Abstract
Right after the presentation of Hyginus’s fable in §42 of Being and Time comes a note in which Heidegger affirms that the orientation about care as the being of Dasein (§41) arose in the context of the interpretation of Augustinian anthropology and the foundations obtained by the analysis of Aristotelian ontology. Why such a mention and why is it placed precisely after proving the pre-ontological origin of care as the being of Dasein? Assuming such problem, this paper does not aim only at offering a reading key that justifies such note, but at presenting the importance of the factical and pre-ontological aspects presented, respectively, in Book X of The Confessions of Augustine and in the fable of Hyginus for Heidegger's elaboration of care as an ontological category. For this purpose, three lecture courses will be assumed, especially: Augustine and Neo-Platonism (1921), which will make it possible to perceive the always factical aspect of care, thus evidencing the historical enactment perspective of the hermeneutics of facticity; Phenomenological Interpretations of Aristotle (1921/1922), which will make it possible to understand the idea of “ontological category” as a first formulation of what, in Being and Time, will be the existentials; and History of the concept of time: prolegomena (1925), which will allow us to realize that care is about being and not having, therefore, that it is not a possession of Dasein, but a condition of its existence. Finally, after justifying the importance of different aspects for care as an ontological category, it will be understood why the ontological interpretation differs from both others.
