(ANS – Rome) – When Don Bosco presented his Preventive System, he summarized it in three simple yet powerful words: reason, religion, and loving kindness. On these three pillars, he educated thousands of young people in Valdocco and in many other houses, and on these same foundations the Salesian world continues to build schools, oratories, and social works throughout the world. This is not an educational slogan, but a true “grammar of education,” capable of holding together the minds, hearts, and souls of young people.

For Don Bosco, reason means first and foremost helping young people understand the why behind rules and educational proposals. He did not limit himself to commanding or forbidding; instead, he explained, engaged in dialogue, reasoned with them, and sought to persuade through human and spiritual motivations. Salesian texts emphasize that “reason” implies rationality, clarity, and respect for the intelligence of young people, accompanying their growth not through emotional pressure but through the light of truth. Educating with reason means trusting a young person’s ability to understand what is good and to freely choose it. For this reason, the Salesian environment values dialogue, clear explanations, and the search for deeper motivations behind personal choices.

Religion stands at the heart of the Preventive System. Don Bosco was convinced that without reference to God, education remains incomplete. For this reason, he proposed a simple and accessible path of faith: age-appropriate catechesis, participation in Mass, frequent reception of the sacraments—encouraged but never imposed—and devotion to Mary Help of Christians. This is a popular, concrete, and joyful religiosity that accompanies daily life. One text recalls his conviction that “frequent confession and Communion and daily Mass are the pillars that must support the educational edifice.” At the same time, Don Bosco insisted that nothing should be forced. Faith must be proposed in a way that is attractive, serene, and liberating, so that it becomes a source of peace, meaning, and hope along the path of growth.

Loving kindness is perhaps the most distinctive term and, at the same time, the most difficult to translate. It does not refer to mere sentimental affection, but to an educational style marked by presence, trust, respect, and personal relationship. Don Bosco wanted young people “not only to be loved, but to know that they are loved.” Recent studies emphasize that loving kindness also includes attention to emotional maturity, the building of healthy relationships, and the educator’s ability to make themselves loved with authenticity. In this climate, correction does not humiliate but fosters growth; discipline is not an imposition but a form of help, because it arises within a relationship in which the young person knows they can trust.

Taken together, these three words explain why the Preventive System rejects violent punishment and seeks to minimize even severe sanctions, focusing instead on the development of inner responsibility. A young person placed in an environment where rules are reasonable and clearly explained (reason), where the presence of God is felt (religion), and where one experiences sincere care (loving kindness) is less likely to fall into serious error and, if they do, more willing to start again.

For this reason, even today, those who educate in the Salesian tradition can begin with these three words—few and simple, yet capable of educating generations, because they speak to the minds, hearts, and souls of young people.
