“The functions of the poetical faculty are two-fold; by one it creates new materials of knowledge, and power, and pleasure; by the other it engenders in the mind a desire to reproduce and arrange them according to a certain rhythm and order which may be called the beautiful and the good.  The cultivation of poetry is never more to be desired than at periods when, from an excess of the selfish and calculating principle, the accumulation of the materials of external life exceed the quantity of the power of assimilating them to the internal laws of human nature.  The body has then become too unwieldy for that which animates it.

“Poetry is indeed something divine.  It is at once the centre and circumference of knowledge; it is that which comprehends all science, and that to which all science must be referred.  It is at the same time the root and blossom of all other systems of thought; it is that from which all spring, and that which adorns all; and that which, if blighted, denies the fruit and the seed, and withholds from the barren world the nourishment and the succession of the scions of the tree of life.  It is the perfect and consummate surface and bloom of all things; it is as the odour and the colour of the rose to the texture of the elements which compose it, as the form and splendour of unfaded beauty to the secrets of anatomy and corruption.  What were virtue, love, patriotism, friendship—­what were the scenery of this beautiful universe which we inhabit—­what were our consolations on this side of the grave—­and what were our aspirations beyond it, if poetry did not ascend to bring light and fire from those eternal regions where the owl-winged faculty of calculation dare not ever soar?  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 intermixture of conventional expressions; a necessity only imposed by the limitedness
