Without the errors involved in the assumptions of ethics, man would have remained an animal. Thus has he taken himself as something higher and imposed rigid laws upon himself.
All animals go through interminable hard labor to produce what humans shamelessly rob from them at great physical/mental pain to them and to their young. THINK TWICE before using hot 'merchandise'!!!
Considered logically this concept is not identical with the totality of sense impressions referred to; but it is an arbitrary creation of the human (or animal) mind.
Evolution is not finished; reason is not the last word nor the reasoning animal the supreme figure of Nature. As man emerged out of the animal, so out of man the superman emerges.
Let the advocate of animal food, force himself to a decisive experiment on its fitness, and as Plutarch recommends, tear a living lamb with his teeth, and plunging his head into its vitals, slake his thirst with the steaming blood; when fresh from the deed of horror let him revert to the irresistible instincts of nature that would rise in judgment against it, and say, Nature formed me for such work as this. Then, and then only, would he be consistent.
I cannot see the short, white curls
Upon the forehead of an Ox,
But what I see them dripping with
That poor thing's blood, and hear the ax;
When I see calves and lambs, I see
Them led to death; I see no bird
Or rabbit cross the open field
But what a sudden shot is heard;
A shout that tells me men aim true,
For death or wound, doth chill me through.
