tõeväärtuse

Tõeväärtus is an Estonian term that translates to "truth value" in English. It is a fundamental concept in logic and philosophy, referring to the property of a proposition or statement that it can be either true or false. In classical logic, there are only two possible truth values: true and false. These are often represented by symbols such as T and F, or 1 and 0.

The concept of truth value is crucial for evaluating the validity of logical arguments and for constructing formal systems of reasoning. A statement's truth value is determined by its correspondence to reality or by its logical consistency within a given system. For example, the statement "The sky is blue" has a truth value of true, assuming standard atmospheric conditions. Conversely, the statement "The sky is green" would have a truth value of false.

In more complex logical systems, such as fuzzy logic, the concept of truth value is extended beyond a binary true or false. Fuzzy logic allows for degrees of truth, where a statement can be partially true and partially false, represented by a value between 0 and 1. However, in classical propositional and predicate logic, the strict binary distinction of true or false remains central. Understanding tõeväärtus is essential for grasping the foundations of logical thought and its applications in mathematics, computer science, and artificial intelligence.
