Once in Belgium, Proudhon did not fail to remain there. In 1859, after the general amnesty which followed the Italian war, he at first thought himself included in it. But the imperial government, consulted by his friends, notified him that, in its opinion, and in spite of the contrary advice of M. Faustin Helie, his condemnation was not of a political character. Proudhon, thus classed by the government with the authors of immoral works, thought it beneath his dignity to protest, and waited patiently for the advent of 1863 to allow him to return to France. In Belgium, where he was not slow in forming new friendships, he published in 1859-60, in separate parts, a new edition of his great work on "Justice." Each number contained, in addition to the original text carefully reviewed and corrected, numerous explanatory notes and some "Tidings of the Revolution." In these tidings, which form a sort of review of the progress of ideas in Europe, Proudhon sorrowfully asserts that, after having for a long time marched at the head of the progressive nations, France has become, without appearing to suspect it, the most retrogressive of nations; and he considers her more than once as seriously threatened with moral death. The Italian war led him to write a new work, which he published in 1861, entitled "War and Peace." This work, in which, running counter to a multitude of ideas accepted until then without examination, he pronounced for the first time against the restoration of an aristocratic and priestly Poland, and against the establishment of a unitary government in Italy, created for him a multitude of enemies. Most of his friends, disconcerted by his categorical affirmation of a right of force, notified him that they decidedly disapproved of his new publication. "You see," triumphantly cried those whom he had always combated, "this man is only a sophist."
