  Thomas Simpson was the intellectual mentor of generations of philosophers of language, most significantly Alberto Moretti, who in turn formed a new and powerful generation of analytic  philosophers.[15]  Eduardo Rabossi covered wider issues of philosophy and had students who focused on bioethics, Wittgenstein and 20th century philosophy, although most of his students focused on philosophy of  mind.[16]  Carlos Alchourrón and Eugenio Bulygin left many students working on the logic of norms, such as Hugo Zuleta and Ricardo  Caracciolo[17] and Alchourrón also had students focused in philosophical   logic.[18]  And, despite his early death, Carlos Nino also had many   students.[19]
