Populorum Progressio §35

³⁵ We can even say that economic growth is dependent on social progress, the goal to which it aspires; and that basic education is the first objective for any nation seeking to develop itself. Lack of education is as serious as lack of food; the illiterate is a starved spirit. When someone learns how to read and write, he is equipped to do a job and to shoulder a profession, to develop self-confidence and realize that he can progress along with others. As We said in Our message to the UNESCO meeting at Teheran, literacy is the "first and most basic tool for personal enrichment and social integration; and it is society's most valuable tool for furthering development and economic progress." (36) We also rejoice at the good work accomplished in this field by private initiative, by the public authorities, and by international organizations. These are the primary agents of development, because they enable man to act for himself.
