Meh, we will have to disagree from nuance in perspective... Sure sure ...
The most careful ask to-day: “How is man to be maintained?” Zarathustra however asketh, as the first and only one: “How is man to be SURPASSED?”
The Superman, I have at heart; THAT is the first and only thing to me—and NOT man — Zarathustra
But what is Man to Nietzsche?
Zarathustra defines as strictly as possible what to him alone "man" can be,—not a subject for love nor yet for pity—Zarathustra became master even of his loathing of man: man is to him a thing unshaped, raw material, an ugly stone that needs the sculptor's chisel... — Nietzsche, Ecce Homo
Away from God and Gods did this will allure me; what would there be to create if there were—Gods!
But to man doth it ever impel me anew, my fervent creative will; thus impelleth it the hammer to the stone.
Ah, ye men, within the stone slumbereth an image for me, the image of my visions! Ah, that it should slumber in the hardest, ugliest stone!
Now rageth my hammer ruthlessly against its prison. From the stone fly the fragments: what’s that to me?
I will complete it: for a shadow came unto me—the stillest and lightest of all things once came unto me!
The beauty of the Superman came unto me as a shadow. Ah, my brethren! Of what account now are—the Gods to me!— — Zarathustra
What is the only time in which Nietzsche points directly to the Superman becoming reality?
See how Zarathustra goes down from the mountain and speaks the kindest words to every one! See with what delicate fingers he touches his very adversaries, the priests, and how he suffers with them from themselves! Here, at every moment, man is overcome, and the concept "Superman" becomes the greatest reality,—out of sight, almost far away beneath him, lies all that which heretofore has been called great in man. — Nietzsche, Ecce Homo
Or more precisely "und mit ihnen an ihnen leidet" to over come the animal compulsion to destroy but rather suffer with them from them... IE to "Suffer the fool," said Mr. Z "not pity the fool, Mr. T!"...
And the final nail in the coffin is from solving the riddles from The Vision and the Enigma within TSZ... we can clearly see the transformed being is one who overcomes their bad conscience, their shame and guilt...
And verily, what I saw, the like had I never seen. A young shepherd did I see, writhing, choking, quivering, with distorted countenance, and with a heavy black serpent hanging out of his mouth.
Had I ever seen so much loathing and pale horror on one countenance? He had perhaps gone to sleep? Then had the serpent crawled into his throat—there had it bitten itself fast.
My hand pulled at the serpent, and pulled:—in vain! I failed to pull the serpent out of his throat. Then there cried out of me: “Bite! Bite!
Its head off! Bite!”—so cried it out of me; my horror, my hatred, my loathing, my pity, all my good and my bad cried with one voice out of me.—
Ye daring ones around me! Ye venturers and adventurers, and whoever of you have embarked with cunning sails on unexplored seas! Ye enigma-enjoyers!
Solve unto me the enigma that I then beheld, interpret unto me the vision of the lonesomest one!
For it was a vision and a foresight:—WHAT did I then behold in parable? And WHO is it that must come some day?
WHO is the shepherd into whose throat the serpent thus crawled? WHO is the man into whose throat all the heaviest and blackest will thus crawl?
—The shepherd however bit as my cry had admonished him; he bit with a strong bite! Far away did he spit the head of the serpent—: and sprang up.—
No longer shepherd, no longer man—a transfigured being, a light-surrounded being, that LAUGHED! Never on earth laughed a man as HE laughed! — Zarathustra
So, I think, I'll have to go with the greater nuance of my understanding...
And by the way... WHO IS THE SHEPHERD?... Well none other than ...
A light hath dawned upon me. Not to the people is Zarathustra to speak, but to companions! Zarathustra shall not be the herd’s herdsman and hound! — Zarathustra
He says this after hiding his "dead" "companion" or rather a metaphor for Nietzsche himself...the transformation of himself in his opposite. The following is a further example...
People have never asked me as they should have done, what the name of Zarathustra precisely meant in my mouth, in the mouth of the first immoralist... Have I made myself clear? ... The overcoming of morality by itself, through truthfulness, the moralist's overcoming of himself in his opposite—in me—that is what the name Zarathustra means in my mouth. — Nietzsche, Ecce Homo, Fatality § 3
