• "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."
• "...what seems to be elementary and fundamental for all Socialists (Anarchists, or others) is that it is necessary to keep outside every kind of compromise with the Governments and the governing classes, so as to be able to profit by any opportunity that may present itself, and, in any case, to be able to restart and continue our revolutionary preparations and propaganda."
• "...the oppressed are always in a state of legitimate self-defense, and have always the right to attack the oppressors."
