Context

“There a something unnatural about these fellows. Do not listen to their gospel, Senor Commander: it is dangerous. Beware of the pursuit of the Superhuman: it leads to an indiscriminate contempt for the Human. To a man, horses and dogs and cats are mere species, outside the moral world. Well, to the Superman, men and women are a mere species too, also outside the moral world. This Don Juan was kind to women and courteous to men as your daughter here was kind to her pet cats and dogs;” source
