The single-tax theory of political economics advanced by Henry George, having passed through the first of these three stages with something more than the usual publicity and controversy, has already been in its second stage for a good many years. The cessation of active discussion, which appears to some people to argue that it has passed into oblivion, or is at any rate well on the way toward such a consummation, is only evidence that it is in its second, or fermentation, period. Nobody can pretend for an instant that any one of the evils pointed out by Henry George as the things that called loudly for reform, have actually been reformed since the date of the publication of his original essay on "Progress and Poverty." No reasonable man can doubt that many, if not all of these evils, ought in some way to be dealt with, and if possible amended. While such is the case it is impossible wholly to get rid of the theory which trenchantly pointed out those evils and professed at least to offer an effective remedy. Under these conditions few things could be more desirable than that the matter should be advanced to the third of its natural stages by being submitted to the critical test of experience. Nothing short of this will ever satisfy the mass of mankind of the feasibility of the system proposed, or of its adequacy to meet the evils complained of; nothing less will set free the minds of many thousands of intelligent persons to inquire into other methods of reform than the fair trial of the single-tax system, and its failure to cure the evils which its author expected it to cure. The difficulty, which indeed is by no means a slight one, is to find a favorable arena in which the experiment can be tried, and a community prepared to make the experiment. It must be remembered that, if the evils aimed at by the proposed remedy of the single tax are great and far-reaching, its complete application could hardly, in most communities, amount to less than a practical revolution. Striking as it does at the whole received theory of land tenure, as sanctioned throughout the civilized world by the practice of many centuries, it arrays against itself the prejudices of the most influential classes in every long-established community, and its introduction is necessarily surrounded by difficulties and at least apparent injustices which must indefinitely delay any attempt to bring it to the test of experiment there. The only reasonable hope, indeed, of reducing the theory of the single tax to the plane of experience is to find a country not yet fully committed to any other system, and occupied by a self-governing people sufficiently intelligent to perceive the evils of other existing systems of land tenure, and sufficiently enterprising to be willing to experiment in this direction.
