classical truth-functional propositional logic, in which formulas are interpreted as having precisely one of two possible truth values, the truth value of true...

Many-valued logic (also multi- or multiple-valued logic) is a propositional calculus in which there are more than two truth values. Traditionally, in...

that logical truths are necessary truths. Instead he posits that the truth-value of any statement can be changed, including logical truths, given a re-evaluation...

both proposed ternary logics which have a third truth value representing that a statement's truth value is indeterminate. These logics have been applied...

output of a truth function are all truth values; a truth function will always output exactly one truth value, and inputting the same truth value(s) will always...

many-valued logic systems in which there are three truth values indicating true, false, and some third value. This is contrasted with the more commonly known...

truth-value links is a concept in metaphysics discussed in debates between philosophical realism and anti-realism. Philosophers who appeal to truth-value...

First, the values of the variables are the truth values true and false, usually denoted 1 and 0, whereas in elementary algebra the values of the variables...

Then the truth value of a sentence is defined to be its truth value under any variable assignment, and it is proved that this truth value does not depend...
