This is just a review on his life of Milton. In it, Johnson chronicles the main events of Milton;s life and then critiques his literary writings in chronological order. His biography can be known elsewhere, and Johnson’s comments on it are usually not very germane to my purpose of understanding Paradise Lost or its author. Regarding Adam Unparadized, the rough draft for Paradise Lost, I believe Harold Bloom found the luminous detail in his essay on that work in The Western Canon. Of Milton's life, the most insightful were:
"It appears, in all his writings, that he had the usual concomitant of great abilities, a lofty and steady confidence in himself, perhaps not without some contempt of others, for scarcely any man ever wrote so much, and praised so few. Of his praise he was very frugal; as he set its value high, and considered his mention of a name as a security against the waste of time, and a certain preservative from oblivion."
Of Milton's Writing, Johnson had this cogent series of things to say:
Whatever be his subject, he never fails to fill the imagination. But his images and descriptions of the scenes or operations of nature do not seem to be always copied from original form, nor to have the freshness, raciness, and energy of immediate observation. He saw nature, as Dryden expresses it, “through the spectacles of books;” and on most occasions calls learning to his assistance. The garden of Eden brings to his mind the vale of Enna, where Proserpine was gathering flowers. Satan makes his way through fighting elements, like Argo between the Cyanean rocks, or Ulysses between the two Sicilian whirlpools, when he shunned Charybdis on the larboard. The mythological allusions have been justly censured, as not being always used with notice of their vanity; but they contribute variety to the narration, and produce an alternate exercise of the memory and the fancy.
His similes are less numerous, and more various, than those of his predecessors. But he does not confine himself within the limits of rigorous comparison: his great excellence is amplitude; and he expands the adventitious image beyond the dimensions which the occasion required. Thus, comparing the shield of Satan to the orb of the moon, he crowds the imagination with the discovery of the telescope, and all the wonders which the telescope discovers.
"He had considered creation in its whole extent, and his descriptions are therefore learned. He had accustomed his imagination to unrestrained indulgence, and his conceptions therefore were extensive. The characteristic quality of his poem is sublimity. He sometimes descends to the elegant, but his element is the great. He can occasionally invest himself with grace; but his natural port is gigantic loftiness. He can please when pleasure is required; but it is his peculiar power to astonish.
"Through all his greater works there prevails a uniform peculiarity of diction, a mode and cast of expression which bears little resemblance to that of any former writer; and which is so far removed from common use, that an unlearned reader, when he first opens his book, finds himself surprised by a new language.
"This novelty has been, by those who can find nothing wrong in Milton, imputed to his laborious endeavours after words suitable to the grandeur of his ideas. “Our language,” says Addison, “sank under him.” But the truth is, that, both in prose and verse, he had formed his style by a perverse and pedantic principle. He was desirous to use English words with a foreign idiom. This, in all his prose, is discovered and condemned; for there judgment operates freely, neither softened by the beauty, nor awed by the dignity of his thoughts; but such is the power of his poetry, that his call is obeyed without resistance, the reader feels himself in captivity to a higher and a nobler mind, and criticism sinks in admiration.
"Milton’s style was not modified by his subject; what is shown with greater extent in “Paradise Lost” may be found in “Comus.” One source of his peculiarity was his familiarity with the Tuscan poets; the disposition of his words is, I think, frequently Italian; perhaps sometimes combined with other tongues. Of him, at last, may be said what Jonson says of Spenser, that “he wrote no language,” but has formed what Butler calls a “Babylonish dialect,” in itself harsh and barbarous, but made by exalted genius and extensive learning the vehicle of so much instruction and so much pleasure, that, like other lovers, we find grace in its deformity."
