This article aims to show how Ortega y Gasset proposes a vocational, heroic and sportive ethic against, on the one hand, Kant's abstract and universalist idealism and, on the other hand, against the ethical nihilism of the era of the masses, which ends in utilitarian positivism and disorientation. This orteguian ethics also presents a mundane humanist character, far removed from all transcendentalism, and founded on the self-clarification of the subject. In this way, the subject can be lord and master of oneself to freely govern his existence and direct it toward the realization of the self. According to Ortega y Gasset, to hear vocation that calls us to be ourselves is what characterizes the moral subject, that is, the moral hero. 'To become oneself' is the concept that Ortega y Gasset proposes to fill the gap left by God's death announced by Nietzsche in the European soul.
