Cardinal Danielou: We admit that in the animal there may be the same type of biological existence as in men, but there is no soul. We believe that the soul is a human soul.
Srila Prabhupäda: Our Bhagavad-gitä says sarva-yonisu, “In all species of life the soul exists.” The body is like a suit of clothes. You have black clothes; I am dressed in saffron clothes. But within the dress you are a human being, and I am also a human being. Similarly, the bodies of the different species are just like different types of dress. There are soul, a part and parcel of God. Suppose a man has two sons, not equally meritorious. One may be a Supreme Court judge and the other may be a common laborer, but the father claims both as his sons. He does not make the distinction that the son who is a judge is very important and the worker-son is not important. And if the judge-son says, “My dear father, your other son is useless; let me cut him up and eat him,” will the father allow this?
