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.
