Taking what you say at face value, without asking anymore questions and digging deeper that might be so. But also that means that the animal life is useless and has no purpose and is not needed.
No, because animals have a purpose and usefulness in this life, where we do need them. Their purpose is real but it is tied to this world.
There’s nothing there to progress.
That’s true but that doesn’t mean they aren’t useful in this life. Something can have meaning for us here without continuing on after death, because we will continue on after death and we are affected by animals.
I’m not quite sure where you philosophy comes from, and I’d like to know;
Scripture and Tradition and scholastic philosophy. Scripture indicates that animals were created for man: “let them have dominion over the fish of the sea, and over the birds of the air, and over the cattle, and over all the earth, and over every creeping thing that creeps upon the earth.” (Genesis 1:26) And: “The fear of you and the dread of you shall be upon every beast of the earth, and upon every bird of the air, upon everything that creeps on the ground and all the fish of the sea; into your hand they are delivered. Every moving thing that lives shall be food for you; and as I gave you the green plants, I give you everything.” (Genesis 9:2-3)
It also indicates that animal life is tied to the existence of the body: “the life of [animal] flesh is in the blood.” (Lev. 17:14) This seems to imply that as goes the blood, so goes the soul.
St. John Damascene said: “All [animals], indeed, are for the seasonable use of man: but of them some are for food, such as stags, sheep, deer, and such like: others for service such as camels, oxen, horses, asses, and such like: and others for enjoyment, such as apes, and among birds, jays and parrots, and such like.” (Exposition of the Orthodox Faith Book 2)
From logic I think we can learn that animal souls don’t continue after death, as I think St. Thomas Aquinas shows: “no operation of the sensitive part of the soul can be performed without the body. In the souls of brute animals, however, there is no operation superior to those of the sensitive part, since they neither understand nor reason. This is evident from the fact that all animals of the same species operate in the same way, as though moved by nature and not as operating by art; every swallow builds its nest and every spider spins its web, in the same manner. The souls of brutes, then, are incapable of any operation that does not involve the body. Now, since every substance is possessed of some operation, the soul of a brute animal will be unable to exist apart from its body; so that it perishes along with the body.” (Summa Contra Gentiles Book II Chapter 82)
but I have read that other beings in the spiritual worlds emmanate through the animal life to gain experience. The whole point of life is to gain experience. And do some kind of work.
I don’t think that idea has any foundation in Catholic teaching.
