Abstract
The analysis of Dasein’s modes of being (authentic, inauthentic and original) shows us that originality has a close relation with authenticity. Originality is not an ontological dimension in opposition to authenticity and inauthenticity which are ontical dimensions, but the ontological beingtowards- death and the authentic and ontic resoluteness composes it. If that is the fact, then temporality cannot be conceived as an original and indifferent phenomenon that explains the movement from inathenticity to authenticity and the other way round. Our hypothesis is that this movement can only be explained by speech, i.e. vocation and ‘temptation’, but that Heidegger despised this fact, due to his methodological goal of having only one phenomenon, time, as sense of being
