"Although Nietzsche had embarked upon the destruction of all idols, he too, in this way, recognized the desire for death inherent in the desire for truth at any cost. The philosopher who wants to examine all things 'in depth', discovers the petrifying abyss. The destiny of the man whom Nietzsche refers to as 'the Don Juan of knowledge' will be paralyzed as if by Medusa, and will himself be 'changed into a guest of stone' (Daybreak 327, 1881). This is also the destiny of the 'lover of truth' who, in the Dionysos Dithyramben (1888) appears to be 'changed into a statue/into a sacred column'. Nietzsche, who was aware of the necessity 'for the philosopher' to live within the 'closed circuit of representation' (Derrida), to seek the truth even if he no longer believes in it, without ever being able to attain it, devised his own version of the 'truth', his Medusa's head, the Eternal Return: 'Great thought is like Medusa's head: all the world's features harden, a deadly, ice-cold battle' (Posthumous Fragments, Winter 1884-5)."

DAY BREAK327. A FABLE .- The Don Juan of knowledge—no philosopher or poet has yet succeeded in discovering him. He is wanting in love for the things he recognizes, but he possesses wit, a lust for the hunting after knowledge, and the intrigues in connection with it, and he finds enjoyment in all these, even up to the highest and most distant stars of knowledge—until at last there is nothing left for him to pursue but the absolutely injurious side of knowledge, just as the drunkard who ends by drinking absinthe and aquafortis. That is why last of all he feels a longing for hell, for this is the final knowledge which seduces him. Perhaps even this would disappoint him, as all things do which one knows! and then he would have to stand still for all eternity, a victim to eternal deception, and transformed into his enemy, the Stony Guest, who longs for an evening meal of knowledge which will never more fall to his share! for the whole world of things will not have another mouthful left to offer to these hungry men.
