Thierry Henry scored two of the Gunners' goals which now places them just three points behind Premiership leaders Liverpool.
Villa's Merson and Dion Dublin were a force to be reckoned with as Dublin headed on a pass to Merson who neatly sent the ball over Arsenal keeper Stuart Talyor.
In the 34th minute Stone picked up a poor clearance to make it 2-0.
With the London side trailing 2-0 at the close of the first half after a great counter-attack from Villa, it was a tense 15-minute break.
But the Gunners came through firing on all cylinders, with substitute Wiltord pulling one back with a volleyed goal before watching Henry fire in his two goals.
