A reflection inspired by a timeless proverb quoted by Cervantes: “When one door closes, another opens.” This article explores how every ending holds the seed of renewal and invites us to see closures not as losses, but as openings to growth, learning, and new possibilities.

Cuando el fanatismo de quienes gobiernan actualmente a Colombia se lleva por delante el derecho humanitario internacional y la Constitución Nacional, se hace obligatorio que los ciudadanos colombianos, los académicos y los intelectuales salgamos en defensa de esos valores.
