This critical Text #15 (2023) collects many, almost all, of the texts written by Luis Moreno Mansilla throughout his career, many of them co-signed with his inseparable partner Emilio Tuñón. Arranged chronologically, they showcase the diverse subjects that interested him over the years, intertwined with the projects and competitions he worked on, the courses and lectures he delivered, the landscapes and cities he explored, and the countless topics his tireless curiosity led him to explore. Therefore, they are circumstantial, somewhat biographical. And although they do not aim to organize an abstract theory of architecture, they do exude an unexpected vocation for universality, as befits the sincere and luminous poetics of a genuine creator.

Together, these writings reveal Luis Moreno Mansilla’s way of thinking about architecture and life, two things that, for him, were inevitably intertwined. The immobile, perhaps foreign, space and the unstoppable time that we would like to capture but slips through our fingers, as Luis warned, blend together in these precise, delicate, acute, and lucid writings. In them, his refined sensitivity, penetrating intelligence, sense of humor, and infallible instinct for detecting the knots of the architectural landscape shape a territory of his own that Luis always wanted to share, in his elegant aspiration for personal and collective transformation, with a simple generosity that we, those fortunate enough to have known him like you, reader, can appreciate today.
