After his illustration, Lewis says, “the act of self-will on the part of the creature, which constitutes an utter falseness to its creaturely position, is the only sin that can be conceived as the Fall.” God then began “ruling” Man not by the laws of the spirit but by the laws of nature. Therefore, the human spirit moved from being the master of human nature to become a mere lodger or prisoner in its own house. Lewis then says this condition was passed down biologically. He says that our present condition is because we are a part of a spoiled species, not that we’re suffering for the rebellion of remote ancestors.
