	Ludwig Wittgenstein (Stanford Encyclopedia of Philosophy)
		Traditional metaphysics, and the propositions of ethics and aesthetics, which try to capture the world as a whole, are also excluded, as is the truth in solipsism, the very notion of a subject, for it is also not "in" the world but at its limit.
		The signs in language can only function when there is a possibility of judging the correctness of their use, "so the use of [a] word stands in need of a justification which everybody understands" (PI 261).
		What enables language to function and therefore must be accepted as "given" is precisely forms of life.

	Truth table - Wikipedia, the free encyclopedia
		Truth tables are used to compute the values of propositional expressions in an effective manner that is sometimes referred to as a decision procedure.
		Truth tables for classical logic are limited to Boolean logical systems in which only two logical values are possible, false and true, usually written F and T, or sometimes 0 or 1, respectively.
		Truth tables are a simple and straightforward way to encode boolean functions, however given the exponential growth in size as the number of inputs increase, they are not suitable for functions with a large number of inputs.

	Chapter IV
		A truth function which yields all truth values as "true" under the connective with the largest scope (as is the case in the example above) is recognized as an always-true truth function.
		A truth function which yields some truth values as "true" and others as "false" under the logical connective with the largest scope in a truth table is known as a contingent truth function.
		The negation of a contradictory truth function yields a tautologous truth function; negating a tautologous truth function yields a contradictory truth function.

	20th WCP: Truth and Religion Reconsidered: An Analytical Approach
		The intra-religious truth concerns the supernatural content of religious beliefs and its truth can be determined only from inside of a given religion by a believer through one's own revelation of God or through appeal to the authority of the divine founder of that religion.
		Truth of religion is here identified with religious truth understood as knowledge orientated towards the ultimate deepest reality called by various names: God, Dharma, Tao, the Sacred, etc. A religion is true in the sense that it states that the transcendent, supernatural, sacred reality exists.
		Truth of religion is seen in the intimate personal confrontation with the sacred and in all-embracing commitment of the person to the sphere of the sacrum.

	Truth function - Wikipedia, the free encyclopedia
		In mathematical logic, a truth function is a function from a set of truth-values to truth-values.
		Classically the domain and range of a truth function are {truth,falsehood}, but generally they may have any number of truth-values, including an infinity of them.
		Their values for various truth-values as argument are usually given by truth tables.

	Andrews. To Truth through Proof. (Site not responding. Last check: )
		Truth table semantics are given (as functions from propositional variables to the set {T,F}), along with the definitions of tautology [=valid in this context], contradiction, and satisfaction.
		An interpretation is a frame and a function mapping constants of Q0 to the appropriate domains, taking each Q to the appropriate identity relation (as a Curried characteristic function, of course), and taking the description operator to some map from sets of individuals to individuals that takes singletons to their unique element.
		Representability (of naturals, functions on naturals, and relations on naturals) is defined (as the existence of a closed formula such that Q0-inf proves it satisfies the appropriate equations on numerals to represent the function or relation).

	SPT v6n2: Davis Baird
		Truths connect how the world is with how we think it is. Functions connect how an artifact behaves with how we want it to behave.
		While it may seem the simplest function of functions, it is indeed deeply complex and problematic, and requires, finally, a closer examination.
		And then several of the early uses of photo-electric tubes relied on a different conceptualization of their function, namely that they produce "dark current," that is, current when no light is present and this dark current-or "noise" as the tube makers would have called it-was useful in the generation of radar jamming signals.

	Canonical forms of switching functions:
		We can derive from the truth table certain unique expressions which defines the function exactly; in fact, the expression is exactly equivalent to the truth table and consequently shares the properties of the truth table.
		The maxterm form of a function can be obtained from the truth table for a function by applying the principle of duality to the way described previously for deriving the minterm form of a function.
		It can be obtained easily from the truth table by ORing together all the variables or their complements which give a zero for the function; if the variable has value 0 then it is ORed directly, if it has a value 1, it is complemented.

	An Introduction To FUzzy Control Systems
		The concept of grades of truth or grades of membership in sets is something that, at this writing, does not seem to come naturally to many even though it is something that many of us actually use in making decisions in our life.
		In the usual case, the statement is either TRUE (value of the truth of the statement = 1) or it is FALSE (value of the truth of the statement = 0).
		For the composite function, the moment of the function is the integral of the function multiplied by the variable.

	SL-Semantics
		The values are the truth-values T and F. Hence, any given truth value assignment assigns either a T or an F to every atomic sentence of SL.
		Theses connectives are associatd with truth functions, and the truth of any molecular sentence of SL is a function of the truth-values of its atomic components.
		It is generated by using the operation of and on the atomic sentences L and M. And the truth-value of the molecular sentence is generated by applying the truth-function associated with the and on the truth values assigned to the atomics.

	Tractatus Logico-Philosophicus Introduction
		Thirdly, there is the problem of using sentences so as to convey truth rather that falsehood; this belongs to the special sciences dealing with the subject-matter of the sentences in question.
		A truth-function of a proposition p is a proposition containing p and such that its truth or falsehood depends only upon the truth or falsehood of p, and similarly a truth-function of several propositions p, q, r, . . .
		The meaning of the series of words which is a proposition is a function of the meaning of the separate words.

	9/11 Truth Portland - 9/11 Truth Portland
		We believe that by being clear about how we function as a group and what our expectations are of each other, new-comers can make an informed decision about whether they want to share in our work and if so, at what level.
		To this end, we also believe in personal accountability and the protection of our ability to function well was a group.
		Our mission is to ascertain the facts about the events of 9/11, to engage in ongoing dialogue with each other regarding the political context of the events and its significance, and to broaden the reach of the 9/11 truth movement among the political Left in Portland.

	Truth functions and propositional logic
		Hint: First try expressing truth functions which have exactly one T in their truth tables; then combine using ``or''.
		Proposition 4 Any truth function in n variables can be written in either disjunctive normal form (as a disjunction ``or'' of terms which are ``ands'' of variables and negations of variables) or conjunctive normal form (an ``and'' of terms which are ``ors'' of variables and negations of variables).
		Look at the truth tables to see that if all of the premises get a truth value of T then so do the conclusions.

	Propositions, truth tables, and valid forms of inference
		Since all of the statements of Theorems, Propositions, Lemata, and Corollaries are sentences with determinate truth value, all are propositions.
		Proposition 1.6 Any truth function in n variables can be written in either disjunctive normal form (as a disjunction ``or'' of terms which are ``ands'' of variables and negations of variables) or conjunctive normal form (an ``and'' of terms which are ``ors'' of variables and negations of variables).
		These results collectively give what is called functional completeness of the connectives sufficient to express all possible truth functions.

	Total Truth by Nancy Pearcey Official Site: Home
		David Limbaugh endorses Total Truth on his web site: “Pearcey is a scholar, an intellectual, a brilliant writer, and she has an uncanny ability to explain profound ideas in a way that is accessible—and helpful—to regular people.”
		Ultimately it reflects a division in the concept of truth itself, which functions as a gatekeeper, ruling Christian principles out of bounds in the public arena.
		Finally, she makes a passionate case that Christianity is not just religious truth but truth about total reality.
