A logical system is complete if every statement that is actually true within the system can be proved using its axioms and rules of inference. It means that no true statement within the system's scope is left unprovable.
Conditions: Applies to statements true within the system's scope.; Proof must use the system's axioms and rules of inference.

A logical system is consistent if it never proves both a statement and its opposite at the same time. Consistency ensures that there are no contradictions, which is essential for reliable conclusions.
Conditions: Applies to a logical system.; Concerns provability of a statement and its opposite.
