+The Axiom of Choice is a foundational principle in [Set Theory](/wiki/set_theory), asserting that for any collection of non-empty sets, one can always select an element from each set. This [Axiom](/wiki/axiom), seemingly simple, has profound and often counter-intuitive implications, making it one of the most debated postulates in modern mathematics.
