igazságértékei

igazságértékei, meaning "truth values" in Hungarian, refers to the logical status of a proposition or statement. In classical logic, a proposition can only have one of two truth values: true or false. This binary system is fundamental to propositional calculus and predicate logic.

When a statement is true, its truth value is "true." Conversely, if a statement is false, its truth value is "false." These truth values are used to evaluate the validity of arguments and the consistency of logical systems. For instance, in a conditional statement like "If P, then Q," the truth value of the entire statement depends on the truth values of P and Q, according to specific rules of inference.

The concept of truth values extends beyond simple true/false. In some logical systems, such as fuzzy logic or multi-valued logic, propositions can possess intermediate truth values or a range of truth values, allowing for more nuanced representations of reality and uncertainty. However, the most common and foundational understanding of igazságértékei is within the bivalent (two-valued) framework of classical logic. Understanding truth values is crucial for comprehending how logical operations like conjunction, disjunction, and negation function and how complex propositions derive their truthfulness from simpler ones.
