When a human kills an animal for food, he is neglecting his own hunger for justice. Man prays for mercy, but is unwilling to extend it to others. Why should man then expect mercy from God? It's unfair to expect something that you are not willing to give.
Isaac Bashevis SingerVarious philosophers and religious leaders tried to convince their disciples and followers that animals are nothing more than machines without a soul, without feelings. However, anyone who has ever lived with an animal-be it a dog, a bird, or even a mouse-knows that this theory is a brazen lie, invented to justify cruelty.
