In 1861, after Garibaldi's expedition and the battle of Castelfidardo, Proudhon immediately saw that the establishment of Italian unity would be a severe blow to European equilibrium. It was chiefly in order to maintain this equilibrium that he pronounced so energetically in favor of Italian federation, even though it should be at first only a federation of monarchs. In vain was it objected that, in being established by France, Italian unity would break European equilibrium in our favor. Proudhon, appealing to history, showed that every State which breaks the equilibrium in its own favor only causes the other States to combine against it, and thereby diminishes its influence and power. He added that, nations being essentially selfish, Italy would not fail, when opportunity offered, to place her interest above her gratitude. To maintain European equilibrium by diminishing great States and multiplying small ones; to unite the latter in organized federations, not for attack, but for defence; and with these federations, which, if they were not republican already, would quickly become so, to hold in check the great military monarchies,--such, in the beginning of 1861, was the political programme of Proudhon. The object of the federations, he said, will be to guarantee, as far as possible, the beneficent reign of peace; and they will have the further effect of securing in every nation the triumph of liberty over despotism. Where the largest unitary State is, there liberty is in the greatest danger; further, if this State be democratic, despotism without the counterpoise of majorities is to be feared. With the federation, it is not so. The universal suffrage of the federal State is checked by the universal suffrage of the federated States; and the latter is offset in its turn by PROPERTY, the stronghold of liberty, which it tends, not to destroy, but to balance with the institutions of MUTUALISM. All these ideas, and many others which were only hinted at in his work on "War and Peace," were developed by Proudhon in his subsequent publications, one of which has for its motto, "Reforms always, Utopias never." The thinker had evidently finished his evolution. The Council of State of the canton of Vaud having offered prizes for essays on the question of taxation, previously discussed at a congress held at Lausanne, Proudhon entered the ranks and carried off the first prize. His memoir was published in 1861 under the title of "The Theory of Taxation." About the same time, he wrote at Brussels, in "L'Office de Publicite," some remarkable articles on the question of literary property, which was discussed at a congress held in Belgium, These articles must not be confounded with "Literary Majorats," a more complete work on the same subject, which was published in 1863, soon after his return to France.
