'Animals' in the Bible

"As for human beings," I told myself, "God puts them to the test, that they might see themselves as mere animals."

For what happens to people also happens to animals a single event happens to them: just as someone dies, so does the other. In fact, they all breathe the same way, so that a human being has no superiority over an animal. All of this is pointless.

Who knows whether the spirit of human beings ascends, and whether the spirit of animals descends to the earth?
