Question: do animals Follow the law of progress like humans?
Answer: Yes, therefore, in the highest worlds, where people are more developed, the animals also developed more whiter and have sophisticated means of communication; but they are always below the man and subservient to him; they are his clever servant.
Question: do animals Progress, like a man, on his will or it happens by force of things [independently - another translation]?
Answer: the Force of things; so for them there is no redemption.
Question: In the upper worlds do animals know about God?
Answer: No, for them God, as once the spirits were gods to the people.
