  A number of lawyers and experts in the foundations of law introduced formal developments as well as analytic tools developed within ordinary language philosophy to study of the language of law. Regarding analytic tools, it is necessary to mention Carlos Cossio and Ambrosio Gioja from the Faculty of Law at the University of Buenos Aires. While neither of them is strictly speaking an analytic philosopher (both were trained within the phenomenological tradition) they introduced their students to new analytic readings in their seminars. Gioja introduced classical analytic texts in legal philosophy and ethics to young students participating in a reading group with him. Some of these young philosophers of law went on to become founders of the analytic tradition in the  country.[7] Many philosophers were interested in the analysis of ordinary language, especially Genaro  Carrió[8] and Eduardo Rabossi. Rabossi wrote on many issues. His most influential piece in ethics was the book La justificación moral del castigo (1976), and he also published Análisis filosófico, lenguaje y metafísica (1975), a book which introduced basic ideas  from the analytic tradition for the first time in Spanish. Posthumously, one of the most important works of his career was published, En el comienzo Dios creó el canon (2008; see below in  §3.3).[9]
