14. From the material point of view, the Church encourages efforts of international cooperation aimed at helping the poorer nations "in a better instruction of youth with a view to the future" (John Paul II, Address to the Diplomatic Corps [11 January 1986], n. 8:  Insegnamenti, IX, 1 [1986], 69-70). For "the illiterate is a starved spirit" (Paul VI, Encyclical Letter Populorum progressio [26 March 1967], n. 35) and illiteracy is "a kind of daily slavery in a world that presupposes education" (John Paul II, Message for World Day of Peace 1981, n. 3; see also his Address to the Brazilian Bishops of the North-Eastern region on the occasion of their ad limina Visit [30 September 1985], 4:  Insegnamenti, VIII, 2 [1985], 815-816). In another context, Pope John Paul II explained that the prime role of culture is to educate the person. The grave crises currently affecting the educational system in more affluent societies show that "the work of a human being's education is not carried out only with the help of institutions, with the help of organizational and material means, however excellent they may be", and that an education which places efficiency and performance before all else is doomed to failure. Education is a matter of teaching the human being to become "ever more human", to "be more" rather than to "have more". Thus the human being learns to "be" "with others", but even more to be "for others". That is why "education is of fundamental importance for the formation of inter-personal and social relations" (John Paul II, Address to UNESCO [2 June 1980], n. 11:  Insegnamenti III, 1 [1980], 1644).
