Abstract

In the following paper we will attempt to offer a panoramic reconstruction of the relations between scientificity [Wissenschaftlichkeit] and the existentiell dimension of Dasein’s being in the framework of Being and Time and in the period immediately following its publication. To this end, we will attempt to (a) offer an account of the positive and negative appropriations of the concept of the existenziell in the reception of Heidegger's opus magnum, next (b) we will offer a systematic reconstruction of the existentiell dimension by recognizing what we will call developmental "vectors", and lastly, (c) we will review the fundamental moments of the ontological-critical science, and (d) show how each of this constitutive moments is affected by “existentiell unboundingness” [existenzielle Unverbindlichkeit].
