• "...the mission of those who, like us, wish the end of all oppression and of all exploitation of man by man, is to awaken a consciousness of the antagonism of interests between dominators and dominated, between exploiters and workers, and to develop the class struggle inside each country, and the solidarity among all workers across the frontiers, as against any prejudice and any passion of either race or nationality."
• "In all circumstances, it is the duty of the Socialists, and especially of the Anarchists, to do everything that can weaken the State and the capitalist class, and to take as the only guide to their conduct the interest of Socialism; or, if they are materially powerless to act efficaciously for their own cause, at least to refuse any voluntary help to the cause of the enemy, and stand aside to save at least their principles—which means to save the future."
• "..."France," or "Germany," and of other political and national agglomerations—results of historical struggles—as of homogenous ethnographic units, each having its proper interests, aspirations, and mission, in opposition to the interests, aspirations and a mission of rival units. This may be true relatively, so long as the oppressed, and chiefly the workers, have no self-consciousness, fail to recognize the injustice of their oppressors. There is, then, the dominating class only that counts; and this class, owing to its desire to conserve and to enlarge its power, even its prejudices and its own ideas, may find it convenient to excite racial ambitions and hatred, and send its nation, its flock, against "foreign" countries, with a view to releasing them from their present oppressors, and submitting them to its own political economical domination."
