"The matters upon which the mass of the people, necessarily bent upon a livelihood, should ordinarily be called upon to pass judgment, are few and simple and fundamental. The perplexities of government and progress should be worked out by responsible representatives. But it is also true that the people should be left in the position easily and flexibly to register their opinion upon any matter whatsoever if it becomes necessary as a check upon reaction or because of a treasonable disregard by their representatives of their interests. And the spirit of the West is once more sound, from the broad standpoint of freedom and right, in its feeling that as things are in America, a measure of direct democracy is necessary in order to make representative government workable. But the initiative and referendum should be employed with restraint. It should be the gun behind the door, the remedy in emergency, the quick-acting but ultimate check upon substantial error and wrong."
