The authors of the essays gathered here have approached the teaching of ethics from the border of the teacher and that of the disciple. Its central concern revolves around the possibility of transmitting ethical values ​​and knowledge in a world permeated by the crisis of reason. These proposals attempt a global approach to the problem that the teaching of ethics entails today through various paths such as the thought of Eduardo Nicol; the Renaissance epistolary texts of Marsilio Ficino; the experience of emptying that can be found in art; artistic, television and marketing productions; reading literary works, and, finally, rethinking nihilism in Nietzsche from a current perspective.
