"La Universidad debe ser el cerebro de un país, el centro donde se investiga, se planea, se discute cuanto dice relación al bien común de la nación y de la humanidad. Y el universitario debe llegar a adquirir la mística de que en el campo propio de su profesión no es sólo un técnico, sino el obrero intelectual de un mundo mejor."
