This paper deals with prolegomenal stances necessary for a proper understanding of the paradoxical nature of Heidegger’s Being and Time. It shall be argued that Heidegger’s magnum opus does not inquire into the sense of being in order to render an answer to the so called Seinsfrage. In fact, several answers have already been given traditionally, which are founded on the being/entity indifferentiation (being as God, substance, nature, subject and so forth), that is, being has been turned into a topic, (...) whilst it is essentially non-topical, for only an entity can be accounted for as topical or thematic. This is the reason why assessing Heidegger as the “thinker of being” can be misleading, if not overtly wrong, when by this is meant that being be conceived of as something that can be thematized.
