Gutenberg Press, A Defence of Poetry, and Other Essays
Percy Bysshe Shelley wrote his essay A Defence of Poetry in 1821 although his widow did not have it published until 1840. Blake, who died in 1827, would have agreed with much of what Shelley wrote if he had had opportunity to read it.
Shelley wrote:
"Poetry is not like reasoning, a power to be exerted according to the determination of the will. A man cannot say, 'I will compose poetry.' The greatest poet even cannot say it; for the mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness; this power arises from within, like the colour of a flower which fades and changes as it is developed, and the conscious portions of our natures are unprophetic either of its approach or its departure. Could this influence be durable in its original purity and force, it is impossible to predict the greatness of the results; but when composition begins, inspiration is already on the decline, and the most glorious poetry that has ever been communicated to the world is probably a feeble shadow of the original conceptions of the poet. I appeal to the greatest poets of the present day, whether it is not an error to assert that the finest passages of poetry are produced by labour and study. The toil and the delay recommended by critics, can be justly interpreted to mean no more than a careful observation of the inspired moments, and an artificial connexion of the spaces between their suggestions by the intertexture of conventional expressions; a necessity only imposed by the limitedness of the poetical faculty itself; for Milton conceived the Paradise Lost as a whole before he executed it in portions; We have his own authority also for the muse having 'dictated' to him the 'unpremeditated song'. And let this be an answer to those who would allege the fifty-six various readings of the first line of the Orlando Furioso. Compositions so produced are to poetry what mosaic is to painting. This instinct and intuition of the poetical faculty, is still more observable in the plastic and pictorial arts; a great statue or picture grows under the power of the artist as a child in the mother's womb; and the very mind which directs the hands in formation is incapable of accounting to itself for the origin, the gradations, or the media of the process."
ON HOMERS POETRY, (E 269)
"Every Poem must necessarily be a perfect Unity, but why Homers is
peculiarly so, I cannot tell: he has told the story of
Bellerophon & omitted the judgment of Paris which is not only a
part, but a principal part of Homers subject
But when a Work has Unity it is as much in a Part as in the
Whole. the Torso is as much a Unity as the Laocoon ...
It is the same with the Moral of a whole Poem as with the Moral
Goodness
of its parts Unity & Morality, are secondary considerations &
belong to Philosophy & not to Poetry, to Exception & not to Rule,
to Accident & not to Substance. the Ancients calld it eating of
the tree of good & evil."
Jerusalem, Plate 3, (E 145)
"When this Verse was first dictated to me I consider'd a
Monotonous Cadence like that used by Milton & Shakspeare & all
writers of English Blank Verse, derived from the modern bondage
of Rhyming; to be a necessary and indispensible part of Verse.
But I soon found that
in the mouth of a true Orator such monotony was not only awkward,
but as much a bondage as rhyme itself. I therefore have produced
a variety in every line, both of cadences & number of syllables.
Every word and every letter is studied and put into its fit
place: the terrific numbers are reserved for the terrific
parts--the mild & gentle, for the mild & gentle parts, and the
prosaic, for inferior parts: all are necessary to each other.
Poetry Fetter'd, Fetters the Human Race! Nations are Destroy'd,
or Flourish, in proportion as Their Poetry Painting and Music,
are Destroy'd or Flourish! The Primeval State of Man, was Wisdom,
Art, and Science."
Letters, To Hayley, (E 705)
"Thirteen years ago. I lost a
brother & with his spirit I converse daily & hourly in the
Spirit. & See him in my remembrance in the regions of my
Imagination. I hear his advice & even now write from his
Dictate"
Visions of Daughters of Albion, Plate 27 [29], (E 125)
"But in Eternity the Four Arts: Poetry, Painting, Music,
And Architecture which is Science: are the Four Faces of Man.
Not so in Time & Space: there Three are shut out, and only
Science remains thro Mercy: & by means of Science, the Three
Become apparent in time & space, in the Three Professions
Poetry in Religion: Music, Law: Painting, in Physic & Surgery:"
Milton, Plate 41 [48], (E 142)
"To bathe in the Waters of Life; to wash off the Not Human
I come in Self-annihilation & the grandeur of Inspiration
To cast off Rational Demonstration by Faith in the Saviour
To cast off the rotten rags of Memory by Inspiration
To cast off Bacon, Locke & Newton from Albions covering
To take off his filthy garments, & clothe him with Imagination
To cast aside from Poetry, all that is not Inspiration"
Milton, Plate 41 [48], (E 142)
"These are the destroyers of Jerusalem, these are the murderers
Of Jesus, who deny the Faith & mock at Eternal Life:
Who pretend to Poetry that they may destroy Imagination;
By imitation of Natures Images drawn from Remembrance
These are the Sexual Garments, the Abomination of Desolation
Hiding the Human lineaments as with an Ark & Curtains
Which Jesus rent:"
Jerusalem, Plate 62, (E 213)
"Shall Albion arise? I know he shall arise at the Last Day!
I know that in my flesh I shall see God: but Emanations
Are weak. they know not whence they are, nor whither tend.
Jesus replied. I am the Resurrection & the Life.
I Die & pass the limits of possibility, as it appears
To individual perception. Luvah must be Created
And Vala; for I cannot leave them in the gnawing Grave.
But will prepare a way for my banished-ones to return
Come now with me into the villages. walk thro all the cities.
Tho thou art taken to prison & judgment, starved in the streets
I will command the cloud to give thee food & the hard rock
To flow with milk & wine, tho thou seest me not a season
Even a long season & a hard journey & a howling wilderness!
Tho Valas cloud hide thee & Luvahs fires follow thee!
Only believe & trust in me, Lo. I am always with thee!
So spoke the Lamb of God while Luvahs Cloud reddening above
Burst forth in streams of blood upon the heavens & dark night
Involvd Jerusalem. & the Wheels of Albions Sons turnd hoarse
Over the Mountains & the fires blaz'd on Druid Altars
And the Sun set in Tyburns Brook where Victims howl & cry.
But Los beheld the Divine Vision among the flames of the Furnaces
Therefore he lived & breathed in hope. but his tears fell incessant
Because his Children were closd from him apart: & Enitharmon
Dividing in fierce pain: also the Vision of God was closd in clouds
Of Albions Spectres, that Los in despair oft sat, & often ponderd
On Death Eternal in fierce shudders upon the mountains of Albion
Walking: & in the vales in howlings fierce, then to his Anvils
Turning, anew began his labours, tho in terrible pains!"
