Principle of Excluded Middle

The Principle of the Excluded Middle states that for any statement, either it is true or its opposite (false). There’s no middle ground or third option—no "maybe" or "unknown" state. For example, "The light is on" is either true (the light is on) or false (the light is off). This principle helps clarify logical reasoning by affirming that every statement must be one of these two options, providing a clear-cut way to evaluate the truth or falsehood of claims.
