“To call the taming of an animal its “improvement” is in our ears almost a joke. Whoever knows what goes on in menageries is doubtful whether the beasts in them are “improved”. They are weakened, they are made less harmful, they become sickly beasts through the depressive emotion of fear, through pain, through injuries, through hunger. – It is no different with the tamed human being…” - Friedrich Nietzsche, Twilight of the Idols
