According to Nietzsche, History is useful only if it transforms the present. Oblivion is the possibility for the unknown to occur. This doesn�t mean restricting all capacity for recollection. Instead, it is about relating history to the practise of suspicion. In so doing, there comes a detachment from the aim of objectivity, which entails a �really existing past�, in order to turn it into an active potential in the creation of values. In this way, the genealogist�s task of interpreting symptoms and withdrawing forces is constituted, facing the objective and universal history. We will also deal with the concept of amor fati, as an assertion about chance.
