The Millennium Development Goals (2030), committed to by the United Nations, have been configured as the horizon that humanity wants to give itself. An ambition as great as its complexity that, however, should not make us fall into the temptation of disenchantment or lack of individual commitment to its achievement. SDG 4, "Inclusive, equitable and quality education" is and will be, no one has the slightest doubt, the most important in order to guarantee the achievement of the rest of the Goals.
