"A person may be as radical as you please, and still may make an extremely conservative estimate of the force of necessity exhibited by a given set of conditions. A radical, for example, may think we should get on a great deal better if we had an entirely different system of government, and yet, at this time and under conditions now existing, he may take a strongly conservative view of the necessity for pitching out our system, neck and crop, and replacing it with another. He may think our fiscal system is iniquitous in theory and monstrous in practice, and be ever so sure he could propose a better one, but if on consideration of all the circumstances he finds that it is not necessary to change that system, he is capable of maintaining stoutly that it is necessary not to change it."
