Considerations from Areopagitica for the understanding of Milton: knowing good only by means of evil. How you can only know one if you know the other. How then the double fall of Adam and Eve requires Adam to know evil (that Eve has fallen) before he's eaten the fruit because she has. After her fall, and before Adam's, humanity both has and hasn't eaten the fruit (they're one person as far as that goes), and so knows good and evil before knowing good and evil. Thus he is already ruined ("me with the hath ruined," even before he eats. He chooses with full knowledge, and (it seems to me) chooses rightly.
