In the works of Friedrich Nietzsche, the conflict between the life and the face of the past is called the true task of Zarathustra and Nietzsche himself (se Ecco homo, KSA 6, 348). Nietzsche created a signal word for this conflict: 'it was'.
This paper analyzes the parts in Nietzsche's works where he used this idiosyncratic expression of the 'it was' as a sign for the conflict bewtween time and liffe. It can be said that the 'it was' was a central problem for the philosophy of Nietzsche that appeared troughout of his comparable short creative period.
Finally, the echo of Nietzsche's 'it was' in Heidegger's works will be critically discussed based on the prior analysis.
