Temporal Logic

INTRODUCTION
English translation pending.
CORE DEFINITION
In the broad sense, temporal logic covers every formal approach to representing and reasoning about time and temporal information. In the narrow sense it names the modal-logic approach introduced by Arthur Prior in the 1950s under the name tense logic and developed by logicians and computer scientists after him. Its formulas are evaluated over structures of instants or intervals ordered by precedence, rather than over a single unchanging world.
SCAFFOLDING EFFECT
Reduce cognitive load
- Temporal assertion: rewrite claims like eventually or once into testable tense operators. - Track states: follow the truth value of one proposition from moment to moment. - Express constraints: state the ordering and duration requirements that specify acceptable system behavior.
Anchor fast decisions
Temporal logic treats expressions like always in the future or sometime in the past as modal operators whose semantics rest on a time structure, either instants with a precedence relation or intervals with relations among them. A future-tense assertion is true at a moment exactly when it holds at all later moments. Whether time is point-like or interval-like, linear or branching, directly determines which principles are valid.
