For our continued influxes of feeling are modified and directed by our thoughts, which are indeed the representatives of all our past feelings; and, as by contemplating the relation of these general representatives to each other we discover what is really important to men, so, by the repetition and continuance of this act, our feelings will be connected with important subjects, till at length, if we be originally possessed of much sensibility, such habits of mind will be produced, that, by obeying blindly and mechanically the impulses of those habits, we shall describe objects, and utter sentiments, of such a nature and in such connection with each other, that the understanding of the being to whom we address ourselves, if he be in a healthful state of association, must necessarily be in some degree enlightened, and his affections ameliorated.
I have said that each of these poems has a purpose. I have also informed my Reader what this purpose will be found principally to be: namely to illustrate the manner in which our feelings and ideas are associated in a state of excitement. But, speaking in language somewhat more appropriate, it is to follow the fluxes and refluxes of the mind when agitated by the great and simple affections of our nature. This object I have endeavoured in these short essays to attain by various means; by tracing the maternal passion through many of its more subtle windings, as in the poems of the IDIOT BOY and the MAD MOTHER; by accompanying the last struggles of a human being, at the approach of death, cleaving in solitude to life and society, as in the Poem of the FORSAKEN INDIAN; by shewing, as in the Stanzas entitled WE ARE SEVEN, the perplexity and obscurity which in childhood attend our notion of death, or rather our utter inability to admit that notion; or by displaying the strength of fraternal, or to speak more philosophically, of moral attachment when early associated with the great and beautiful objects of nature, as in THE BROTHERS; or, as in the Incident of SIMON LEE, by placing my Reader in the way of receiving from ordinary moral sensations another and more salutary impression than we are accustomed to receive from them. It has also been part of my general purpose to attempt to sketch characters under the influence of less impassioned feelings, as in the TWO APRIL MORNINGS, THE FOUNTAIN, THE OLD MAN TRAVELLING, THE TWO THIEVES, characters of which the elements are simple, belonging rather to nature than to manners, such as exist now, and will probably always exist, and which from their constitution may be distinctly and profitably contemplated.
