Since the sixties, Lawrence Weiner has been one of the key figures in the field of conceptual art and the redefinition of the artistic object that goes along with it. Weiner’s conceptualism has focused on language, which he sees as a neutral, objective means through which to represent physical relationships with the outside world. He manages to eliminate references to the author's subjectivity through the specific use of words, declarations and affirmations in statements which he describes as sculptures. Some Objects of Desire, produced in 2004 to occupy one of the central walls of the MACBA building, is a huge 'mathematical equation' that emphasises the relationship between humans and physical objects. It is a descriptive, metaphorical work that affirm the relationship that exists between each of us and various kinds of things. As Weiner stated in his 1969 well known declaration of intent, his messages favour ideas rather than their materialisation.
