It has been twenty years since the physical death of Jacques Derrida. Yet his legacy seems to be extraordinary alive and rich in a work which is profusely studied, which gives what to think in the sense about how it is possible to use his theoretical anal- yses to "think" in another way the world's problems both in the philosophical, political and sociocultural fields. Derrida's thought represents -perhaps more than ever- an enigmatic challenge for the 21st st century scholar. This paper aims a call to what could be "his name" in a "tribute" based on what Derrida called himself a "work of mourning" from the memory of the absent. He questions "what's left?", "is there any kind of surplus (of life, of meaning) which remains?". I seek therefore not exactly a homage to Derrida's death but rather to take some terms closely related themselves in Derrida's thought, in a way alike to what himself sought through concepts like diff & eacute;rance, , deconstruction, , double session, , spectrum, , among others.
