Francisco Ferrer's The Origin and Ideals of the Modern School emerges from the shadow of his 1909 execution, presenting him not as a criminal, but as a rationalist reformer destroyed by a militarized and unjust society. In this powerful defense of his life and work, Ferrer explains how disillusionment with revolutionary politics led him to a deeper conviction: real social change must begin in education. He rejects violence, superstition, and sectarian dogma in favor of science, free inquiry, and the awakening of working-class minds. At the center of the book is the creation of the Modern School in Barcelona, a bold experiment in mixed, secular education for boys and girls, rooted in observation, historical awareness, moral responsibility, and concern for children's physical well-being. Ferrer recounts the struggles of founding the school, the need to train rationalist teachers, and the hostile resistance it faced. A pivotal influence is Mlle. Meunier, whose sincere intellectual journey leads her to fund the school after confronting the moral contradictions of inherited belief. Ferrer also broadens his argument into a critique of modern education itself: ruling classes know schools shape society, and they seek to control them for order, labor, and power. Against reformers who trust science alone to solve everything, he insists that education is inseparable from social struggle.
