The gloomiest view of life as it now is, lies at the root of this story. Man’s days are mere hardship and labour and task-work, a task-work with no prospect of relief, for the only reward of it is that he returns to the earth from which he was taken. No thought appears of any life AFTER death, and life WITHOUT death might have been, but has been forfeited, now the cherub guards the approach to the tree of life, of which man might have eaten when in Paradise but did not. This actual, cheerless lot of man upon the earth is the real problem of the story. It is felt to be the very opposite of our true destiny; at first, things must have been otherwise. Man’s lot now is a perversion of what it was at first, it is the punishment of primeval guilt now resting on us all. At first man lived in Paradise; he had a happy existence, and one worthy of his nature, and held familiar intercourse with Jehovah; it was his forbidden striving after the knowledge of good and evil that drove him out of Paradise and brought all his miseries upon him.
What is the knowledge of good and evil? The commentators say it is the faculty of moral distinction,—conscience, in fact. They assume accordingly that man was in Paradise morally indifferent, in a state which allowed of no self-conscious action and could not be called either good or evil. A state like this not being an ideal one, some of them consider that man gained more than he lost by the fall, while others admit that it could not be the divine intention to keep him always at this stage of childish irresponsibility, and that this cannot be the view of the narrator either.
But it is plain that the narrator is not speaking of a relative prohibition of knowledge, but an absolute one: he means that it is only for God, and that when man stretches out his hand towards it he is transcending his limits and seeking to be as God. On the other side he cannot of course mean to say that conscience is a doubtful blessing, and its possession to be deplored, or that it is a thing that God in fact refuses to men and reserves to Himself alone. The knowledge spoken of cannot be moral knowledge. What could the assertion mean that God would have no one but Himself know the difference between good and evil, and would deny to man this knowledge? One would think that conscience is a thing belonging specifically to man and not to God.
