How can you say you're trying to spiritually evolve, without even a thought about what happens to the animals whose lives are sacrificed in the name of gluttony?
A healthy-minded boy should feel hearty contempt for the coward and even more hearty indignation for the boy who bullies girls or small boys, or tortures animals.
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.
I do not see any reason why animals should be slaughtered to serve as human diet when there are so many substitutes. After all, man can live without meat.
It would be better if there were nothing. Since there is more pain than pleasure on earth, every satisfaction is only transitory, creating new desires and new distresses, and the agony of the devoured animal is always far greater than the pleasure of the devourer
The fact that man knows right from wrong proves his intellectual superiority to the other creatures; but the fact that he can do wrong proves his moral inferiority to any creatures that cannot.
