Abstract: The matrix of rational thought, product of Modernity, is presented as the par excellence mode of science production, proper to a hegemonic model today. Of great effectiveness in many fields, in the humanities its totalizing presentation does not answer all the questions. I chose the question of humanism, one of the themes that Martin Heidegger presents in a discussion that took place immediately after the war, in a somewhat dangerous as well as misunderstood way of questioning concepts proper to conceptual metaphysics. In contemporary times, the restlessness about humanism and the possibilities of its understanding becomes imperative.
