The paper examines some problematic implications of the question whether there is place for an ethics in the philosophy of Martin Heidegger. This question has been repeatedly asked since his fundamental works were published and several authors have claimed they can see underlying associations of a practical nature in his thought, notwithstanding the determined and open rejection that the author himself often expressed with regard to such a possibility.    El presente trabajo intenta examinar algunas implicancias problemáticas suscitadas a la hora de preguntarse si en la filosofía de Martin Heidegger hay lugar para una ética. Esta pregunta ha sido formulada reiteradamente a partir de la publicación de sus obras fundamentales y no han sido pocos los que han querido ver concomitancias subyacentes de naturaleza práctica en su pensamiento, no obstante el decidido y manifiesto rechazo que el propio autor hizo a menudo evidente con respecto a tal posibilidad.
