proposicionális

Proposicional is a term that relates to propositions, which are declarative sentences that are either true or false. In logic and philosophy, proposicional logic, also known as sentential logic, is a fundamental branch that deals with the study of propositions and how they can be combined using logical connectives to form more complex propositions. These connectives include "and" (conjunction), "or" (disjunction), "not" (negation), "if...then..." (implication), and "if and only if" (biconditional).

The truth value of a compound proposition is determined by the truth values of its constituent propositions and the logical connective used. For example, the conjunction of two propositions is true only if both propositions are true. Proposicional logic provides a formal system for analyzing the validity of arguments and for reasoning about truth. It forms the basis for more advanced logical systems, such as predicate logic. The term proposicional can also refer to anything that pertains to or is characteristic of propositions themselves, such as proposicional attitudes, which are mental states that relate a person to a proposition, like believing, knowing, or doubting.
