Abstract: The decisive-set and pivotal-voter approaches have been used to prove Arrow's impossibility theorem. This study presents a proof using a proof calculus in logic. A valid deductive inference between the premises, the axioms and conditions of the theorem, and the conclusion, dictatorship, guarantees that every profile of all possible social welfare functions is examined, thereby establishing the theorem.
