Even this One does not exist, my dear friend. I wish it were just that! But even if I accept to take up the gauntlet that you very skillfully threw to me, it still needs a lot of audacity since the above quote belongs in my opinion to the most significant thinker, poet, and philosopher of our days, to Nikos Kazantzakis. And I call him only a poet and not a writer because his books are not novels, they are poems.
In this respect, there are two words that I personally think we need to understand by ourselves since he is gone and we cannot ask him.The word 'One' and the word 'exist' (obviously).
