On January 3, 1889, Nietzsche, having spent his whole life stubbornly preaching the merits of what he called the will to power, witnessed a horse being beaten by its carriage driver on the Piazza Carlo Alberto in Turin, Italy. He cracked. He ran to the horse, threw his arms up around the horse’s neck to protect it, bursted into tears and collapsed to the ground. This collapse marks the outbreak of Nietzsche’s insanity. After this event the philosopher never wrote again and descended into madness and silence.
