We have seen something of the principle underlying the Liberal idea and of its various applications. We have now to put the test question. Are these different applications compatible? Will they work together to make that harmonious whole of which it is easy enough to talk in abstract terms? Are they themselves really harmonious in theory and in practice? Does scope for individual development, for example, consort with the idea of equality? Is popular sovereignty a practicable basis of personal freedom, or does it open an avenue to the tyranny of the mob? Will the sentiment of nationality dwell in unison with the ideal of peace? Is the love of liberty compatible with the full realization of the common will? If reconcilable in theory, may not these ideals collide in practice? Are there not clearly occasions demonstrable in history when development in one direction involves retrogression in another? If so, how are we to strike the balance of gain and loss? Does political progress offer us nothing but a choice of evils, or may we have some confidence that, in solving the most pressing problem of the moment, we shall in the end be in a better position for grappling with the obstacles that come next in turn? I shall deal with these questions as far as limits of space allow, and I will take first the question of liberty and the common will upon which everything turns. Enough has already been said on this topic to enable us to shorten the discussion. We have seen that social liberty rests on restraint. A man can be free to direct his own life only in so far as others are prevented from molesting and interfering with him. So far there is no real departure from the strictest tenets of individualism. We have, indeed, had occasion to examine the application of the doctrine to freedom of contract on the one hand, and to the action of combinations on the other, and have seen reason to think that in either case nominal freedom, that is to say, the absence of legal restraint, might have the effect of impairing real freedom, that is to say, would allow the stronger party to coerce the weaker. We have also seen that the effect of combination may be double edged, that it may restrict freedom on one side and enlarge it on the other. In all these cases our contention has been simply that we should be guided by real and not by verbal considerations,--that we should ask in every case what policy will yield effective freedom--and we have found a close connection in each instance between freedom and equality. In these cases, however, we were dealing with the relations of one man with another, or of one body of men with another, and we could regard the community as an arbiter between them whose business it was to see justice done and prevent the abuse of coercive power. Hence we could treat a very large part of the modern development of social control as motived by the desire for a more effective liberty. The case is not so clear when we find the will of the
