According to this view, it was not an autonomous ethic but reliance upon speculative knowledge which caused Adam and Eve's banishment from the garden of Eden. What the serpent promised is that reason can make us equal to God. Once Adam and Eve accepted that notion, they found they could no longer live in Paradise. First, when we look at creation with eyes wide open we discover that all is not good as Genesis claims. Reason denies the belief that everything God made was very good.
Reason explains that everything that exists has a beginning and an end.
To exist means to be imperfect, subject to decay and condemned to die. Secondly, reason leads to evil and sin because it asserts that every individual faces certain doom. History demonstrates that all persons are finite and will sooner or later be crushed as mercilessly as if they were inanimate objects. So reason tells us that we have to accept our fate. To be wise means to bow before the inevitable.
