It is easy to represent "Paradise Lost" as obsolete by pointing out that its demonology and angelology have for us become mere mythology. This criticism is more formidable in appearance than in reality. The vital question for the poet is his own belief, not the belief of his readers. If the Iliad has survived not merely the decay of faith in the Olympian divinities, but the criticism which has pulverized Achilles as a historical personage, "Paradise Lost" need not be much affected by general disbelief in the personality of Satan, and universal disbelief in that of Gabriel, Raphael, and Uriel. A far more vulnerable point is the failure of the purpose so ostentatiously proclaimed, "To justify the ways of God to men." This problem was absolutely insoluble on Milton's data, except by denying the divine foreknowledge, a course not open to him. The conduct of the Deity who allows his adversary to ruin his innocent creature from the purely malignant motive "That with reiterated crimes he might Heap on himself damnation," without further interposition than a warning which he foresees will be fruitless, implies a grievous deficiency either in wisdom or in goodness, or at best falsifies the declaration: "Necessity and chance Approach me not, and what I will is fate." The like flaw runs through the entire poem, where Satan alone is resolute and rational. Nothing can exceed the imbecility of the angelic guard to which Man's defence is entrusted. Uriel, after threatening to drag Satan in chains back to Tartarus, and learning by a celestial portent that he actually has the power to fulfil his threat, considerately draws the fiend's attention to the circumstance, and advises him to take himself off, which Satan judiciously does, with the intention of returning as soon as convenient. The angels take all possible pains to prevent his gaining an entrance into Paradise, but omit to keep Adam and Eve themselves in sight, notwithstanding the strong hint they have received by finding the intruder "Squat like a toad, close at the ear of Eve, Assaying by his devilish art to reach The organs of her fancy, and with them forge Illusions as he list, phantasms and dreams."
