logical consistency
Reasoning without contradictions
Logical consistency is the property of a set of statements or beliefs that contains no contradictions—nothing in the set rules out anything else.
A theory is logically consistent if all its claims can be true simultaneously.
The concept is central to philosophy, mathematics, and law, where internal contradictions invalidate arguments: The witness's testimony lacked logical consistency.
