer Information File -- would be better understood today if the generic name for these systems was more descriptive of how they are processed, how they function and how they are applied.
In many cases, institutions simply did not know who many of their valuable customers were.
In this way, the MCIF system is used where it matters the most -- at the Moments Of Truth where customers interface with cashiers, new accounts and service representatives; where the service is produced and where fact-based decisions must be made.

Within the framework of present mathematical logic, this principle can be interpreted in two differents ways: on the one hand taking Fregean truth to be simple truth (truth in a model), on the other hand to be logical truth.
The validity of (S1) in matrix's semantics is due to the fact that in this case the truth-value (under a given valuation) of a compound sentence is a function of the truth-values of its components.
