Explain the law of excluded middle as you would to a capable student, in 3-4 sentences.

The law of excluded middle states that for any proposition, either that proposition is true or its negation is true—there's no third option. For example, either "it is raining" is true or "it is not raining" is true, with no middle ground between these two possibilities. This principle is fundamental to classical logic and everyday reasoning, though some philosophers and mathematicians (called intuitionists) have questioned whether it applies to all statements, particularly in mathematics. The law essentially says reality doesn't allow for statements to be neither true nor false.
