The paper analyzes, from a perspective which is itself existential-ontological, the way in which in an early text of Martin Heidegger, Phanomenologische Interpretationen zu Aristoteles (Anzeige der hermeneutischen Situation) [1922] - which had already outlined some determinative elements of the ideas expounded in Being and Time -, the meditation on the always living and current conditions and hermeneutical situation of philosophizing expanded in fact into an inquiry about the origins, grounds, essence and sense of philosophy as such. Meditation in and through which philosophy identifies itself and is founded on the one hand exactly as a mode of existence of the mortal "human Dasein" (menschliches Dasein), that is a factic mode of existence of this, philosophy, on the other hand, itself originates from and in man's factic life exactly with the aim of being the modality through which this being - namely ourselves - returns towards the problematization of his existential possibilities even by taking upon himself the burden and "weight" of radical interrogation. Which therefore goes and must go itself and resolutely - because if this entirely "without God" and consequently a-theist - to the historical and ontological roots of a present con-temporarized (mitzeitigt) both with the past and the future existential horizons of the assumed factic possibilities.
