Within these pages, we explore the theoretical, pedagogical, and charismatic foundations that sustain our work. If the Preventive System is a building, this volume reveals the invisible foundations that keep it standing against the cultural tremors of "liquid modernity." We approach the identity of the educator-pastor not as an unattainable ideal, but as a concrete, assessable, and livable profile. While Volume II will lead us into the territory of praxis in context and Volume III into the Salesian Preventive Leadership as a Theory as a model, and as leadership style, Volume I provides the cartography. In a world where roles are confused and boundaries are blurred; we must know with certainty what it means to be a Salesian educator today. We need objective assessment tools that allow us to say: "Here is where we stand," and "This is what we need to reach our goal.".
