It is horrible! It is not the suffering and the death of the animals that is horrible, but the fact that the man without any need for so doing crushes his lofty feeling of sympathy and mercy for living creatures and does violence to himself that he may be cruel. The first element of moral life is abstinence.
Leo TolstoyHer face was brilliant and glowing; but this glow was not one of brightness; it suggested the fearful glow of a conflagration in the midst of a dark night.
Leo TolstoyWhen a man sees a dying animal, horror comes over him: that which he himself is, his essence, is obviously being annihilated before his eyes--is ceasing to be. But when the dying one is a person, and a beloved person, then, besides a sense of horror at the annihilation of life, there is a feeling of severance and a spiritual wound which, like a physical wound, sometimes kills and sometimes heals, but always hurts and fears any external, irritating touch.
