Few men have had as much cultural and educational influence on their own countries as the philosopher and educator Antonio Caso (1883-1946). He was above all a patriot of his beloved Mexico, and he sought to deliver his humanitarian message to his countrymen. In his youth, after the revolt against Díaz, he was a member of the Ateneo de la Juventud, a group that sought to bring Mexico, spiritually and economically, back to the Mexicans. Caso realized that this effort involved the forming of a national consciousness among his people, whom he saw divided by their private and public interests. As an educator of Mexican youth for more than thirty years, Caso sought to imbue in his students the desire to search and to question. He saw education as a perpetual search for truth, and his own life and philosophy reflect this search. He rejected any system that proposed to describe all of reality, and he despised all dogmas-official or unofficial. He particularly fought against positivism and Marxism, systems current in his youth. The first part of this book is an introduction to the philosophical and educational ideas of Caso, as well as to the intellectual and political ideas in his life. Mr. Haddox skillfully shows the development of Caso's ideas and how they took shape from his own reading as well as from the experiences of his age and of his country. The second part contains Mr. Haddox's translations of selections from Caso's writings. They give a moving picture of Caso's hopes for Mexico and for humanitiy.
