Quote from : Mr. Smith Goes to Washington Movie

Jefferson Smith: I guess this is just another lost cause, Mr. Paine. All you people don't know about lost causes. Mr. Paine does. He said once they were the only causes worth fighting for. And he fought for them once, for the only reason any man ever fights for them; because of just one plain simple rule: 'Love thy neighbor.'... And you know that you fight for the lost causes harder than for any other. Yes, you even die for them.
