Demaría studied at Buenos Aires’ Colegio Champagnat, run by the priests of the Marian Order, whose dedication and rectitude represent a cornerstone in the poet’s life.
He then graduated in Philosophy at the University of Buenos Aires under the guidance of such humanists as Guillermo Thiele y Carlos Astrada, who made a decisive contribution towards defining his intellectual vocation.

Demaría's study of philosophy led him to the conviction that man's deepest conscience responds to sentiment and feeling rather than to ideas and rationality.
Editorial Dunken published the third and final part in 2007 under the name Tierra de Elegía, or Land of Elegy, a collection of love sonnets.
