Abstract
The advent of post-Humanism coincides with the crisis of Humanism. How did this crisis come about? This paper presents the Christian origins of Humanism until its transformation into the Enlightened Humanism. The crisis of Humanism brought by Heidegger and consummated by Sloterdijk and post-Humanist supposes, actually, the ideal of Enlightened Humanism, strongly criticized, for example, by Gray. At this crossroads the alternatives are the death of Humanism or the overcoming of the Enlightened model in search of a new humanism.
