objective of his circles or meetings was "to train future worker leaders." In addition to his teaching at the Professional School, Arizmendiarrieta taught more than two thousand study circles, some for religious and human formation; others for social formation. This is equivalent to saying that he gave at least one conference every 2.7 days, for fifteen consecutive years, not discounting holidays and vacations. In any case, the Professional School was his favorite place of catholic and social apostolate. Every day at two in the afternoon he gave his 20-minute talk in the auditorium to professors and students of the 2nd year of Master's and Technical Engineering. The topics were diverse and unknown to the audience, such as Russian kolkhoz peasant cooperatives, Yugoslav self-management or German co-management. In addition to the content, his talks were difficult to understand due to his monotonous tone and difficult language. Aware of this, he used short quotes that were easy to remember such as “knowledge is power”, “knowledge must be socialized to democratize power”, “it is easier to educate a young person than to reform a man”, or “give a fish to a man and he will eat a day; teach him to fish and he will eat the rest of his life”. In the sermons at his daily mass in the parish he also used short quotations, to compensate for his difficult oratory. Once, the parishioners asked the bishopric to replace him because they did not understand him, but the bishop did not accept, valuing his social work more. And in July 1967, when he was invited to Madrid as a speaker in the debates on the future status of Spanish cooperativism, chaired by the General Director of Social Promotion, the attendees listened to him in silence because his oratory was difficult for them. To alleviate the situation, the Director told them "Keep in mind that Father Arizmendiarrieta thinks in Basque, and translates it into Spanish." Training and work Arizmendiarrieta had ascendancy over his collaborators because he led by example. His training curriculum vitae, written by himself, shows his dedication to his studies: "Philosophy and Theology" at the Seminary of Vitoria, "Ethical-Social" at the University of Comillas, enrolled in special intensive courses. And "Economics" in intensive courses at the Social School of Vitoria, from 1948 to 1952. He maintained close contact with the Vitoria Seminary, where year after year he attended the courses organized
