The paradox between truth and life according to Nietzsche

It is a question of restoring to the terrestrial life its founding ontological value. The life that up to now has been mutilated by the metaphysical truth negatively interested. It is thus of a playdoyer for the sacralization of the space-time multiform life, even by means of the truth if it affirms it, that it is about. In Nietzsche, have we found a reflexive and practical crutch allowing us to define ourselves permanently, as a true advocate of the life without which nothing has sense, including the substitute truth.
