Nietzsche, having spent his whole life stubbornly preaching the merits of what he called the will to power, stepped outside his Turin apartment one fine day to see a horse being beaten by its carriage driver. He cracked. Nietzsche threw himself between the driver and the horse, and he wrapped his arms around the horse, whispering in consoling tones.
Here's where it gets sketchy. Some people believe Nietzsche uttered one thing in this intimate moment with the horse (e.g., "Sing me a new song! The World is transformed, and all the Heavens sing for joy!"😉, some people say he said something else, and some people say he never spoke a word again. This third claim can be discarded, as there are still records available of letters Nietzsche wrote and conversations he had after being admitted to the asylum where he'd die after 11 years of largely incoherent madness; these letters are curious reads, but only because the guy is nutty as a fruitcake, and not because he's continuing to make a contribution to the fields of philosophy or philology.
As if these details weren't sketchy enough, there are many medical professionals/historians who believe that Nietzsche actually faked his affliction. There is even a conspiracy theory about his sister Elizabeth "setting the whole thing up" in an attempt to discredit him. While this is clearly ludicrous, it does serve to illustrate the reaction of the many devoted followers of the philosopher, who perceived the tale of his breakdown as a compromise of the strength he had preached.
What is more harmful than any vice? - Active sympathy for the ill-constituted and weak - Nietzsche
and in rebuttle
This is an old quote now common on the net
I would ask Nietzsche, What is a more explicit manifestation of weakness than to deny the receptiveness of the human mind to the world, to deny one's knowledge of the suffering of the horse, because one cannot handle it? Sympathy is no contemptible choice, it is neither contemptible nor choice, but rather a natural reflex of one's humanity, a receptiveness to the world that exists in all humankind, though he may try and fail to curtail or deny it. It is in such a way that humanity is connected to all the things it comprehends. And more sad and limiting than any other vice is it to deny what one necessarily feels because one is either too terrified of the truth or too weak to know and deal with the suffering of the horse, the suffering a human being vicariously endures proportionate to his knowledge of it.
Humanity pays for the fire of comprehension it has stolen from the gods by enduring the pain of all horses, by having access to all suffering. So Nietzsche vehemently denied; so Nietszche learned.
To omit sympathy from one's repetoire of feeling is to deny to understand. Nietzsche paid for his hubris.
