O Goodness infinite, Goodness immense! 
  That all this Good of Evil shall produce, &c.

I have hinted in my sixth Paper on Milton, that an Heroick Poem, according to the Opinion of the best Criticks, ought to end happily, and leave the Mind of the Reader, after having conducted it through many Doubts and Fears, Sorrows and Disquietudes, in a State of Tranquility and Satisfaction.  Milton’s Fable, which had so many other Qualifications to recommend it, was deficient in this Particular.  It is here therefore, that the Poet has shewn a most exquisite Judgment, as well as the finest Invention, by finding out a Method to supply this natural Defect in his Subject.  Accordingly he leaves the Adversary of Mankind, in the last View which he gives us of him, under the lowest State of Mortification and Disappointment.  We see him chewing Ashes, grovelling in the Dust, and loaden with supernumerary Pains and Torments.  On the contrary, our two first Parents are comforted by Dreams and Visions, cheared with Promises of Salvation, and, in a manner, raised to a greater Happiness than that which they had forfeited:  In short, Satan is represented miserable in the height of his Triumphs, and Adam triumphant in the height of Misery.

Milton’s Poem ends very nobly.  The last Speeches of Adam and the Arch-Angel are full of Moral and Instructive Sentiments.  The Sleep that fell upon Eve, and the Effects it had in quieting the Disorders of her Mind, produces the same kind of Consolation in the Reader, who cannot peruse the last beautiful Speech which is ascribed to the Mother of Mankind, without a secret Pleasure and Satisfaction.

  Whence thou return’st, and whither went’st, I know;
  For God is also in Sleep, and Dreams advise,
  Which he hath sent propitious, some great Good
  Presaging, since with Sorrow and Heart’s Distress
  Wearied I fell asleep:  but now lead on;
  In me is no delay:  with thee to go,
  Is to stay here; without thee here to stay,
  Is to go hence unwilling:  thou to me
  Art all things under Heav’n, all Places thou,
  Who for my wilful Crime art banish’d hence. 
  This farther Consolation yet secure
  I carry hence; though all by me is lost,
  Such Favour, I unworthy, am vouchsafed,
  By me the promised Seed shall all restore.

The following Lines, which conclude the Poem, rise in a most glorious Blaze of Poetical Images and Expressions.

Heliodorus in his AEthiopicks acquaints us, that the Motion of the Gods differs from that of Mortals, as the former do not stir their Feet, nor proceed Step by Step, but slide o’er the Surface of the Earth by an uniform Swimming of the whole Body.  The Reader may observe with how Poetical a Description Milton has attributed the same kind of Motion to the Angels who were to take Possession of Paradise.
