"That is mutualism, a noble mission of truth, sublime and holy mission mission of charity that nations ignore or have forgotten; nations, whose workers are dispersed, segregated, strangers to each other, and . . . how many times, sad to say, more than strangers, subject to ruinous enmities, that workers’ element divides instead of seeking [union], becomes offended instead of giving aid and, no, rejects with hatred its own [members] , rather than embracing [all workers] with love; [workers] reject each other without seeing that their blood and their anguish kneaded together become the bitter bread that they devour together; without seeing that their arms are what sustain the industry of nations, their richness and their greatness."
